Jt After drilling a maximum of 49* below the aurface and interaediate caaing, a pressure teet shall be obtained to aid in determining a formation fracture gradient either by testing to fonaation leakoff or by testing to a predetermined equivalent aud weight. The propoaad mmttirtf riapth for interaediate casing shal l be based on the surface caaing prsssure test or on subsequent preeeure tests.
