Application of different EOR techniques for the energy and recovery of Ashal'cha oil field

Kök, Mustafa Verşan
Nurgaliev, Danis K.
In this research, utilizing the reservoir and produced oil data, different enhanced oil recovery (EOR) techniques known as in-situ combustion, CO2 flooding, and steam flooding were applied for Ashal'cha oil field in Republic of Tatarstan, Russia. For this purpose, In-Situ Combustion Predictive Model (ICPM), CO2 Miscible Flood Predictive Model (CO2PM) and Steam-flood Predictive Model (SFPM) are used. In addition to oil recovery, economic analysis of the discussed EOR applications was also conducted. By using the oil price forecast for 10 years, each EOR method is analyzed using their expenses and outcomes separately. Comparison among the EOR applications regarding the oil production, and economic feasibility was also given. Taking the reservoir and produced oil characteristics, oil production rate and economical payout time into account, it was observed that in-situ combustion is the most feasible and practical EOR method for Ashal'cha oil field.


Feasibility study of heavy oil field
Kök, Mustafa Verşan (Informa UK Limited, 2008-01-01)
In this study, application of different enhanced tertiary oil recovery methods were applied considering fluid properties and reservoir characteristics of the heavy oil field. Effect of different oil and inflation rates were analyzed considering project economic life, pay out time, cash flow, and profit to investment ratio for steam flooding and CO2 methods. CO2 injection is found to be more profitable than the steam injection due to the high cost of steam injection operations and reservoir depth.
Application of Vapor Extraction (VAPEX) Process on Carbonate Reservoirs
Kök, Mustafa Verşan; Akın, Serhat (Informa UK Limited, 2009-01-01)
The vapor extraction process, or VAPEX has attracted a great deal of attention in recent years as a new method of heavy oil or bitumen recovery. The VAPEX (vapor extraction) can be visualized as an energy efficient recovery process for unlocking the potential of high viscosity resources trapped in bituminous and heavy oil reservoirs. In this research, a total of 20 VAPEX experiments were performed with Hele-Shaw cell using three different Turkish crude oils. Two different VAPEX solvents (propane and butane)...
Performance Estimation of Water Flooding in Oil Recovery
Kök, Mustafa Verşan (Informa UK Limited, 2009-01-01)
In this research, a petroleum field (Field-A) having approximately 23.2 API gravity oil in a carbonate formation from southeast Turkey was studied. Field-A was put on production in 1989 and produced till now, which is very close to its economic lifetime. Thus, it was considered as a candidate for enhanced oil recovery and water injection. Reservoir rock and fluid data were first interpreted with available well logging, core, and drill stem test data. The data were then merged into CMG/STARS simulator. A his...
Improved oil recovery application in limestone reservoirs using alkaline solutions
Bagci, S.; Kök, Mustafa Verşan; Turksoy, U. (Informa UK Limited, 2007-09-01)
In this research, the effect of sodium hydroxide (NaOH) and sodium silicate (NaSiO4) solutions for the improved oil recovery of Raman crude oil was investigated using a one-dimensional unconsolidated limestone reservoir model. The results of displacement tests showed that sodium hydroxide (NaOH) and sodium silicate (NaSiO4) solutions were not effective on incremental oil recovery. It was also observed that injection flow rate of alkaline solution has minimum effect on Raman crude oil in scope of oil recover...
Change of physical and thermal decomposition properties of in situ heavy oil with steam temperature
Karacan, CO; Okandan, E (Informa UK Limited, 1997-01-01)
Ikiztepe crude oil was subjected to four different steam temperatures during steam injection which was applied as an enhanced oil recovery process on a linear limestone model saturated with oil. Produced oils were characterized using density, viscosity measurements, pyrolysis experiments utilizing TGA and elemental analysis runs. Results showed that produced crude oils change in measured characteristics as compared to the original oil. These changes include an increase in H/C, and cracking activation energy...
