Are the Brown Dense – Tuscaloosa Marine Shale Louisiana’s Future

by Kenneth E. DuBose on September 1, 2011

The Brown Dense and the Tuscaloosa Marine Shale continue to garner attention in Louisiana. Louisiana’s DNR Secretary Scott Angelle is the latest to comment on the potential of the two plays.

Louisiana Department of Natural Resources (DNR) Secretary Scott Angelle said today that the energy exploration industry has begun work on developing yet another new oil and natural gas shale play in Louisiana – giving the state one proven and producing shale formation and two that are being watched closely as the early stages of activity begin.

The potential new interest area, spanning portions of North Louisiana and southern Arkansas, is referred to as the “Brown Dense” or the “Lower Smackover,” and is believed to be a layer of limestone at the base of the Smackover Formation – which itself is a well-known formation that has long been a source for traditionally produced oil and natural gas in North Louisiana.

The “Brown Dense” joins the Tuscaloosa Marine Shale as the second half of Louisiana’s duo of dense rock plays believed to have the kind of production potential that has made shale plays such as Louisiana’s Haynesville and the Barnett and Eagle Ford Shales of Texas the new normal in energy exploration. The Tuscaloosa Marine Shale is believed to underlie much of Central Louisiana, with potential productive areas currently being explored from Vernon Parish to East Feliciana Parish.
