The fundamental goal of the explorationist is to predict the performance that a reservoir will have over the production life of the field. Reservoir performance affects the economic viability of a play or prospect and is a function of reservoir system quality. Performance is expressed by
The fundamental goal of the explorationist is to predict the performance that a [[reservoir]] will have over the production life of the field. Reservoir performance affects the economic viability of a play or prospect and is a function of reservoir system quality. Performance is expressed by
* Initial production rate and production rate decline over time
* Initial production rate and production rate decline over time
* Pore throat size distribution and pore geometry (including natural fractures; see also [[Pore and pore throat sizes]])
* Pore throat size distribution and pore geometry (including natural fractures; see also [[Pore and pore throat sizes]])
* Pore volume
* Pore volume
* Permeabilities to hydrocarbon
* [[Permeability]] to hydrocarbon
* [[Water saturation]] (hydrocarbon pore volume)
* [[Water saturation]] (hydrocarbon pore volume)
* Lateral continuity, number, and position of flow units and containers
* Lateral continuity, number, and position of flow units and containers
* Reservoir pressure and drive mechanism
* Reservoir pressure and [[Reservoir drive mechanisms|drive mechanism]]
