... of spallation, erosion, fracturing, chipping and cutting. This technology has exciting applications in heavy oil recovery. Introduction The Hydratherm system can be employed for drilling oil, gas or geothermal wells. It may also be adapted for mining, boring, tunnelling or the cutting of chambers...

... downstream sections of the well to be shut-in. The application of this technique enabled the light oil test to mimic the operation of a heavy oil reservoir using THAI. Very high oil recoveries were achieved in the tests, up to 85% OOIP. During wet in situ combustion (ISC), Wolf Lake oil was upgraded to 20...

.... Floods were also carried out in unconsolidated cores using combinations of an alkali, surfactant and a polymer. Individual slugs were injected sequentially in some of the experiments, while the three components were mixed and injected as a single slug in other experiments. Oil recoveries in the two cases...

... for the poor recovery performance, not to mention a solution to the problem. The size of the target oil and the constant threat of field abandonment, led to the approval of a research project in late 1993 as part of the portfolio of PRAVAP, Petrobras Advanced Oil Recovery Program. Its goal was twofold: verify...

... Abstract An exciting new future of large-scale carbon dioxide enhanced oil recovery awaits Alberta's depleted oil fields. This paper presents the potential and how the necessary infrastructure could be developed. Such an infrastructure currently exists in the Permian Basin of West Texas...

... Abstract A new air injection technique, low temperature oxidation (LTO process), is described. Improved oil recovery from deep, light oil reservoirs is achieved by removing the oxygen in the injected air by spontaneous LTO reactions with the residual oil in the reservoir. The product...

... Abstract Many heavy oil reservoirs in Turkey are not suitable candidates for thermal recovery methods, such as steam injection and in-situ combustion. The immiscible CO 2 or gas displacement process appears to be a very promising enhanced oil recovery technique for these heavy oil reservoirs...

... the horizontal well and the production performance. Results obtained demonstrate that the systems without stinger installed yielded a sharper water cone profile, earlier water breakthrough, and a significantly lower oil recovery than those with stinger did. Installing a stinger flattened the water cone shape...

... Abstract For predicting the performance of water injection in naturally fractured reservoirs, scale-up of the recovery data from immersing an oil-saturated core into water is commonly used. Oil recovery from some of the naturally fractured reservoirs of the North Sea has been better than what...

... conditions. Results of oil recovery from low permeability Spraberty cores during CO 2 injection experiments are promising. A mathematical model has been developed for scaling-up the laboratory CO 2 ternary oil recovery to pilot scale to assist pilot design. The result indicates a good potential of CO 2...
