DETERMINATION OF POINT OF SAND PRODUCTION INITIATION IN WELLBORES USING RESIDUAL DEFORMATION CHARACTERTICS AND REAL TIME MONITORING OF SAND PRODUCTION

摘要

lor a iomuilion in (he wcllbore, wherein ilcterinlning uses a pliiHlic model ol"llie rorinnlion, and wherein the llrsl set of eharucterisiicH conipriNcs a yield Nurlii!e, n liiliure Hurliice, a stress total strain, an einslie strain, and a plaMlli-strnin relntionHhip (900). A relalionship among a second set of characteristics of the wellhore is detertnitied using an cITective stress model, whcj"ein the second set comprises a drawdown pressure, a pi"oduelion rale, pore pressure, a temperature and a viscosity of a fluid in the wcllbore, u Ihiid How pressure in the wcllbore, a drag force of fluid flow in the wellhore, and a type of fluid flow m the wcllbore (902). A critical total strain is determined for the formation tising the first set of characteristics and the relationship (904). The critical total strain is calibrated using a thick wall test (906).
