Abstract:
An underbalanced perforating system is disclosed for use in openhole completions to maximize the wellbore and matrix cleanup efficiency, to connect natural fracture patterns, and/or to enable application of new drilling fluid technology in difficult subsurface environments. The perforating system can be used for any hydrocarbon bearing formations with any lithology.
