Overpressure is one of the most important factors for oil and gas charging in petroliferous basins. Research on overpressure evolution and its formation mechanisms is of great significance for ...

While every effort is put forth before drilling begins to ensure a successful well, not every well hits hydrocarbons at a commercially productive level. Statistically, wildcat (or exploratory) wells ...

The folks at TRW have come up with a revolutionary idea for reducing the piston ring drag of the top compression ring. It is called the Pressure Balance Ring (PBR). Essentially, the PBR design amounts ...

Formation testing is the downhole process of measuring in-situ reservoir pressure, estimating permeability/mobility, and capturing representative fluid samples before committing to completion and ...
