Screening criteria for microbial for processes

Description: The National Institute for Petroleum and Energy Research (NIPER) has maintained a microbial enhanced oil recovery (MEOR) field project data base since 1985. One of the major goals of this data base is to continue to document characteristics of reservoirs used for MEOR field projects and to assist the US Department of Energy by revising published screening criteria for MEOR processes. Since the last update of this data base in 1987, the number of MEOR field projects entered has increased from 39… more

Investigations of mechanisms of microbial enhanced oil recovery by microbes and their metabolic products

Description: Experiments at NIPER have demonstrated that oil mobilization by microbial formulations is not merely the result of the effects of the metabolic products from the in situ fermentation of nutrient. A combination of two microorganisms, Bacillus licheniformis, NIPER and a Clostridium species (NIPER 6) was determined to be an effective microbial formulation for the recovery of residual crude oil in porous media. Flask tests with various nutrients and environmental conditions were used to evaluate th… more

WSRC-TR-2003-00130

Description: High level waste at the SRS F- and H-Area Tank Farms consists of both sludge and supernate fractions. Supernate contains soluble species. Sludge contains both insoluble species and entrained supernate. The nature and extent of contamination present on waste generated during operation of the F- and H-Area Tank Farms is a function of the tank, the nature of the job generating the waste, variability in waste handling techniques, and other factors. Historically, supernate-contaminated waste had bee… more
