Paper presented at the SPE Oklahoma City Oil and Gas Symposium, March 27–31, 2017
Paper Number: SPE-185123-MS
... Abstract Typical additives used to help suspend cement slurries at high temperatures include either biopolymers, such as polysaccharides, or synthetic polymers. The biopolymers typically degrade at elevated temperatures while the synthetic polymers tend to severely thermal thin leading to...

... and properties of surfactant and polymer, leading to poor performance in oil displacement process. For surfactant, conventional candidates such as heavy alkyl benzyl sulfonate, petroleum sulfonate, and polyoxyethylene ether are excluded due to poor properties in high salinity or high temperature...

... oxidizer breakers work effectively for well temperatures above 200°F, but breaking synthetic polymer friction reducers at temperatures lower than 150°F is significantly more challenging, even with more reactive persulfate salts. A study was conducted to completely break synthetic polymer under low...

... High molecular weight polymers are already known to reduce the turbulent drag that occurs at rapid pumping rates, allowing operators to reach higher flow rates without adding additional pumping capacity ( Toms, 1949 , McCormick 1991). According to Bird and Hassager (1977) , polymers that possess...

... Abstract Gel treatment is a cost-effective method for oilfield conformance control. Traditionally, in-situ gels formed by the reaction of polymer and crosslinker at reservoirs have been used widely to control conformance. However, a newer trend is to apply preformed particle gels (PPGs) for...

... Abstract Polymer gels used for shutting off unwanted water in producing oil wells are certainly no stranger to the Arbuckle dolomite formation in Kansas, but in years past, they have delivered short-lived results and have been only marginally successful.In November 1997, that all changed after...
