Reservoir Management & Improved Recovery

Miscible flooding is a tertiary oil recovery (enhanced oil recovery, EOR) method in which a fluid (gas or liquid) is injected into a petroleum reservoir…

Mobility ratio is a dimensionless parameter used in reservoir engineering to describe the ease with which one fluid can move through a porous medium compared…

Net Pay refers to the portion of a hydrocarbon-bearing reservoir that contains sufficient oil or gas in economically viable quantities to justify production. It is…

Oil in Place (OIP) is the total volume of crude oil that is estimated to be contained within a natural underground reservoir before any production…

Permeability is a fundamental rock property that quantifies a reservoir’s ability to transmit fluids (oil, gas, or water) through its pore network. It directly governs…

Polymer flooding is a chemical enhanced oil recovery method that thickens injection water with a water-soluble polymer to improve the efficiency of a waterflood. Raising…

Porosity is a fundamental rock property that measures the void spaces within a reservoir rock, expressed as a percentage of the total rock volume. These…

In the oil and gas industry, a possible reserve is a category of hydrocarbon reserves that has a lower probability of commercial recovery than probable…

Pressure Transient Analysis (PTA) is a powerful, quantitative interpretation technique used in reservoir engineering to evaluate well and reservoir properties by analyzing the pressure response…

Primary recovery refers to the initial stage of hydrocarbon production from a reservoir, where oil or gas flows to the surface naturally or with minimal…

Probable reserves are those unproved reserves which analysis of geological and engineering data suggests are more likely than not to be recoverable. In the standardized…

Production Logging (PL) is a suite of downhole diagnostic techniques used to evaluate the dynamic behavior of a well during production or injection. By running…
