Barite, Hematite and Cinnabar Ore Deposits in the Dusina Area, Mid-bosnian Schist Mountains
In the Dusina area, which is built up of Lower Palaeozoic metasediments, Devonian carbonate complex and Upper Palaeozoic metarhyolites unconformably overlain by Upper Permian sediments, numerous ore occurrences have been investigated: (a) "stratabound" metamorphic hematite deposits in the pre-Devonian metasediments; (b) epigenetic veins and pipes of barite (& calcite) with accessory Hg-tetrahed...
متن کاملRheological Characterization of Oil-Based Drilling Fluids – Effect on Barite Sag
Rheology is one of the key drilling fluid properties for controlling sag. Yet, the current understanding of the sag-rheology relationship is limited to a few general guidelines for reducing sag in the field. This paper reviews current understanding of sag and describes the initial stage of work aimed at finding a correlation between fluid rheology and sag performance under laboratory conditions...
متن کاملEstimation of bioavailability of metals from drilling mud barite.
Drilling mud and associated drill cuttings are the largest volume wastes associated with drilling of oil and gas wells and often are discharged to the ocean from offshore drilling platforms. Barite (BaSO4) often is added as a weighting agent to drilling muds to counteract pressure in the geologic formations being drilled, preventing a blowout. Some commercial drilling mud barites contain elevat...
