    摘要： The present invention is directed to an in situ reservoir recovery process that uses a horizontal well located near the top of a reservoir and an inclined production well to extract bitumen or heavy oil from a reservoir. In a first stage, the top well is used for cold production of reservoir fluids to the surface, in which, reservoir fluids are pumped to the surface in the absence of stimulation by steam or other thermal and/or solvent injection. A lower production well is drilled into the formation below the top well. The top well is converted to an injection well or, if no cold production then a top well is drilled as an injector well. A portion of the bottom well is inclined so that one end of the incline is closer to the injector well than the other end of the incline. In the process, steam circulation creates a heated zone at the point of the two wells that are closest together in the reservoir.

    摘要： Techniques for determining viscosity of oil in a sample include extracting the oil from the sample using a volatile polar first solvent; using a portion of the extracted oil to determine a concentration factor of oil in the sample; determining a dry weight of the extracted oil using the concentration factor; adding a second solvent to a remaining portion of the extract, where the second solvent is less volatile than the first solvent; removing the first solvent from the remaining portion of the extract; taking a series of sub-samples from the remaining portion of the extract and sequentially removing different amounts of the second solvent from each sub-sample; measuring solvent concentrations and viscosity values of the solvent-oil mixtures of each sub-sample; and based on the measured solvent concentrations and viscosity values of each sub-sample, determining the second-solvent-free viscosity of the oil in the sample.

    摘要： A method and system for production of biogenerated gas from a zone in a reservoir are described. Microbial conversion of petroleum in the zone to biogenerated gas is stimulated. The biogenerated gas can be, for example, methane, hydrogen or carbon dioxide, or another gas. Gas including the biogenerated gas is produced from the zone to surface. While producing the gas, production parameters are monitored including reservoir pressure and an isotopic composition of the produced gas. Based on the monitored production parameters, at least one of stimulation of the microbial conversion to control the composition of the produced gas or gas saturation in the zone to control mobility of the biogenerated methane is adjusted.

    摘要： A process is described for measuring a property of oil extracted from a sample, for example, the viscosity or density. The oil is extracted from the sample using a volatile polar first solvent. A portion of the extracted oil is used to determine a concentration factor. A dry weight of the oil in the sample is calculated using the concentration factor. A second solvent less volatile than the first solvent is added to the remaining extract. The first solvent is substantially removed from the remaining extract. Different amounts of the second solvent are removed from each of a series of sub-samples taken from the remaining extract. Solvent concentrations and viscosity values and/or density values of the solvent-oil mixtures are measured for each sub-sample. Based on the measured solvent concentrations and viscosity values and/or density values, the second-solvent free viscosity and/or density of the oil in the sample is estimated.
