Please join us for a luncheon and presentation:

"A New Method to Identify and Correlate the Pennsylvanian Atoka Formation Subdivisions in the Surface Outcrops of the Boston Mountains, Arkansas" with Brent Boyd

Lunch will be served at 11:30 and presentation will begin around 12:00

Abstract

In the surface geological map of Arkansas, everything in the Boston Mountains of the Ozarks, from Fayetteville to Ft Smith, is labeled as Atoka Formation. However, the petroleum industry has subdivided the Atoka Formation in the subsurface of the Arkoma Basin. Atoka gas producing intervals such as Dunn A, Casey, or Orr can be correlated across the basin in the subsurface, yet the correlations have never been carried in a regional sense to the Atoka surface outcrops. This presentation will demonstrate how the combination of LiDAR and well logs can correlate and map the Atoka subdivisions in the Boston Mountains. Now the petroleum industry and go and touch the reservoir rocks in addition to mapping them in the subsurface.

Bio

Brent Boyd received his Bachelor of Science in Geophysics from Texas A&M University in 1985. He spent 35 years in oil and gas exploration for Atlantic Richfield, Anadarko, and Oxy. He retired from Oxy in Houston in 2020 and moved to Fayetteville Arkansas the next year. Most recently, he earned his Master of Science in Geology from the University of Arkansas in 2025. This presentation is his thesis work for his degree.
