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 ... -
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 ... -
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 ...
