【 摘 要 】

During this reporting period our project focused on (1) review of case studies of remediation of centralized and commercial drilling fluid disposal (CCDD) sites in Texas, and (2) information transfer with preparation of a proceedings paper and a workshop/short course. Texas remediation of certain drilling-fluid disposal sites includes examples at CCDD sites as well as commercial oil reclamation sites and saltwater disposal sites that also disposed of drilling fluids in pits. Site investigations range from qualitative visual inspection and assessment to comprehensive hydrodynamic, chemical, and geophysical analyses of wastes and groundwater. A range of techniques has been used to evaluate waste material, soil, groundwater, and surface water for potential contamination with hydrocarbons, chemicals, saltwater, and naturally occurring radioactive materials (NORM). Most constituents of concern measured in these studies are below regulatory action levels and established guidelines. A proceedings paper summarizes results presented in this and previous semi-annual progress reports will be part of the Transactions of the Gulf Coast Association of Geological Societies (GCAGS). A technology transfer workshop also was prepared as part of that Annual Meeting of the GCAGS to be held in November 2002.
