COLORADO SPRINGS, CO -- (Marketwire) -- 01/04/11 -- ENSERVCO Corporation (OTCBB: ENSV) (previously OTCBB: ASPN), a provider of well-site services to the domestic onshore oil and gas industry, has announced that its stock symbol has changed to "ENSV" from "ASPN" effective at the start of trading today. The new symbol was implemented to better reflect the change in the Company's legal name to ENSERVCO Corporation from Aspen Exploration Corporation.

"Our formal name change and new stock symbol represent the final steps in ENSERVCO's transition to a publicly traded company," said Mike Herman, CEO. "On the operational front, our growth program is proceeding on plan. Our first full winter in the Marcellus Shale is keeping our Heat Waves subsidiary very busy, and we are working to expand capacity in the region to address strong customer demand. We are encouraged by our recent progress and our prospects for growth in fiscal 2011."
