... Abstract The first fracture treatment using crosslinked guar was performed in 1969. Since then, guar and its derivative polymers have dominated hydraulic fracturing. Because of volatility and supply issues with guar gum that have surfaced during peak activity years, the industry has turned...

... chemicals when pumped together during slickwater fracturing treatments. Most FRs used in the industry are usually a combination of polyacrylamide- (PAM-) based polymers, acrylic acids, and acrylamido-methyl-propane sulfonate polymer (AMPS) copolymers, which readily interact with components of SIs...

... Abstract Microbes in unconventional gas operations can conceivably contribute to (i) degradation of polymers in hydraulic fracturing fluid, (ii) well plugging, limiting gas flow and (iii) souring and corrosion due to activity of sulfate reducing bacteria (SRB). Flowback waters from a tight gas...

... formations. Results in Fig. 4 show that using scale inhibitor 1 significantly increase stability of polymer fracturing system. Field testing The suggested scale inhibitor was implemented in April 2013. Since implementation it is continuously using with different mixtures produce water and polymer...

.... The polymers are polymerized to deliver a very high molecular weight polymer that maximizes their friction pressure contribution while it is easily pumped and handled by conventional oilfield equipment. The active polymer content range of the friction reducers is typically between 20% to 50%, but the most...

..., as well as high stability in high temperature and high shear conditions. However, borate fluids are not without notable disadvantages. The most obvious disadvantage is the presence of insoluble polymer residue that remains in the proppant pack after the gel has been broken with oxidizer breakers...

... temperature. These reservoir conditions are favorable for polymer application. Therefore, there is a potential to improve waterflood in these reservoirs by applying alkaline/polymer (A/P) flooding. This paper presents the results of a laboratory study of A/P flooding for heavy oil recovery, including...
