Method and Apparatus for Evaluating the Potential Effectiveness of Refracing a Well

机译:评价油井改造潜力的方法和设备

摘要

A method for evaluating the potential effectiveness of refracing a previously fracked oil/gas well is accomplished by isolating a plurality of previously fracked zones of an oil/gas well in a formation and measuring the fluid flow rates from the isolated zones using a three phase flow meter positioned within the well at or near the previously fracked zones. The zones may be isolated by an isolation assembly which includes two packers connected by a perforated pipe and attached to a tubular positioned within the well.
