Abstract
Embodiments presented provide for a jarring device. The jarring device is used in downhole environments during hydrocarbon recovery operations. Embodiments also provide a method for safe use of a jarring device to enable freeing stuck components without damaging wireline equipment.
Claims20
A method for jarring a device to be jarred stuck in a downhole wellbore, comprising:
- running a jarring device downhole on a wireline cable;
- setting a device weight of the jarring device on to the device to be jarred;
- coupling the weight onto the device to be jarred;
- actuating an actuator on the jarring device;
- pulling the jarring device toward a surface location, lifting the weight of the jarring device;
- turning off the actuator on the jarring device;
- dropping the weight;
- and
- jarring the device to be jarred with the dropped weight.
6 more elements
An arrangement for jarring a device located in a downhole environment, comprising:
- a housing defining an interior volume;
- a metallic weight configured to be placed within the interior volume of the housing and moved from a downhole position to an up-hole position within the housing;
- a magnet arrangement configured to switch from an activated state to a deactivated state and wherein in the activated state, the magnet attracts and holds the metallic weight, the magnet arrangement placed within the interior volume at a top of the housing;
- an actuator connected to the magnet arrangement, the actuator configured to switch the magnet arrangement from the activated state to the deactivated state, the actuator placed within the interior volume of the housing;
- a motor attached to the actuator, the motor causing the actuator to switch from the activated state to the deactivated state;
- a coil spring configured with an inside surface and an outside surface, the coil spring placed within the housing, the coil spring configured to expand in diameter from a first diameter to an expanded diameter;
- a rod configured to fit within the inside surface of the coil spring and spread a portion of the coil spring to an expanded diameter;
- a solenoid configured to move a rod from an actuated position to a deactuated position;
- and
- a latching mechanism to grip the outside surface of the coil spring when the coil spring is in the expanded diameter configuration.
