Cotton Valley Haynesville-Bossier Trend – The East Texas Basin has periodically excited the oil and gas industry since 1930 with the discovery of the giant East Texas Field. As the industry progressively drilled deeper throughout the basin tremendous new conventional oil and gas reserves have been developed. Now, since the onset of the Barnett Shale play, the industry has been looking for new unconventional gas reservoirs in black, petroliferous shale sequences present in many basins. This search activity has developed an exceptional new play with vertical and now horizontal drilling in the Cotton Valley Haynesville-Bossier sequent on both the eastern and western sides of the East Texas Basin. Produced gas reserves from conventional, vertical wells completed in the Haynesville-Bossier are in the trillions of cubic feet of gas. The potential unconventional, horizontal well gas reserves are estimated to be several times larger. PPI has acquired leasehold interests in Cotton Valley Haynesville-Bossier producing areas on the west flank of the East Texas Basin where it presently holds interests in several large gas units in which vertical wells have been completed and horizontal Bossier wells are planned. The company also holds leasehold interests in North Louisiana areas on trend with recent Haynesville-Bossier drilling and completions on the east flank of the East Texas Basin and contiguous portions of Northwestern Louisiana.
