There is disclosed a production manifold for use in the oil/gas industry, particularly for subsea use. Known manifolds suffer from a number of problems such as high capital cost, operating expenditure and the requirement of a dedicated test header. The present invention therefore provides an oil/gas production manifold (100) comprising first and second headers (145, 150) each of which is controllably communicable with at least one production well via control means (155, 160, 165), an outlet end of each header being connectable to a respective pipeline (280, 315), wherein the headers are connected to and communicable with one another by a pigging line (285).
