Integrated Approach for Monitoring of Sagd Wells Efficiency Basing on the Optical fiber Temperature Sensing and Geochemical Monitoring of Production

Geochemical characteristics and localization of heavy oil fields in the Republic of Tatarstan, Russia

“…Degradation degree of hydrocarbon samples grows in the following order: Oikino-Altuninskoye-Podlesnoye-previously investigated Nizhne-Karmalskoye [13] uplifts of the heavy oil field. This is probably due to a structural factor: The absolute elevation of Podlesnoye uplift is lower than Oikino-Altuninskoye.…”

“…The method proposed by the authors allows studying individual properties of bitumen at the molecular level and contributing to the effective development of super-viscous oils. At one of the considered fields, studies were previously carried out on hydrogeological and geochemical indicators [13,14]. Gas chromatography (GC-MS) methods are used to determine oil biomarkers and obtain information on the conditions of sedimentation of certain deposits, including hard-to-recover ones, and on the degree of oil biodegradation.…”

“…Gas chromatography (GC-MS) methods are used to determine oil biomarkers and obtain information on the conditions of sedimentation of certain deposits, including hard-to-recover ones, and on the degree of oil biodegradation. Geochemical properties heavy oil are considered in articles [13][14][15], where the main coefficients of oil biodegradation are analyzed. Heavy oils are characterized by complex rheological parameters, which in a certain temperature range are characterized by a wide range of non-newtonian properties [16].…”
