Probable Production Induced Subsidence, Fault Reactivation, and Wetland Loss in the Gulf Coast Region

PowerPoint Presentation: download the presentation in Microsoft PowerPoint format PowerPoint Presentation - 14.8MB PPT "Probable Production Induced Subsidence, Fault Reactivation, and Wetland Loss in the Gulf Coast Region" summarizes the significant results of a U.S. Geological Survey study conducted recently in Louisiana and Texas. The study results and their implications with regard to coastal restoration were presented to government agencies, academicians, consultants, and the general public in Lafayette, Baton Rouge, and New Orleans, Louisiana the week of April 7, 2003.
