With any fishing operation, the challenge faced in programming is to improve the chance of recovery from the unplanned event; safely and efficiently recover the stuck object(s) and reduce costly recovery overruns and expensive, time-consuming remedial operations.
Failure to recover the stuck-object leads to deviation from or inability to execute the forward plan introducing increased risk, time and cost and potentially loss of the well.
Inclusion of HydroVolve HAMMER in planned fishing operations promotes an “as low as reasonably practicable” (ALARP) risk approach. The HAMMER delivers on the philosophy of resilience, precision and control, whilst providing the best chance of success in the planned recovery of stuck objects in fishing by delivering unimaginable extraction power to the stuck-object: far superior to that of any fishing or drilling jar.
HydroVolve HAMMER can deliver staged, precise variable impact force and frequency to significantly improve the chances of stuck-object recovery. All controllable from surface by the driller, it enables:
- unparalleled pulling and impact forces to break static friction and bonds from settled solids
- the ability to induce resonance to the stuck-object to significantly increase the dynamic action on stuck structure
- impacts to be delivered directly to the stuck object and at rates 2,500 faster than those of conventional jars, significantly improving the chance of recovery
- the ability to both rotate and circulate above the stuck object while jarring which further improves confidence and probability of recovering stuck objects
MonoVolve REDUCER, when placed across build sections, allows a significant increase in pulling force to be transferred to the stuck-object whilst protecting the host casing and drill pipe from damage and wear and also reduces the torque burden in the drill string and top-drive system.
EvoLOG in the BHA provides invaluable dynamics data capture directly from the BHA to allow assessment of actual performance of the retrieval BHA allowing future operations to be planned with confidence – improving efficiency and saving significant NPT and cost.
