| 摘要 | A system and a computer implemented method for determining a value of information are described herein. The method includes drawing a plurality of synthetic prior earth models from one or more prior distributions for a plurality of well locations and generate from each prior distribution synthetic data; and drawing a plurality of posterior earth models from a posterior distribution for the plurality of well locations, the posterior distribution being generated through stochastic inversion from the synthetic data and the plurality of posterior models are drawn from each of the plurality of prior earth models. The method further includes calculating a difference or a ratio between a weighted value prior and a weighted value posterior and calculating a sum over a plurality of well locations of the difference or the ratio to obtain the value of information. | ||||||
