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.
Subsea High-Boosting Multiphase Pumps Increase Oil Recovery in Aging Field (Includes presentation slides)
Production from an offshore Angola field has been decreasing because of subsea pressure declines amid water-cut increases and limited gas compressor capacity. The development process leading to the selection of high-boosting multiphase pumps is described.
Nanotechnology for Oilfield Applications: Challenges and Effects
This paper presents a critical review of the recent literature to determine the status of research and development and field application of nanotechnology in the oil field.
Case History of Dehydration-Technology Improvement for HCPF Production in the Daqing Oil Field
High-concentration polymer flooding can improve oil-displacement efficiency but separation of oil/water mixture becomes more difficult because of emulsification. In this work, a case history of dehydration technology for HCPF production and lab investigation of emulsion behaviors are reviewed.
