CALGARY, ALBERTA–( EMWNews – April 2, 2008) – Canadian Sub-Surface Energy Services Corp. (“CanSub” or the “Company”) (TSX:CSE) is pleased to announce that it has finalized terms of new credit facilities with its banker. Under terms of the new agreement, the Company will convert its existing $44 million revolving, committed facility into two new facilities: a $15 million operating loan and a $30 million committed, term facility. Advances under the new term facility will be repayable over a five-year period.

The new facilities provide lower interest rates and lower stand-by fees and will give CanSub greater borrowing flexibility to pursue strategic opportunities. At December 31, 2007, CanSub had drawn a total of $23.2 million under its previous revolving, committed loan facility. When the new facilities are activated in early April, approximately $22 million in debt will be allocated to the committed, term facility with the remaining debt allocated to the new operating loan.

CanSub is a Calgary-based oilfield services company operating out of field locations throughout the Western Canadian Sedimentary Basin. The Company provides cased-hole wireline, production testing, well optimization and swabbing services to junior, intermediate and senior oil and gas exploration and production companies.
