The rights and obligations conferred by concessions which are obligatory under this article are to be regarded as following from the initial concessions which, under the provisions of this Act, include the right to receive such subsequent concessions.

ARTICLE 12.Designation of petroleum regions. — For purposes of this Act, the Secretary of Agriculture and Natural Resources, after due study of the different prospective petroleum lands of the Philippines, may divide them into a number of prospective petroleum regions, delimiting their extent and boundaries, and issuing the order and notice establishing such regions.

In the event such contract is executed, the same shall be submitted to the Congress of the Philippines for its approval.

No petroleum reservation may be established over any areas covered by application for Exploration or Exploitation Concession already filed or granted. If at any time after the establishment of a petroleum reservation, the Secretary of Agriculture and Natural Resources, after due investigation, should find it to the best interest of the Government, that any area within the reservation should be opened to Exploration or Exploitation Concession under the provisions of this Act, such area or areas may be recommended to be released from the reservation and declared open to Exploration or Exploitation Concession under this Act by an executive proclamation of the President concurred in by a joint resolution of the Congress of the Philippines.

ARTICLE 14.Free areas. — All lands within the territorial limits of the Philippines including those submerged beneath seas, bays, lakes, rivers, lagoons, or the territorial waters, or on the continental shelf, or its analogue in an archipelago, but which are not within the National Reserve Areas, or Petroleum Reservations, or covered by valid and existing Exploration or Exploitation Concession, or Petroleum Drilling Leases acquired under the Petroleum Act (Act No. 2932), or of petroleum mining claims located and held under the Act of Congress of July first, nineteen hundred and two, as amended, are called Free Areas and as such are open to application for Exploration Concession by any duly qualified person.

Application for such areas shall be filed with the Director of Mines in accordance with article twenty-eight of this Act, and the concession may be granted by the Secretary of Agriculture and Natural Resources in favor of the applicant whose offer shall be found best to serve the interest of the Government.

ARTICLE 16.Lands covered by concessions are subject to public easements. — All lands covered by concessions granted under this Act shall be subject to public easement established or recognized by existing or future laws: Provided, That the rights of the petroleum concessionaire to search, prospect, and drill for, produce, extract, transport, store, process, and treat petroleum on, under, and from said lands, and other rights granted to him under this Act are recognized: And provided, further, That in case public easement shall be established after the effective date of the concession contract the concessionaire shall be paid just compensation for actual damages that he may suffer as a consequence thereof.

The map shall be submitted together with the technical description of the corner markings and the metes and bounds or distances and bearings of the sides of the block. The technical description and map shall also indicate the bearings and distances of the tie line from some known reference location monument to one corner, preferably Number 1, of the block, in such a way that the block desired can be plotted from such tie line and descriptions on the Progress or Index Map of the Bureau of Mines, where all areas applied for shall be plotted to show the relative positions of such areas.

The boundaries of the block desired shall be well-established on the ground by placing permanent and conspicuous monuments, posts or mounds of earth on the corners, so that at any time, the block can be identified, and later be tied to accurate surveys. The bearings and distances of the block applied for exploration shall be sufficiently accurate so that the approximate area of the block can be computed from the given bearings and distances on the sides.

The Secretary of Agriculture and Natural Resources, upon recommendation of the Director of Mines, may give holders of petroleum exploration concession where the provisions of the Petroleum Act, the regulation and the terms and conditions of the concession contract have been complied with for two or more concession years and where the progress of exploration is such that exploration drilling is the next logical step in the operation in accordance with good petroleum field practice, as indicated by technical reports duly submitted to the Director of Mines showing that adequate geological field work was performed and delineating at least a favorable structure with favorable lighology and with satisfactory paleontological correlations of surface and possibly subsurface rock units, and/or when exploratory drilling is shown to be necessary by satisfactory geophysical survey, a moratorium on work obligations for a period of two concession years from the date of the approval of this Act. The term "exploratory drilling" shall mean the drilling of wells suitable to the production of petroleum and does not include drilling wells suitable only for stratigraphic information.

Any amount spent in excess of the minimum required in any concession year for any of the said concessions herein referred to, may, at the election of the concessionaire, be credited against exploration work obligations in the same year for other concessions in the same sedimentary basin, or carried forward and credited against future exploration work obligations on any of the concession herein referred to: Provided, That, in the event such excess expenditure is carried forward to the succeeding year or years and credited against the work obligations for other concessions the concessionaire shall be obligated to continue exploration operations in each of the said other concessions to the extent of twenty-five per centum of the minimum amount of work obligations required in any concession year. Failure to comply with this obligation shall be considered as non-compliance with the provisions of this Act.
