Random Look At An EOG Mandaree Well -- July 30, 2017

FracFocus. API: 33-053-03069. No frac data as of July 30, 2017, which means that no fracks have been reported to FracFocus since 2012.

Sundry forms: no evidence this well was ever re-fracked.

Neighboring wells: EOG fracked a number of great wells about this time and in July, 2014, asked to commingle oil from seven wells (#21003, #26768, #26789, #26777, #26778, #26779). The new wells were huge wells and there was a chance that there was a commingling error. (I doubt it; commingling errors are often corrected; unfortunately from the data one cannot say if there was a commingling error). Note: these are all short lateral wells.

#21003: also showed a jump in production but not as marked; it jumped form 1,500 bbls/month to 7,000 bbls/month; in both cases; the jump in production was sustained for about one year but at significantly lower production than the original jump.
