Background of the Invention
[0004] This invention relates generally to oil and gas exploration, and in particular to isolating certain subterranean zones to facilitate oil and gas exploration.
[0005] During oil exploration, a wellbore typically traverses a number of zones within a subterranean formation. Some of these subterranean zones will produce oil and gas, while others will not. Further, it is often necessary to isolate subterranean zones from one another in order to facilitate the exploration for and production of oil and gas. Existing methods for isolating subterranean production zones in order to facilitate the exploration for and production of oil and gas are complex and expensive.
[0006] The present invention is directed to overcoming one or more of the limitations of the existing processes for isolating subterranean zones during oil and gas exploration.

Another end 210cof the slotted tubular member 210 is coupled to an end 212aof a slotted tubular member 212 that defines a passage 212bby a conventional threaded connection. A pre-expanded end 214aof a second expandable tubular member 214 that defines a passage 214bis coupled to the other end 212cof the tubular member 212. The second expandable tubular member 214 further includes an unexpended intermediate portion 214c, another pre-expanded end 214d, and a sealing member 214ecoupled to the exterior surface of the unexpended intermediate portion. In an exemplary embodiment, the inside and outside diameters of the pre-expanded ends, 214aand 214d, of the second expandable tubular member 214 are greater than the inside and outside diameters of the unexpended intermediate portion 214c.
[0100] An end 216aof a slotted tubular member 216 that defines a passage 216bis coupled to the other pre-expanded end 214dof the second expandable tubular member 214 by a conventional threaded connection. Another end 216cof the slotted tubular member 216 is coupled to an end 218aof a slotted tubular member 218 that defines a passage 218bby a conventional threaded connection.

The third expandable tubular member 220 further includes an unexpended intermediate portion 220c, another pre-expanded end 220d, and a sealing member 220ecoupled to the exterior surface of the unexpended intermediate portion. In an exemplary embodiment, the inside and outside diameters of the pre-expanded ends, 220aand 220d, of the third expandable tubular member 220 are greater than the inside and outside diameters of the unexpended intermediate portion 220c.
[0101] An end 222aof a tubular member 222 is threadably coupled to the end 30dof the third expandable tubular member 220.
[0102] In an exemplary embodiment, the inside and outside diameters of the pre-expanded ends, 206a, 206d, 214a, 214d, 220aand 220d, of the expandable tubular members, 206, 214, and 220, and the slotted tubular members 210, 212, 216, and 218, are substantially equal. In several exemplary embodiments, the sealing members, 206e, 214e, and 220e, of the expandable tubular members, 206, 214, and 220, respectively, further include anchoring elements for engaging the wellbore casing 104. In several exemplary embodiments, the slotted tubular members, 210, 212, 216, and 218, are conventional slotted tubular members having threaded end connections suitable for use in an oil or gas well, an underground pipeline, or as a structural support. In several alternative embodiments, the slotted tubular members, 210, 212, 216, and 218 are conventional slotted tubular members for recovering or introducing fluidic materials such as, for example, oil, gas and/or water from or into a subterranean formation.
[0103] In an exemplary embodiment, as illustrated in FIG. 2a,the system 200 is initially positioned in a borehole 224 formed in a subterranean formation 226 that includes a water zone 226aand a targeted oil sand zone 226b. The borehole 224 may be positioned in any orientation from vertical to horizontal. In an exemplary embodiment, the upper end of the tubular support member 202 may be supported in a conventional manner using, for example, a slip joint, or equivalent device in order to permit upward movement of the tubular support member and tubular expansion cone 204 relative to one or more of the expandable tubular members, 206, 214, and 220, and tubular members, 210, 212, 216, and 218.
[0104] In an exemplary embodiment, as illustrated in FIG. 2b,a fluidic material 228 is then injected into the system 200, through the passages, 202aand 204a, of the tubular support member 202 and tubular expansion cone 204, respectively.
[0105] In an exemplary embodiment, as illustrated in FIG. 2c, the continued injection of the fluidic material 228 through the passages, 202aand 204a, of the tubular support member 202 and the tubular expansion cone 204, respectively, pressurizes the passage 18bof the shoe 18 below the tubular expansion cone thereby radially expanding and plastically deforming the expandable tubular member 206 off of the tapered external surface 204bof the tubular expansion cone 204. In particular, the intermediate non pre-expanded portion 206cof the expandable tubular member 206 is radially expanded and plastically deformed off of the tapered external surface 204bof the tubular expansion cone 204. As a result, the sealing member 206eengages the interior surface of the wellbore casing 104. Consequently, the radially expanded intermediate portion 206cof the expandable tubular member 206 is thereby coupled to the wellbore casing 104. In an exemplary embodiment, the radially expanded intermediate portion 206cof the expandable tubular member 206 is also thereby anchored to the wellbore casing 104.
[0106] In an exemplary embodiment, as illustrated in FIG. 2d, after the expandable tubular member 206 has been plastically deformed and radially expanded off of the tapered external surface 204bof the tubular expansion cone 204, the tubular expansion cone is pulled out of the borehole 224 by applying an upward force to the tubular support member 202. As a result, the second and third expandable tubular members, 214 and 220, are radially expanded and plastically deformed off of the tapered external surface 204bof the tubular expansion cone 204. In particular, the intermediate non pre-expanded portion 214cof the second expandable tubular member 214 is radially expanded and plastically deformed off of the tapered external surface 204bof the tubular expansion cone 204. As a result, the sealing member 214eengages the interior surface of the wellbore 224. Consequently, the radially expanded intermediate portion 214cof the second expandable tubular member 214 is thereby coupled to the wellbore 224. In an exemplary embodiment, the radially expanded intermediate portion 214cof the second expandable tubular member 214 is also thereby anchored to the wellbore 104. Furthermore, the continued application of the upward force to the tubular member 202 will then displace the tubular expansion cone 204 upwardly into engagement with the pre-expanded end 220aof the third expandable tubular member 220. Finally, the continued application of the upward force to the tubular member 202 will then radially expand and plastically deform the third expandable tubular member 220 off of the tapered external surface 204bof the tubular expansion cone 204. In particular, the intermediate non pre-expanded portion 220cof the third expandable tubular member 220 is radially expanded and plastically deformed off of the tapered external surface 204bof the tubular expansion cone 204. As a result, the sealing member 220eengages the interior surface of the wellbore 224. Consequently, the radially expanded intermediate portion 220cof the third expandable tubular member 220 is thereby coupled to the wellbore 224. In an exemplary embodiment, the radially expanded intermediate portion 220cof the third expandable tubular member 220 is also thereby anchored to the wellbore 224. As a result, the water zone 226aand fluidicly isolated from the targeted oil sand zone 226b.
[0107] After completing the radial expansion and plastic deformation of the third expandable tubular member 220, the tubular support member 202 and the tubular expansion cone 204 are removed from the wellbore 224.
[0108] Thus, during the operation of the system 10, the intermediate non pre-expanded portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, respectively, are radially expanded and plastically deformed by the upward displacement of the tubular expansion cone 204. As a result, the sealing members, 206e, 214e, and 220e, are displaced in the radial direction into engagement with the wellbore 224 thereby coupling the shoe 208, the expandable tubular member 206, the slotted tubular members, 210 and 212, the expandable tubular member 214, the slotted tubular members, 216 and 218, and the expandable tubular member 220 to the wellbore. Furthermore, as a result, the connections between the expandable tubular members, 206, 214, and 220, the shoe 208, and the slotted tubular members, 210, 212, 216, and 218, do not have to be expandable connections thereby providing significant cost savings. In addition, the inside diameters of the expandable tubular members, 206, 214, and 220, and the slotted tubular members, 210, 212, 216, and 218, after the radial expansion process, are substantially equal. In this manner, additional conventional tools and other conventional equipment may be easily positioned within, and moved through, the expandable and slotted tubular members. In several alternative embodiments, the conventional tools and equipment include conventional valving and other conventional flow control devices for controlling the flow of fluidic materials within and between the expandable tubular members, 206, 214, and 220, and the slotted tubular members, 210, 212, 216, and 218.
[0109] Furthermore, in the system 200, the slotted tubular members 210, 212, 216, and 218 are interleaved among the expandable tubular members, 206, 214, and 220. As a result, because only the intermediate non pre-expanded portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, respectively, are radially expanded and plastically deformed, the slotted tubular members, 210, 212, 216, and 218 can be conventional slotted tubular members thereby significantly reducing the cost and complexity of the system 10. Moreover, because only the intermediate non pre-expanded portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, respectively, are radially expanded and plastically deformed, the number and length of the interleaved slotted tubular members, 210, 212, 216, and 218 can be much greater than the number and length of the expandable tubular members. In an exemplary embodiment, the total length of the intermediate non pre-expanded portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, is approximately 200 feet, and the total length of the slotted tubular members, 210, 212, 216, and 218, is approximately 3800 feet. Consequently, in an exemplary embodiment, a system 200 having a total length of approximately 4000 feet is coupled to the wellbore 224 by radially expanding and plastically deforming a total length of only approximately 200 feet.
[0110] Furthermore, the sealing members 206e, 214e, and 220e, of the expandable tubular members, 206, 214, and 220, respectively, are used to couple the expandable tubular members and the slotted tubular members, 210, 212, 216, and 218 to the wellbore 224, the radial gap between the slotted tubular members, the expandable tubular members, and the wellbore 224 may be large enough to effectively eliminate the possibility of damage to the expandable tubular members and slotted tubular members during the placement of the system 200 within the wellbore.
[0111] In an exemplary embodiment, the pre-expanded ends, 206a, 206d, 214a, 214d, 220a, and 220d, of the expandable tubular members, 206, 214, and 220, respectively, and the slotted tubular members, 210, 212, 216, and 218, have outside diameters and wall thicknesses of 8.375 inches and 0.350 inches, respectively; prior to the radial expansion, the intermediate non pre-expanded portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, respectively, have outside diameters of 7.625 inches; the slotted tubular members, 210, 212, 216, and 218, have inside diameters of 7.675 inches; after the radial expansion, the inside diameters of the intermediate portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, are equal to 7.675 inches; and the wellbore 224 has an inside diameter of 8.755 inches.
[0112] In an exemplary embodiment, the pre-expanded ends, 206a, 206d, 214a, 214d, 220a, and 220d, of the expandable tubular members, 206, 214, and 220, respectively, and the slotted tubular members, 210, 212, 216, and 218, have outside diameters and wall thicknesses of 4.500 inches and 0.250 inches, respectively; prior to the radial expansion, the intermediate non pre-expanded portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, respectively, have outside diameters of 4.000 inches; the slotted tubular members, 210, 212, 216, and 218, have inside diameters of 4.000 inches; after the radial expansion, the inside diameters of the intermediate portions, 206c, 214c, and 220c, of the expandable tubular members, 206, 214, and 220, are equal to 4.000 inches; and the wellbore 224 has an inside diameter of 4.892 inches.
[0113] In an exemplary embodiment, the system 200 is used to inject or extract fluidic materials such as, for example, oil, gas, and/or water into or from the subterranean formation 226b.
[0114] Referring now to FIG. 3, an exemplary embodiment of an expandable tubular member 300 will now be described. The tubular member 300 defines an interior region 300aand includes a first end 300bincluding a first threaded connection 300ba, a first tapered portion 300c, an intermediate portion 300d, a second tapered portion 300e, and a second end 300fincluding a second threaded connection 300fa. The tubular member 300 further preferably includes an intermediate sealing member 300gthat is coupled to the exterior surface of the intermediate portion 300d.
[0115] In an exemplary embodiment, the tubular member 300 has a substantially annular cross section. The tubular member 300 may be fabricated from any number of conventional commercially available materials such as, for example, Oilfield Country Tubular Goods (OCTG), 13 chromium steel tubing/casing, or L83, J55, or P110 API casing.
[0116] In an exemplary embodiment, the interior 300aof the tubular member 300 has a substantially circular cross section. Furthermore, in an exemplary embodiment, the interior region 300aof the tubular member includes a first inside diameter D1, an intermediate inside diameter DINT, and a second inside diameter D2. In an exemplary embodiment, the first and second inside diameters, D1and D2, are substantially equal. In an exemplary embodiment, the first and second inside diameters, D1and D2, are greater than the intermediate inside diameter DINT.
[0117] The first end 300bof the tubular member 300 is coupled to the intermediate portion 300dby the first tapered portion 300c, and the second end 300fof the tubular member is coupled to the intermediate portion by the second tapered portion 300e. In an exemplary embodiment, the outside diameters of the first and second ends, 300band 300f, of the tubular member 300 is greater than the outside diameter of the intermediate portion 300dof the tubular member. The first and second ends, 300band 300f, of the tubular member 300 include wall thicknesses, t1and t2, respectively. In an exemplary embodiment, the outside diameter of the intermediate portion 300dof the tubular member 300 ranges from about 75% to 98% of the outside diameters of the first and second ends, 300aand 300f. The intermediate portion 300dof the tubular member 300 includes a wall thickness tINT.
[0118] In an exemplary embodiment, the wall thicknesses t1and t2are substantially equal in order to provide substantially equal burst strength for the first and second ends, 300aand 300f, of the tubular member 300. In an exemplary embodiment, the wall thicknesses, t1and t2, are both greater than the wall thickness tINTin order to optimally match the burst strength of the first and second ends, 300aand 300f, of the tubular member 300 with the intermediate portion 300dof the tubular member 300.
[0119] In an exemplary embodiment, the first and second tapered portions, 300cand 300e, are inclined at an angle, α, relative to the longitudinal direction ranging from about 0 to 30 degrees in order to optimally facilitate the radial expansion of the tubular member 300. In an exemplary embodiment, the first and second tapered portions, 300cand 300e, provide a smooth transition between the first and second ends, 300aand 300f, and the intermediate portion 300d, of the tubular member 300 in order to minimize stress concentrations.
[0120] The intermediate sealing member 300gis coupled to the outer surface of the intermediate portion 300dof the tubular member 300. In an exemplary embodiment, the intermediate sealing member 300gseals the interface between the intermediate portion 300dof the tubular member 300 and the interior surface of a wellbore casing 305, or other preexisting structure, after the radial expansion and plastic deformation of the intermediate portion 300dof the tubular member 300. In an exemplary embodiment, the intermediate sealing member 300ghas a substantially annular cross section. In an exemplary embodiment, the outside diameter of the intermediate sealing member 300gis selected to be less than the outside diameters of the first and second ends, 300aand 300f, of the tubular member 300 in order to optimally protect the intermediate sealing member 300gduring placement of the tubular member 300 within the wellbore casings 305. The intermediate sealing member 300gmay be fabricated from any number of conventional commercially available materials such as, for example, thermoset or thermoplastic polymers. In an exemplary embodiment, the intermediate sealing member 300gis fabricated from thermoset polymers in order to optimally seal the radially expanded intermediate portion 300dof the tubular member 300 with the wellbore casing 305. In several alternative embodiments, the sealing member 300gincludes one or more rigid anchors for engaging the wellbore casing 305 to thereby anchor the radially expanded and plastically deformed intermediate portion 300dof the tubular member 300 to the wellbore casing.
[0121] Referring to FIGS. 4, and 5ato 5d, in an exemplary embodiment, the tubular member 300 is formed by a process 400 that includes the steps of: (1) upsetting both ends of a tubular member in step 405; (2) expanding both upset ends of the tubular member in step 410; (3) stress relieving both expanded upset ends of the tubular member in step 415; (4) forming threaded connections in both expanded upset ends of the tubular member in step 420; and (5) putting a sealing material on the outside diameter of the non-expanded intermediate portion of the tubular member in step 425.
[0122] As illustrated in FIG. 5a, in step 405, both ends, 500aand 500b, of a tubular member 500 are upset using conventional upsetting methods. The upset ends, 500aand 500b, of the tubular member 500 include the wall thicknesses t1and t2. The intermediate portion 500cof the tubular member 500 includes the wall thickness tINTand the interior diameter DINT. In an exemplary embodiment, the wall thicknesses t1and t2are substantially equal in order to provide burst strength that is substantially equal along the entire length of the tubular member 500. In an exemplary embodiment, the wall thicknesses t1and t2are both greater than the wall thickness tINTin order to provide burst strength that is substantially equal along the entire length of the tubular member 500, and also to optimally facilitate the formation of threaded connections in the first and second ends, 500aand 500b.
[0123] As illustrated in FIG. 5b, in steps 410 and 415, both ends, 500aand 500b, of the tubular member 500 are radially expanded using conventional radial expansion methods, and then both ends, 500aand 500b, of the tubular member are stress relieved. The radially expanded ends, 500aand 500b, of the tubular member 500 include the interior diameters D1and D2. In an exemplary embodiment, the interior diameters D1and D2are substantially equal in order to provide a burst strength that is substantially equal. In an exemplary embodiment, the ratio of the interior diameters D1and D2to the interior diameter DINTranges from about 100% to 120% in order to facilitate the subsequent radial expansion of the tubular member 500.
[0124] In a preferred embodiment, the relationship between the wall thicknesses t1, t2, and tINTof the tubular member 500; the inside diameters D1, D2and DINTof the tubular member 500; the inside diameter Dwellboreof the wellbore casing, or other structure, that the tubular member 500 will be inserted into; and the outside diameter Dconeof the expansion cone that will be used to radially expand the tubular member 500 within the wellbore casing is given by the following expression:
[0125] where t1=t2; and
[0126] D1=D2.
[0127] By satisfying the relationship given in equation (1), the expansion forces placed upon the tubular member 500 during the subsequent radial expansion process are substantially equalized. More generally, the relationship given in equation (1) may be used to calculate the optimal geometry for the tubular member 500 for subsequent radial expansion and plastic deformation of the tubular member 500 for fabricating and/or repairing a wellbore casing, a pipeline, or a structural support.
[0128] As illustrated in FIG. 5c, in step 420, conventional threaded connections, 500dand 500e, are formed in both expanded ends, 500aand 500b, of the tubular member 500. In an exemplary embodiment, the threaded connections, 500dand 500e, are provided using conventional processes for forming pin and box type threaded connections available from Atlas-Bradford.
[0129] As illustrated in FIG. 5d, in step 425, a sealing member 500fis then applied onto the outside diameter of the non-expanded intermediate portion 500cof the tubular member 500. The sealing member 500fmay be applied to the outside diameter of the non-expanded intermediate portion 500cof the tubular member 500 using any number of conventional commercially available methods. In a preferred embodiment, the sealing member 500fis applied to the outside diameter of the intermediate portion 500cof the tubular member 500 using commercially available chemical and temperature resistant adhesive bonding.
[0130] In an exemplary embodiment, the expandable tubular members, 206, 214, and 220, of the system 200 are substantially identical to, and/or incorporate one or more of the teachings of, the tubular members 300 and 500.
[0131] Referring to FIG. 6, an exemplary embodiment of tubular expansion cone 600 for radially expanding the tubular members 206, 214, 220, 300 and 500 will now be described. The expansion cone 600 defines a passage 600aand includes a front end 605, a rear end 610, and a radial expansion section 615.
[0132] In an exemplary embodiment, the radial expansion section 615 includes a first conical outer surface 620 and a second conical outer surface 625. The first conical outer surface 620 includes an angle of attack α1and the second conical outer surface 625 includes an angle of attack α2. In an exemplary embodiment, the angle of attack α1is greater than the angle of attack α2. In this manner, the first conical outer surface 620 optimally radially expands the intermediate portions, 206c, 214c, 220c, 300d, and 500c, of the tubular members, 206, 214, 220, 300, and 500, and the second conical outer surface 525 optimally radially expands the pre-expanded first and second ends, 206aand 206d, 214aand 214d, 220aand 220d, 300band 300f, and 500aand 500b, of the tubular members, 206, 214, 220, 300 and 500. In an exemplary embodiment, the first conical outer surface 620 includes an angle of attack α1ranging from about 8 to 20 degrees, and the second conical outer surface 625 includes an angle of attack α2ranging from about 4 to 15 degrees in order to optimally radially expand and plastically deform the tubular members, 206, 214, 220, 300 and 500. More generally, the expansion cone 600 may include 3 or more adjacent conical outer surfaces having angles of attack that decrease from the front end 605 of the expansion cone 600 to the rear end 610 of the expansion cone 600.
[0133] Referring to FIG. 7, another exemplary embodiment of a tubular expansion cone 700 defines a passage 700aand includes a front end 705, a rear end 710, and a radial expansion section 715. In an exemplary embodiment, the radial expansion section 715 includes an outer surface having a substantially parabolic outer profile thereby providing a paraboloid shape. In this manner, the outer surface of the radial expansion section 715 provides an angle of attack that constantly decreases from a maximum at the front end 705 of the expansion cone 700 to a minimum at the rear end 710 of the expansion cone. The parabolic outer profile of the outer surface of the radial expansion section 715 may be formed using a plurality of adjacent discrete conical sections and/or using a continuous curved surface. In this manner, the region of the outer surface of the radial expansion section 715 adjacent to the front end 705 of the expansion cone 700 may optimally radially expand the intermediate portions, 206c, 214c, 220c, 300d, and 500c, of the tubular members, 206, 214, 220, 300, and 500, while the region of the outer surface of the radial expansion section 715 adjacent to the rear end 710 of the expansion cone 700 may optimally radially expand the pre-expanded first and second ends, 206aand 206d, 214aand 214d, 220aand 220d, 300band 300f, and 500aand 500b, of the tubular members, 206, 214, 220, 300 and 500. In an exemplary embodiment, the parabolic profile of the outer surface of the radial expansion section 715 is selected to provide an angle of attack that ranges from about 8 to 20 degrees in the vicinity of the front end 705 of the expansion cone 700 and an angle of attack in the vicinity of the rear end 710 of the expansion cone 700 from about 4 to 15 degrees.
[0134] In an exemplary embodiment, the tubular expansion cone 204 of the system 200 is substantially identical to the expansion cones 600 or 700, and/or incorporates one or more of the teachings of the expansion cones 600 and/or 700.
[0135] In several alternative embodiments, the teachings of the apparatus 130, the system 200, the expandable tubular member 300, the method 400, and/or the expandable tubular member 500 are at least partially combined.
[0136] Referring to FIG. 8, in an alternative embodiment, conventional temperature, pressure, and flow sensors, 802, 804, and 806, respectively, are operably coupled to the perforated tubulars 145 of the apparatus 130. The temperature, pressure, and flow sensors, 802, 804, and 806, respectively, in turn are operably coupled to a controller 810 that receives and processes the output signals generated by the temperature, pressure, and flow sensors to thereby control the operation of the flow control valves 160 to enhance the operational efficiency of the apparatus 130. In several exemplary embodiments, the control algorithms utilized by the controller 810 for controlling the operation of the flow control valves 160 as a function of the operating temperature, pressure, and flow rates within the perforated tubular members 145 are conventional.

In this manner, the solid tubular member 905 fluidicly seals the radial passages formed in the perforated tubular member 145 thereby preventing the passage of fluidic materials and/or formation materials through the perforated tubular member.
[0138] Referring to FIG. 10, in an alternative embodiment, the radial openings in one of the perforated tubular members 145 are sealed by injecting a hardenable fluidic sealing material 1005 into the radial openings in the one perforated tubular member by positioning a closed ended pipe 1010 having one or more radial openings 1010awithin the one perforated tubular member 145. Conventional sealing members 1015 and 1020 then seal the interface between the pipe 1010 and the opposite ends of the one perforated tubular member 145. The hardenable fluidic sealing material 1005 is then injected into the radial openings in the one perforated tubular member 145. The sealing members 140 prevent the passage of the hardenable fluidic sealing material out of the annulus between the one perforated tubular member 145 and the formation 125. The pipe 1010 and sealing members, 1015 and 1020, are then removed from the apparatus 130, and the hardenable fluidic sealing material is allowed to cure. A conventional drill string may then be used to remove any excess cured sealing material from the interior surface of the one perforated tubular member 145. In an exemplary embodiment, the hardenable fluidic sealing material is a curable epoxy resin.
[0139] In an alternative embodiment, as illustrated in FIG. 11, one or more of the perforated tubular members 145 of the apparatus 130 are radially expanded and plastically deformed into contact with the surrounding formation 125 thereby compressing the surrounding formation. In this manner, the surrounding formation 125 is maintained in a state of compression thereby stabilizing the surrounding formation, reducing the flow of loose particles from the surrounding formation into the radial openings of the perforated tubular member 145, and enhancing the recovery of hydrocarbons from the surrounding formation.
[0140] In an alternative embodiment, a seismic source 1105 is positioned on a surface location to thereby impart seismic energy into the formation 125. In this manner, particles lodged in the radial openings in the perforated tubular member 145 may be dislodged from the radial openings thereby enhancing the subsequent recovery of hydrocarbons from the formation 125.
[0141] In an alternative embodiment, after the perforated tubular member 145 has been radially expanded and plastically formed into contact with the surrounding formation 125, thereby coupling the perforated tubular member 145 to the surrounding formation, an impulsive load is applied to the perforated tubular member. The impulsive load may be applied to the perforated tubular member 145 by applying the load to the end of the apparatus 130. The impulsive load is then transferred to the surrounding formation 125 thereby compacting and/or slurrifying the surrounding formation. As a result, the recovery of hydrocarbons from the formation 125 is enhanced.
[0142] In an alternative embodiment, as illustrated in FIG. 12, a wellbore casing 1205 having one or more perforations 1210 is positioned within the wellbore 105 that traverses the formation 125. When the apparatus 130 is positioned within the wellbore 105, one or more of the perforated tubular members 145 of the apparatus 130 are radially expanded and plastically deformed into contact with the wellbore casing 1205 thereby compressing the surrounding formation 125. In this manner, the surrounding formation 125 is maintained in a state of compression thereby stabilizing the surrounding formation, reducing the flow of loose particles from the surrounding formation into the radial openings of the perforated tubular member 145, and enhancing the recovery of hydrocarbons from the surrounding formation.
[0143] In an alternative embodiment, a seismic source 1215 is positioned on a surface location to thereby impart seismic energy into the formation 125. In this manner, particles lodged in the radial openings in the perforated tubular member 145 may be dislodged from the radial openings thereby enhancing the subsequent recovery of hydrocarbons from the formation 125.
[0144] In an alternative embodiment, after the perforated tubular member 145 has been radially expanded and plastically formed into contact with the wellbore casing 1205, thereby coupling the perforated tubular member 145 to the surrounding formation, an impulsive load is applied to the perforated tubular member. The impulsive load may be applied to the perforated tubular member 145 by applying the load to the end of the apparatus 130. The impulsive load is then transferred to the surrounding formation 125 thereby compacting and/or slurrifying the surrounding formation. As a result, the recovery of hydrocarbons from the formation 125 is enhanced.
