Vietnam Finds Oil in the Basement

From the AAPG Explorer:
Oilfields in the Cuu Long Basin offshore southeastern Vietnam typify the country’s fractured basement reservoirs.
Bach Ho (White Tiger), Vietnam’s largest oilfield, produces almost 280,000 barrels of oil per day from granitoid basement.
Recently, a basement-reservoir play extension in the nearby Su Tu or “lion” fields generated wide industry interest.
The Su Tu Den (Black Lion) field currently produces about 80,000 barrels per day, but PetroVietnam expects to increase output to 200,000 barrels per day within three years.
In September, PetroVietnam announced that up to $300 million dollars will be spent on production enhancement in Cuu Long Block 15-1, where Su Tu Den is located.
