The new acreage, designated as the South Oklahoma Project, covers highly prospective Mississippi Limestone targets.
These targets, through sub-surface geological mapping and extensive engineering, show Mississippi targets similar and analogous to the recently discovered oil and gas reservoir being exploited at the North Oklahoma Project.
The company said additional lands may be acquired and added to the 3,000 acres as leasing is ongoing.
American Petro-Hunter has identified five key areas under the 3,000 acres which, if developed on 160 acre spacing, could allow future development of 18 additional locations for horizontal wells.
Targets will be refined and prioritized over the next several months, with plans to spud the first well in late 2011 or early 2012, the company said.
