Heartland Oil and Gas Corp. (OTCBB: HTOG) (FWB: HOCA) has achieved another milestone as it continues to expand the production from its oil and gas properties, posting revenues in excess of $220,000 from its natural gas fields in Texas. Combined with its expanding coalbed methane production in Kansas, Heartland posted total natural gas sales of more than $330,000 in May.

With the completion of its nearly 4 mile pipeline expansion project and the subsequent connection of 12 additional wells in Kansas, Heartland expects to double its coalbed methane production. This accomplishment will also allow Heartland to accelerate its efforts to further expand its natural gas production in Texas in the next phase of its well improvement plans directed at the 5 Barnett Shale wells Heartland has completed in Palo Pinto County. As previously reported, those improvements will include the installation of a salt water disposal well and connection to a low pressure natural gas sales line.

"With natural gas prices projected to continue their escalation, these additional production increases should result in exponential revenue growth," remarked Heartland Spokesman Jack Baker. "In light of the many obstacles we have encountered as we have pursued our business plan, including the tightening credit markets, soaring oil field service and supply prices and inclement weather, the undeniable success we are now achieving is most satisfying. These successes should translate into expanding shareholder value, the ultimate goal of every public company."
