Currently fracking wells recover less than 10% of the oil in the North Dakota’s Bakken fields. Bismarck, North Dakota TV station KFYR aired a program discussing new technologies that might result in a major boost in the amount of oil recovered per well site. KFYR said that two technologies are under study.
Walking rigs – Used on Eco-pads that have several well bores at one location and can be moved from one well head to the next in a matter of hours instead of days.
CO2-enhanced recovery – The process has been used at other oil plays but would be new to the Bakken and could extend the life of wells there by 20 to 30 years.
