In the normal well operating process, the oil and casing pressures of the wellhead are stable.
At the same time, the oil and casing pressures and temperature of the wellhead can be recorded.
If stand pipe pressure decreases as the casing pressure increases, or both pressures fluctuate evidently, it suggests a gas zone is encountered in drilling.
(iii) the increase of casing pressure coupled with decreasing stand pipe pressure,
The data monitoring system provided the real-time data required such as casing pressure
, injection and outlet gas rates, injection and outlet drilling fluid density, and injection drilling fluid rates, when performing reservoir characterization for every zone.
