Abstract
A casing pipe assembly can include a first casing pipe having a top coupling member and a pipe curvature, where the top coupling member has first threads in a first direction, and where the pipe curvature substantially corresponds to a wellbore curvature. The casing pipe assembly can also include a second casing pipe having a bottom coupling member and substantially the same pipe curvature, where the bottom coupling member has second threads in a second direction. The casing pipe assembly can further include a coupling device having a bottom coupling member and a top coupling member, where the bottom coupling member has third threads in the first direction that threadably couple to the first threads of the first casing pipe, and where the top coupling member has fourth threads in the second direction that threadably couple to the second threads of the second casing pipe.
