Experimental and advanced computational modelling study of downhole elastomer seal assemblies
(2020-05)
Elastomers seals are widely used in various drilling, completion, and production equipment. One such equipment is liner hanger which has become integral part of modern well designs. Failure of liner hanger seal assembly ...
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 ...
Geomechanical modeling of reservoir using finite element method
(2020)
The importance of refracturing horizontal wells in low permeability reservoirs is well recognized in the oil and gas industry. As a result of production from a propped open fracture, the stress changes in the reservoir. ...
ScCO2-Fluids-Rock Interactions in Nanoporous Media: Applications in Enhanced Oil Recovery and Carbon Geostorage
(2023-12-15)
A global effort to reduce atmospheric CO2 levels and mitigate global warming is ongoing. Carbon capture and storage (CCS) and enhanced oil recovery (EOR) are pivotal technologies for achieving net-zero emissions, further ...
Multiscale modeling of fractured reservoir stimulation and induced seismicity
(2020-12-18)
Natural fractures and fracture networks characteristics significantly influence the success of reservoir stimulations. Subsurface and surface investigations consider various geophysical techniques to probe and measure ...
Experimental, analytical, and numerical investigations of gas leakage through annular cement
(2020)
Cementing operations present many difficulties worldwide attributable to shallow flows. Cement sheath integrity and durability play key roles in the oil and gas industry, particularly during the drilling and completion ...
Application of in situ CO2 enhanced oil recovery in liquid-rich shale and low-temperature reservoirs
(2023-12)
The injection of CO2 presents significant potential for enhancing oil production while minimizing environmental impact by storing CO2 within the oil reservoir. However, the realization of this potential is hindered by ...
THREE-DIMENSIONAL MODELING OF HYDRAULIC AND NATURAL FRACTURE INTERACTIONS AND ITS APPLICATIONS IN RESERVOIR STIMULATION
(2020)
The ultralow permeability of the unconventional and geothermal reservoirs can be increased for economic production by hydraulic fracturing. Natural fractures and other discontinuities are inseparable elements of unconventional ...
Introducing the connected reservoir storage concept for reservoir characterization and production forecast
(2020-12)
This research presents a novel concept of the connected reservoir storage (CRSM) with which we can characterize the reservoir and accurately predict the production performance of hydrocarbon reservoirs, which have a complex ...
An Experimental, Modeling and Machine Learning Based Investigation of Stick-Slip Vibrations
(2022-08-04)
Drilling technologies have improved considerably since the first well drilled by Colonel E.L Drake in 1859. Drilling technologies enable us to safely drill complex well profiles with advanced downhole tools and sensors to ...
