The Base Research Program at Western Research Institute (WRI) is planned to develop technologies to a level that will attract industrial sponsors for continued development under the Jointly Sponsored Research (JSR) Program. The goals of the JSR and Base Programs are accomplished by focusing research, development, demonstration, and commercialization in three major technology areas: energy programs emphasize the increased production and utilization of domestic energy resources and include enhanced oil recovery, coal beneficiation and upgrading, coalbed methane recovery, and renewable energy resources; environmental programs minimize the impact of energy production and utilization by providing technology to clean underground oily wastes, mitigate acid mine drainage, and demonstrate uses for clean coal technology (CCT) and pressurized fluidized bed combustion (PFBC) waste solids; technology enhancement activities encompass resource characterization studies, the development of improved environmental monitors and sensors, and improved techniques and models for predicting the dispersion of hazardous gas releases. Significant accomplishments under the Base Research program are reported.
