Title: Louisiana Tuscaloosa Versus Southeast Texas Woodbine: ABSTRACT

Author(s): Frank W. Harrison, Jr.

Article Type: Meeting abstract


The deep Tuscaloosa play extending across south-central Louisiana has resulted in the recent discovery of large gas reserves. This same downdip lower Upper Cretaceous interval, known as the Woodbine in southeast Texas, extends into Texas across Newton, Jasper, Polk, and Tyler Counties. Although well control is sparse through this interval in southeast Texas, available data suggest a different depositional and structural setting for the lower Upper Cretaceous interval. No thick units of sands are within the interval, and most of the production has been found in stratigraphic traps exhibiting thin sands, as in the Seven Oaks field.

Subsurface studies of the lower Upper Cretaceous interval across south-central Louisiana and into southeast Texas indicate it is unlikely the Louisiana Tuscaloosa play will extend into the southeast Texas area. However, there is sparse downdip control in Texas south of the Lower Cretaceous shelf edge and it is, therefore, possible that some sands have been deposited subparallel to the shelf. The best area to explore for this possibility would be south of the 1,000-ft Tuscaloosa or Woodbine isopachous contour which extends across southeast Texas.
