Integration of Distributed Temperature and Distributed Acoustic Survey Results with Hydraulic Fracture Modeling: A Case Study in the Woodford Shale

Abstract

Summary A unique data set was acquired in 2012-2013 during hydraulic fracturing operations in the Cana Field, Canadian County, Oklahoma. The Cana field produces from the Woodford shale using horizontal wells completed nine wells to a section. The data set was acquired during completion operations on the McCray 2-26H well and included the acquisition of distributed temperature sensing (DTS), distributed acoustic sensing (DAS), bottomhole pressure data, surface and downhole microseismic, tracer logs, and post-treatment production logs. Diagnostic fracture injection test DFIT data and other reservoir characterization information were also available from the subject and offset wells. The McCray 2-26H was completed with twelve hydraulic fracturing stages that had a variety of jet nozzle cluster spacings.
