Integrity eXplorer Service Performed Industry’s First Wireline Cement Evaluation Logging in Air-filled Borehole

Location: Northern U.S.

Operators in the Northern U.S. store natural gas for future use in underground gas storage (UGS) wells. Evaluating the casing cement for zonal isolation in these wells has proved to be costly because of the time and resource-intensive nature of the operation.

Conventional cement evaluation services require operators to relieve stored gas pressure, kill the well, and fill the wellbore with liquid to get effective cement evaluation data. In order to minimize losses, operators wait until the well pressure is lower than the well discovery pressure, but this condition typically occurs only once a year, significantly limiting the time when cement evaluation in these wells is possible. To reduce operational cost, safety, and environmental implications, operators need the ability to log these UGS wells at any time.
