RE: RE: RE: RE: RE: RE: great info siteIts a 912 jack with the first number always referring to the torque rating of the pump. In this case 912,000 lbf-in. The bigger the number the more "weight" the pump can move. The total weight on the jack is a combination of the weight of the rods, friction and of course the fluids above the jack. So Kahn's statement of pumping more oil should be pump more fluid to be most accurate.
Don't forget that water is also a major component of every one of these Bakken wells so far with one of the highest water producers being the Shell 9-17 well. After all the hype on huge volumes lifted to date the well was shut-in to change the pump as it has made nothing but water other than 324 m3 of oil produced in March 2011. Just to be clear it has not reported any oil production after the first month and has made nothing but 500-600 bbl/d of water ever since. At that depth and water volumes the 912 is required to lift all of that fluid. Will the oil ever come? The Nexen well offsetting GSY at 1-28 made 20 bbl/d of oil in its first full month of production. That simply isn't good enough for the amount of capital being spent. There is a long way to go on this play before anybody hits the big payday.
Buyer beware on this stuff, none of the wells have made much oil so far.
