Directional/complex wells
The authors of this paper discuss deep closed-loop geothermal systems as an alternative to traditional enhanced geothermal systems for green energy production that is globally scalable and dispatchable.
The domain expertise and technologies in the oil and gas industry such as integrated project planning and operating, extended-reach drilling (ERD), high-pressure/high-temperature drilling tools, multilateral drilling and completions, geomechanics, flow and thermal dynamics modeling, and artificial intelligence have been fueling the ongoing march for new records on ERD…
The objective of this paper is to review selected completions to provide insights for adoption of multilateral technologies, including lessons learned, operational experience, and recommendations.
