Abstract:
An extensive data acquisition program commenced with drilling a pilot comprised of a slant well and a total of ten wells in three stacked formations. The slant well was fitted with fiber optics and pressure gauges utilized to monitor frac propagation during completion. A comprehensive workflow is described in this paper and includes detailed acquired pilot data analysis, reservoir and fracture surveillance and building hydraulic fracture and reservoir simulation models. The models are constrained and calibrated with the acquired diagnostic data. The calibrated reservoir simulation model is utilized to develop forecasts and spacing charts to inform development decisions. The impact of well orientation and fracture azimuth on development is discussed in this paper.
Analysis of the acquired diagnostics reveal significant vertical pressure communication metrics on the order of 30% between stacked benches. Model-based results indicate that EUR differences between investigated well orientation configurations are on the order of 15%. To minimize waste due to observed vertical communication and potential parent-child effects with phased development, a cube-type development was recommended.
