A leading onshore natural gas producer working Northern Louisiana experienced problems along the vertical section of a horizontal development well.

Enventure deployed two ESeal Liners enabling them to continue the planned completion.

A major operator was sidetracking out of an existing well to a nearby reservoir.The first attempt to sidetrack utilizing a conventional casing design failed to reach the target depth and damaged the 13-3/8 in. casing.

The casing design for a...
