The use of thermal analysis methods for monitoring the development of bitumen reservoirs using thermal recovery technologies

Abstract

© 2017 Akadémiai Kiadó, Budapest, Hungary The products obtained from production wells of Ashalchinsk and Mordovo-Karmalsk bitumen fields of the Republic of Tatarstan (Russia) using thermal recovery technologies as well as the core materials recovered from the in situ combustion zone of Mordovo-Karmalsk field were studied with the thermal analysis methods. Using thermal derivatography and calorimetry, it was established that the products obtained from production wells were water–bitumen emulsions, the water content in water–bitumen emulsions was determined, the stability of water–bitumen emulsions was evaluated, and the fractional bitumen composition was characterized. Using thermal derivatography, the organic matter content in the core material and the degree of its transformation in the result of in situ combustion were determined.
