The United States contains an estimated three million oil and gas wells that were abandoned after they stopped producing economical quantities of hydrocarbons. State regulations require these to be sealed, but the proper plugging and abandoning (P&A) procedure for a well can cost about $100,000. It is often cheaper to maintain the annual lease payment and shut in the well. Over time, ownership...
To accurately assess geomechanical behavior in the deep subsurface for CO2 sequestration, it is typically necessary to measure the in situ stress directions and magnitudes. However, the current state of the art in stress measurement methods are often inadequate or have deployment limitations in the deep subsurface. In response to this data gap, a new thermal breakout technology is being...
SURF has proven to be an excellent venue for studying the effects and prediction of fracturing of rocks under pressure. Beginning in 2015, kISMET (Permeability (k) and Induced Seismicity Management for Energy Technologies) followed by the EGS Collab project (Enhanced Geothermal Systems) have determined a wide range of rock mechanical properties of the Poorman Formation carbonate mica phyllites...
RESPEC is currently working with Thyssen Mining Inc. and Fermilab to support their work during the Main Excavation Phase of the LBNF Far Site Facility. RESPEC has installed geotechnical monitoring equipment including seismographs and multiple point borehole extensometers (MPBX) in the underground at the 4850 Level. The seismographs are used to monitoring daily blasting activities including the...
Microorganisms are tiny cell factories that produce several metabolite, many of these are useful to mankind. Microbes can be efficiently utilized for the synthesis of fuels and high value chemicals. Most of the chemical reactions, which are harmful to the environment, can be replaced by environmentally friendly biological routes through the use of microbes. Environmental sustainability is the...
The EGS Collab project, funded by the US Department of Energy Geothermal Technologies Office, is performing intensively monitored rock stimulation and flow tests at the 10-m scale at the Sanford Underground Research Laboratory to inform challenges in implementing enhanced geothermal systems (EGS). We are gathering data and observations from the field tests and comparing to models to understand...
