A historical review of induced earthquakes in Texas
In Texas, earthquakes have occurred in close association with activities accompanying petroleum production since 1925. Here we develop a five-question test to categorize individual events as “tectonic,” “possibly induced,” “probably induced,” or “almost certainly induced.” In Texas, the probably induced and almost certainly induced earthquakes are broadly distributed geographically—in the Fort Worth basin of north Texas, the Haynesville Shale play area of east Texas, along the Gulf Coast in south Texas, and the Permian basin of west Texas.
