Economics of Steam Generation for Thermal Enhanced Oil Recovery
The thermal-enhanced-oil-recovery (EOR) steam-generation projects in Persian Gulf oil fields are on such a large scale that they affect an entire country’s economic position. As such, the policies related to oilfield steam generation should be decided at the national level by use of the cost of the marginal fuel. This paper calculates the steam cost for three methods: once-through steam generator, once-through heat-recovery steam generator, and solar steam generator. Detailed performance and economic models of the steam-generation methods were created and used to calculate the levelized cost of energy (LCOE) and the fuel break-even (FBE) price. The environmental and economic burdens on the cost of steam generation are explored. The effect of fuel price on the cost of steam is also analyzed, with a focus on the marginal fuel price. Finally, the limitation of cogeneration in an isolated oil field, where the energy demand necessitates electricity-matched cogeneration, was analyzed. This limitation, along with the steam cost at the marginal fuel price, provides the decision maker with a steam-supply curve.
For the case analyzed in this paper, the cost of solar steam is lower than that of cogeneration or a simple boiler for fuel prices greater than USD 5/million Btu.
Water Desalination Applications in Shale-Gas and Polymer EOR Produced Waters
Oil and gas extraction using water has opened up new hydrocarbon resources. However they can produce four times more salty water byproduct than oil. Desalination in shale gas and polymer-flood EOR remain niche markets for lowering cost and improving production.
Bandwidth of Nanotechnology in the Oil Field Widens
Nanotechnology has great potential to reduce cost, increase production, and even improve the sustainability of E&P operations. But, where do we stand in terms of potential vs. reality? And, is the industry ready and willing to use the technology?
Chevron Sanctions St. Malo Waterflood Project
The project aims to contribute an estimated ultimate recovery of more than 175 MMboe from one of the company’s signature deepwater projects in the US Gulf of Mexico.
