In December, Antero Resources announced a deal to sell its Ohio Utica assets to a partnership of Northern Oil & Gas (NOG) and Infinity Natural Resources (INR) for $1.2 billion in cash (see NOG & INR Partner to Buy Antero Resources’ Ohio Utica for $1.2B).

The midstream (pipeline) part of the deal includes approximately 141 miles of wholly owned midstream gathering lines and approximately 90 miles of water lines. Yesterday, NOG and INR announced that they are tweaking the arrangement, with INR boosting its ownership share in the deal from 51% to 60%.

Midstreamer Williams Rumored to be Interested in Upstream Again
February 9, 2026April 13, 2026

Pipeline giant Williams Companies is exploring a strategic return to natural gas production to create an integrated “one-stop shop” for AI hyperscalers and data center operators. By potentially acquiring upstream assets to complement its 33,000-mile pipeline network and new power-generation projects such as the Socrates facility in Ohio, Williams aims to offer a turnkey energy solution that bypasses traditional grid constraints. This move toward a “bundled” model reverses a decade of industry specialization, positioning the firm to capitalize on the massive power demands of artificial intelligence. Investors are watching for official confirmation during the company’s 2026 analyst day tomorrow. Read More “Midstreamer Williams Rumored to be Interested in Upstream Again”

Analysts Speculate About the Future of Coterra’s Marcellus Assets
February 4, 2026February 4, 2026

Yesterday, MDN brought you the big news that Devon Energy is buying out and merging with Coterra Energy, paying $21.4 billion in Devon stock (see Devon Energy Buying Coterra Energy for $21.4B in All-Stock Merger). The focus of the merger is the two companies’ complementary acreage in the oil-rich Delaware Basin, a subbasin in the Texas Permian. Analysts are now discussing what a post-merger company will look like in terms of assets. Will the combined company (keeping the Devon name) keep or sell its prolific Marcellus assets in Susquehanna County, PA? Read More “Analysts Speculate About the Future of Coterra’s Marcellus Assets”

Coterra Energy CEO Tom Jorden’s “Golden Parachute” Worth Millions
February 4, 2026February 4, 2026

Not that he isn’t already a very rich man, but Coterra Energy CEO Tom Jorden stands to rake in an additional $6 million to $9 million (possibly much more) from a “golden parachute” if the proposed merger between Coterra and Devon Energy goes through. Based on the reports following the merger announcement between Coterra and Devon, Coterra’s upper management (in particular, Jorden) is protected by substantial “golden parachute” (change-in-control) agreements. These agreements were specifically updated just before the deal was made public to ensure executive retention and fair treatment during the transition.

Devon Energy Buying Coterra Energy for $21.4B in All-Stock Merger
February 3, 2026February 3, 2026

As rumored last week, Devon Energy and Coterra Energy are merging to create a shale drilling giant. The headlines say it’s a “$58 billion deal.” Beneath the headlines, you’ll learn that Devon is buying, Coterra is being acquired, and that Devon is paying (in stock only) $21.4 billion for Coterra Energy. The two companies combined into one will be worth (market capitalization) around $58 billion, which is where that headline number comes from. The merger is expected to take place in the second quarter of this year. The new company will keep the Devon Energy name. Coterra will be no more, just like Cabot Oil & Gas was no more after it merged with Cimarex Energy to form Coterra in October 2021 (see Cimarex Takes Over Cabot, Merged Co. Called “Coterra Energy”).

January 30, 2026January 30, 2026

All the major media outlets (Reuters, Bloomberg, Financial Times) are reporting that a merger announcement between Coterra Energy and Devon Energy is very close, likely to happen next week, according to sources “familiar with the discussions.” MDN reported on the rumors of a potential merger earlier this month (see Rumor Mill Lights Up: Coterra Considers Merger with Devon Energy). The unnamed sources say the merger will be billed as a merger of equals. Which is rubbish. You’ll know which company is doing the buying when it’s announced which CEO and board will run the merged entity. Read More “Coterra/Devon $60B Merger Likely to be Announced Next Week”

Rumor Mill Lights Up: Coterra Considers Merger with Devon Energy
January 16, 2026January 16, 2026

The rumor mill is in overdrive today with news that Coterra Energy is in serious talks with Devon Energy exploring a potential merger “that would be among the biggest oil and gas deals in years.” While the primary driver of this deal is gaining massive scale in the Permian Basin, Coterra’s substantial Marcellus Shale assets in northeastern Pennsylvania (NEPA) are a major point of speculation for analysts and investors. It appears possible (likely?) that a combined company would sell off the PA Marcellus assets. Read More “Rumor Mill Lights Up: Coterra Considers Merger with Devon Energy”

The bidding war for Ascent Resources continues and gets more complex.

Quantum Capital Selling Cogentrix Gas-Fired Plants for $4 Billion
January 6, 2026January 6, 2026

In August 2024, Quantum Capital Group entered into an agreement to acquire Cogentrix Energy, an independent power producer, from another investment firm (Carlyle) for $3 billion (see Quantum Capital Buying Cogentrix Gas-Fired Plants for $3 Billion). The Cogentrix portfolio comprises 5.5 gigawatts of natural-gas-fired power plants located throughout PJM (the M-U region), ERCOT (Texas), and ISO-NE (New England).

Yesterday, Vistra Corp. announced it is buying the Cogentrix Energy plants from Quantum in a deal worth $4 billion. Not a bad deal for Quantum—buy and hold Cogentrix for 15 months, then flip the assets for a cool $1 billion profit. Read More “Quantum Capital Selling Cogentrix Gas-Fired Plants for $4 Billion”
