Özet:

In this study, geological properties and characterization evaluations of Seyitgazi-Eskişehir region bentonites were investigated. Also, usability for drilling the bentonites was investigated according to the American Petroleum Institute (API) standards. Bentonite samples were collected from different locations and named ES-1A, ES-1B, ES-1C, ES-2A, ES-2B, and ES-3 for analysis. The geological evaluations were examined with formations and occurring mechanisms. Characterization of the samples were examined through XRF, XRD, Rietveld, FT-IR, and optical microscope analysis. Also, the suspensions made with the samples investigated flow properties with a rotary viscometer and filter press. With the results of the mud flow analysis, suitabilities for drilling operations were determined.
