Business Editors 
VANCOUVER, British Columbia--(BUSINESS WIRE)--Feb. 16, 2000--
David Patterson Chairman of the EKHO Project consortium is
pleased to announce that the EKHO No. 1 test well, spudded February 7,
2000, has drilled past 11,000 feet. The total target depth for the
well is 19,500 feet. 
Located 40 miles northwest of Bakersfield, California, the EKHO
No. 1 is the first of three wells scheduled to test a large
structurally controlled stratigraphic trap identified geologically and
confirmed by seismic data. The primary target formation is in the
Temblor sandstones, a thick package of Middle and Lower Miocene
horizons in which previous drilling identified hydrocarbon prone
sections. Technological advances within the industry over the past 25
years provide the opportunity to exploit these zones. In addition to
the Temblor Sandstones, secondary targets exist above the target
