Concession Areas

Explore our main areas

The Rovuma Basin, located on the east coast of Africa, emerged as a strategic area for researching offshore energy resources. Its deep, resource-rich waters have attracted the attention of energy companies around the world. Down are listed the areas of grant of research and productioned in the Rovuma Sedimentary Basin, where the activity of research and productioned hydrocarbon is in progress or planned.

The A5-A concession area is the result of the public tender launched in October 2014 for the granting of areas for the Research and Production of Hydrocarbons in Mozambique. Eni Mozambico S.p.A., Sasol Petroleum Exploration Lda. and National Hydrocarbon Company, E.P. (ENH, EP), they were awarded the Offshore Angoche A5-A area whose extension is 4.612 km2, located in the maritime part of the Republic of Mozambique. The Oil Research and Production Grant Agreement (CCPP) was signed in October 2018, having as effective date 1 January 2019; The area is operated by ENI Mozambico S.p. A with 49.5% participations and partners to Qatar Energy (25%), Sasol Petroleum (10%) and ENH, E.P. (15%).

AREA 1

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.

PROSPERITY DISCOVERING AREA

Median estimate of 43 tcf (cubic foot trillions) of gas.

4 Transzonal Reservoirs:

  • Upper North Oligocene;
  • Upper South Oligocene;
  • Oligocene Lower;
  • Upper Eocene;

TUBARAN DISCOVER AREA

Median estimate of 3.4 (cubic foot trillions) Tcf of natural gas.

THE AREA OF DISCOVERMENT

Median estimate of 8.4 Tcf (cubulated foot trillions) of natural gas

The Paleocene Reservoirs.

THE AREA OF DISCOVERMENT

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.

UNKNOWN TUGRE AND ORCA (CRETACICO LEQUE 1, 2 E 3), ROVUMA OFFSHORE AREA 1

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.

FOUND OUT ORCA (LECK OF MEDIO PALEOCEN), ROVUMA OFFSHORE AREA 1

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.

UNCOVERED TUBARON (EOCENO), ROVUMA OFFSHORE AREA 1

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.
