I've researched a bit more on drilling and I don't believe there is any
relation here.  There are 3 old wells in the 6 to 10 thousand foot range but
all are listed as wildcat dry holes in the state records.  The nearest
production appears to be about 15 miles northwest.
http://denr.sd.gov/des/og/maps/fallriver.gif  The quakes are in sec 35 of
11S 5E.  Looking at the USGS sites there seems to be a pattern of historical
activity roughly following the Nebraska South Dakota border and these would
fit that pattern
