Is your SWD well inside a Seismic Response Area?

Data as of 2026-04-18.

The pain

Three active SRAs carry specific injection-pressure and volume caps

The Texas Railroad Commission issues Seismic Response Areas — geographic zones where elevated induced-seismicity risk triggers specific injection restrictions on nearby disposal wells. Three are active as of 2026: Gardendale, Stanton, and Northern Culberson-Reeves. Each SRA carries a controlling TRC order with the precise restrictions.

For permit work, the question is rarely subtle: either a well sits inside an SRA or it doesn't. But the operational effect is large. SRAs can cap daily injection volumes, require pressure-test frequencies, and trigger monitoring obligations that don't apply to wells a mile outside the boundary.

How PermianIQ helps

  • Every well on the PermianIQ map carries an SRA flag and the controlling order reference
  • SRA boundaries rendered as map overlays with the order text linked
  • Cross-referenced with TexNet seismic events for 12-month context
  • Used for permit narrative, lease evaluation, and post-injection monitoring planning

Frequently asked

How many SRAs are active in Texas right now?
Three as of 2026-04-18: Gardendale, Stanton, and Northern Culberson-Reeves. The TRC updates the list as seismic conditions warrant; verify directly before relying on it for a filing.
What restrictions apply inside an SRA?
It varies by SRA. Common elements: daily injection volume caps, maximum surface pressure limits, monitoring and reporting cadence, and in some cases shut-in triggers tied to specific seismic events. The controlling TRC order for each SRA spells out the exact limits.
Does being adjacent to an SRA affect my well?
Formally, only wells inside the SRA polygon are subject to the SRA order. In practice, proximity increases TRC scrutiny — especially within a few miles — and should be addressed in permit narratives even if the well is technically outside.
Where does PermianIQ get SRA boundaries?
Public TRC-published shapefiles. We update when the commission publishes changes. 'Data as of' date is shown on every view.
