Permian deals pass $400 billion since 2014 after Exxon mega-deal

| By Mark Young

Record-breaking productivity levels and low-cost production have seen the Permian Basin attract major M&A activity in the U.S. upstream sector.

In fact, following ExxonMobil’s $64.5 billion mega-deal to acquire Pioneer Natural Resources, Evaluate Energy data shows that the basin has now passed $400 billion in new deals agreed over the past decade.

For comparison, U.S. deals agreed without any Permian assets now account for $375 billion combined after Chevron’s own $60 billion mega-deal to acquire Hess Corp. was announced this week.

Deal values approach $100 billion in 2023 alone

Deals involving Permian assets account for 52% of all U.S. activity since the start of 2014 by value.

  • ExxonMobil’s acquisition of Pioneer means that 2023 is a record year for Permian-related spending, with deal totals approaching $100 billion for the first time.
  • The previous annual record in 2019 was also primarily down to one mega-deal that included Permian assets, when Occidental Petroleum won a bidding war with Chevron to acquire Anadarko Petroleum for around $55 billion.

Both years would have been below $40 billion in deals agreed without the two major deals boosting totals.

Production of over 6 million boe/d traded

The same ~900 deals that included Permian assets saw 6.1 million boe/d change hands since 2014*. This represents 40% of all U.S. production involved in M&A deals over the same timeframe.

We can attribute the large volumes traded in 2019 and 2023 to the Occidental/Anadarko (743,000 boe/d) and ExxonMobil/Pioneer (711,000 boe/d) deals, which alone comprise approximately half of the annual totals in those years.

Without those mega-deals, 2020 is arguably the “most active” year for Permian Basin M&A.

This was a year characterized by many mergers taking place across the U.S. for depressed values and low premiums.

Permian-related deals at this time included:

  • ConocoPhillips acquiring Concho Resources for $13.3 billion
  • Devon Energy acquiring WPX Energy for $5.7 billion
  • Chevron acquiring Noble Energy for $13.0 billion (although DJ Basin assets were the focus for Chevron)

Permian unsurprisingly dominates the top 10 U.S. deals by value in the past 10 years
