This Notice to Lessees and Operators (NTL) supersedes NTL No. 98-28, dated December 1, 1998. It provides the new drilling window schedule and updates regulatory citations. Drilling Window Program The Gulf of Mexico OCS Region (GOMR), after consultation with the U.S. Air Force, established a drilling window program in 1991 for exploratory activities on oil and gas leases that were obtained through Lease Sales Nos. 79, 94, and 116 and that contain Lease Stipulation No. 5. In accordance with this lease stipulation, the drilling window program ensures that exploration activities can be conducted predictably, orderly, and safely without interfering with scheduled military activities or jeopardizing the national defense mission.
Recently, an incident occurred on a drillship that had the potential for causing a serious well control event. An employee was attempting to conduct a function test of the blind-shear rams. However, he inadvertently pushed the lower marine riser package (LMRP) button instead of the blind-shear ram button on the control panel. Since the LMRP button was not part of the primary or emergency disconnect sequence, the pod stabs did not retract and the blind-shear rams did not close. The disconnect allowed the release of drilling mud from the riser. Fortunately, the wellbore was cased, and a well control event caused by a loss of riser hydrostatics did not occur.
According to 30 CFR 250.301(a), you must inspect production facilities daily or at intervals approved or prescribed by the District Supervisor to determine if pollution is occurring. Under this authority, the appropriate Gulf of Mexico OCS Region (GOMR) District Supervisor will use the following matrix and evaluation code to determine the pollution inspection interval for an individual unmanned facility:
