Offshore oil platforms require accurate flow measurement to pump drilling mud at controlled, high pressures through the drill pipe to cool and lubricate the drill bit, deep in the seabed. A Brooks Instrument metal tube variable area flow meter enables consistent, repeatable pumping of drill mud under these severe process conditions.
The engineers from an oil and gas company specified the MT3809 metal tube variable area flow meter. The flow meter has been installed on the offshore platform to precisely measure drilling mud flow at a consistent rate through a drill pipe. Once the mud reaches the drill bit, the mud will cool off and lubricate the bit which is in a narrow shaft in the seabed. The drill bit also has holes for the mud to travel through to prevent any clogging. Also, if there are any rock cuttings, the mud will transport the cuttings back to the surface.
Additionally, a Brooks Instrument MT3809 metal tube flow meter with its corrosion resistant and stainless-steel housing can withstand high pressures up to 885 bar, a mixture of process fluids, and a range of temperatures from -198°C/135°F to 420°C/788° F, ideal for a hazardous environment such as oil drilling. The simple design enables easy installment and maintenance which is preferred for an application out at sea.
Flow Scheme
Although flow meters are a small component compared to the size of an offshore oil platform, their function is critical in keeping the drill bit and drill pipe operating at scale. The flow meter also minimizes operational downtime and production costs for a harsh and demanding application.
