About INP

The National Petroleum Institute, abbreviated as INP, established by Decree No 25/2004 of 20 August, is, under the terms of Law No 8/2026 of 3 June, Authority Regulator Oil in Mozambique.

It is active in the management, supervision and regulation of the oil industry.

In the exercise of its powers and powers, the INP shall have decision-making and sanctioning powers under the law. As the Oil Regulatory Authority, the INP is responsible, within the framework of its legal tasks, for the definition of guidelines for the participation of the public and private sectors, as well as for the licensing, regulation, supervision, supervision and control of oil operations activities.

It is supervised by the Minister who oversees the oil area (MIREME).

Mission

Administration of oil resources for social benefit, ensuring compliance with existing legislation and the sustainable development of the sector.

View

The exploration of hydrocarbons in Mozambique, which began in the 1900s, resulted in the historical discoveries of natural gas in Pande, Búzi and Temane in the 1960s, with the production to be started in 2004 in the Mozambique Basin, whose reserves total 6 trillion cubic feet (Tscf).

Research Phases

Phase 01 · Geology

Geological Knowledge

Six sedimentary basins mapped in Mozambique, the Rovuma Basin holds the greatest potential (~180 Tscf). The research began in 1904; commercial production started in 2004 in Pande–Temane.

Phase 02 · Potential

Assessment of the Oil Potential

Four layers of geological, geophysical, geochemical and drilling data reduce uncertainty about whether a basin contains hydrocarbons. The oil system only exists when mother rock, reservoir, seal, cheat and migration coincide in geological time.

Phase 06 · GDE

Regional Deposition Environment

The modelling of the Regional Deposition Environment (GDE) provides for the distribution of reservoir rocks, seal and mother in the basins of Rovuma and Mozambique reducing geological risk and guiding the location of wells.

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.

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.
