The Matterhorn Express Pipeline is fully subscribed after several producers in the Permian Basin added contracts in 1Q25, according to new regulatory data reviewed by East Daley Analytics.
EOG Resources (EOG), Diamondback Energy (FANG) and Anadarko Energy Services increased their firm transport (FT) contracts on Matterhorn from 4Q24, the latest Form 549D filings show. Form 549D is a quarterly report intrastate pipelines file with the Federal Energy Regulatory Commission (FERC) covering transportation and contracting activity.
The 1Q25 filing for Matterhorn lists 13 shippers, comprised mostly of Permian producers. Matterhorn now has a combined 2,061,000 MMBtu/d under firm contract, up from 1,865,000 MMBtu/d in 4Q24 and effectively matching its current 2.0 Bcf/d capacity. Most of the transportation contracts run through 2034.
East Daley maintains cleaned and updated data sets for 549D and other FERC filings as part of the FERC Products package. Clients can access the 549D contract data for Matterhorn and other intrastate pipelines in Energy Data Studio.
Among the updates, EOG doubled its FT capacity to 200,000 MMBtu/d from 100,000 MMBtu/d in 4Q24. FANG boosted its FT to 86,000 MMBtu/d from 10,000 MMBtu/d, replacing a contract that expired in Dec ’24 with a new deal that began in March. Anadarko Energy Services, the marketing subsidiary of Occidental (OXY), increased its firm contracted capacity by 20% to 120,000 MMBtu/d.
Operated by WhiteWater Midstream, Matterhorn had appeared to be running near capacity as early as late March when volumes to interstate pipelines first broke 1.5 Bcf/d, but a steady ramp into April pushed flows to a new maximum. Deliveries to interstates have consistently posted around 1.6-1.7 Bcf/d since April, according to pipeline activity monitored by East Daley (see figure). Matterhorn’s contracted quantities increased to its full capacity with Diamondback’s new contract beginning Mar. 1, and this contract likely played an important role in maximizing those volumes.
And Matterhorn still has room to grow. Updates to pipeline bulletin boards show Tres Palacios Gas Storage recently added a new Matterhorn interconnect. While no significant volumes have been nominated to this point, the inclusion of this meter highlights the growing value Matterhorn provides to the Gulf Coast markets.
Matterhorn is also expected to add 0.5 MMcf/d of capacity through new compression later this year. With Form 549D data showing the pipeline fully contracted currently, the pipeline will very likely be able to contract out all, or at least most, of the additional volumes from the compression expansion.
