Block A is located north of and contiguous with SC 72 in offshore NW Palawan and some 180 to 375 km from Palawan Island. It covers all of Nares Bank and parts of the greater Recto Bank, with an area of 14,300 sq. km. The water depth across the block broadly ranges from 20 m to 2,500 m. Apart from a few academic studies using mostly potential fields of geophysical data and the legacy Joint Marine Seismic Undertaking (JMSU) 2D dataset, which is unavailable to PXP, there are no recent subsurface data in Block A. The closest relevant subsurface information in Block A comes from SC 72, with Reed Bank A-1 and B-1 wells located in the northern part of SC 72.
On September 14, 2020, the DOE opened the bid submitted by PXP in March 2020 and found the application documents complete and thus qualified to undergo further substantive (legal, technical, and financial) evaluation. The application remains under process with the DOE.
Once a Service Contract is granted, the proposed work program for the first sub-phase will include the acquisition of at least 2,200 line-km of 2D seismic data, as well as marine gravity and magnetic data.
The Cadlao Block (formerly SC 6B) covers an area of 1,030 sq. km and contains the Cadlao Oil Field.
In late 2021, Nido Petroleum, a member of the SC 6B Consortium, submitted a farm-in proposal to increase its participating interest from 9.09% to 72.727% and assume operatorship of the block. Under the proposal, Nido would fund 100% of the drilling, extended well test (EWT), and subsequent development of the Cadlao Field in exchange for the additional interest. A farm-in agreement (FIA) was executed on February 11, 2022.
Nido proposed a two-phase redevelopment of the Cadlao Field:
From November 28 to December 1, 2022, Nido conducted a geophysical site survey at Cadlao using the vessel, Cassandra VI. The survey aimed to identify possible constraints and hazards on the seafloor at the Cadlao-4 well location.
On December 19, 2022, after Nido and the JV completed the required actions and submitted the necessary documents, the DOE approved the transfer of operatorship of SC 6B to Nido.
On January 5, 2024, the SC 6B Consortium submitted a letter of intent to the DOE to apply for a Development and Production Petroleum SC (DP PSC) before the end of the SC 6B production term. The new SC will replace SC 6B, which expires on February 28, 2024.
On January 26, 2024, Nido submitted the application documents for the SC 6B block and additional open areas, including a copy of the Plan of Development (POD) for the Cadlao Field. The Consortium is now awaiting the award of the DP PSC.
