Behavior of fluids in clay-hosted nanopores: insights from molecular dynamics
(2021-05)
Our understanding of fluid behavior and transport in shales, especially in organic or kerogen pore systems, has grown rapidly over the last few years. Yet, given the prevalence of inorganic material that often hosts the ...
Study towards improving the efficiency of matrix acidizing in oil-bearing carbonate formations
(2021-08)
Matrix acidizing in carbonate formations is a common technique to improve well productivity. Since more than 60% of the world’s reservoir formations are carbonates, enhancing the process of acidizing can have a significant ...
Three-dimensional fully coupled geomechanical modeling of the response of Oklahoma faults to saltwater disposal
(2021-08-05)
In the last decade, parts of the Central United States experienced marked increase in the number of small to moderate-sized earthquakes. Among all states, Oklahoma has experi-enced the most increase in the number of ...
Investigation of Hydraulic and Mechanical Cement Integrity: An Advanced Computational Study
(2021)
Cement sheath is a significant barrier to maintain the zonal isolation of wells, preventing severe consequences such as kick (or influx) accidents, environmental contaminations, and safety threats. Many previous investigations ...
Long term experimental investigation for leakage and permeability of the cement-casing microannulus
(2021-05-14)
The oil and gas industry is the primary provider of energy globally. Energy extraction from wells takes place through several stages, such as exploration, drilling and production, and then plugging and abandonment. The ...
Development of polymer gel systems for lost circulation treatment and wellbore strengthening
(2021-05-07)
Lost circulation is a frequent problem and a significant contributor to the non-productive time (NPT) in the drilling operation. Field reports and experimental studies have revealed that conventional solutions are doomed ...
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 ...
