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 ...

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 ...

Bradenhead cementing, where pressure is applied to the entire casing string, improves cementing operational efficiency and economic viability. It isolates the vertical part of the wellbore from ...

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 ...
