Hydrocarbon discoveries in frontier regions distant from shore and/or deepwaterare in the main marginal oil reserves lacking sufficient lease gas to satisfylocal power demand. System designs for offshore (subsea) power delivery havenot changed much over the past 50 years; gas and diesel are still the fuels ofchoice for power generation. Given today's volatile commodity market and theuncertainty surrounding climate change regulations developing thesegas-constrained reserves will require a more critical look at powerprovisioning options.
In general, these marginal reserves may support a 2-4 well project. And thebusiness economics dictate that the project's power demand is best served bylocal power generation as opposed to costly long-distance power transmissionfrom onshore.
In select regions of the world, the operator can look to renewables technology- wind, wave, current and ocean thermal energy conversion- for power generationwith no carbon footprint. This paper focuses in on a wave energy technologysolution for energizing a marginal oil field off the coast of West Africa. Itwill address the present status of the technology, recent technologicaladvances and future trends for this wave energy technology solution.
The outcome of this exercise indicates that in certain applications, waveenergy appears to be a cost-effective solution. A subsea asset without pumpinglargely has a peak end-load demand, so the intermittency of a renewable powerresource is tolerable. Where a pumping base load needs to be satisfied, theremay be a need for energy storage technology.
