Parameter definition in resource calculation of a trap: A fault block example

In the early period of petroleum exploration, high value parameters were usually applied in resource calculation due to the limitation of data or knowledge. As a result, trapped resources were overestimated, which impacted exploration strategy. The key factors influencing the main parameters for resource calculation were analyzed in this paper to make estimation more realistic. Central limit theorem, probability distribution function and some other related theories were applied. Parameters were combined and multiplied under different situations to obtain multiple sets of parameters. A straight line regression of the least squares derived on a log-log plot finally determined rational parameters for calculating resources.
