Topic: Identifying Hydraulic Fracture Gradient for
           Depleted Fields, Common in Los Angeles Basin

Abstract: Hydraulic fracture gradients vary in response to reservoir pressure and near-wellbore pressure changes. Prior California DOGGR regulations suggested that operators use a typical hydraulic fracture gradient of 0.9 psi/foot to establish maximum injection pressure. DOGGR now requires operators to conduct Step Rate Tests to identify fracture gradients dependent on location. Many oil fields and formations throughout the Los Angeles basin are highly depleted from hydrocarbon production, yet sometimes still contain elevated pressures surrounding injection wells. This may lead to variations in fracture gradient with respect to location and time. Numerical modeling may be applied to anticipate pressure changes, and direct field measurements may be applied to measure fracture gradient. Ms. Wang’s presentation will discuss variations in fracture gradient with reservoir pressure, and the use of analytical and numerical techniques to evaluate fracture gradients. Ms. Wang will also describe the advanced interpretation of step rate tests. Finally, she will discuss injection stimulation for Area of Review and Zones of Endangering Influence estimates.
