Southwestern Energy’s talented geoscientists are guided by experience, vision, and an innate curiosity to explore and identify new natural gas prospects. Exploring an area of interest begins with a thorough analysis of the existing data including studies of the surface geology, existing well log information, production information and gas and oil shows from drilling. We also analyze 2-D and 3-D seismic data as well as gravity, magnetic, and other remote sensing statistics to help guide us in determining if the potential for gas or oil exists. A structure map of the subsurface is also created along with other geological and geophysical maps. These maps help determine if there is potential for trapped oil or gas in the formation. The geologists works within a team of geoscientists, engineers, landmen and others to incorporate all of the expertise in selecting the best location to drill a well to test the prospect. Geologic surveys and mapping, seismology and exploratory drilling are all used to explore for natural gas reserves. By using the most up-to-date technology, we can more accurately locate and assess underground reservoirs with minimal impact on the surface.
3-D Seismic
Southwestern Energy’s geologists evaluate and map the surface topography, while our geophysicists use the latest 3-D seismic techniques and processing to create detailed images of the subsurface layers. This amazing technology helps us know where to drill for natural gas by using sound waves to create 3-D maps of rock formations lying thousands of feet below the earth’s surface. Seismic data is invaluable when exploring the subsurface as it paints a realistic picture of the complexity and depth of the geology below. The development of seismic imaging in three dimensions has greatly changed the nature of natural gas exploration, and there are many benefits of this process. Exploration teams can now more easily identify natural gas prospects, place wells more effectively, reduce the number of dry holes drilled, reduce drilling costs and cut exploration time. |
