  • System and method of using a thermoplastic casing in a wellbore
    Patent number: 12286875
    Abstract: Systems and methods for using a continuous, thermoplastic tubing as a casing in a wellbore are provided. A continuous, thermoplastic tubing can be a high density polyethylene (HDPE) material that is stored in a coiled manner on a spindle. A screen can be attached to an end of the casing, and a tremie line can be selectively connected to the screen to inject gravel and cement downhole to pack the screen in place and grout the casing in place in the wellbore. The use of a continuous, thermoplastic tubing removes joints from the casing to improve performance, and such tubing is more readily available and cheaper than alternatives among other benefits described herein.
