Contact网页2020年12月1日open access Abstract Strenuous attempts for replacing barite by novel competitor ores with titanic reserves as alternative weighting materials to overcome formation pressure problems were made owing to the big cost of barite-based drilling fluids.
Contact网页The weighting material alternatives evaluated were hematite and ilmenite, which ranked between 5.5 to 6.5 and 5 to 6, respectively on Mohs scale. The Mohs scale values indicate that both alternative weight materials are more abrasive than barite.
