The fields are going to vary a lot. Some will be just fine, others not so much.
A low speed reciprocating engine engine can handle a lot of undesirables comparatively easy to some of the proposed processes or high-speed microturbine.
You can buy a engine that will run on straight crude oil (if it is light enough). We evaluated some of these for a remote facility needing a 30 MW power plant. In the end it was cheaper to build a basic topping plant, make our own diesel and have more efficient engines.
That's interesting. I've got 3 old wells in the back of the ranch that together might put a half inch a day into a 500 but they hang in there at about 180 MCF per day. I've got a couple of AJAX’s that are to small for the depths we're drilling now but would be perfect for use as generator motors. You have any experience with that type of a set up? Would like to power the Main ranch house (6500 sq-ft) the ranch Foreman's house and the guest house (those total less than 4,000 sq-ft) and it would be real nice if I could power some or all of the remaining 10 wells in the back. All are 228’s and 320’s with a 40 HP average. The new wells on the front of the ranch are all plunger lifts or flowing. Any input would be appreciated.
