Production / test manifold

Company / operator legend practice (API 6A, API 521, API 537) / PIP PIC001

Drawn as

Two parallel headers (production and test) with several incoming well lines; each well line has a valve to each header, so one well at a time can be routed to test.

Meaning

Gathers well flowlines into the production header and diverts one well to the test separator. Becomes production-manifold (slots = number of well inlets).

Variants

Three-header manifolds add an HP/LP or a gas-lift header
Multi-port selector valves (MSV) replace the valve pairs on newer designs
