Philippines finds undersea gas near Palawan - Malampaya East‑1 holds 98 bcf

Philippine officials announce a new undersea natural gas discovery northwest of Palawan, a find the government says could bolster a struggling domestic gas sector and ease reliance on imports. The well, named Malampaya East-1 or MAE-1, is located roughly 5 kilometers east of the existing Malampaya gas-to-power project and sits within Service Contract 38. The field is estimated to contain about 98 billion cubic feet (bcf) of gas in place, roughly 2.7 to 2.8 billion cubic metres (bcm).

Initial flow testing produced about 60 million cubic feet per day (mmcfd), equivalent to roughly 1.7 million cubic metres per day. President Ferdinand Marcos Jr. described the test as indicating further upside and called the discovery "a high-productivity resource comparable to the original Malampaya wells." The find also includes condensate, a light hydrocarbon liquid that enhances commercial value and could support power-supply stabilization if developed.

On an energy-equivalence basis, the 98 bcf estimate has been framed as roughly 14 billion kilowatt-hours of electricity per year, a quantity variously described as enough to supply several million households for a year. That scale, while modest by regional standards, would represent a meaningful domestic addition after years of dwindling local output and growing imports. The Philippines began importing gas in 2023 as production from the aging Malampaya field declined.

MAE-1 lies in waters facing the South China Sea and is operated under the SC 38 consortium led by Prime Energy in partnership with UC38, PNOC Exploration Corporation, and Prime Oil and Gas Inc. Reports indicate a Philippine group led by businessman Enrique Razon began drilling in the block last year. The government and operators will now need to undertake appraisal drilling, reserve certification and field-development planning to convert the in-place estimate into recoverable reserves and production.

Markets reacted swiftly to the announcement, with shares of domestic energy companies rising intraday after the news. PXP Energy Corp. gained as much as 20.8 percent, Oriental Petroleum rose up to 8.3 percent, and First Gen Corp. moved as much as 10.2 percent in trading. Analysts cautioned that infrastructure, financing and regulatory approvals will determine the timing and scale of commercial benefits, and that any material relief to national supply is likely to take years rather than months.

Context sharpens both the promise and the limitations of MAE-1. The discovery is the country’s first significant gas find in over a decade and could extend the productive life of the Malampaya area, which for decades has been a cornerstone of the power system. Depending on the metric, Malampaya has been credited with supplying around a fifth of the nation’s energy needs or roughly 40 percent of power to Luzon at various times. Meanwhile the Philippines remains one of Southeast Asia’s most coal-dependent major grids, though a recent shift toward more liquefied natural gas helped produce the first decline in coal-fired generation in 17 years.

Despite the immediate optimism, MAE-1 is small compared with giant regional fields measured in the trillions of cubic feet. The critical next steps will be technical appraisal, project financing and new downstream infrastructure. If those pieces fall into place, the discovery could reduce import dependence and support a longer-term transition to lower-emission gas-fired generation; if they do not, the find will remain an important but incremental addition to the country’s hydrocarbon inventory.
