Zoback, M D; Raleigh, C B

A method is described of hydraulically fracturing a hydrocarbon-bearing strata in a hydrocarbon producing well comprising: providing a hydrocarbon-producing well having a hydrocarbon-bearing strata, a bounding non-producing strata overlying the hydrocarbon-bearing strata, and a bounding non-producing strata underlying the hydrocarbon-producing strata; determining the maximum principal compressive stress S/sub 1/ for the hydrocarbon-bearing strata, the overlying bounding non-producing strata, and the underlying bounding non-producing strata; determining the pore fluid pressure P/sub F/ for the hydrocarbon-bearing strata, the overlying bounding non-producing strata, and the underlying bounding non-producing strata; determining the coefficient of friction u for the hydrocarbon-bearing strata, the overlying bounding non-producing strata, and the underlying bounding non-producing strata; determining the least principal compressive stress S/sub 3/ for the hydrocarbon-bearing strata, the overlying bounding non-producing strata, and the underlying bounding non-producing strata.
