Abstract
Abstract Fracture acidizing of carbonates has yielded increases in production in many areas of the world, but depending upon rock strength and reservoir closure pressure this response may be lower than expected. Also, as a result of rock strength and closure pressure, production may decline at a higher rate than after a proppant fracture treatment. Laboratory results are presented describing the effect on strength reduction of limestone and dolomite formation samples after exposure to various acid systems. Formation samples were dry, saturated with potassium chloride water or saturated with synthetic oil prior to testing. Samples were exposed to neat, emulsified, gelled and crosslinked 15 wt% hydrochloric acids and each exhibited a differing effect on rock strength reduction. In addition, production responses are presented and compared with regard to type of acid system used for stimulation.
