A significant gas discovery has been made on Trinidad & Tobago’s deepwater Block 22 by Calgary-based senior producer Petro-Canada Corp. The Cassra-1 well was drilled in 430 meters of water to a depth of 1,712 meters. The reservoir flowed 23 million cu. ft. a day on a drillstem test. The prospect targeted a 68-sq.- kilometer seismic anomaly and contingent resources could be between 600 billion and 1.3 trillion cu. ft., the company reports. Petro-Canada operates the well and holds a 90% interest. An appraisal well, Cassra-2, will be drilled next.
