... especially in mid to late SAGD life. However, this point isn't consistent with current numerical simulations. Therefore, this paper presents an improved numerical simulation method of non-condensable gas co-injection to validate the physical simulation results. Solubility experiments of methane, nitrogen...

... to develop procedures for accurate and repeatable analysis of mercury concentrations in gas sampling systems. Methane was contaminated with precise concentrations of mercury to facilitate a range of experiments examining both the contamination and scavenging behaviour of mercury in sample chambers...

... alternative among the existing CO 2 -recycling solutions. CO 2 hydrogenation has many chemical paths depending on the catalyst, and multiple value-added hydrocarbons can be generated. This research looks into a catalyst development for converting high CO 2 gas field into methane and alcohols. The study...

... of various gas solvents (methane, CO 2 , and air) aiming to select the most competitive and economic formula were tested with a certain set of pressure depletion rates. The physics of the foamy oil flow for different solvent mixtures and depletion conditions were analyzed using pressure profiles acquired...

... Abstract Production of methane from coal seems is achieved by pumping out large quantities of water leading to cleat pressure drawdown and hence methane desorption from the matrix, its diffusion through the micropores to the cleat system and out of the wellbore. A coupled numerical model...

...Selecting First Separator Stage Conditions The pressure and temperature selected in each stage of the separator must produce output gas that has a lower CO 2 concentration, a large volume of vapor, high methane concentration, and a very low volume of high molecular weight components (C 9...

.... Although analysis using a GC will give amounts of methane, ethane, propane (paraffins); napthenes and aromatics are not explicitly analyzed. Also it is very difficult to distinguish between wet gas, condensate and oil using present day GC instrumentation. Another critical element is the speed at which...

... Abstract The objective of this research is to estimate the possibility of microbial restoration of methane deposits using subsurface sequestered CO 2 and indigenous anaerobes in depleted oil fields. The most important factors are the efficiency and velocity of methane conversion by indigenous...

... Abstract Methane is a clean-burning fuel that is the main component of natural gas. We have attempted to develop a methane-producing system using indigenous microbes in depleted oil fields. In particular, we aim to combine a microbial conversion of the residual oil into methane...

..., such as for Methanococcus sp. 8 , 9 ) and for Methanocalculus sp. 10 ) . The inoculated samples were then incubated at 50°C for 9 to 10 days under atmospheric pressure. Separation by roll tube method When the HPTB and MPTA grew, hydrogen or methane production, respectively, was verified by gas chromatography...

... Abstract The methane pressure cycling process is an enhanced oil recovery scheme intended for application in some heavy oil reservoirs either after termination of primary, or waterflood, production. The essence of the process is the restoration of the solution gas drive mechanism...

... and molecular vibration absorption. Current sample contamination assessment technique uses the color absorption and the methane molecular vibration absorption. The downhole GOR measurement uses the molecular vibration absorptions of methane and oil. Color Absorption For most crude oils, the color...

... and the buyer, even long before the development stage. An alternative marketing strategy would be to convert the natural gas mixture to syngas (CO + H2) by the partial oxidation and dry reforming of methane with carbon dioxide or steam reforming and CO2 reforming; the syngas can then be used for the production...

... provide examples of how this is manifested in practice. Viscous fingering provides an explanation for the high values of residual water saturation. Conclusions from this paper are important for scaling results from laboratory tests to field applications. Applications occur in coalbed methane and gas...

... Abstract The production of coalbed methane in the United States dates back to the early 1930's. Yet it was not until the early 1980's that research and development projects began to show the enormous potential of this energy resource. These efforts have resulted in the rapid commercialization...
