Adsorption of CO2 on Cu/SiO2 nano-catalyst: Experimental and theoretical study
( Elsevier B.V. , 2022 , Article)Copper-based silica is a promising catalyst for several reaction pathways for CO2 conversion to hydrocarbons. The activity of this catalyst in terms of conversion and product selectivity is affected by CO2 adsorption, ... -
Carbon dioxide EGR and sequestration in mature and immature shale: Adsorption study
( Elsevier B.V. , 2020 , Article)Recently, CO2 sequestration in different shale formations has become an attractive option owing to the abundance of shale basins. However, these formations have different maturity levels and contain a variety of minerals ... -
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 ... -
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 ... -
Gelation kinetics of functionalized silica crosslinked polymeric gels used in conformance control applications
( John Wiley and Sons Inc , 2021 , Article)The potential crosslinking of three types of nitrogen-containing functionalized silica (TAAcONa, guanidine, and triamine) with polyacrylamide (PAM) has been investigated. Only triamine silica was able to crosslink with ... -
Gelation Performance of PAM/PEI Polymer-Based Mud System for Lost Circulation Control
( EAGE Publishing BV , 2021 , Conference)Lost circulation is one of the most common problems in the drilling of oil and gas wells where mud escapes through natural or induced fractures. Lost circulation can have severe consequences from increasing the operational ... -
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 ... -
Impact of aluminium acetate particles size on the gelation kinetics of polyacrylamide-based gels: Rheological and molecular simulation study
( John Wiley and Sons Inc , 2021 , Article)Inorganically crosslinked polymers have been intensively implemented for conformance control treatments in oil and gas wells at low temperatures (<90°C) because of their faster gelation time compared to organically crosslinked ... -
Impact of clays on CO2 adsorption and enhanced gas recovery in sandstone reservoirs
( Elsevier Ltd , 2021 , Article)Carbon dioxide enhanced gas recovery (EGR) is a promising technique to sequester CO2 and boost natural gas recovery from conventional depleted and unconventional tight gas reservoirs. Clay minerals are usually present in ... -
Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
( American Chemical Society , 2019 , Article)Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ... -
Investigation on the effect of mud additives on the gelation performance of PAM/PEI system for lost circulation control
( Society of Petroleum Engineers , 2021 , Conference)Lost circulation is one of the most common problems in the drilling of oil and gas wells where mud escapes through natural or induced fractures. Lost circulation can have severe consequences from increasing the operational ... -
Polymeric formulations used for loss circulation materials and wellbore strengthening applications in oil and gas wells: A review
( Elsevier B.V. , 2019 , Article Review)Drilling fluid circulation loss is referred to as “the most severe problem in drilling of oil and gas wells”, as a routine solution, loss circulation materials are added to fill any fractures and vugs that may have been ... -
Reinforcement of polyacrylamide-co-tert-butyl acrylate base gel using nanosilica for conformance control at low and high reservoir temperatures
( Society of Petroleum Engineers (SPE) , 2020 , Conference)Challenges of water shut-off, which is categorized under conformance control, are nowadays common in the oil and gas industry. The excessive water quantities produced from oil reservoirs can make the production process ... -
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 ... -
