Every second year, our crew runs through a training session on a full-scale drilling & well control simulator at Bergen Maritime Academy to practice problem solving with well control methods on real scenarios. #OdfjellDrilling | Odfjell Drilling | Facebook

Well Control Primary Well Control is hydrostatic pressure provided by drilling fluid more than formation pressure but less than fracture gradient while drilling. If hydrostatic pressure is less than reservoir pressure, reservoir fluid may influx into wellbore. This situation is called "Loss Primary Well Control". Not only is hydrostatic pressure more than formation pressure, but also hydrostatic pressure must not exceed fracture gradient. If mud in hole is too heavy, it will cause a broken wellb
