  Note on decommissioning and abandonment of wells

  ANP is making available to the public and interested companies information regarding legal proceedings that have mandated the abandonment of wells and the reclamation of areas associated with blocks in the São Francisco and Recôncavo basins; which are available in version 04.03 of the current tender protocol for the Open Acreage of Concession (OPC). This note aims to clarify the responsibilities related to well abandonment and reclamation of areas previously granted to the companies Cisco Oil and Gas S.A. and Petra Energia S.A. in the São Francisco Basin, and to Tek Óleo e Gás Ltda. in the Recôncavo Basin, ensuring that potential auction participants are fully informed.

  These blocks are currently included in the list of areas being offered, but due to the history of exploration activities carried out in the past by operators who did not continue their concession contracts, regulatory obligations regarding well decommissioning and abandonment remain outstanding. ANP emphasizes that these obligations will be fulfilled in parallel with new exploration activities to be carried out by the companies that win these blocks in future OPC cycles.

  Note regarding the Court Ruling

  Pursuant to a court ruling issued in the case file of Public Civil Action No. 0030652-38.2014.4.01.3300, ANP hereby makes public the decision issued by the 13th FEDERAL CIVIL CHAMBER OF SJBA, which declared null and void the effects arising from the 12th Bidding Round conducted by the National Agency of Petroleum, Natural Gas, and Biofuels —ANP—and the contracts resulting therefrom regarding the availability of blocks in the Recôncavo Basin for shale gas exploration through hydraulic fracturing (Sectors SREGT2 and SREGT4), due to the absence of prior regulation by CONAMA.

  The ruling further orders ANP to refrain from conducting bidding procedures and from granting concessions for areas in the Recôncavo Basin without prior regulations from CONAMA and an Environmental Assessment of Sedimentary Areas (AAAS), specifically regarding the use of hydraulic fracturing for shale extraction.
