The ferric oxide NPs have the potential to enhance the properties of calcium bentonite, as a low-cost alternative, to perform well in an application where the higher-value sodium bentonite is commonly used, which could provide more-efficient drilling operations and less formation damage.
contaminants to sodium bentonite. Testing has shown that seawater also has detrimental effects on the seal- ant characteristics of bentonite clay liners as well as high concentrations of various organic contaminants (Egloffstein 1994). To minimize the potential for deg- radation, some of the clay liner products contain chemically treated
2018-6-1 Abstract. A study of the utility of conventional lost circulation materials and testing methods was performed using a modified API slot tester. Five lost circulation materials were evaluated in 266 tests at both room temperature and temperature-aged conditions simulating expected geothermal environments.
2018-7-4 Sodium bentonite, found exclusively in the northwestern part of the United States, is the most widely sought-after bentonite because its hydrational ability is considerably greater than that of calcium bentonite. Hence, the name "premium bentonite" is given to sodium bentonite. Because operational need for using bentonite varies
