Problems solved by technology

[0063] There is a need for increased recovery of fluids within subterranean deposits and the use of fewer main boreholes penetrating through the groundwater formation, which cannot be achieved by utilizing conventional single concentric bore well designs due to the increased recovery rate Typically requires additional wells or penetration through groundwater formations and cap rocks containing toxic fluids, thereby increasing the risk of leakage into said groundwater formations

Embodiment Construction

[0136] Before describing in detail selected embodiments of the invention, it is to be understood that the invention is not limited to the specific embodiments described herein, but that the invention can be practiced or carried out in various ways.

[0137] now refer to figure 1 , 2 . The arrangement of the prior art coiled pipe drilling (51B) rig (51), the wireline drilling (51D) rig (51) above the line A3-A3 and the prior art offshore drilling above the line A4-A4 Schematic illustration of a cross-sectional portion of a spud drilling (51C) drill frame (51) through the environment and subterranean formations. About attached Figure 1-4 , any drilling frame including the described drilling frame (51) can be used to operate and / or drill within the large diameter high pressure piping system (1); however, the larger lifting capacity drilling frames (51A and 51C) It is generally preferred for installing said piping system (1), especially when these drill stands are suitable f...

Abstract

Well conduit system and methods using a first outer conduit wall and at least one second inner conduit wall positioned through a wellhead to define an annulus with radial loading surfaces extending across the annulus and radially between at least two of the conduit walls to form passageways through subterranean strata concentrically, wherein an inner pipe body of greater outer diameter is inserted into an outer pipe body of lesser inner diameter by elastically expanding the circumference of the outer pipe body and elastically compressing the circumference of the inner pipe body, using a hoop force exerted therebetween. Releasing the hoop force after insertion will release the elastic expansion and compression of the pipe bodies to abut the radial loading surfaces within the annulus for sharing elastic hoop stress resistance and thereby forming a greater effective wall thickness, capable of containing higher pressures than the conduit walls could otherwise bear.
