Alternatively, the production history can be fitted to a curve to estimate future oil production (decline curve method). [2] The analogous term original gas-in-place (OGIP) is used to refer to the total natural gas in a reservoir. Furthermore, there is a term called Hydrocarbons Initially in Place (HCIIP) that is used for either oil or gas ...
Stack Tank Oil (STO) density (or API) may also be used by regulatory bodies to classify oil and oil products. Other properties such as Molecular Weight , saturated aromatic resin and asphaltene (SARA), refractive index , wax appearance temperature, asphaltene precipitation, and acid number , are also specified at Stock Tank conditions.

Gas initially in place (GIIP) or original gas in place (OGIP) denote the total estimated quantity (volume) of natural gas contained in a "subsurface" asset prior to extraction . [ 1 ] Gas Initially In Place = Gross Rock Volume * Net/Gross * Porosity * average initial Gas Saturation / Formation Volume Factor [ 2 ]
Such oil is called the stock tank oil initially in place. As a result of studying factors such as the permeability of the rock (how easily fluids can flow through the rock) and possible drive mechanisms, it is possible to estimate the recovery factor, or what proportion of oil in place can be reasonably expected to be produced.
Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations.The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
Affordability is becoming a growing challenge for younger generations. Although they're often drawn to vibrant cities for their career opportunities and lifestyle perks, high housing costs make ...
A comprehensive list of discriminatory acts against American Muslims might be impossible, but The Huffington Post wants to document this deplorable wave of hate using news reports and firsthand accounts.
The total estimated quantity (volumes) of oil and/or gas contained in a subsurface reservoir, is called oil or gas initially in place (STOIIP or GIIP respectively). [12] However, only a fraction of in place oil & gas can be brought to the surface ( recoverable ), [ q ] and it is only this producible fraction that is considered to be either ...
