Economic optimization of unconventional resources requires improvements in the number of effective clusters and sizing fracture treatments that are appropriate for the lateral and vertical spacing. Two key challenges facing operators is routinely and economically determining the number of effective clusters within a stage and determining the resulting fracture lengths. This presentation focuses on a methodology for determining the number of open clusters at the end of a fracture treatment and the resulting fracture geometry. The methodology has been calibrated with multiple diagnostic methods, including fiber optics, stepdown tests, radioactive tracing, oil and water tracers, fracture modeling and RTA technologies. Results will illustrate the effects of perforation size and number, cluster spacing, stress shadowing and diverter performance. The effects of cluster performance on fracture length and asymmetric fracturing will be discussed in relation to parent and infill development. The solutions can be applied to each stage of the wellbore, unlike post-job techniques which often only focus on a few stages.
