Tight carbonate reservoirs require acid fracturing to boost production and achieve economical rates. These treatments can be performed in single-stage vertical wells or multi-stage horizontal wells. Key performance objectives for evaluating acid fractures include fracture conductivity, etched fracture half-length, and efficiency in executing multi-stage treatments.  This session will showcase case studies where new and innovative fluids, equipment, and modelling has been applied and how their performance compares with conventional methods.
