Operation
The WellEnTech Straight Pull Disconnect is ideal for operations where the use of a pressure-release disconnect or drop ball-actuated components is not possible. The Tool release load is determined at surface prior to running in hole and is easily adjusted by installing the required amount of calibrated shear screws. The Tool is made up as part of the BHA and run in hole. Should disconnection be required, a pull load in excess of the shear load of the screws will retrieve the upper half of the Straight Pull Disconnect, leaving the lower half in the hole. The standard internal fishing neck can then be engaged with a pulling tool in order to retrieve the lower half of the BHA during subsequent fishing/jarring operations.
