Method Integrates Pressure-Transient and Fracture Area To Detect Well Interference

Hydraulic fractures created during completions are assumed to produce back to the original well. While multiwell-pad completions increase efficiencies, they complicate fracture connectivity between wells. The proximity of newly completed wells to a pre-existing producing well suggests a depleted zone that can “steal” fracture surface area. The complete paper presents a real-time method to estimate the stage-to-stage interference and well-to-well interference and their implications on completions efficiency.

Introduction

The primary challenge for the industry with regard to unconventional resource development is to optimize well spacing to improve well net present value.
