... depletion tests were conducted in a two meters long sand-pack using several different oils to evaluate the effects of different process parameters, such as oil viscosity and pressure decline rate. The results show that the performance of solution gas drive depends on the pressure decline rate (or drawdown...

..., solution gas-oil ratio, gas formation volume factor, and gas and oil viscosities. It is shown that with properly characterized EOS analysis, even without the use of regression, one can match all the measured property values better than by using correlations. It is noted that one correlation can generally...

... inside the horizontal well. According to the simulation results, oil viscosity and flow velocity play important roles in the transport process, affecting the gravitational settling tendency of solid particles inside the horizontal wellbore. The results provide insight into the roles different mechanisms...

... Abstract Evaluation of hydrocarbon reserves and the design of the optimal recovery process are usually based on the assumption that the physico-chemical properties of the hydrocarbons (including viscosity) are practically constant within the limits of the reservoir or that they monotonically...

..., due to different minerals, grain sizes, pore shapes and wet ability, they may have different flow properties. There can also be variations in saturation, dissolved gas content, oil viscosity and pressure at different horizontal or vertical locations within a pool. Trapped gas saturation can also vary...

..., Lloydminster and Peace River areas. Conventional heavy oil (10 to 20 °API), which is partially recoverable by conventional in-situ methods, is less than 2% of the total resources. Most of the bitumen has a viscosity ranging from 100,000 to over 1.0 million mPa-s at reservoir temperature. It is present...
