Westside: Fracture Shadowing: A Direct Method for Determining the Reach and Propagation Pattern of Hydraulic Fractures in Horizontal Wells

 
Fracture Shadowing: A Direct Method for Determining the Reach and
Propagation Pattern of Hydraulic Fractures in Horizontal Wells
 
 
This presentation will report on the results of field measurements in four horizontal wells, all of which were fractured in the course of this investigation, with a total of 68 fractures. The engineering basis for these measurements was the detection of fracture shadowing created by the extending fractures. The results are used to develop a field-based engineering foundation for the determination of fracture orientation and extent, spacing between wells, and optimum number and spacing between fracture stages.
 
All of the created fractures had a consistent northeast-southwest orientation. Many were asymmetrical with respect to the wellbore. Their propagation pattern was off-balance, and none of them intersected any of the many other existing fractures within the experiment’s domain. Some of the fractures had intersected and extended beyond the adjacent cased horizontal holes. The results provided working approximations of the created fracture lengths. The major advantages of the proposed approach are simplicity of operations and consistency of results.
