Exterra Energy Inc. Houston, Texas, OTCBB : EENR is an emerging oil and gas exploration and production company based in Houston, Texas.

Exterra is primarily active in the Barnett Shale gas field in Texas and now holds an undivided interest in approximately 17,500 gross acres of leases in the Newark East (Barnett Shale) area with over fifty wells producing on the acreage.

The Company is also active in West Texas with twelve 10-acre oil and gas well sites in Pecos County.

The management team has successfully exploited oil and gas opportunities in the Newark East Barnett Shale gas field of North Texas for the past six years.

The Newark East Barnett Shale gas field is the largest producing natural gas field in the State of Texas.

The Barnett Shale is a geological formation consisting of sedimentary rocks of the Mississippian age in the state of Texas. The formation is estimated to cover 5,000 square miles in at least 17 counties in Texas. Some experts have suggested the Barnett Shale may be the largest onshore natural gas field in the United States. It is widely estimated to contain as much as 30 trillion cubic feet of natural gas.
