摘要:Barite sag is a serious problem encountered while drilling high-pressure/high-temperature (HPHT) wells. It occurs when barite particles separate from the base fluid leading to variations in drilling fluid density that may cause a serious well control issue. However, it occur...

摘要:Abstract(#br)The ore genesis model for barite deposits in east Guizhou Province has been in dispute and the major debate focuses on whether they are product of the submarine hydrothermal sedimentation. This note presents new strontium isotope data from 19 samples of Dahebian and ...

摘要:... This work is intended to study the effect of calcium ions on the precipitation of barium sulfate (barite); then, the effect of the formed barite on calcium carbonate crystallization. The conductometric and pH methods were used to follow the progress of the precipitation rea...

摘要:...55% BaO, (2) seemingly negative linear correlations between SrO and BaO, indicating that they are ideal solid solutions of barite (BaSO 4 ) and celestite (SrSO 4 ), and (3) highly variable Sr/Ba molar ratios ranging from 0 to 2.1. Presence of barites in the Sulu ecologites ...

摘要:Abstract(#br)Different genetic types of barite from colloform and clastic pyrite-rich ores from the weakly metamorphic Saf’yanovka volcanogenic massive sulfide (VMS) deposit (Central Urals) were studied in comparison with barite from the Semenov-1 and Semenov-3 seafloor hy...

摘要:Abstract(#br)Farsesh barite in the central part of Iranian Sanandaj-Sirjan zone is a sample of epigenetic hydrothermal mineralization in dolomitized limestone, which provides appropriate chemicophysical conditions making the passage of mineral-bearing fluids possible. Barite...

摘要:...(#br)This study investigated the X-ray and radioisotope energy absorption capacity of heavyweight concrete containing barite aggregate. Concrete plates were prepared using differing amounts of barite aggregate instead of normal aggregate. Density–thickness–energy varia...

摘要:... In this study, usability of boron wastes (BW, borogypsum) and barite as a radiation shielding materials was investigated. Six compositions were shaped with various ratios of borogypsum and barite. After drying, shaped samples were sintered at 1050 °C. Sintered samples w...

摘要:Abstract(#br)The removal of barite filter cake is a challenging problem because the conventional filter cake removal treatments that use hydrochloric acid (HCl) or chelating agents were ineffective in dissolving barite containing filter cakes. Barite, or barium sulfate, is i...

摘要:... Barite, BaSO 4 , has been implicated as a possible source of Ba as well as a problematic mineral scale that forms on internal well surfaces, often in close association with radiobarite, (Ba,Ra)SO 4 . The dissolution of barite by abiotic processes is well quantified. However,...
