Low-density workover fluid technology designed to lower the required sealing strength for operations in the fractured reservoirs of the Ordos Basin

The tight Upper Paleozoic sandstone reservoirs and Lower Paleozoic carbonate reservoirs in the Ordos Basin necessitate fracturing or acidizing to generate artificial fractures prior to production, classifying them as typical fractured reservoirs. During workover operations, the depletion of fo...
