Subsurface energy systems have historically focused on extraction of hydrocarbons through mining (coal) or drilling and pumping (oil and gas). These extractive industries have led to myriad environmental damages at the land surface as well as large greenhouse gas emissions that are driving climate change.
Subsurface mining faces challenges like minimizing surface disruption and managing waste disposal. Adapting to environmental regulations and pressures, miners …
A data mining approach provides a way to screen dependencies in reservoir and fluid data and enable subsurface specialists to estimate absent properties in partial or incomplete datasets.

In addition to subsurface coal mining (i.e., underground mining), coal reserves can also be exploited via surface mining. Surface mining is a broad term that encompasses the extraction of coal (or minerals) via strip mining, open-pit mining, mountain-top removal mining, or high-wall mining.
The meaning of SUBSURFACE is earth material (such as rock) near but not exposed at the surface of the ground.
