Hydraulic Fracturing in the Congo Onshore: Continuous Optimization Improves Productivity

This paper describes the successful ongoing process of optimizing hydraulic fracturing designs in a well campaign in Congo<br>onshore to create best practices for continuing development.<br>The fracture design program began by characterizing and evaluating the rock formation and its compatibility with stimulation<br>fluids, including mineralogical and geomechanical properties, as well as regained permeability. For example, laboratory<br>testing determined that the formation was soft and highly sensitive to water, indicating that a water-based fracturing fluid<br>would require specialty additives to minimize formation damage.
