Multi-Zone Single Trip (MST) technology is used to perform sand-control treatments individually to multiple zones in a single trip. In Deepwater installations, Well Integrity, Operational Efficiency and Completion Excellence are critical success factors for overall project returns. Well integrity is accomplished by ensuring that completion components conform to the extreme downhole well conditions; that well control is present during each stage of the completion operations; and that zones are positively isolated during the high pressure frac-pack treatments. Also, well integrity needs to be maintained during the selective isolation string deployment and throughout the production life of the well. Operational efficiency is accomplished by establishing clear guidelines during the planning phase of the wells; ensuring the right personnel are involved at the right time; identifying and eliminating any possible operational risk; simplifying tool manipulations; establishing downhole tool diagnostics that enhance decision making; and finally, improving downhole tool visualization for operational clarity. Completion excellence is achieved by ensuring completion components are fit-for-purpose for the extreme high pressure and erosive environment with maximum flow areas for optimum production, built-in redundancy for flawless executions, and software modeling to simulate downhole conditions from installation through production phases. This paper is meant to show how these features were used in the most recent completion in the Cascade field and provide recommendations for similar operations while identifying areas of improvement for upcoming installations.
