Depletion Method Overview Depletion is a periodic charge to expense for the use of natural resources . Thus, it is used in situations where a company has recorded an asset for such items as oil reserves, coal deposits, or gravel pits. The calculation of depletion involves these steps: Comput

23 Mar 2015 Estimation of Reserves • The amount of oil in a subsurface reservoir is called oil initial in place (OIIP) • There are a number of different methods of 1 Mar 2003 When calculated before oil extraction begins, these reserves are also called the ultimate reserves, because they represent the best estimate of 20 Aug 2012 reserves are usually defined as the proportion of resources, here oil and resulting from exploration campaign and geological calculations. 5 Jul 2016 How much oil lies beneath the desert sands of Saudi Arabia and how Because the calculation of reserves is deliberately conservative, it is 14 Feb 2019 My calculation of Saudi reserves based on Saudi production since the discovery of oil in 1938 till now (for which we have figures) and a Reserves definitions are based on sophisticated engineering estimate calculations set by two industry bodies: The Society of Petroleum Engineers (SPE ); The

reporting of petroleum reserves and resources on a worldwide basis In 1999, the SPE Oil and Gas Reserves Committee, in conjunction with WPC, undertook the development of a resource classification system that would include the 1997 reserves definitions. This effort was joined by the American Association of Petroleum Geologists (AAPG) later that year
