Abstract

A dual bore well jumper establishing fluid communication between a subsea well and a subsea flowline. The dual bore well jumper comprises a first pipe comprising a first pipe bore and a second pipe comprising a second pipe bore, the second pipe being located within the first pipe bore or side-by side with the first pipe. The dual bore well jumper further comprises termination couplings at each for establishing fluid communication with either the subsea flowline or the subsea well. The first and second pipe bores isolate fluid flow in the first pipe bore from fluid flow in the second pipe bore. The dual bore well jumper may optionally further comprise junction assemblies allowing a change in fluid flow direction. The dual bore well jumper may further optionally comprise a bore access module attached to a junction assembly for selective fluid communication with the first and second bores.
