K2 Field

K2 Field– ENI & Agip (Oil, Gulf of Mexico)

The K2 Field is a dual line tieback that connects wells to the Marco Polo TLP 6 miles away. The wells are in 4,150 ft deep.

MSi Kenny performed a high-level flow assurance audit of engineering contractor’s flow assurance study. MSi Kenny evaluated thermal-hydraulic models for calculation accuracy, correct methodology, and general industry “best practices”. MSi Kenny provided guidance to ENI as to how the results from the flow assurance study may be best suited to the K2 development in terms of operating procedures. MSi Kenny determined the required line size and insulation type under steady state conditions necessary to mitigate hydrate formation and deal with wax deposition. Recommendations on acceptable operating envelopes were also provided to the client. MSi Kenny performed a verification of “as-built” insulation for the pipe-in-pipe system. MSi Kenny used field production data to confirm the U-value of the installed insulation for a black oil subsea tieback. MSi Kenny performed a detailed assessment of crude oil displacement operation for the K2 system, in the event of an unplanned shutdown.

Furthermore, MSi Kenny looked at the displacement pump capacity threshold (minimum/maximum) to verify whether or not a displacement operation could be achieved. MSi Kenny evaluated the liquid management in the system during shutdown, depressurization, and displacement.
