dual-porosity reservoir
Oil & gas; Oilfield
A rock characterized by primary porosity from original deposition and secondary porosity from some other mechanism, and in which all flow to the well effectively occurs in one ...
porous medium
Oil & gas; Oilfield
A rock or soil with interconnected pores that permit flow of fluids through the medium.
source rock
Oil & gas; Oilfield
A rock rich in organic matter which, if heated sufficiently, will generate oil or gas. Typical source rocks, usually shales or limestones, contain about 1% organic matter and at ...
pressure buildup
Oil & gas; Oilfield
A rise in well pressure as a function of time observed after a well is shut in or after the production rate is reduced. Buildup pressures are normally measured at or near the ...
array propagation resistivity
Oil & gas; Oilfield
A resistivity recorded by a measurements-while-drilling propagation tool consisting of an array of transmitters and receivers whose signals are recorded separately and combined by ...
waterdrive
Oil & gas; Oilfield
A reservoir-drive mechanism whereby the oil is driven through the reservoir by an active aquifer. As the reservoir depletes, the water moving in from the aquifer below displaces ...
infinite-acting reservoir
Oil & gas; Oilfield
A reservoir with no apparent outer boundary limit affecting fluid flow during a test period. Unless an outer boundary is close to the wellbore, such as a nearby fault, it usually ...
