Evolution of a high near-wellbore pressure-loss-treatment strategy
Hydraulic fracturing is used extensively to improve production in the Cooper basin of central Australia. Fracturing conditions vary, with closure-stress gradients varying from 0.6 psi/ft to more than 1.0 psi/ft, Near-wellbore pressure loss (NWBPL) is the most serious obstacle to successful proppant placement, Techniques to remediate, mitigate, and tolerate NWBPL were studied and field trials were performed. Knowledge obtained from these trials culminated in a strategy to manage high levels of NWBPL and place optimal treatments in these environments.
