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 ...
The terminology used may vary somewhat, [6] [7] but resources in a McKelvey diagram fall into three main areas: [8] Reserves, which are already discovered and commercially-viable mineral deposits, [8] [1] Contingent [8] or conditional [1] resources, whose existence is known but which are not commercially viable at present,
Conservation of Resources (COR) Theory is a stress theory that describes the motivation that drives humans to both maintain their current resources and to pursue new resources. [ 1 ] This theory was proposed by Dr. Stevan E. Hobfoll in 1989 as a way to expand on the literature of stress as a construct .
Cognitive reserve is the mind's and brain's resistance to damage of the brain. The mind's resilience is evaluated behaviorally, whereas the neuropathological damage is evaluated histologically, although damage may be estimated using blood-based markers and imaging methods.
2P, a 408mm artillery piece from the Soviet Union; 2p, a two pence British coin; 2P, rapper 2 Pistols; 2P reserves, proven reserves of fossil fuels; 2P, meaning "player 2" in fandoms which can include inverting a character's personality and appearance
The need for cognition (NFC), in psychology, is a personality variable reflecting the extent to which individuals are inclined towards effortful cognitive activities. [ 1 ] [ 2 ] Need for cognition has been variously defined as "a need to structure relevant situations in meaningful, integrated ways" and "a need to understand and make reasonable ...
This lacks a bottleneck metaphor; tasks can be performed simultaneously as long as the common pool of resource from which both the tasks pull from is not emptied. The capacity could either be a unitary pool or divided into two pools of mental resources, separated according to input modality (auditory or visual), and response required (vocal or ...
