Solar Powered Technology Enhances Oil Recovery

mdsolar writes with this story of a company that uses solar energy to recover crude oil. Royal Dutch Shell has teamed with a sovereign investment fund from Oman to invest $53 million in a company that manufactures solar power equipment designed for increasing oil production. Glasspoint Solar Inc. installs aluminum mirrors near oil fields that concentrate solar radiation on insulated tubes containing water. The steam generated from heating the water is injected into oil fields to recover heavy crude oil. This concept of enhanced oil recovery. involves high pressure injection of hot fluids to recover heavy crude oil. The use of renewable energy like solar power makes great economic sense, as the fuel cost associated with this enhanced oil recovery technology is practically zero. Shell hopes to employ this technology in its oil fields in Oman. The company hopes to reduce greenhouse gas emissions associated with enhanced oil recovery operations. A large-scale successful implementation of this technology could be a game changer for major consumers like India and the U.S.. Both have substantial oil reserves, but are unable to tap them due to high costs involved in heavy oil recovery.

      Geothermal and hydrocarbon are not good bedfellows. Where you've got a high enough geothermal gradient for it to be a significant source of power, then you're going to be cooking your kerogens at depth shallow enough to have little prospect of encountering a trap, and they'll just sep out ot surface. Plus, you'd have a wider gas window and narrower oil window, and the oil is considerably the more valuable for export sales.

      Could you use directly geothermally-generated steam as a steam-flood source all in the one well? You'd need to rig your surface water injector on the injection well to higher pressures than for conventional water or steam injection (higher pressures cost more and wear out faster) but the production wells wouldn't need significantly different completion. Slugging of your steam flow from the geothermal source into the flood injection leg of the well would be an issue - potentially a big issue.

      What are the odds of the shape and size of your geothermal field being sufficiently close to power an outer ring of injection wells and efficiently steam-flood into the central few producers. It's not impossible, but it's also not terribly likely. Geothermal fields tending to be relatively large and disperses, but oil fields being sharply delineated by their original oil-water contacts (would you drill out in the water leg, except to provide pressure / waterflood support? Would you sign the AFE for subsidiary drilling centres, access roads etc for a 1/3 increase in well count (steam producer plus the regular injector - producer pair). You might make a case, but it's not going to be a high likelihood case.

    My understanding is that many oil wells vent large quantities of natural gas that are unprofitable to collect as a product, but could be used for on-site purposes. Solar panels are great if you have a ton of room, can keep them clean, and don't need continuous power, and want to appear "green." But for oil fields, using natural gas and processed fuels is the way to keep prices competitive.

      Another smart /. poster who exactly knows what the guys we talk about do wrong.

      So, lets summarize: the oil platforms using mirrors (not solar panels aka PV as you claim!) should use natural gas instead, because that would be cheaper. And you are surprised that the owner of the oil platform disagrees? Perhaps that particular oil field has no gas left? Or the gas is sold elsewhere? Hm, how does it come, what degree or secret insight do you have that you know more about "competitive oil prices" than one who actually is running an oil platform?

      The main reason the natural gas can't be sold commercially is that it's unpredictable. Some days, they extract a lot of high-quality gas, and other days they extract none, while still other days they might get something that's more toxic if burned.

      To use such gas for any commercial purpose would mean it needs to be reliable. Adding that reliability comes only at great expense.

      This solar process replaces up to order 80% of the fossil fuel that must already be employed to generate steam 'round-the-clock. There is also a gas-fired steam generator present to make steam at night and/or days with insufficient insolation, though they discuss on their website the notion that steam injection rates may vary - more during the day and less at night in order to increase the use of the solar-generated steam (to get up to the 80% level). Otherwise, the typical peak-rate to average-rate problem of solar power would make the amount more like 50% utilization absent additional hardware for steam storage.
