Experimental results have now been obtained with Athabasca crude oil as well as Cold Lake and Lloydminster type oils. In SAGP much...

..., together with additional experimental details. The simulator STARS was used to numerically simulate the two experiments. A 2-D gridblock system of 35´1´ 21 was used. The block size was 1´1 cm throughout, except for the column and row containing the injection well where it was 1.5´1.6 cm. Because...

... at steam temperatures. Wong et al. [7,8] were probably the first to report the experimental study of the effect of temperature on foamy oil recovery. Although they ran experiments at 50 °C, 80°C and 180 °C, respectively, using Cold Lake bitumen, their results did not reveal any clear-cut effect...

... representation of the experimental setup. The procedure used during the experiment is as follows: 1. The tube is filled with 50 ml of fluid (Oil or Glycerin / Water solution) and sealed with a stopper. 2. Using one of the lab stands the fluid filled tube is suspended in the water filled ultrasonic cleaner. 3...

... presents the results of an experimental study aimed at developing an improved understanding of the solution gas drive process in foamy heavy oil reservoirs. The main objective was to evaluate the possible range of primary recovery factors under different operating conditions. Solution gas drive experiments...

..., and a set of typical relative permeability curves for a co-current flow experiment are presented. Based on the presented experimental results, it has been found that the new saturation measurement method and the equipment is reliable and can reproduce stable dynamic saturation profiles with a minimum level...

... equilibrium was assumed in order to determine the rate of oxygen consumption from the reduction in reactor pressure with time. The experimental results have shown that carbon oxides and water are the main products of oxidation after a long duration experiment, at reservoir temperature. Typically, for a North...

... is produced. The production of sand into a perforation was modeled using a horizontal sand pack flooded with live oil. Previous sand production experiments were performed using dead oil. The pack was scanned with an X-ray computed tomography (CT) scanner. A wormhole (high porosity channel) developed within...

Table 1 summarizes the experimental conditions for these experiments. RESULTS AND DISCUSSION Figure 1 shows the cumulative NMR spectra for the four sand...

.... A laboratory investigation was conducted to study the variables involved in the immiscible CO 2 displacement of heavy oils. Experiments were conducted in a 3-D physical model, packed with 18 ° API gravity crude oil, brine and crushed limestone. A total of 20 experiments were conducted using the 3-D physical...

Twenty-six thermo-couples were inserted into the model through the back panel to monitor the temperature change at different points of the model during the experiment The front panel of the model was made of acrylic plastic plate through which the experimental process could be watched. The model...
