Summary
Drilling personnel operated a dump valve using an incorrect line schematic, releasing 165 barrels of synthetic oil-based drilling fluid and cuttings overboard, including 96 barrels of oil. The alert examines an overlooked handwritten correction and recommends correcting plumbing and schematics immediately, while considering a downstream master dump valve.
