BusinessWorld May 19, 2021 | 8:35 pm THE remaining reserves in the Malampaya gas field will be completely depleted by the first quarter of 2027, a senator said Tuesday, citing estimates from the Department of Energy (DoE). “The Malampaya service contract is set to expire in 2024. Even if the service contract is extended, the DoE projects that the estimated 858,834 million standard cubic feet remaining in the Malampaya field as of Sept. 30, 2020 would be completely exhausted by the first quarter of 2027,” Sen. Sherwin T. Gatchalian said in a speech sponsoring a bill regulating the development of the midstream natural gas industry on Tuesday. Mr. Gatchalian chairs the senate committee on energy.
