Horizontal Drilling with Dual Channel Drill Pipe
Vestavik O.M., Thorogood J., Reelwell;
Bourdelet, E., Total; Schmalhorst B., Roed J.P., Deutsche Erdoel AG
Development supported by:
Solving challenges
Challenge 3. No ECD 3. ECD
2. Buoyancy –reduce Torque & Drag
HeavyLight
2. Torque and drag 1. Cuttings -removed above BHA
1. Cuttings - stuck pipe
Solution
Solving the ECD challenge Horizontal drilling example
Managed Gradient Driling:
Gradient can be held constant whether pumping or not.

Results summary
1. Efficient hole cleaning confirmed
2. All procedures and models verified
3. HOL fluid solution verified
4. Operational excellence achieved
Operation performed according to plan and budget
Sample of some larger cuttings
• Reduce loss and formation damage
• Reduce risk of pack-off and stuck pipe
• Increase casing setting depth
• Increase horizontal reach
