EON Resources Inc. Announces Results of Engineering and Petrophysics Study in Its South Justis Unit
Rhea-AI Summary
EON Resources (NYSE American:EONR) reported results of engineering and petrophysical studies on the Blinebry interval in its South Justis Unit in Lea County, New Mexico. According to EON, horizontal development of this Yeso-formation interval is estimated to yield 13 million barrels of recoverable oil across 21 planned horizontal wells, with peak field production targeted at 10,000 BOPD in 2028.
The company’s in-house team, which designed a 92-well, $330 million, 45-million-barrel San Andres program in the Grayburg-Jackson Field, concluded that Blinebry rock quality supports higher per-well IP and EUR than San Andres. EON estimates average Blinebry EUR of 650,000 barrels per well (range 245,000–1,250,000 barrels), at an average $4.7 million drilling cost per well and anticipated initial rates of 700–1,100 BOPD. The study highlights 200 million barrels of original oil in place, heterogeneity and poor legacy waterflood performance by ARCO as factors making the reservoir well-suited to modern multi-frac horizontal development. EON plans next to decide whether to self-fund or pursue a farmout partner for potential development beginning in 2027.

Anticipated 13 million barrels of oil recoverable at 10,000 BOPD Peak Rate with an average 700 BOPD per well with 21 wells
HOUSTON, TX / ACCESS Newswire / July 27, 2026 / EON Resources Inc. (NYSE American:EONR) ("EON" or the "Company") is an independent oil and gas company operating in the prolific Permian Basin, the highest oil and gas producing area in the United States. EON operates two fields with approximately 20,000 leasehold acres producing over 1,100 barrels of oil per day ("BOPD").
The Company today announced the same in-house technical team that identified the San Andres formation potential in our Grayburg-Jackson Field in Eddy County, New Mexico, which resulted in a 92-well,
Background
The South Justis Unit was acquired on June 8, 2025. The unit comprises 5,360 contiguous leasehold acres, 97 producing wells and 85 injection wells for a total of 182 wells. EON estimates that through horizontal drilling it can develop the unit with recoverable reserves in the range of 13 million barrels of oil from the Blinebry Interval, which is within the Yeso formation.
Atlantic Richfield Company ("ARCO") developed the South Justis Unit into a multi zone waterflood with mixed results. The lack of continuity between wells is a key positive contributing factor to why horizontal drilling holds much more promise, as horizontal wells connect the formation across a large area that were previously untapped and disconnected.
EON's South Justis Unit technical study found the Blinebry interval to be significantly better than the prolific San Andres formation from state-of-the-art petrophysical analyses on a per well initial oil production and per well estimated ultimate oil recovery (EUR) basis.
This same analysis technique was recently confirmed with field tests in EON's Grayburg-Jackson field, which has now been given a green light for the horizontal drilling of 92 wells in the San Andres formation.
The Blinebry interval is a major tight-carbonate oil and gas zone located primarily on the northwest shelf of the Permian Basin in Southwest New Mexico, largely in Lea County. This formation is famous for producing "sweet spot" high gravity oil and gas.
"We anticipate 21 high-quality horizontal wells capable of producing 700-1100 BOPD, each at an average estimated cost of
EON plans to next evaluate whether it should "go it alone" or seek a farmout drilling partner for development of the South Justis Unit as it has successfully done previously in the Grayburg-Jackson Field, so development can begin in 2027. The Company estimates ultimate recovery to average 650,000 barrels per well, or 13 million barrels across 21 wells, at peak production of 10,000 BOPD in 2028.
"The South Justis Unit has significant horizontal well potential, which was too small for major players in the horizontal well realm, but not for EON," Mr. Caravaggio added. "We will continue to uncover opportunities like the horizontal drilling potential at our Grayburg-Jackson Field and our South Justis Unit. The Permian Basin, with its stacked pay zones, continues to be the gift that keeps on giving."
Key South Justis Unit Study Conclusions
Large remaining Oil in Place of 200 million barrels:
A multi-zone carbonate with under recovered oil reserves and a failed waterflood by ARCO
Substantial reserves remain best recovered utilizing muti-frac, long lateral, horizontal wells
The rock properties that doomed the waterflood by ARCO
High heterogeneity
Poor lateral connectivity
Are ideal for exploitation by horizontal multi-frac wells
Additionally, the Blinebry interval permeabilities are many orders of magnitude better than most Permian shale developments which will result in:
High Oil IP's (initial production) and
Higher EURs (Expected Ultimate Recovery)
The Blinebry interval being the zone of interest at about 5,100 ft Measured Depth (gross thickness of 400 - 500 ft)
Expected EURs dependent on lateral length and frac density
Minimum EUR per well of 245,000 bbls of oil
Max EUR 1,250,000 barrels of oil
Average EUR per well of 650,000 bbls of oil
