- W2091631320 abstract "Abstract Sand production is a serious problem widely existing in oil/gas production. Most of the China offshore oil field belongs to unconsolidated sand reservoir, in which there exist various degrees of sand production. At present, sand production prediction methods often used in China are Modulus Method, by which a qualitative conclusion can be obtained that weather oil well produced sand or not, but using the method, the critical drawdown pressure without sand could not be gotten. Weizhou 12–1 oilfield is located Beibu Gulf of South China Sea, the rocks of the payzone are situated between unconsolidated and consolidated, The well depth is about 2500m to 3100m. During DST operation for W12–1-2 well and W12–1-3 well, some sands were found in the surface oil /gas separator (taken half volume of the separator). It is difficult to make decision yes or no to sand control. The authors collected the information of the oilfield (logging data, cores, DST etc.), done rock strength test in various conditions (unconfined strength, tri-axial strength, formation water soak), set a sand production prediction system to predict sand potential of Weizhou 12–1 oilfield, and gave the quantification data for critical differential pressure without sand, suggested the well completion method in final." @default.
