Abstract

The present invention relates to a header configuration block for a hydrocarbon well comprising a header configuration block housing having a plurality of transversal bores each in fluid connection with a discrete longitudinal main bore. At least one cut off valve is located in each transversal bore. A first connecting surface is parallel to and similar with a second connecting surface, whereby the first connecting surface and the second connecting surface are adapted to be connected to at least one further similar header configuration block. The invention also relates to a manifold branch configuration block and a well fluid manifold assembled of header configuration blocks, branch configuration blocks and flow line configuration blocks.
