A coiled tubing kickoff typically refers to the process of using coiled tubing (CT) to initiate or assist in the drilling of a new wellbore or sidetrack. This method is often used in directional drilling, well interventions, and re-entry operations.
Key Steps in a Coiled Tubing Kickoff:
1.Pre-Job Planning & Design:
Assess well conditions and objectives.
Select appropriate CT size, BHA (Bottom Hole Assembly), and drilling fluids.
Ensure well control measures and safety protocols are in place.
2.Mobilization & Rig-Up:
Transport and rig up coiled tubing unit, injector head, and pressure control equipment.
Perform pre-job inspections and function tests.
3.Well Preparation:
Clean out the wellbore if necessary.
Establish circulation and verify fluid compatibility.
4.Kickoff Process:
Deploy the CT along with a mud motor and a drilling assembly.
Begin drilling operations while monitoring weight on bit (WOB), torque, and fluid returns.
Use directional tools if necessary to achieve the required trajectory.
5.Monitoring & Adjustments:
Adjust weight on bit, flow rate, and RPM for optimal performance.
Monitor downhole parameters via real-time telemetry if available.
6.Completion & Pull-Out:
Reach target depth and confirm wellbore integrity.
Retrieve coiled tubing, circulate to clean, and secure the well.
7.Post-Job Analysis:
Evaluate drilling performance and tool wear.
Generate a job report for future optimization.
