WAHA Natural Gas Price

Most Permian gas is produced as a by-product of crude oil drilling (associated gas). Because operators are primarily chasing oil, gas keeps flowing even when there is nowhere profitable to sell it. The result is persistent local oversupply: the basin produces more gas than its takeaway pipelines can carry, so the marginal molecule has to be priced low enough to clear.

This is the Henry Hub-to-Waha basis: the difference between the national benchmark and the local Permian price. When pipelines have spare room, the basis is modest. When they are full, Waha can collapse to a deep discount, and at times the gas has traded at negative prices, meaning producers effectively pay to have it taken away rather than flare or shut in production.

Major takeaway projects such as Gulf Coast Express, Permian Highway, Whistler and the Matterhorn Express line have each, on start-up, relieved congestion and lifted Waha prices back toward Henry Hub. As production growth catches up to that new capacity, the basis widens again. Waha therefore tends to trade in a sawtooth pattern tied to the timing of pipeline expansions versus drilling activity.

Maintenance events compound this. When a single large pipeline goes down for planned or unplanned work, gas backs up in the basin almost immediately, and Waha can swing several dollars within a single trading session. For anyone modeling Permian economics, the takeaway schedule matters as much as the supply-demand balance.

Permian upstream operators use Waha to value the gas stream attached to their oil production and to decide whether to curtail. Midstream and pipeline shippers track the Henry Hub-Waha basis to value firm transportation capacity. Gas marketers and traders treat the basis itself as a position. Increasingly, LNG and petrochemical buyers on the Gulf Coast care about Waha because Permian gas feeds the export and industrial corridor downstream.
