Guys at Shell tell me their recovery rate was internally reported to be in the mid-60 per cent range (they pioneered the area, in a nearby play) but when they did their detailed testing after the first pay zone had been developed, they found zero trace of hydrocarbons. That means they got ALL of it out.
Shell's recovery rates are proprietary, as is the technology (or more likely the many combination of technologies) they used; but this is the word around the oil patch in Calgary.
By the way, the weird news related to this is that the president of Pan Orient, the company that owns more than 70 per cent of DWOG's development partner Andora, has pulled up stakes and left Alberta to go live in Thailand. Looks like POE boss Jeff Chisholm is enjoying the good life in Bangkok even before the first drop of oil comes out. He must be really confident about the success of the reservoir!
