Probable additional reserves are attributed to known accumulations and the probabilistic, cumulative sum of proven and probable reserves (with a probability of P50), also referred to in the industry as "2P" (Proven plus Probable) [13] The P50 designation means that there should be at least a 50% chance that the actual volumes recovered will be ...
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 "quantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well established or known ...
2P – proved and probable reserves; 3C – three components seismic acquisition (x, y, and z) 3C – Proved, probable and possible contingent resources; 3D – three-dimensional ; 3P – proved, probable and possible reserves; 4D – multiple 3Ds acquired over time (the 4th D) over the same area with the same parameters
Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop. In this way, Canada's proven reserves increased suddenly in 2003 when the oil sands of Alberta were seen to
The licence area covers 498 km 2 with gross lease 2P Reserves of 71.5 million barrels (11.4 million cubic metres), [10] gross lease 3P Reserves of 117 million bbl (18.6 million m 3), and gross lease 2C Contingent Resources of 15.5 million bbl (2.46 million m 3), as estimated by McDaniel. [11]
Nearly 40% of oil, gas and coal from existing and approved sites will need to stay in the ground to avoid dangerous warming, research says.
Mineral Reserves are subdivided in order of increasing confidence into Probable Mineral Reserves or Proved Mineral Reserves. A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in some circumstances, a Measured Mineral Resources. It includes diluting material and allowances for losses which may ...
Surplus border wall material headed for auction in Arizona was blocked by the U.S. government according to Texas officials.
