In a fracturing campaign of three wells at Field X, a new unconventional proppant technology—a rod-shaped proppant—was used. The rod-shaped proppant is a high-strength ceramic proppant with an unconventional rod shape that has the unique benefit of delivering increased proppant-pack conductivities, higher and cleaner fracture length, and improved proppant-flowback control. After 6 months of production, all fractured wells in which the rod-shaped proppant was used delivered, on average, 25% higher oil per net pay compared with offset wells fractured with conventional proppant.


Field X is a mature-waterflood field in the Central Sumatra basin. Currently, production is approximately 17,000 BOPD; most production comes from Formation Y, and a much smaller contribution comes from the shallower, but tighter, Formation X1 (reservoir characteristics are provided in the complete paper). A reservoir study for further field development of Formation X1 in Field X was conducted in 1999. On the basis of this study, it was determined that the recovery factor of Formation X1 was low (single-digit recovery). Given this low recovery factor, several options were considered to develop the remaining reserves better. The implementation of hydraulic fracturing was evaluated as one of the options to increase the oil recovery of the reservoir.

From 2006 to mid-2008, 21 fracturing jobs were performed to stimulate the X1 B sand; the jobs resulted in an average oil-production gain of 80 BOPD per well, and the overall success rate was 71%. Since that time, the operator has performed approximately 20 hydraulic fractures per year in Field X.
