A Midland Basin case study on estimating production, drainage volume, and interference from multiple stacked wells. Openhole multistage (OHMS) systems are more cost-effective than the cemented casing plug-and-perf (CCPP) techniques for increasing production and reducing development costs. Understanding how much rock is being stimulated and propped is critical for unconventional producers. New imaging methods using electromagnetic energy or acoustic microemitters could represent a milestone in understanding what is left behind after fracturing. The integration of microseismic data with 3D seismic attributes, and well log and completions data is used to understand geomechanical rock properties.
