Optimization of breaker schedules for stimulation of tight gas reservoirs

We conducted an extensive and complete investigation of breakers through a systematic and critical review of relevant publications in this area. We first presented the major breaker types and their own breaking mechanisms, then built guidelines in a flow chart for selection of breakers based on formation temperature, pressure, PH, salinity, and mineral compositions. We then developed a step-by-step procedure for optimizing breaker schedules and finally demonstrated with field case studies of two tight gas wells in Louisiana. The new knowledge helps one optimize breaker design and improve fracture treatments in tight gas wells.
