Chitosan/Polyacrylamide Green Gels for Water Control in High-Temperature Reservoirs
( American Chemical Society , 2022 , Article)The rheology of a gel system composed of polyacrylamide (PAM) and chitosan is studied under typical reservoir conditions. The impacts of the degree of chitosan deacetylation, temperature, and salinity on the gelation ... -
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 kinetics of PAM/PEI based drilling mud for lost circulation applications
( Elsevier B.V. , 2021 , Article)The problem of lost circulation is a direct consequence of the presence of fractures or high permeability. Lost circulation material (LCM) is used to treat the loss that occurs or proactively strengthen the wellbore of the ... -
Gelation Performance of PAM/PEI Polymer-Based Mud System for Lost Circulation Control
( EAGE Publishing BV , 2021 , Conference Paper)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 ... -
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 ... -
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 Paper)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 ... -
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 ... -
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 Paper)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 ... -
Solar thermochemical conversion of CO2 into synthetic fuels via ferrite based redox reactions
( AIChE , 2014 , Conference Paper)In this contribution, we report the synthesis NiFe2O4 and CoFe2O4 redox materials via sol-gel method. For the synthesis of these materials via sol-gel approach, the Ni, Co, and Fe precursors were first dissolved in ethanol ...
