$this->bbcode_second_pass_quote('Plantagenet', 'H')as anyone mentioned the huge new oil discovery at Smith Bay, Alaska?
Caelus Energy is now reporting they've found 6-10 billion barrels of oil.
Caelus has made some very big claims. See
https://www.adn.com/business-economy/energy/2016/10/04/caelus-claims-world-class-offshore-arctic-oil-discovery-that-could-among-alaskas-biggest/However, I would hold off on the celebration for a bit. It may work out for them, but they have made some big extrapolations, based on fairly skimpy data. Most importantly, while they have drilled a couple of wells, so far
they don't have a single flow test. They recently gave a fairly detailed public presentation. The only data they currently have are logs and some side wall cores from their wells, and seismic. The rocks are very tight, with average porosity around 15%, and average perm around 4 millidarcy. They think the oil is 43 API, but that is based on gas chromatography of extracts from their SWC. They think fracking will help them produce. This is a strat trap, so everything is based on what they see in those 2 wells, together with extent based on seismic signature. The reservoir is in turbidite sands of the Torok Fm, which can sometimes be complex. This discovery is in shallow water offshore in Smith Bay, and there will be some very difficult engineering and environmental issues to overcome.
Keep in mind that a company the size of Caelus does not have either the money nor the in-house engineering expertise to bring this to development. They are obviously looking for partners, preferably one of the larger oil companies like BP or ConocoPhillips to come in as a partner. Hence Caelus has a large incentive to put the best possible spin on the data they have. It certainly could work out to be as big as they think, but they are a long way from demonstrating that. So at this stage a good deal of caution and skepticism is called for.
Upthread someone noted that ConocoPhillips has also announced a discovery. See
https://www.adn.com/business-economy/energy/2017/01/13/conocophillips-announces-alaska-discovery-with-daily-production-potential-of-100000-barrels/I feel a bit more warm and fuzzy about the Conoco discovery. They have actual well test results. It is onshore and somewhat closer to existing infrastructure than the Caelus discovery. It is in topsets of the Nanushuk Fm. And Conoco is a large and well established N Slope producer, and doesn't need to spin it to attract partners.
Stay tuned, as it will be very interesting to see how these discoveries play out.
