Aspects of the disclosure relate to wireline activities used in hydrocarbon recovery operations. More specifically, aspects of the disclosure relate to a wireline powered jarring device for hydrocarbon recovery operations.
Hydrocarbon reservoirs are becoming increasingly smaller and more challenging to access. This trend necessitates continuous exploration and adaptation to recover hydrocarbons efficiently. Researchers and engineers work tirelessly to develop novel techniques that can unlock these precious resources.
Downhole operations heavily rely on cables for data transmission, power supply and support of downhole equipment. Unfortunately, these cables often suffer damage during use. When cables become compromised, work stoppages occur as the damage is either repaired or the damaged cable is replaced. The primary culprit leading to such damage is the existence of jarring events. These jarring events are often used to free stuck components within the wellbore. These events, necessary for operational success, may stretch the cable or harm its protective cladding. In light of the potential damage, jarring events are conducted infrequently. Although infrequent, these jarring events are necessary from time to time.
Conventional production activities prioritize avoiding cable stretching or damage. This cautious approach; however, sometimes leads to cables being improperly sized for specific projects. Balancing cable robustness with operational requirements becomes critical. Engineers must strike a delicate balance to ensure cables withstand the rigors of downhole operations while not being too heavy for the intended purpose. There is a desire among field engineering staff to use the lightest cable possible to enhance field operational speed.
To address cable damage, cables must be designed to withstand jarring events without compromising their integrity. Factors like tensile strength, flexibility, and resistance to abrasion play a crucial role. Properly engineered cables minimize downtime, enhance efficiency, and reduce the need for frequent replacements.
Beyond damage prevention, cost-effective hydrocarbon recovery methods are desired. Investing in durable cables that withstand jarring events contributes to overall project costs. It is therefore more economical to use standard cables and prevent these cables from becoming damaged during operations. These solutions optimize resource utilization and reduce operational costs.
Faster production of hydrocarbons from fields is essential for meeting energy demands. Well-designed cables facilitate rapid data transmission and power delivery, ultimately enhancing productivity. Speedier recovery processes lead to optimized resource utilization and increased output.
Finally, safety remains paramount. Conducting downhole wellbore activities safely ensures both operational success and personnel well-being. Proper cable management, preventive maintenance, and adherence to safety protocols are non-negotiable. Further advantages are provided by minimizing wellbore “rework” or expensive “fishing” procedures to retail stuck components.
There is a need to provide an apparatus and methods that are easier to operate than conventional apparatus and methods to prevent cable damage. These apparatus and methods may utilize standardized wireline, limiting specialized equipment and allowing for more interchangeable parts in different wellbores.
There is a further need to provide apparatus and methods that do not have the drawbacks discussed above, namely overstressed cables, wellbore rework and the use of specialized arrangements.
There is a still further need to reduce economic costs associated with operations and apparatus described above with conventional tools. The reduction in economic costs may be derived from the use of standardized components within wellbores. Reduced economic costs may also be achieved by providing methods and apparatus that are not complicated in use or construction.
There is a still further need to provide a method for jarring equipment in a downhole environment that does not compromise the structural integrity of the cables yet also enhances downhole operations by quickly addressing stuck downhole components in subterranean wellbores.

Embodiments of the disclosure provide a method and arrangement for creating a jarring effect on a downhole device. From time to time, downhole devices become lodged within wellbores. Accumulation of sand, grit, rock, and other materials may bind downhole devices to the inner wall of the wellbore. During extraction of the downhole device, the binding may be of such significance that excessive pulling on the wireline may damage the armor or other components of the wireline. It is therefore of great importance to limit the overstressing of wireline components when these unfortunate events occur. Embodiments allow the use of standardized wireline or cables to dislodge the stuck downhole device. The method embodiments presented allow for a simplistic method for dislodging the device that does not require specialized training by field workers.

After step 508, the method continues at 510 with pulling the device up. This step elevates the internal weight preparing for release and initiation of the jarring motion. After 510, the actuator is placed into the off position at 512. The method continues with releasing the weight at 514, thereby causing the jarring/hammering action to loosen the stuck downhole component. After 512, it may be determined that the downhole component is not loosened. If it is not loosened, the method 500 may be repeated again from step 504 for successive times until the downhole device is loosened. Once loosened, the downhole device may be withdrawn from the wellbore or may be lowered past the point of binding to accomplish needed downhole testing or methods.
Embodiments of the disclosure provide an apparatus and method that are easier to operate than conventional apparatus and methods to prevent cable damage. These apparatus and methods utilize standardized wireline, limiting specialized equipment and allowing for more interchangeable parts in different wellbores.
The apparatus and methods do not have the drawbacks discussed above, namely overstressed cables, wellbore rework, and the use of specialized arrangements.
