Novel Liner System Improves Coring Performance, Rig Safety, and Wellsite Core Procesing

摘要

A one-piece aluminum inner barrel liner system has been employed to protect and containerize core material during coring operations with conventional and wireline core barrels. The system offered enhanced safety features and improved core handling on the rig floor. The integral one-piece liners securely containerized the core during acquisition. Vent holes allowed expelled gas to escape during recovery to the surface, improving safety during core retrieval and handling. The companion Non-Rotating Inner Tube Stabilizer system will ease separation of the 30-foot liner joints, thus improving wellsite handling procedures and safety during extended core runs. The design allowed the liners to be opened quickly and easily at the surface for rapid examination and sub-sampling of the core material.
