Stimulated Shale Volume Characterization: Multiwell Case Study from the Horn River Shale: II. Flow Perspective

Abstract

Abstract Characterization of shale gas stimulation and production mechanisms is of paramount importance to continued horizontal well hydraulic fracture stimulation design and execution. This study integrates analyses of fracture calibration tests, hydraulic fracture treatments, production logs, pressure buildup and well interference transients, and long term production data to quantify hydraulic fracture extent, shale permeability, and the expected ultimate recovery. The study includes integrated analysis of 16 horizontal wells drilled from a pad in two opposing directions with mostly uniform length and spacing. Uncertainties in the hydraulic fracture and formation properties are reduced through rigorous modeling with analytical and numerical models. Results enable critical analysis of the shale development plan. Recommendations from this study offer insight on stimulation design modifications to yield improved well performance and increased recovery efficiency within the pad stimulated volume defined by the wells.
