PORT OF SPAIN, Feb. 4 -- EOG Resources Inc. has identified almost 5 tcf of natural gas in leads and prospects from its acreage off eastern Trinidad and Tobago.
In a presentation at the South Trinidad Chamber Energy Conference, EOG Project Manager (Trinidad) Brian Baptiste said the potential reserves were identified following the reprocessing of data, using the latest technologies.
"The reprocessing of the data gave us almost 5 tcf in leads and prospects," Baptiste said. "In the SECC Block we have a drillable prospect of 700 bcf, and in SECC UB and UA Blocks we are looking at 12 prospects totaling over 2 tcf of resources."
The remaining 3 tcf are in its other two blocks.
Baptiste said EOG is confident its seismic data is correct because it can now see "continuity of reflectors" that allow geophysicists to more accurately estimate the reserves.
He pointed to the example of the Pelican Deep prospect in its Pelican field.
Baptiste said that since 1977 it was clear there was gas deeper in Pelican but because the seismic did not allow operators to see the reflectors, they were unable to properly map and estimate the reserves, which would have determined if it were commercial to drill. This, he told the conference, has now changed.
Some of the additional reserves would be found in relatively deep water and deep underground, he said.
"We have already picked the low hanging fruit…the easy gas," Baptiste said. "We have found the big gas in the shallow water and in the shallower sands. Now we have to drill deeper, and we have to find a way to bring this deeper gas in deeper water to shore."
EOG, which operates four blocks off eastern Trinidad, is the third largest producer of natural gas in Trinidad and Tobago.
Its reserves in the Caribbean twin-island nation are 16% of the company's entire reserves.
