Reservoir Management & Improved Recovery

Reservoir management involves monitoring and adjusting production strategies to maintain pressure, optimize fluid flow, and extend field life. Improved recovery techniques such as water flooding, gas injection, and enhanced oil recovery increase the amount of extractable hydrocarbons.

  • Miscible Flooding
    5

    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
    7

    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
    10

    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)
    11

    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
    8

    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
    7

    Polymer flooding is a chemical enhanced oil recovery (EOR) method used to improve the efficiency of waterflooding in oil reservoirs. By adding small amounts of…

  • Porosity
    5

    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…

  • Possible reserve
    2

    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
    7

    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
    6

    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 reserve
    2

    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
    8

    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…
