Abstract: A system for utilizing excess heat during a subsea field operation can include a subsea manifold configured to transfer a subterranean resource to a pipeline located subsea, where the subterranean resource radiates the excess heat after being transferred out of the subsea manifold. The system can also include a subsea power generation system that receives the excess heat from the subterranean resource as the subterranean resource is transferred from the subsea manifold to the pipeline, where subsea power generation system uses the excess heat to generate electrical power.

Abstract: A system for utilizing high pressure subsea reservoir energy to support low-pressure subsea production wells can include a high-pressure subsea well in production, a first subsea piping that receives a high-pressure fluid of the high-pressure subsea well, a low-pressure subsea well in production, and a second subsea piping that receives a low-pressure fluid of the low-pressure subsea well. The system can also include a subsea regenerative turbine that receives the high-pressure fluid of the high-pressure subsea well from the first subsea piping. The system can further include a subsea pump assembly that operates using energy generated by the subsea regenerative turbine, where the subsea pump assembly helps move the low-pressure fluid of the low-pressure subsea well through the second subsea piping.
