Systematic Coiled-Tubing-Efficiency Improvement Reduces Operational Time

Deepwater coiled-tubing (CT) well interventions can benefit from significant rig-time reduction and cost savings associated with improved efficiencies of surface processes. Efficiency improvement requires a systematic approach and detailed analysis of each part of the process. The efficiency methodology allows for systematic improvement in all areas of CT operations, specifically for surface activities. The total efficiency solution described in this paper requires no additional cost to service providers, and results can be seen immediately.

Deepwater Coiled Tubing

The use of CT for well intervention can provide many downhole solutions throughout the life of a well. Although there is much discussion of the financial and technical aspects of CT in the industry, less conversation is directed toward the efficiency of CT surface processes.

The expansion of analysis, specifically to CT process efficiency both before and after in-hole operations, is necessary for a holistic approach to total efficiency improvement. The stages of CT operation shown in green in Fig. 1 can be identified as five distinct surface activities.
