Operational Situations: Drilling was carried out less than overbalanced drilling (OBD) conditions, exactly where the hydrostatic strain on the drilling mud column deliberately exceeds the formation pore strain. If the quantity of fluid while in the wellbore drops resulting from lost circulation (or almost every other motive), hydrostatic pressure https://drilling-fluid-formulatio66420.fliplife-wiki.com/347805/the_wellbore_fluid_loss_diaries
