Jarring Operation Avoids Sidetracking and Redrilling, Saving More Than USD 1.3 Million

Drilling jar and impact tool recover stuck BHA on first attempt in Oman

Hydra-Jar AP and Accelerator AP impact force
The initial plan was to jar for 16 hours but after only 6 hours and one attempt, the operator was able to free the BHA and avoid sidetracking and redrilling. As a result of this successful jarring operation, the operator plans to use the Hydra-Jar AP drilling jar and the Accelerator AP impact tools for drilling future programs.
