Optimizing Horizontal-Wellbore and Fracture Spacing With Interactive Reservoir and Fracturing Simulation

摘要

Horizontal drilling with multistage-fracturing technology has made shale-gas reserves available globally. More recently, these technologies have been applied to new and mature oil fields. Key for economic optimization of these assets is determining the fracture spacing to use along a horizontal wellbore. Of equal importance is the spacing to use for multilaterals and the wellbores themselves to achieve optimal drainage of the reservoir. In addition, design of the fracturing treatments must be optimized. A combination of reservoir and fracturing simulation was applied. The required input data are provided through a combination of advanced log and core analyses, diagnostic fracture-injection testing (DF1T), rate-transient analysis (RTA), and characterization of fracture geometry through microseismic monitoring. flow loops.
