To enhance production of oil and reduce water cut, the operator and Schlumberger applied OilSEEKER high-water-cut acidizing diverter prior to matrix acidizing treatments. The selective diverter breaks when it comes in contact with oil, but remains viscous in contact with water. This allowed the operator to stimulate the oil producing zones while directing treating fluids away from water-producing zones. After the treatment with OilSEEKER diverter, oil production rose an average of 400% while reducing water cut to less than 10%. Over a 2-year period, the operator treated six wells in this field with OilSEEKER diverter, contributing to approximately 3 million bbl in cumulative oil production and USD 300 million.
