As wells across the US shale sector are brought back onto production, they may want to do so strategically to learn about the connectivity of their wells. One challenge will be in selecting a model that delivers the most insight. Developed by the large shale producer, its new way to monitor interactions between horizontal wells is now available as a commercial software. The concept is considered a stepping stone toward real-time fracture design. New commentary from the SPE Reservoir Advisory Committee (RAC) provides key high-level insights on the potential consequences of long-term shut-ins on conventional and unconventional reservoirs.
