Directional Coiled Tubing Drilling Service


DATA SHEET Access bypassed reserves using our COLT BHA System for 3-5/8" to 4-3/4" hole sizes With over 70% of the world’s production coming from mature fields and with the average recovery factor of oil and gas being 35% and 70% respectively, it is not surprising that operators are looking at creative ways to access bypassed reserves and lengthen the life of their declining wells. Coiled Tubing Drilling provides the technique to directionally target these untapped sweet spots within the reservoir. By re-entering a well, you avoid the large infrastructure costs and lead times associated with grassroots drilling.

Our COLT system has been designed specifically for re-entry and thru-tubing drilling applications for hole sizes between 3-5/8" and 4-3/4" that can be used with single and multi-phase drilling fluid. The Bottom Hole Assembly is powered electrically on heptacable and is magnetically steered. It also has the unique capability of gyro orientation for casing exits avoiding the need to drill blindly near casing.

COLT is the shortest CTD BHA on the market providing safer and easier deployment and increased Weight-On-Bit for maximum lateral reach. It is designed to withstand the harsh environmental conditions that occur when drilling in underbalanced conditions and is equipped with a complete suite of sensors for instant feedback of downhole drilling conditions. This real-time feedback combined with an electric orienter that rotates continuously, gives precise control when navigating complex reservoirs and allowing build and straight sections to be drilled in the same run. By drilling a straight hole we can drill further with more weight-on-bit.

The COLT family of tools includes the supporting tools required to orient and set whipstocks and then monitor the performance of the milling run for cutting the casing window.
