Temporary pumping system
I would like to intall a temporary pumping system inside 9-5/8-inch ID casing that can produce 400 gallons per minute with 1000-1100 feet of lift to ground surface.  The system needs to work for 2 months and there is no electrical service at the site.  I am tending away from an electric submersible because of cost, the possible requirement for two pumps in tandem, and the need for generators at the site.  I'm not sure about air-lifting because there will be only 100-200 feet of subergence (prior to pumping).  I would appreciate suggestions on ways to proceed.  Thanks.
