Benham Rise - the Natural Gas & Solid Methane Treasure Rich Undersea New Philippines Territory
The Philippines will gain 13 million hectares in additional territory, an area slightly smaller than Luzon, should the United Nations approve next year (2012) the government's claim on a region off the coast of Isabela and Aurora, Environment Secretary Ramon Jesus Paje said on Monday (August 15, 2011).
Benham Rise was found off the coast of Aurora province, Northeastern part of Luzon Island and is part of the Philippine continental shelf and its 200 Nautical Mile Exclusive Economic Zone. With just the Pacific Ocean to the east, Hawaii is probably the next closest island.
Benham Rise, also known as Benham Plateau, is a 13-million hectare undersea region east of Luzon. It is enclosed by the coordinates 119°30'E to 132°00'E and 12°10'N to 20°30'N latitude.
The plateau is a massive formation of basalt, a common volcanic rock, and is described in a study as a thickened portion of the Philippine Sea plate's oceanic crust.
Another research notes the similarity of the shape of Benham Rise to the sharp bend of the Luzon coastline, which suggests the sea floor's resistance to subduction (the process by which one plate on the earth's crust is pushed downward beneath another plate because of collision) that may have affected the Philippine fault.
The formation lies within the continental shelf of the Philippines as defined by the 1982 UN Convention on the Law of the Sea (UNCLOS).
Under the UNCLOS, a coastal state's exclusive economic zone extends 370 kilometers (200 nautical miles) from its continental shelf, while its extended continental shelf extends for another 278 km (150 nautical miles).
Paje said the undersea region, called Benham Rise, could turn the Philippines into a natural gas exporter because of the area's huge methane deposits.
Studies conducted by the Department of Environment and Natural Resources (DENR) for the past five years indicate large deposits of methane in solid form, Paje said after a Senate budget hearing.
The government is only awaiting a formal declaration from the UN Convention of the Law of the Sea (UNCLOS) that Benham Rise is on the country's continental shelf and therefore part of its territory, Paje said.
Philippines Legal basis of Expansion
Once the UNCLOS establishes that Benham Rise is part of the Philippines, "we would have legal basis to enter into exploration agreements with private companies to explore… (the area's) resources," said Sen. Franklin Drilon, chair of the chamber's finance committee.
Drilon said a favorable UNCLOSs declaration would mean "increasing the Philippines territory from present 30 million hectares to possibly 43 million hectares" with the inclusion of Benham Rise.
Discussion over Benham Rise generated excitement especially after Paje said that Philippine representatives were just awaiting one more meeting "to answer questions" before a special Unclos committee.
Philippines as a sole claimant
Paje said there was no reason for the UNCLOS committee not to issue a decision favorable to the country "since we are the only claimant, unlike in the western side (where the Spratly Islands are)."
"We have submitted a claim under (UNCLOS) sometime in late 2008. We got a reply from the UN lately (asking us) to answer some questions. They intend to pass a resolution sometime in mid-2012 to approve our claim (that it is) part of the Philippine continental shelf," Paje told reporters after the hearing.
Records showed that the Philippines officially submitted a claim with the UN Commission on the Limits of the Continental Shelf in New York on April 8, 2009.
Davide submission
Hilario Davide, then Philippine ambassador to the United Nations, filed the country's partial submission with the commission.
The United Nations says the continental shelf is "the seabed and subsoil of the submarine areas that extend beyond its territorial sea" up to 370 km (200 nautical miles) from the archipelagic baseline. An extended continental shelf goes farther than 370 km.
The Philippines claims that Benham Rise is an extension of its continental shelf.
Paje said Benham Rise was within the country's 370-km exclusive economic zone.
American geologist
The environment secretary said an American geologist surnamed Benham discovered the area that was between 40 and 2,000 meters below the waterline in 1933.
"But we are able to define categorically that it is attached to our continental shelf only recently. We have proven (to) UNCLOS that it is attached. So now the UN is considering it for decision sometime in 2012," Paje said.
He said gas deposits in the area would enable the country to achieve energy sufficiency.
"Benham Rise is very relevant because of its gas deposits (which has been) confirmed particularly by (the) National Mapping Resource Information Agency. It has given us the data that (the area) contains solid methane. We have not explored it but we have found nodules of methane in the surface and this is very important to us," he said.
Kalayaan, Scarborough Shoal (Panatag Shoal)
The Kalayaan Island Group, which is part of the disputed Spratly Islands and Scarborough Shoal, both located in the West Philippines Sea (South China Sea) and claimed by the Philippines, are also believed to contain oil and natural gas.
Paje said there was the possibility that the country could export gas in the future.
The secretary added that there would be a demand for gas deposits in Benham Rise "because it's much cleaner than (other) fossil fuels."
The DENR formally submitted its proposed ₱16.99-Billion budget for 2012 to the Senate finance committee.
