A subsea manifold layout interconnects subsea pipelines that extend beside each other to convey hydrocarbon production fluids in use. Each of the pipelines has an in-line manifold portion that is apt to be installed with the pipeline as an in-line accessory structure lowered with the pipeline from the surface, for example using S-lay, J-lay or reel-lay techniques. Thus, the in-line manifold portions of the respective pipelines are structurally separate from each other. Bridging pipes complete a subsea manifold structure having two or more of the in-line manifold portions, providing for production fluids to flow between the pipelines via the manifold portions of the respective pipelines.

An apparatus includes a subsea flow line and a two stage heat exchanger. The subsea flow line communicates a process flow that is associated with a subsea well, and the heat exchanger transfers thermal energy between the process flow and an ambient sea. The heat exchanger includes a primary circuit in communication with the flow line to transfer thermal energy with the process flow; and the heat exchanger includes a secondary circuit in thermal communication with the primary circuit to transfer thermal energy with the primary circuit.

A rigid valve block body and a method for determining fluid flow direction are disclosed. The valve block body includes a first fluid inlet and a further fluid inlet at opposed sides of a rigid valve block body. A first fluid outlet of the valve block body and a further fluid outlet of the valve block body are disposed in a spaced apart relationship. A first V-shaped fluid communication passageway comprises two passageway portions each extending within the valve block body from a first common root region proximate to the first fluid inlet. A further V-shaped fluid communication passageway comprises two further passageway portions each extending within the valve block body away from a further common root region proximate to the further fluid port. An end region of each passageway portion of the first V-shaped fluid communication passageway meets an end region of a respective passageway portion of the further V-shaped fluid communication passageway proximate to a respective fluid outlet.

A global fluid identity repository is used to maintain and manage fluid characterization data for various fluids utilized in the oil & gas industry, e.g., reservoir fluids within subsurface formations. Tracking and notification services may be utilized to track changes made to a global fluid identity, e.g., changes in fluid sample and/or experiment data for a fluid, and automatically generate notifications when downstream data such as fluid models and/or simulation results become stale as a result of these changes.

A subsea equipment includes two manifolds for fluid import and export from oil wells. The first and second manifolds are arranged in parallel and are interconnected by a jumper. The first manifold includes all equipment for field flow control, such as, for example, selection valves, actuators or robot for remote operations and mandrels for connection to the Christmas trees. The second manifold includes only block valves and mandrels for future interconnection or interconnection to the first manifold.
