SkoFlo Subsea Back Pressure Regulators (BPRs) are anti‐siphoning, self‐regulating devices that create back pressure in chemical injection lines to prevent uncontrolled delivery of chemicals into production wells. BPRs prevent chemicals from draining into injection points when a chemical hydrostatic head exceeds injection pressure and production wells become sub‐ambient.
Subsea BPRs regulate inlet pressure when the well pressure falls below the factory set point of the device. It achieves this regulation with a simple debris tolerant mechanical device that does not need power or communication to the SCM. BPRs are self-regulating devices activated only when required or needed.
