31 May 2016 There should be at least a 50% probability (P50) that the quantities Modernization of oil and gas reporting, revisions and additions to the A given case might give a P90 oil recovery and a P10 gas recovery. In general there will be no realization that gives P90 results for more than one variable. Abstract As a result of improved technology and declining conventional gas reserves, reservoirs have emerged as significant sources of oil and natural gas . This technique will be discussed in detail and a sample case will be given to To maintain consistency, the same class confidence hurdles (P90/P50/P10) short duration drawdowns and capture fluid/gas samples (wireline formation tests )

For discovered and commercial volume estimates, the discrete (incremental) volumes within these bounds are generally referred to as proved, quantities of oil and gas, both discovered and undiscovered, associated with reservoirs, on resource development to manage energy supply. In the case of Norway, the
This paper discusses a new tool that was developed specifically for generating probabilistic (P10, P50 and P90)1 type curves for shale plays, based on a series of input production wells, which can be used in the early stages of the stochastic analysis of shale gas prospects. The EV/EBITDA ratio compares the oil and gas business, free of debt, to EBITDA. This is an important metric as oil and gas firms typically have a great deal of debt and the EV includes the cost of paying it off. EBITDA measures profits before interest. Case Energy Partners and affiliates (Case) is a leading purchaser of oil and gas mineral rights and royalty interests throughout the United States. Case specializes in providing a simple and quick way for individuals, trusts, partnerships, and companies to quickly liquidate their oil and gas holdings for maximum value. To assess the solar resource or energy yield potential of a site, we model the solar resource/energy yield using best available information and methods. The resulting estimate is the P50 estimate, or in other words, the “best estimate”. P50 is essentially a statistical level of confidence suggesting that we expect to exceed the predicted solar resource/energy yield 50% of the time. However Subsequently, an exploration review was carried out on this database and the reviewers discovered inconsistencies in the volume estimates: ranges were not wide enough, the best (P50) EUR was bigger than the high (P10) EUR and the best (P50) EUR was smaller than the low (P90) EUR in some prospects Fig 1. The reservoir engineer was not involved in this review, and it took several days and lots of rework to discover the root cause of the inconsistent EUR volume estimate, which was, of course We initially adopted our oil and gas disclosure requirements in 1978 and 1982.9 Since that time, there have been significant changes in the oil and gas industry and markets, including technological advances, and changes in the types of projects in which oil and gas companies invest their capital.10 Prior to our issuance of the Concept Release 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 and was approved by the three organizations in February 2000.

An example of its use in the oil and gas industry is the estimation of potential lifecycle (i.e. a feasible representation of the life of the asset) to predict asset performance. Sometimes, when running models with a large variation, analysts will engage simulations that go beyond 1000 lifecycles. In this case, the mode, mean and P50 would Cumulative probabilities: P10 P50 P90. A given case might give a P90 oil recovery and a P10 gas recovery. In general there will be no realization that gives P90 results for more than one variable. P50 is defined as 50% of estimates exceed the P50 estimate (and by definition, 50% of estimates are less than the P50 estimate). It is a good middle estimate. Mean and Expected (same level of measure just different names) usually lie about the P40-P30 levels in oil field evaluations and are therefore high estimates. Oil & Gas Consultants International Aurora, Colo. the confidence levels are P50 for "proved + probable" reserves and P10 for "proved + probable + possible" reserves. The base case is for 5 Common Trading Multiples Used in Oil and Gas Valuation Probable reserves are referred to as P50 or having a 50% certainty of being produced. When used in conjunction with one another, they P50 and P10 respectively. For discovered and commercial volume estimates, the discrete (incremental) volumes within these bounds are generally referred to as proved, quantities of oil and gas, both discovered and undiscovered, associated with reservoirs, on resource development to manage energy supply. In the case of Norway, the Low (P90)/high (P10) range. It is customary in the industry to describe this uncertainty in terms of a low (P90)/high (P10) range. This is consistent with both the Petroleum Resource Management System (PRMS) and the Securities and Exchange Commission (SEC) .Both define the reserves and resources estimates in terms of P90/P50/P10 ranges :.
