This paper reviews the fracturing history in the Cooper Basin and summarizes the results of over 650 fracturing treatments characterised by high tectonic stresses, high fracturing pressures, high reservoir temperatures, and stacked reservoir lithologies of sands, shales, and coals. Initial treatments targeted multiple moderately high permeability (1-10 md) formations, while multi-staging operations are now targeting single, less extensive, lower quality reservoirs. The paper discusses the techniques used for predicting and designing for natural fracture leakoff, high near wellbore pressure losses and high fracture gradients. It shows the changes in fracturing ideologies and how they have altered the completion strategies, predicted fracture geometries, fracturing materials, treatment schedules, and post-frac production.
