  • Patent number: 7532984
    Abstract: Method and system are disclosed for determining hydrocarbon CDVs in a multiphase environment. The method and system involve calculating a total hydrocarbons volume from an apparent oil volume and an apparent gas volume. The apparent oil volume is determined using C/O data from a nuclear logging tool operating in inelastic neutron scattering mode. The apparent gas volume is determined using neutron porosity data from a nuclear logging tool operating in pulsed neutron capture (“PNC”) mode. It is also possible to determine the total hydrocarbons volume using log data from formation thermal neutron capture cross section measurements, or a cased hole formation resistivity tool. The total hydrocarbons volume is then used to back-calculate the total hydrocarbons CDV at various formation depths using the logged C/O data. The resulting independently calculated total hydrocarbon CDV may be used for proper matching of log data and simulation results for history matching purposes.

  • Publication number: 20090114387
    Abstract: Described herein are methods for identifying compounds useful for producing heavy oil from an underground reservoir. The methods facilitate the development of chemicals with improved physicochemical features. The methods generally involve first identifying a physicochemical property of a compound that needs to be improved in order to increase the efficiency of heavy oil removal from underground reservoirs. Next, the physicochemical property is calculated by molecular modeling using semi-empirical or ab-initio calculations. By modifying the molecular model of the compound, the targeted physicochemical property can be optimized. After a suitable compound has been identified, the compound can be synthesized and evaluated.

  • Publication number: 20080164037
    Abstract: A technique distributes localized stress acting on a tubular. The tubular is formed with an inner layer and an outer layer that is compliant relative to the inner layer. A force distribution material is disposed between the inner layer and the outer layer to spread any concentrated loads acting against the tubular. The compliant nature of the outer layer causes it to distort against the force distribution material when acted on by a concentrated external load. The outer compliant layer and the force distribution material cooperate to isolate and protect the inner layer from displacements of the surrounding subterranean material.
