(Source: Parametric Estimate – A method of estimating the cost of a project (or part of a project) based on one or more project-based cost factors. Historical bid data is commonly used. Using a geology-based assessment method, the U.S. Geological Survey estimated a mean undiscovered natural gas resource of trillion cubic feet and a mean undiscovered natural gas liquids resource of million barrels in continuous accumulations within five East Coast Mesozoic basins, according to a new USGS report.

    It is the purpose of this paper to describe a method of estimating the initialquantity of oil and gas present in a reservoir. The method is based on fieldoperating data and the properties of crude oil-gas mixtures. The principlesinvolved, the data required, the assumptions necessary, and an example of themethod will be given. The volumetric method entails determining the physical size of the reservoir, the pore volume within the rock matrix, and the fluid content within the void space. This provides an estimate of the hydrocarbons-in-place, from which ultimate recovery can be estimated by using an appropriate recovery factor.

    Petroleum Resources Classification System and Definitions. Estimates derived under these definitions rely on the integrity, skill, and judgement of the evaluator and are affected by the geological complexity, stage of exploration or development, degree of depletion of the reservoirs, and amount of available data.
