The recovery characteristics of four different oil shale samples were tested experimentally using the retort technique. To accomplish efficient temperature distribution, the thermal conductivity of the oil shale samples was increased by the addition of three different iron powders. The doses of iron powders were optimized for each oil shale sample based on the highest oil production value experimentally. The experiments were then modeled using the electrical heating option of a commercial reservoir simulator. The viscosity-temperature relationship was obtained by matching the experimentally obtained temperature distribution in the cores and production data to the numerical ones. After the other parameters needed for the numerical model were collected and compiled, field-scale simulations were performed and a parametric analysis was performed for different oil shale cases. The experimental and numerical results show that field-scale oil recovery from oil shales by electrical heating could be technically and economically viable.


Performance prediction of in situ combustion processes
Kök, Mustafa Verşan (Informa UK Limited, 2001-01-01)
In this research, in situ combustion performance calculations were performed using different algorithms, which were based on oil recovery/volume burned correlative methods. The correlations were based on field and laboratory combustion tube results. A computer method was developed and applied to different heavy crude oil fields. The results showed that an in situ combustion process is applicable in these fields if the volume burned is 30% for field 1 and 40% for field 2.
3-d model studies of alkaline flooding using horizontal wells
Bağcı, Ali Suat (Informa UK Limited, 2004-07-02)
In this study, the effect of sodium hydroxide (NaOH) solution for the improved oil recovery of Garzan (26degreesAP1) crude oil was investigated using two different laboratory models. The effect of injection rate on oil recovery was investigated using a one-dimensional unconsolidated limestone reservoir model. The effect of horizontal and vertical well configurations on oil recovery was also studied using a 3-D physical model and various well configurations. As previously studied, the interfacial tension mea...
Application of predictive Enhanced Oil Recovery models on a very heavy oil field
Kök, Mustafa Verşan; Akın, Serhat (Informa UK Limited, 2001-12-01)
In this study, several predictive enhanced oil recovery (EOR) techniques are used to evaluate potential thermal oil recovery techniques that could be applied on a very heavy oil (10-12°API) field located in Southeast Turkey. Two of the EOR techniques were found to be applicable after the screening process: in situ combustion and steam injection. Sensitivity of the processes to several operating parameters, such as steam injection rate, air injection rate, and steam quality, were established. It was observed...
Recovery of Turkish Oil Shales by Electromagnetic Heating and Determination of the Dielectric Properties of Oil Shales by an Analytical Method
Hascakir, Berna; Akın, Serhat (American Chemical Society (ACS), 2010-01-01)
The effect of microwave irradiation on the recovery of three different oil shale samples was studied. To enhance the microwave efficiency, three different iron powders (Fe, Fe2O3, and FeCl3) and their three different doses (0.1, 0.5, and 1% by weight, each) were added to the samples as microwave receptors. The doses of each receptor were optimized for each oil shale sample based on the highest oil or gas production value obtained experimentally. During the experimental studies, the temperature distribution ...
Determination of wettability and its effect on waterflood performance in limestone medium
Karabakal, U (American Chemical Society (ACS), 2004-03-01)
Wettability measurement methods, the effect of wettability on fluid distribution, and fluid flow in porous media were discussed, and the influence of rock wettability on the relative permeability and recovery of oil by waterflooding were investigated. Experimental studies were conducted on a total of 23 core plugs from two different limestone formations. Synthetic brine (NaCl solution) and mineral oil, which has a viscosity ratio of similar to10, were used as the test fluids. Core samples, saturated with sy...
