Effect of surface morphology on methane interaction with calcite: a DFT study
(
Royal Society of Chemistry
, 2020 , Article)
Natural gas, consisting primarily of methane, is found in carbonate reservoirs of which calcite is major component. However, the complexity and heterogeneity of carbonate reservoirs remain a major challenge in estimating ...
Enhancement of flocculation and dewaterability of a highly stable activated sludge using a hybrid system of organic coagulants and polyelectrolytes
(
Elsevier Ltd
, 2020 , Article)
This study investigates the influence of hybrid coagulation-flocculation system on the flocculation and dewaterability efficiency of a real highly stable activated sludge obtained from the membrane bioreactor tank of a ...
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
(
Elsevier B.V.
, 2016 , Article)
In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ...
Effect of CO2 adsorption on enhanced natural gas recovery and sequestration in carbonate reservoirs
(
Elsevier B.V.
, 2018 , Article)
In this study, CO2 injection for the purpose of Enhanced Gas Recovery (EGR) and sequestration after primary recovery is investigated on Pink Desert limestone from Edwards Plateau formation in central-west Texas. In this ...
Gelation of Emulsified Polyacrylamide/Polyethylenimine under High-Temperature, High-Salinity Conditions: Rheological Investigation
(
American Chemical Society
, 2018 , Article)
Emulsified gels are proposed as a method of water shut-off in oil and gas reservoirs and are designed to separate into a water phase and an oil phase under reservoir conditions. A first of its kind rheological study on the ...
Machine Learning for Capillary Pressure Estimation
(
Society of Petroleum Engineers (SPE)
, 2022 , Article)
Capillary pressure plays an essential role in controlling multiphase flow in porous media and is often difficult to be estimated at subsurface conditions. The Leverett capillary pressure function J provides a convenient ...
