While my system is chugging away on determining the LAT/LONG location for Kansas oilfields I thought I would post some information which surprised me.
There are over 50,000 wells in over 5,000 productive fields in Kansas. Admittedly quite a few of these are stripper wells (producing less than 500 barrels per year), but once again the sheer numbers would almost guarantee that some would be operating in T2k.
Great Information found here.
