Side by side - Top oil and gas producing wells in the Utica Shale in Q2 2014

There are many ways of analyzing and comparing oil and gas production of wells in the Utica / Point Pleasant Play in Ohio.
Maps clearly show the general separation of higher oil production to the west and higher gas production to the east. Surprisingly, some Noble County wells made it on both maps.

Average production/day one measure
Average production/day was chosen as the yard stick here. We could have selected total production in the quarter but that would fail to recognize highly productive wells that were in production for just a short time during the quarter. Avg production/day can skew the data to the newer wells that will have higher initial production so there isn't a perfect measure.

Data mounts
Each quarterly report gives us more production and decline curve data for wells. Such data will be a good measure, though even this can be skewed by unique processes used to drill, complete and exploit individual wells. As operators learn more we should see better production curves from adjacent wells. Though even then, there will be a lot left to interpretation. As has been said many times before, we are still in the early days of exploiting and understanding the play.

Map left - Bottom hole locations for wells that averaged more than 150 barrels of oil/day in Q2 2014 (65 wells)
Map right - Bottom hole locations for wells that averaged more than 5,000 Mcf/day of natural gas in Q2 2014 (63 wells). Production cutoffs were somewhat arbitrary and designed to show a good sample of data. All data comes from the Ohio DNR. See page here which includes a note on wells potentially not included in the maps below.
