  2. Petroleum geology - Wikipedia

    en.wikipedia.org/wiki/Petroleum_geology

    The net-to-gross ratio, typically estimated from analogues and wireline logs, is used to calculate the proportion of the sedimentary packages that contains reservoir rocks. The bulk rock volume multiplied by the net-to-gross ratio gives the net rock volume of the reservoir.

  3. Pay (geology) - Wikipedia

    en.wikipedia.org/wiki/Pay_(geology)

    Pay (geology) Pay is an expression used in hydrocarbon mining. It denotes a portion of a reservoir that contains economically recoverable hydrocarbons. The term derives from the possibility of "paying" an income surpassing the costs. Equivalent terms are pay sand or pay zone. Overall interval in which pay volumes occur is the gross pay; smaller ...

    en.wikipedia.org/wiki/Hydrocarbon_exploration

    Net reserve Part of net sand that has the minimum reservoir qualities; i.e. minimum porosity and permeability values. [5] Net/gross ratio (N/G) Proportion of the GRV formed by the reservoir rock (range is 0 to 1) Porosity Percentage of the net reservoir rock occupied by pores (typically 5-35%) Hydrocarbon saturation (Sh)

  5. Gross Reservoir - Wikipedia

    en.wikipedia.org/wiki/Gross_Reservoir

    Gross Reservoir, located in Boulder County, Colorado, is owned and operated by Denver Water. Completed in 1954, the reservoir has a surface area of 440 acres (180 ha), and the spillway sits at 7,225 feet (2,202 m) elevation. [1] The reservoir is undergoing an expansion project. The reservoir receives water from South Boulder Creek and the ...

  6. Oil and gas reserves and resource quantification - Wikipedia

    en.wikipedia.org/wiki/Oil_and_gas_reserves_and...

    Reservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids (typically, oil, water, and gas) through porous media. The amount of oil & gas recoverable from a conventional reservoir is assessed by accurately characterising the static recoverable volumes and history matching that to ...

  7. Bentley Oil Field - Wikipedia

    en.wikipedia.org/wiki/Bentley_Oil_Field

    The reservoir is high porosity (33%), net to gross pay (90%) and with ultra-high apparent horizontal permeabilities approaching 50 Darcies based on flow-test measurements, but consistent with unconsolidated sand. Appraisal History

  8. Proven reserves - Wikipedia

    en.wikipedia.org/wiki/Proven_reserves

    Proven reserves. Proven reserves (also called measured reserves, 1P, and reserves) is a measure of fossil fuel energy reserves, such as oil and gas reserves and coal reserves. It is defined as the " [q]uantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well ...

    The term “net carbs” simply refers to carbs that are absorbed by the body. To calculate the net carbs in whole foods, subtract the fiber from the total number of carbs. To calculate the net ...
