Here are a few of the decline curves plus the bottom hole pressure survey that shows the actual hit in real time. The well with the pressure survey (Wakeman) actually got “bumped” (our term) from a November, 2015 frac that caused a loss in oil production (30 BOPM to 5 BOPM) (See decline curve), then “hit” in May, 2016 which killed it. It has partially recovered.
The King-Vieth well was just hit again by another frac, so May oil and gas will be down and water up.
The Perdue 17-2 has seen an increase in production due to the hit. But, as noted, the expenses have skyrocketed due to the frac hit (We had frac sand in the pump the last time it was pulled).
