US oil giant Exxon Mobil Corp discovered hydrocarbons in August off the coast of Da Nang, in central Vietnam, the company said on Thursday.
The Financial Times had reported that ExxonMobil has made a potentially significant gas discovery off the coast of central Vietnam.
"We can confirm ExxonMobil Exploration and Production Vietnam Limited drilled its second exploration well offshore Da Nang in August 2011 and encountered hydrocarbons," the world's largest oil group by market capitalization said.
"Data from the well are being analyzed. Our first well offshore Vietnam did not encounter hydrocarbons," Patrick McGinn, from ExxonMobil's Upstream Media Relations, said in the statement.
The FT said the second well is in block 118 off the coast of Da Nang. The company did not comment on the size of the discovery.
The newspaper cited an executive from state-run PetroVietnam, ExxonMobil's production partner, as saying they had found gas, while an executive from another oil firm prospecting nearby said it was "a potentially significant find", given the geology of the area.
ExxonMobil has a license from the Vietnamese government to explore blocks 117, 118 and 119 off the coast of Da Nang. This area falls well within what Vietnam claims is its 200-mile exclusive economic zone under international maritime law, the FT said.
