SNLEE sells a fully comprehensive range of pack offs, including specialized packages which greatly reduce manual handling and enhance the safety of any wireline intervention. Pack offs acts as a type of well control by forging a grease assisted rubber seal around a wireline. This seal serves to contain wellbore fluids and gases in the stack. Pack offs use a soft rubber seal to strip wellbore fluids from wireline. These waste fluids are returned to an appropriate containment system via a waste drainage hose.
