Abstract
One of the significant hazards, which can potentially “kill” a well during the drilling process, is the presence of gas pockets or gas accumulations. Gas changing from solution phase to free phase has a substantial energy. Overpressure, created by gas, can easily block the drilling bit and destroy the borehole. On the other hand, the gas itself is very dangerous for platform personnel and for the environment. Sulfur gas and carbon dioxide in high concentration can poison people, and hydrocarbon gases, while not so toxic, can flame.
