Project 1502 - Coil Tubing Drilling and Intervention System (CTIS) Using Cost Effective Vessels

Coil Tubing Drilling and Intervention System - Using a Cost Effective Vessel addresses the growing need for a low cost well intervention system in deep water subsea wells. The enabling technology is a patented self standing riser that will provide companies with a safe and affordable way to complete, re-enter and maintain subsea wells.

Project Goals

• Establish intervention systems to reduce cost by 50% compared to MODU intervention for GoM
• Establish reliable hardware and operating scenarios
• Optimize for work in 1500 to 2000 meters of water, suitable for 3000 meters
• Strong Emphasis on Safety and Environmental Safeguards
• RPSEA Project Phase I will be completed by March 2011

The intent of Phase I of the well intervention project is to support the feasibility of the SSR as an enabler for coiled tubing intervention. Success will lead to Phases 2 and 3 to design and build a SSR system with coiled tubing to demonstrate the concept in the GoM. The successful demonstration of this project coupled with the companies involved in DeepStar and RPSEA should open the market to the GoM.

Project 2501 - Early Reservoir Appraisal Utilizing a Well Testing System

Early Reservoir Appraisal, Utilizing a Well Testing System - will develop an integrated “general source” to deal with varied disciplines needed to plan, cost and run deep water tests in the Gulf of Mexico. This project will provide a way a company can evaluate all the possibilities for deep water testing in the Gulf of Mexico to determine the optimum options to test including the planning, costing, and operational requirements.

Background

Deepwater well testing in the Gulf of Mexico (GoM) is not adequate, primarily due to the high cost of conventional equipment. Appropriate low-cost deepwater well production testing systems would provide an incentive to perform early longer term well tests to help define reservoir characteristics, economics and field management. Well testing for the deep water GoM could be the major enabler to prove up billions of barrels of oil equivalent. Recent discoveries in the deep water imply massive accumulations of oil, in the billions of barrels, and possibly multi-TCF of gas. To ascertain the oil or gas in place, production potential, and ultimate recovery factors requires more than electric logs, cores, 3-D seismic, and MDTs. Because of the high cost and extended times to drill these deep water wells, the appraisal well concept to prove commerciality is usually not economically viable for many parts of the GoM.

Nautilus International LLC (NI) is leading a world class team of experts who are evaluating the various GoM deepwater reservoirs to identify the facility design criteria required for deepwater well testing systems and will conduct a thorough analysis of various well testing systems. If systems for cost effective early testing could be developed and implemented, the impact on the deep water GoM developments would be immense. Since there are so many varied disciplines needed to plan, cost, and run deep water tests, there needs to be an integrated approach where a company can go to one “General Source” that can help optimize the well testing system for any GoM application. This initiative will provide a way a company can look at all the possibilities for deep water testing in to determine the optimum options to test, including the planning, costing, and operational requirements.

Project Goals

• Provide a roadmap for well testing options in deep water GoM
• Evaluate various well testing systems to optimize deep water well testing in the GoM
• Provide management with a tool to value the application of early well testing on deep water wells
• Provide engineers and geoscientists with a way to compare various well testing systems for deep water testing applications
• Provide a practical guide for deep water well testing designs and operations
• Create computer based spread sheet for various well testing systems for deep water applications in the GoM focusing on the four major deep water reservoir plays
• Phase I will be completed by March 2011
