The Bureau of Safety and Environmental Enforcement (BSEE) released a technical review following an underground loss of well control that resulted in gas flow into a shallow sand reservoir. The technical review, "Evaluation of Seal Assembly & Cement Failures," was completed by the BSEE's Quality Control-Failure Incident Team (QC-FIT) and submitted to BSEE Director Brian Salerno.

BSEE will continue to monitor information related to the performance of dual barrier systems, and will update this technical review as new information becomes available.
