n pi: valve-controlled pipelines, fitted with pumps, which permit a vessel to take on seawater for ballasting into any of the vessels tanks.

n pi: the final testing of a ship or offshore drilling vessel before it is put to work.

n: The water-based drilling fluid be made up of natural or artificial sea water.

n: (SBGD) special diverter designed to handle shallow gas kicks that occur offshore. Unlike a normal diveIter that the gas from the kick releases at d1e surface, an SBGD allows the gas to be released from the wellhead on the seafloor. Thus, the gas bypasses the rig. See diverter.

n: the penetration of a drilling fluid into a potentially productive formation, thus restricting or preventing the formation from producing.

a rock seal that is sufficiently impermeable to prevent leakage of hydrocarbons from a trap.

a elastomer or metal-to-metal device that isolates one pressure region from another.
