Post fracturing temperature recovery and its implication for stimulation design
1978
In the last few years, increasing emphasis has been placed on reducing post fracturing shut in times. This trend has caused renewed interest in the relationship between breaker loadings and static fluid temperatures. Models of cooling profiles during fracturing have been extensively discussed in the literature, but scant attention has been paid to post fracturing temperature recovery. The problem has been discussed in a general way and one model has been proposed. This study presents a somewhat different model and its development. This study also discusses the application of this model to stimulation designs which require shortened breaking times. In addition, the relationship between fracture closure time and breaking times where crosslinked sand-laden gels are used is brought out and the attendant danger of poor vertical proppant distribution is discussed.
