COLT Case Study - Michigan
In 2008, AnTech completed a two well Coiled Tubing Drilling project for an operator in Michigan in the United States.
The performance and capabilities of both the COLT tool and the AnTech drilling team have been proven in tests, with a successful shale play drilled in Michigan, US. This was achieved with accurate precision and excellent reliability.
The success of this test is clearly demonstrated by the fact that, after the test completion, the customer offered AnTech a further two commercial wells to drill.
A second well, including an extension and an openhole sidetrack, was also successfully drilled using the COLT tools. The drilling fluid was an air/foam mix which further validated the ability of the tools to operate in high vibration environments.

Results & Benefits
- Two wells were successfully drilled
- (1,186ft) & (450ft) and hit their target zones.
- Upon completion of the campaign the customer offered another two well project.
- 100% clean health and safety record.
- Captured technical learnings and best practices.
Complete Directional Coiled Tubing Drilling Package.
Bespoke well path planning and feasibility modelling.
A range of Bottom Hole Assembly sizes suitable for re-entry and grass-root applications.
Reduced operating costs as both drilling time and rig-up time are quicker with CTD.
Underbalanced drilling protects the formation and allows production to continue whilst drilling.
