The method of estimation is called deterministic if a single best estimate of reserves is made based on known geological, engineering, and economic data. The method of estimation is called probabilistic when the known geological, engineering, and economic data are used to generate a range of estimates and their associated probabilities.

Reserves estimation in tight gas reservoirs PetroWiki

Volumetric methods can be used to estimate reserves from high permeability, blanket, and depletion drive gas reservoirs. In such reservoirs, the drainage area and gas recovery efficiency are usually known with reasonable certainty thus, the volumetric method can provide relatively accurate estimates of OGIP and reserves.

Machine Learning Algorithms and Their Appliion to Ore

Estimation of ore reserve is essentially one of the most important platforms upon which a successful mining operation is planned and designed. Reserve estimation is a statistical problem and involves determination of the value (or quantity) of the ore in unsampled areas from a set of sample data (usually drillhole samples) X1, X2, X3, .

Narrowvein modelling and Mineral Resource estimation

Narrow veins are major sources of many commodities, including gold, silver, tin, tungsten, coal, uranium and sometimes copper, lead and zinc. Mining this narrow style of mineralization can be considered as relatively high risk, not only due to the high cost of exploration and mining per unit of metal, but also to the frequently limited size of the resource.
