Drilling
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
This study evaluates the feasibility of drilling a closed-loop, unconventional geothermal system in the Pannonian Basin basement of Romania.
The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.
