To truly optimize a multi-zone stimulation treatment of unconventional reservoirs we must move away from the premise that the speed of the operation and initial production are all that determine success. Typically disregarded when applying common completion techniques are long-term production results and the time and costs associated with unplanned events, such as a screenout or stuck plug. To ensure success we must begin at the reservoir, and adopt a new focus on rock mechanics. By using formation evaluation as the primary determining factor in selecting the most suitable pinpoint stimulation technique, we can offer a low risk, operationally efficient solution that is designed to increase reservoir access and ultimately improve long term production. Therefore, the fundamental goal is to maximize reservoir access, which depending on the brittleness of the rock can be achieved by adopting a design philosophy focused on either ‘Fracture Intensity’, ‘Reservoir Diversion’ or ‘Stress Induced Complexity’ (See below for more information on these design philosophies).
