BP Trinidad & Tobago (BPTT) on Monday said it has discovered an estimated 1 trillion cubic feet (tcf) of gas offshore of Trinidad, doubling the estimated gas in the previously discovered Savonette gas field to 2tcf.
"To run a 1m tonne/year methanol plant you need 0.8tcf of gas for 20 years," a source close to the methanol industry said.
"They found 1tcf so I would say that is significant," the source said.
BPTT made the announcement of the discovery during a meeting in London on Monday between Trinidad and BP officials.
The Savonette 4 appraisal well was drilled into an untested fault block east of the original Savonette field discovery well, in water depths of almost 300 feet in the Columbus basin, approximately 80km off the southeast coast of Trinidad.
The well was drilled to a total depth of 18,678 feet and penetrated hydrocarbon-bearing reservoirs in two intervals with discovered gas in place exceeding initial estimates, BPTT said.
The Savonette field was discovered in 2004 by the Chachalaca exploration well and began production in 2009 through a normally unmanned platform.
Based on the success of the Savonette 4 well, BPTT is proposing to drill a further two development wells into the Savonette reservoirs.
The gas discovered began production in October 2012, with the Savonette 4 well currently flowing at approximately 225 million standard cubic feet/day (mmscf/d), ramping up to 250mmscf/d.
If successful, the two additional development wells are also expected to be brought into production over the next year to 18 months, BPTT said.
“This is exciting news for both BPTT and the industry since this represents the largest discovery for BPTT since 2005,” said BPTT president Norman Christie.
Trinidad hosts 11 ammonia plants and seven methanol plants.
