Resource estimates are undiscovered volumes, or volumes that have not yet been drilled and flowed to surface. A non-reserve resource, by definition, does not have to be technically or commercially recoverable and can be represented by a single, or an aggregate of multiple potential accumulations, e.g. an estimated geological basin resource. [14]
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
The United States maintains a Strategic Petroleum Reserve at four sites on the Gulf of Mexico, with a total capacity of 727 million barrels (115.6 × 10 ^ 6 m 3) of crude oil. The maximum total withdrawal capability from the United States Strategic Petroleum Reserve is 4.4 million barrels (700,000 m 3) per day. This is roughly 32% of US oil ...
The reserve portion of the ratio is the amount of a resource known to exist in an area and to be economically recoverable (proven reserves). The production portion (denominator) of the ratio is the amount of resource produced in one year at the current rate. [1] RPR = (amount of known resource) / (amount used per year)
Crude oil production Natural oil seeps such as this in the McKittrick area of California were used by the Native Americans and later mined by settlers.. The history of the petroleum industry in the United States goes back to the early 19th century, although the indigenous peoples, like many ancient societies, have used petroleum seeps since prehistoric times; where found, these seeps signaled ...
Classification and management of natural resources such as minerals and petroleum are classified using differing schemes. [4] [5] In 1997, UNECE published the United Nations Framework Classification for Reserves and Resources of Solid Fuels and Mineral Commodities (UNFC-1997) as a unifying international system for classifying solid minerals and fuels.

The Competent Persons Report ("CPR") published by RPS Energy on May 8, 2017, provided the following estimates of reserves, contingent resources and initially in place volumes; [8] Reserves. 1P: 28.1 million barrels (4.5 million cubic metres) of oil equivalent; 2P: 37.3 million bbl (5.9 million m 3) 3P: 49.3 million bbl (7.8 million m 3)
