Grant A5-B comprises an area of 6080 Km2 and is located in the maritime part, north of the Sedimentary Basin of Mozambique, at depths of water ranging from 1800-2500 meters.
This area results from the 5th Hydrocarbon Research and Production Areas Award Competition launched in 2014, and was awarded and awarded a Grant for Research and Production Agreement (CCPP) to the Consortium constituted by the companies Exxon Mobil Exploration and Production Mozambique, Rosneft LTD, and ENH.E.P (National Company Hydrocarbon Enterprise).
The CCPP between the Consortium and Government of the Republic of Mozambique was signed on 14 November 2018 and made effective on 1 December 2018, with the research period containing a duration of eight (8) years divided into 3 Subperiods, namely (4+2+2) years.
The A5-B grant area was operated by ExxonMobil Exploration and Production Mozambique (Angoche A5-B) B.V. with 40 % participatory interest and Rosneft LTD, ENI Mozambico Sp. A , National Hydrocarbon Company E.P., Qatar Energy (QP ) with 20%, 10%, 20% and 10% respectively as partners.

The validation of the potential of the area culminated in the identification of several plays/leads (geological bodies), which need to be evaluated to certify the prospectivity and testing of the presence of hydrocarbons from the performance of research wells.
Following the public tender launched in October 2014, for the granting of areas for the research and production of hydrocarbons to ExxonMobil Mozambique Exploration and Production, Limited, RN Zambeze South PTE. LTD and National Hydrocarbon Company, E.P (ENH, EP), were awarded the offshore area of the Zambeze Delta designated Z5-C, located in the maritime part of the Republic of Mozambique. The Oil Research and Production Grant Agreement (CCPP) was signed in October 2018.
The area is available following the termination of concession rights to the consortium mentioned above.
Following the public tender launched in October 2014, for the granting of areas for the research and production of hydrocarbons to ExxonMobil Mozambique Exploration and Production, Limited, RN Zambeze North PTE. LTD and the National Hydrocarbon Company, E.P (ENH, EP), were awarded the offshore area of the Zambezi Delta designated Z5-D, located in the maritime part of the Republic of Mozambique. The Oil Research and Production Grant Agreement (CCPP) was signed in October 2018.
The area is available following the termination of the concession rights to the consortium mentioned above.
As a result of the direct negotiations, the government of Mozambique signed the CCPP with Sasol and ENH in June 2005. The block is located in the sedimentary basin of Mozambique, in the marine environment comprising shallow waters and north of Inhambane province.
In the area, as a result of research operations carried out by the aforementioned consortium, it culminated with discoveries of gas deposits. The operator ceased the concession rights and the discovery is currently adjacent to the areas awarded when the sixth concession contest for the oil research block in the Save region in northern Inhambane.
Following the 2nd open competition for the granting of areas for the research and production of hydrocarbons, the companies Anadarko Mozambique Area 1 and the National Hydrocarbon Company were awarded Area 1 in offshore environment of the Rovuma Basin. The area is located in the northern part of Cabo Delgado Province, in shallow to very deep waters. The Hydrocarbon Research and Production Areas Grant Agreement (CCPP) was signed on 20 December 2006 and is effective as of 1 February 2007.
Median estimate of 43 tcf (cubic foot trillions) of gas.
4 Transzonal Reservoirs:
Median estimate of 3.4 (cubic foot trillions) Tcf of natural gas.
Median estimate of 8.4 Tcf (cubulated foot trillions) of natural gas
The Paleocene Reservoirs.
Tigris Shark Discovery Area (1254 km2), has 3 reservoirs of the Cretaceous (K1,K2 and K3), the K2 being the best in Orca and Shark-Tigre and has a median estimate of 0.323 Tcf (cubic foot trillions) of natural gas.
The complete technical evaluation of the potential of the Cretaceous in Area 1, between the Areas of Discovery Tubarão Tigre and Orca, determined that it contains small, discontinuous and low quality reservoirs, and this would probably present significant challenges in the supply of trade amounts of gas. Of the three reservoirs of Cretaceous (K1,K2 and K3) evaluated, the best is K2 in Orca and Shark-Tiger that has an average resource of 0.323 Tcf (cubic foot trillions) of natural gas.
This discovery was made in Area 1 by Anadarko in 2013 through borehole Orca-1, whose reservoir is the age of the Middle Paleocene, was subsequently evaluated by the holes Manta-1, Orca-2, Orca-3 and Orca-4.
The discovery is located about 10 km from the coast line, 250 km from the city of Pemba. This reservoir is of Middle Paleocene age and is not shared. The average estimate of resources is about 8.4 Tcf (cubulated foot trillions) of natural gas in situ, according to estimates submitted by Total.
The reservoir in the Orca discovery lies at depths ranging from 4000 to 5000m below the mid sea level, and the water column from about 600m to 1200m. The extension is about 30 km.
This discovery was made by Anadarko in January 2011 through the Jaw-1 hole and evaluated by the Shark-2 hole (negative) in 2013. The discovery is located about 25 km from the coast line, 50 Km of the Northeast of the district of Mocímboa da Praia and 200 Km of the Northeast of Pemba City.
The reservoir is completely in Area 1. The average estimate of resources is about 3.4 tcf (cubic foot trillions) of gas in situ.
The reservoir is at a depth of 3500 to 4000 metres below the average sea level. The water column ranges from 800 to 1200 meters. The extent of the Shark discovery is about 20 km east-oriented.
