Historical subsidence rates calculated by the National Geodetic Survey
Detailed Description
Historical subsidence rates calculated by the National Geodetic Survey from repeat leveling surveys at benchmarks along Bayou Lafource between Raceland and Grand Isle. Shaded areas delineate approximate productive boundaries of nearby oil-and-gas fields; dashed vertical lines show projected intersection with subsurface faults. Abbreviations: mm/yr, millimeters per year; km, kilometers.

Induced Subsidence Related to Hydrocarbon Production - Subsidence and Wetland Loss Related to Fluid Energy Production, Gulf Coast Basin
One of the primary goals of this project was to test the hypothesis that long-term, large-volume hydrocarbon production along the Gulf Coast resulted in land-surface subsidence, reactivation of deep-seated faults, and wetland loss in Texas and Louisiana.
