I whle drilling a well a rock layer Is encountered at 10000 ft. depth with an excess pressure (overpressure) of 150 psl. An overpressure zone has fluld pressures In excess of the hydrostati gradlent. If the overburden densfty Is 2400 kg/m" and the fluld column Is water what Is the effectIve stress at this depth? 5921.17 psl 57.68 MPa 4127.6psl 5549.0psl
