Modeling Pinpoint Multistage Fracturing with 2D Fracture Geometry for Tight Oil Sands

摘要

Continuous progress in hydraulic fracturing technology results in pinpoint fracturing, which allows multiple precisely targeted sands to be stimulated. Recently, this technique has frequently been used in the industry with low per fracture cost and reduced cycle time. However, the design methods for fracture treatment parameters with constraints are not well presented in the literature. This article illustrates computational modeling of single-stage and pinpoint multistage hydraulic fracture designs with controllable treatment parameters to increase the knowledge base of this fracturing technique. This model integrates the fracture geometry, design parameters, design constraints, and production model. A parametric study is conducted to compare between the conventional single-stage and multistage hydraulic fracturing with their basic design concepts and postfracture benefits.
