Mechanism and practice of post-fracturing soaking and pressure-controlled drainage in deep coalbed methane reservoirs

Meitan xuebao
Deep coalbed methane (also known as coalrock gas) has become a crucial growth driver for increasing natural gas production in China. Practical experience has proven that high-yield production of deep coalbed methane requires large-scale hydraulic ...

Early-flowback tracer signals for fracture characterization in an EGS developed in deep crystalline and sedimentary formations: a parametric study

, 2016
Artificial-fracture design and fracture characterization is a central aspect of many Enhanced Geothermal System (EGS) projects. The use of single well (SW) short-term tracer signals to characterize fractures at the Gross-Schonebeck EGS pilot site is ...
