Utica Oil: EOG’s New Downspacing Test Came on With 1,108 bbl/d

EOG Resources’ five-well, 700-ft downspacing Utica oil test came on with more than 72,000 bbl in its first 13 days online, according to new data from Ohio state files.

The pad, Shadow CBR07 in Carroll County, is near EOG’s four-well, 1,000-ft spaced Timberwolf CBN16, which came online in August 2023.

Shadow’s five wells’ total 72,022 bbl, averaging 1,108 bbl/d, according to Ohio Department of Natural Resources well files.

At Timberwolf, the first three of its wells produced 137,632 bbl in their first 37 days, averaging 1,239 bbl/d each. A fourth well was turned into sales four months later for 658 bbl/d its first three months.

Through June 30, Timberwolf has produced 919,551 bbl, averaging nearly 740 bbl/d per each of the four wells in their combined 1,243 days online.

EOG is expected to provide an update on the Shadow pad and other Ohio results during its third-quarter earnings call in the coming weeks.

The operator’s roughly 445,000 net acres, which are more than 90% HBP in the Utica’s volatile oil window, span a roughly 140-mile north-south stretch through eastern Ohio. EOG also owns the minerals under 135,000 of the net acres.

Encino’s 1,587 bbl/d Sproul wells

Six of Ohio’s Top 10 oil wells in the second quarter were made by privately held Encino Energy, including its four Sproul TC RSH pad wells in Tuscarawas County, according to the Ohio DNR.

In their first 80 days online, the wells surfaced 507,712 bbl, averaging about 1,587 bbl/d each.

Separately, privately held Encino’s new four-well Sparkman GY CEN pad in Guernsey County made 383,773 bbl in its first 78 days, averaging 1,230 bbl/d each.

Infinity turned to sales the state’s No. 9 well also: Casper #1HU with an 88-day average of 1,112 bbl/d.

The four-well Casper pad’s two additional wells—Casper #3HU and #7HU—brought the pad’s first-88-day average to 1,085 bbl/d per well, according to the Ohio DNR.

The Guernsey County well produced 1,158 bbl/d in the quarter’s 91 days, according to the Ohio DNR well files.

The #1H had already been online for 42 days, making 54,604 bbl in February and March. Its first-133-day output through June 30 was 159,980 bbl, averaging 1,203 bbl/d.

It and the #3H and #5H in the three-well Slabaugh pad produced 414,711 bbl in their combined first 395 days online, averaging 1,050 bbl/d each.

Also in Guernsey County, Ascent brought on its four-well Caston NE LND GR pad in the second quarter, producing 1,117 bbl/d per well in their first 70 days online.

Its Posey C UP GRS #5H produced an average of 1,030 bbl/d during the 91 days.

Separately, Gulfport Energy reported this summer it turned to sales a four-well Utica test of the oil potential in its westernmost Ohio acreage. Production data has not yet been reported.
