... additional solution in resolving high demands of energy. However, existing hazards on such well may deteriorates spending and risk of safety of operation should the method remain conventional. Underground blow outs, total loss circulation, hole breathing, and gas migration are some of unconventional...

... and assuming no gas migration, the influx pressure at the initial time of the circulation is equal to formation PP + APL. Thus Ptd in Eq. (3) is formation PP which, for KT calculations, should be considered at its maximum expected level as the worst case scenario. Eq. (3) and Eq. (5) change to Eq. (6...

... obtained from one well to the other. First, a gas migration prediction software is utilized to predict gas migration and its severity. Then, depending on the severity and other well conditions, the type of gas migration additive and the additive concentration is selected and tested in the laboratory...

... Abstract Gas migration during primary cementing has been the subject of numerous studies and is well documented in referenced literature. Methodologies to predict gas flow potential have been devised and various systems have been offered to prevent the phenomenon. However, high cost associated...
