  • Patent number: 8214243
    Abstract: Systems and methods for managing large oil field operations are provided. A oil field map is displayed on a monitor. The oil field map includes oil well objects, oil field facility objects, surface work crew objects, sub-surface work crew objects, safety zones objects, and work equipment rig objects associated with at least one work crew object and having a geographic locater device for tracking its location, each of the objects include a date attribute and a location attribute. The oil field map is customizable by date and has a date selector tool. At least two surface or sub-surface work crew objects are scheduled via a domain-specific software application from which the surface or sub-surface work crew object was extracted. The scheduling of the surface or sub-surface work crew objects is repeated until all surface and sub-surface work crews are scheduled for a date range of interest.

  • Patent number: 8051020
    Abstract: A method for predicting properties of lubricant base oil blends, comprising the steps of generating an NMR spectrum, HPLC-UV spectrum, and FIMS spectrum of a sample of a blend of at least two lubricant base oils and determining at least one composite structural molecular parameter of the sample from said spectrums. SIMDIST and HPO analyses of the sample are then generated in order to determine a composite boiling point distribution and molecular weight of the sample from such analysis. A composite structural molecular parameter is applied, and the composite boiling point distribution and the composite molecular weight to a trained neural network is trained to correlate with the composite structural molecular parameter composite boiling point distribution and the composite molecular weight so as to predict composite properties of the sample. The properties comprise Kinematic Viscosity at 40 C, Kinematic Viscosity at 100 C, Viscosity Index, Cloud Point, and Oxidation Performance.

The carbon membrane includes an asymmetric hollow filamentary carbon membrane, including a partial carbonization product of an asymmetric hollow filament including an aromatic imide polymer material. The carbon membrane is at least 95 weight percent carbon, and has a dense layer located in the outside surface portion of the hollow filamentary membrane and a porous base layer continued from the dense layer and located in the inside portion of the hollow filamentary membrane.
