MANILA: Philippine President Ferdinand Marcos Jr. announced the discovery of a new natural gas deposit near an existing gas field in waters facing the disputed South China Sea, which could shield his country from a potential power crisis.

The discovery of the gas reservoir northwest off Palawan province was “significant” and could eventually supply power to more than 5.7 million households annually, Marcos said Monday.

The undersea reservoir is estimated to contain about 98 billion cubic feet (2.7 billion cubic meters) of gas. Initial tests showed 60 million cubic feet (1.6 million cubic meters) of gas could be extracted each day from the well, Marcos said without providing other details including when commercial production could start.

“This helps Malampaya’s contribution and strengthens our domestic gas supply for many years to come,” Marcos said. “Aside from the natural gas, the discovery also includes condensate, which is a high-value liquid fuel.”

The new gas deposit, called Malampaya East 1, was discovered by a Philippine consortium about 5 kilometers (3.1 miles) east of the main Malampaya gas field, where commercial gas production started more than two decades ago and was projected to considerably decline in a few years.
