An Investigation of the Applicability of the In-situ Thermal Recovery Technique to the Beypazari Oil Shale

In this research, a 3-D reservoir model for steam recovery was used to study Beypazari oil shale. In addition, the reaction kinetics parameters of Beypazari oil shale were determined by using the Weijdema's reaction kinetics approach in order to evaluate the applicability of these thermal methods. In the analysis of reaction kinetics experiments, two different temperature regions were observed. In the time versus temperature graph, linearly increasing the temperature zone was considered to be the fuel deposition region and the temperature peak is concluded to be the high temperature oxidation. The results demonstrated that the Beypazari oil shales that were studied were suitable for oil production by the in-situ combustion technique (24.00 lt/ton).


An investigation of polymerflooding in limestone reservoirs with a bottom water zone
Bağcı, Ali Suat; Hodaie, H (Informa UK Limited, 2003-03-01)
The effects of polymers on waterflooding of a limestone reservoir with or without a bottom water zone, as well as the effect of vertical and horizontal production wells on oil recovery, have been investigated in laboratory models. Sixteen core flood displacement tests were conducted to study the effect of relative oil-water layer thickness, polymer slug size, and well configuration in a production port. A qualitative comparison was made to show the difference between waterflooding and polymer-augmented wate...
An experimental investigation on the chemical stability of selected formation and determination of the proper type of water-base drilling fluids. Part 2. Test results
Erkekol, Selcuk; Gucuyener, I. Hakki; Kök, Mustafa Verşan (Informa UK Limited, 2006-07-01)
The objective of this study was to select the proper drilling fluid type and composition for drilling stable holes through the problems of the selected formations. This study was performed on shale samples taken from 10 wells in which hole instability was encountered to various extents during drilling the Germav formation. Both ionic and polymer inhibitions were utilized in formulating the proper drilling for the Germav formation. Ionic inhibition was obtained using KCl and NaCl. Polyanionic polymer (Pac-L)...
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.
Laboratory steam injection applications for oil shale fields of Turkey
Kök, Mustafa Verşan; Bagci, S. (Estonian Academy Publishers, 2008-01-01)
In this study, applicability of oil production from oil shales by steam recovery in a three-dimensional (3-D) reservoir model was investigated. Four different oil shale samples from several fields (Seyitomer, Beypazan, Himmetoglu and Hatildag) were used. 3-D steam injection experiments showed that steam injection was insufficient to drive oil production for the oil shale samples studied, and it was concluded that the steam injection process is not feasible in these oil shale fields.
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...
