Multiscale, multiphysics modeling of subsurface engineering applications
(2020-12)
Fluid flow, particle transport, and chemical reactions in porous media play a vital role in various disciplines, including hydrology, medicine, and engineering. In particular, in the petroleum industry, subsurface engineering ...
Effects of restrictions and liquid properties on liquid loading in natural gas wells
(2022-12-08)
Liquid loading is one of the main challenges in the later life of a natural gas well. Several methods have been used to unload the gas wells and remedy liquid loading, with various efficiencies. The literature revealed a ...
Experimental and numerical evaluation of shape memory polymer for lost circulation treatment in geothermal wells
(2022)
Lost circulation presents formidable challenges to drilling operations, especially in high-temperature and fractured formations. Lost circulation events increase the nonproductive time (NPT) and the total cost of drilling ...
FRAC HIT ANALYSIS IN SHALES: WOODFORD, MERAMEC AND WOLFCAMP FORMATIONS
(2020-07)
Frac hit was initially coined to refer to the phenomenon when an infill well fracture interacts with the adjacent well during the hydraulic fracturing process. But, over the years, its use has been extended to any type of ...
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 ...
PRODUCTION OF HYDROCARBONS FROM ORGANIC NANOPORES: A COMPREHENSIVE STUDY USING MOLECULAR SIMULATIONS
(2020-07)
Molecular models of organic pores are created using molecular dynamics simulations to investigate fluid behavior of confined reservoir fluids and fluid transport through nanoporous shales, aiming to reveal the underlying ...
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 ...
