New Well Requires Comprehensive Expertise To Solve Flow Assurance Challenge
A Gulf of Mexico operator planned a well re-completion of a new reservoir and planned to use an existing flowline. Historical data determined significant paraffin deposition across the flowline. Due to well reservoir modeling analysis, the preexisting flowline warranted an aggressive but confident cleaning program to ensure that the volume capacity was realized.
BlueFin conducted preliminary surveys and analysis of records, and upon thorough discussions with the client’s operations team, it was determined that in order to reach the desired outcome, a multiphase approach would be in the best interest for the operator’s schedule.
