Such as in the oil and gas reserves disclosure

Natural gas that is in solution with crude oil in the reservoir

A DST is used to obtain reservoir fluid samples, static bottomhole pressure measurements, indications of productivity and short-term flow and pressure buildup tests to estimate permeability and damage extent. DSTs are performed in the open hole

A logging method that records deviation from the vertical

Located down the slope of a dipping plane or surface. In a dipping (not flat-lying) hydrocarbon reservoir that contains gas, oil and water, the gas is updip, the gas-oil contact is downdip from the gas and the oil-water contact is still further downdip

A petroleum reservoir whose existence has been determined by the drilling of a well. Petroleum quantities that are discovered are “known accumulations” or “known reservoirs”.

The movement of molecules from area of high concentration to low concentration within a solution

A source of natural reservoir energy in which the dissolved gas coming out of the oil expands to force the oil into the wellbore

As the hole of the well gets deeper, pipe is added to the drill bit to allow it to dig further. These lengths of drill pipe form the drill string
