| Number | Title | Issue Date |
| 7440283 | Thermal isolation devices and methods for heat sensitive downhole components A device for isolating a heat sensitive component includes a heat sink positioned adjacent to the heat sensitive component. The heat sink has a stepped thermal response to an applied heat. The heat sink may include two or more thermally decoupled masses. Thermal dec... | 10/21/2008 |
| 6936743 | Method for extending catalyst life in processes for preparing vinyl aromatic hydrocarbons Disclosed is a method for extending the life of dehydrogenation catalysts used to prepare vinyl aromatic hydrocarbons. The catalysts, which typically include both iron oxide and potassium containing catalysis promoter, are exposed to additional potassium delivered u... | 08/30/2005 |
| 6430507 | Method for integrating gravity and magnetic inversion with geopressure prediction for oil, gas and mineral exploration and production A method for determining formation pore pressure uses seismic data to derive an initial density model. Potential fields data are then used to derive the lower boundary of anomalous density zones (e.g., salt, shale diapirs, igneous or magmatic formations) ... | 08/06/2002 |
| 6064063 | Method for determining thermal neutron capture cross-section of earth formations using measurement from multiple capture gamma ray detectors A method for determining the thermal neutron capture cross-section of an earth formation penetrated by a wellbore from counts of capture gamma rays. The capture gamma rays are detected at spaced apart locations after bombarding the formations with high en... | 05/16/2000 |
