A Novel Hydrate Strategy in a High Risk Hydrate Environment for a Fast Track Tie-in GoM Development

摘要

Under the current market environment, deep water projects are required to evolve a more robust cost solution to remain competitive within the industry portfolio, ensuring safety as priority. With such market drivers in place, this paper details the engineering behind the development of a single flowline concept that ties-in to an existing production system for a GoM deep water development and the associated challenging flow assurance aspects of that design. The development is a fast track project (approximately 1.5 year from concept to first-oil) that leverages existing subsea infrastructure. The flowline length is over 10,000 ft at water depths exceeding 5,000 ft and will tie-in to a current flow loop dead leg of more than 7 miles in length. Success of the project will set a trend and allow development for future projects, i.e. infrastructure led solutions utilizing single flowlines with rapid delivery and increased financial returns.
