Subsidence profiles across 29 oil and gas fields in the 12 200 km2 Houston, Texas, regional subsidence area, which is caused by the decline of ground-water level, suggest that the contribution of petroleum withdrawal to local land subsidence is small. In addition to land subsidence, faults with an aggregate length of more than 240 km have offset the land surface in historical time. Natural geologic deformation, ground-water pumping, and petroleum withdrawal have all been considered as potential causes of the historical offset across these faults. The minor amount of localized land subsidence associated with oil and gas fields, suggests that petroleum withdrawal is not a major cause of the historical faulting. -from Authors
