EnerVest Likes Clinton Sandstone “Utica-lite” Oil Wells in OH
Once upon a time the Clinton Sandstone layer was the most drilled rock layer in Ohio. Then the Utica/Point Pleasant came along and it seemed as if everybody forgot about the Clinton. Previously the Clinton was drilled vertically, or conventional-only. But what if you drilled the Clinton horizontally, like you do in the Utica? You might get a “Utica-lite” well, as we commented a year ago (see Ohio Clinton Sandstone Horiz Wells on the Increase – Utica-Lite?). Last year MDN told you that EnverVest, among others, was experimenting with horizontal drilling in the Clinton Sandstone. According to drillers who are experimenting in the Clinton, drilling a horizontal Clinton well is anywhere from 3-10 times more expensive than a conventional well, but it produces anywhere from 7 to 20 times more oil, which is typically what they’re drilling for in the Clinton. EnerVest has drilled seven horizontal Clinton wells and is extracting 1,100 barrels of oil per day from those seven wells. Here’s more details shared by EnevVest at a recent OOGA meeting about their Clinton Sandstone efforts…

Rex Energy, a Marcellus/Utica driller based in State College, PA, filed its fourth quarter and full year 2015 financial and operating update yesterday. Although production was down in 4Q15 compared with 3Q15 and 4Q14 (4% and 5% respectively), overall production for Rex for all of 2015 increased 27% over 2014.

As we’ve previously noted, Rex entered a joint venture deal to get money to keep drilling in the Marcellus and Utica (see
