Well treating methods using temperature surveys
Abstract
Abstract A METHOD OF TREATING WELL TO STIMULATE PRODUCTION FROM OR TO INCREASE ACCEPTANCE OF FLUIDS IN THE WELL STRATA BY CONTROLLED SELECTIVE TREATMENT OF THE FORMATIONS OF THE WELL IN CONJUCTION WITH TEMPERATURE EVALUATION. BLOCKING AND PROPPING AGENTS ARE UTILIZED TO BLOCK OFF EACH ZONE OR STRATA AS IT TO TREATED. TEMPERATURE GRADIENT CURVES AND TEMPERATURE DIFFERENTIAL CURVES ARE UTILIZED TO DETERMINE THE STRATA TREATED AND, WHERE MULTIPLE STRATA ARE BEING TREATED, TO TRACE THE ENTRY OF TREATING FLUIDS INTO SUCH STRATA SECTIONS OR ADJACENT STRATA, AND UTILIZING THE INFORMATION OBTAINED FROM THE TEMPERATURE LOG TO DESIGN THE NEXT STAGE OF TREATMENT. THE PROCESS PERMITS STEP BY STEP TREATMENT OF ALL ZONES OF ALL IN THE WELL, AND A DETERMINATION OF THE FACT THAT ALL ZONES HAVE BEEN TREATED. BLOCKING OR DIVERTING MATERIALS MAY BE COMBINED WITH PROPPING AGENTS TO EXPEDITE THE PROCESS.
