Ab-Initio Molecular Dynamics investigation of gas adsorption on α-quartz (001) for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2021 , Article)
In this work, the interaction of methane and carbon dioxide on α-quartz with surface 001, with a siloxane termination (dense) surface was investigated by means of Ab-Initio Molecular Dynamics. Different temperatures were ...
Development of greener d-metal inorganic crosslinkers for polymeric gels used in water control in oil and gas applications
(
MDPI AG
, 2020 , Article)
Crosslinkable polymers, such as polyacrylamide (PAM), are widely applied for water control in oil and gas reservoirs. Organic and inorganic crosslinkers are used to formulate a gel with PAM. Although chromium has a high ...
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 ...
CO2 enhanced gas recovery and sequestration in depleted gas reservoirs: A review
(
Elsevier B.V.
, 2021 , Article Review)
Increasing CO2 emissions and global warming side effects have prompted the researchers to look for safe and reliable storage sites that have high capacity. Among the available CO2 capturing sinks, depleted gas reservoirs ...
Loss circulation in drilling and well construction: The significance of applications of crosslinked polymers in wellbore strengthening: A review
(
Elsevier B.V.
, 2020 , Article Review)
Loss circulation is one of the major concerns in drilling and well construction. The uncontrolled flow of fluids into formation while drilling or primary cementing lead to substantial non-productive time (NPT). The methods ...
Review of Iron Sulfide Scale Removal and Inhibition in Oil and Gas Wells: Current Status and Perspectives
(
American Chemical Society
, 2021 , Article Review)
Iron sulfide scale is one of the main types of inorganic scales that block oil and gas wells. Iron sulfide has polymorph crystallinity structures, which complicate its dissolving and inhibition. Hydrochloric acid (HCl) is ...
Applications of chelating agents in the upstream oil and gas industry: A review
(
American Chemical Society
, 2020 , Article Review)
Chelating agents show very effective performance in different applications in the upstream oil and gas industry. This study presents a critical review of the application of chelating agents in acidizing, scale removal, ...
Hole cleaning and drilling fluid sweeps in horizontal and deviated wells: Comprehensive review
(
Elsevier B.V.
, 2020 , Article Review)
Horizontal wells provide high drainage area within the reservoirs. Advancements in horizontal drilling technologies are utilized to develop unconventional resources such as shale gas and coal bed methane. However, wellbore ...
