We are an independent energy company engaged in the acquisition, exploration, development and production of domestic onshore crude oil and gas reserves. Our oil development activities are primarily focused in our waterflood oil recovery operations in the Wilmington Field within the Los Angeles Basin of California, consisting of the Wilmington Townlot Unit (WTU) and the North Wilmington Unit (NWU). We are also one of the leading developers of coalbed methane natural gas, or CBM, in the Rocky Mountain region. Our CBM operations are focused in the Washakie Basin, which comprises approximately the southeast one-third of the Greater Green River Basin in southwestern Wyoming. Warren also has established a position in the “core-of-the-core” of the Marcellus shale in a highly prolific area of Wyoming County in northeastern Pennsylvania.

The following map illustrates the location of our principal reserves and acreage.
