The objective of this research is to investigate the rheological and thermal properties of bentonites for water base drilling fluids. Rheological experiments were performed with 4 different bentonite samples and clay percentages, cation-exchange capacity (CEC), swelling volume, pH, and physical and rheological properties of the samples are determined. The thermal behaviors of bentonite samples were investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) techniques. It was observed that all bentonite samples exhibit 2 weight loss events on heating. Similar behavior was observed with the bentonite samples studied in the literature.

Rheological properties of asphaltite-water slurries Hicyilmaz, Cahit; Ozun, Savas; Altun, Naci Emre (American Chemical Society (ACS), 2006-09-20) In this study, the rheological characteristics of asphaltite- water slurries ( AWSs) were investigated with respect to some of the most important parameters in the preparation of slurries. The effects of pulp density, chemical addition, pulp pH, and particle size on the rheological behavior and viscosity of AWSs were studied. The role of demineralization of asphaltite was also investigated, and rheological properties of raw and relatively demineralized asphaltites were compared. Results showed that viscosit...
Rheological behavior of bentonite suspensions Kök, Mustafa Verşan; Gücüyener, Hakkı (Informa UK Limited, 2000-01-01) The objective of this research is to investigate the concentration effect on the rheological properties of different bentonite suspensions. Experiments were performed with different bentonite type and concentrations and the results were evaluated by different rheological models (Bingham plastic, Power law, Sisco, Casson, Herchel Bulkley and Robertson Stiff) describing the flow of non-Newtonian fluids by mathematical equations in terms of shear rate and shear stress.
Analytical investigation of wet combustion process for heavy oil recovery Bağcı, Ali Suat (Informa UK Limited, 2004-12-01) Analysis of combustion tube data produced from experiments performed under realistic reservoir conditions is currently the most valid method of investigating in-situ combustion process. In this study, the optimization of water-air ratio for B. Kozluca heavy crude oil, and the comparison of the performance of dry and wet forward combustion processes were studied. An analytical model was used to extend the laboratory results so that the oil production and steam zone volume can be estimated under field conditi...
Rheological evaluation of polymers as drilling fluids Kök, Mustafa Verşan (Informa UK Limited, 2003-01-01) Polymers are recently found and still developing materials to overcome some drilling problems where conventional drilling fluids are not satisfactory enough. Simply, they are the best materials to use since they are non-toxic and do not cause serious environmental problems. In addition, polymeric drilling fluids may have properties such as better carrying capacity, less fluid loss, and thinner filtration cake depending on their composition and concentration. In this research, rheological parameters of two d...
Thermogravimetry of selected bentonites Kök, Mustafa Verşan (Informa UK Limited, 2002-10-01) In this research the application of thermal analysis techniques (TG-DTA) to the characterization of bentonite samples is presented. The thermal behavior of 4 bentonite samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) techniques. It was observed that all bentonite samples exhibit 2 weight loss events on heating. The first weight loss event corresponds to the loss of molecular water from the exchange layer, whereas the second weight loss event corre...
