Case Studies of Propped Refracture Reorientation in the Daqing Oil Field (SPE 106140, CARBO authored)

This paper presents case studies of refracture treatments and reorientation measurement results by surface tiltmeter mapping in the Daqing oilfield. All four treatments in this study included a novel design technique of pumping paraffin balls approximately half way through the propped treatment in an attempt to initiate fracture growth in a different orientation or through different perforation intervals. Tiltmeter mapping results indicated that fracture reorientation occurred for the majority of the refracture treatments studied.
