About us
Founded in 1919, The Dallas Geological Society a constituent member of the Southwest Section of the American Association of Petroleum Geologists (AAPG) and, as a non-profit entity, strives to advance the professional interests of all geoscientists in the Dallas area, regardless of the geoscientific discipline they practice or the industry in which they serve.
​
The DGS currently serves more than 400 Dallas-area geoscientists. DGS cooperates with other geological organizations such as the Geological Society of America (GSA), the Society of Independent Professional Earth Scientists, the American Geophysical Union, the Society of Exploration Geophysicists, and the Dallas Geophysical Society to provide information and services to our members.
​
The Dallas Geological Society holds monthly luncheon meetings on the second Tuesday of the month (September through June) at Brookhaven College Geotechnology Institute. Luncheon talks vary on a wide range of topics from the world of petroleum geology, geophysics, or engineering.
​
The DGS International Committee is very active and holds monthly meetings on the third Wednesday evening of the month at Brookhaven Country Club in Farmers Branch. These meetings feature speakers on topical international issues (mainly petroleum exploration).
History of the Dallas Geological Society
The Fort Worth-Dallas Section [ancestor of our Dallas Geological Society] was one of six sections of the Southwestern Geological Society organized in Dallas in 1919 by Robert T. Hill, et al.
​
The Fort Worth-Dallas Section soon split up into the Fort Worth Section and the Dallas Section. DGS was known as the Dallas Section until 1924, when Southwestern Geological Society was disbanded and we then became Dallas Petroleum Geologists, affiliated with the American Association of Petroleum Geologists.
​
In 1945 we changed our name to Dallas Geological Society to conform to the nomenclature of societies throughout the world that were affiliated with AAPG.
