From the Introduction
The purpose of this atlas is to provide a summary of research undertaken as part of a multiyear study (2009–2014) of Texas State Waters and the adjacent Federal Offshore continental shelf (i.e., near offshore waters of the State of Texas). The goal of the study was to assess and analyze existing data from historical hydrocarbon-industry activities in a regional transect of the Texas coast in order to verify the ability of Miocene-age rocks of the region to safely and permanently store large amounts of anthropogenic (industrial) CO₂.

The authors’ intent in producing this atlas is to provide a resource for exploring the geological CO₂ sequestration potential of the near offshore waters of the State of Texas by populating the atlas with both large-scale regional, qualitative and detailed quantitative information that can help operators quickly assess CO₂ sequestration potential at specific sites. This is the first comprehensive attempt to accomplish this goal in the near offshore of the Gulf Coast and United States.
