Machine learning for the subsurface characterization at core, well, and reservoir scales
(2020-05-08)
The development of machine learning techniques and the digitization of the subsurface geophysical/petrophysical measurements provides a new opportunity for the industries focusing on exploration and extraction of subsurface ...
Thermal performance of sandstone reservoirs for thermal energy storage: an integrated experimental and analytical study
(2023-12)
With the global plans of decarbonization in motion, major energy players and large oil and gas (O&G) companies are moving towards increasing energy generation from non-fossil sources. The implementation of renewable energy ...
Numerical simulations of wellbore cement sheath microannuli leakage in Gulf of Mexico wells
(2021-02-25)
The Gulf of Mexico (GoM) is home to more than 50,000 oil and gas wells with approximately 30,000 wells that are plugged and abandoned leading to concerns of oil and gas leakage where currently, little to no monitoring is ...
Applying machine learning models to diagnose failures in electrical submersible pumps
(2022-12-17)
Electrical Submersible Pump (ESP) failures are unanticipated but common occurrences in oil and gas wells. It is necessary to detect the onset of failures early and prevent excessive downtime. This study proposes a novel ...
EVALUATION OF LINER HANGER SEAL ASSEMBLY AND CEMENT SHEATH AS A DUAL BARRIER SYSTEM: IMPLICATIONS FOR INDUSTRY AND REGULATORS
(2020-05-08)
Robust dual barrier systems are crucial for well integrity. Regulators and industry have consistently raised the concerns in such systems regarding the testing, qualification, and prediction of leakage pathways and failure ...
Analysis and Control of Stick-Slip using a Scaled Experimental Drilling Rig
(2023-08-04)
Drilling is one of the most challenging and expensive processes involved in oil and gas production. Due to the destructive nature of the drilling process, dysfunctions are common during drilling. These dysfunctions can ...
Constitutive Behavior of Wellbore Cement
(2023-05)
Cement is one of the most integral components of a wellbore, yet minimal experimental research has been done to understand the basic processes as to what ensures a cement sheaths’ success. Globally, minimizing greenhouse ...
