The Oil Sharing Agreement (CPP) was signed with Sasol on 26 October 2000, with an initial duration of 10-year research. The Area of the CPP geographically overlaps with the Pande Area/Temane APP (Oil Production Agreement), excluding Grudja G6 and G9 formation producing deposits in Pande and Temane gas fields, respectively. About 1800 km of seismic 2D (2001, 2005, 2016) and 125 km2 of seismic 3D (2016) were acquired, and a total of 15 research wells and 22 evaluation holes performed.
The area of the CPP includes several discoveries in sandstone deposits in the formation of the Higher Cretaceous in the Lower Grudja (discovered during the 1960s, 1990s and the granting of the PSA in 2000 until now), such as:
Crow G6A, Tafula G8, Pande G10, G11 and G11A, Pande Este G11 and G11A, Temane G8, Temane Este Profundo (G11, G11A, G12 and G12A) all with natural gas, Inhassoro G6 with light oil halo with gas capping, and Inhassoro G10 with undersaturated light oil.
Based on the findings, two areas of discovery (Pande/Corvo Discovery Area and Temane/Inhassoro Discovery Area) were defined and approved, representing the contours of this CPP contract, after the end of the research period.
In 2015, a Field Development Plan (PdD) for Inhassoro G6, Inhassoro G10, Temane G8, Temane Este Profundo (G11, G11A, G12 and G12A) was presented. The PD was approved in January 2016.
About 117 km of seismic 2D and 125 km2 of 3D seismic were acquired along Inhassoro G6 and G10, and 09 evaluation and development wells were made in the PD deposits from 2016 onwards, resulting in a better understanding of the deposits.
New and small discoveries were made in a well in 2016 during the development phase in the area of the CPP, Temane G6A, G11A and G12, with gas in the shallowest deposits and light oil in the deepest deposits.
In 2019, the following findings were in the Commercial Assessment Period (CAP): Pande G10, G11 and G11A, Pande Eeste G11 and G11A, Corvo G6A and Tafula G8. Two valuation wells were carried out in 2018 to evaluate Pande's deposits.
Total estimates of resources present in PSA discoveries have gas volumes at the site of about 2.5-3 tcf, and recoverable gas volumes of about 1-1.5 tcf. The expected light and condensate recoverable oil is in the range of 30-40 million barrels of liquid. There are still significant uncertainties related to these estimates.
The Oil Production Agreement (APP) was signed on 26 October 2000 by Sasol, National Hydrocarbon Company (ENH), Mozambican Hydrocarbon Company (MCH) and Mozambique Government with the aim of developing and producing gas resources from Pande and Temane Deposits, as part of the "Mozambique for South Africa" Natural Gas Project.
The agreement provides for the construction of:
One Processing Centre (CCF) to initially process 120 MGJ per year;
A gas pipeline extending 865 km to transport the gas produced from Temane (Mozambique) to Secunda (South Africa). This pipeline has five points. offtake to supply gas to the Mozambican market.
The APP covers the deposits of the Pande and Temane gas fields, the formation of the Lower Grudja in the Upper Cretaceous, the Grudja 6 (G6) and Grudja 9 (G9) deposits, respectively. The two deposits have a total gas of about 4.5 tcf as a base estimate.
Natural gas production began in 2004 at Campo Temane, and in 2009 the Campo de Pande was coupled to the CPF. The total amount of gas produced from 2004 to 2018 is 2,087 MGJ (million Giga Joules), equivalent to about 1,8 tcf or 50,250 million Nm3 – normal cubic meters gas, and the condensate produced is 7.1 MMbbl (million barrels).
In each of the two gas fields about 30 holes were made in previous contracts and in the APP, including evaluation as well as development wells. The two fields are covered by 2D seismic data from different crops (six acquisitions of 2D seismic from 1990 to 2005, in addition to older seismics).
In 2016, Sasol acquired 42 km2 3D seismic in the central part of the Pande field around the well Pande-4, and in 2018 performed the first horizontal filling well in the G6 deposit in the Pande Field.
The CCPP was signed in October 2018 with Sasol and ENH as a result of the 5th area concession competition. The area is located in the part onshore of the Mozambique Basin, near the gas deposits of Pande and Temane, in the northern province of Inhambane. The research period has a duration of 8 years and was subdivided into 3 research sub-periods of 4 + 2 + 2 years.

The CCPP was signed in the light of Decree 38/2008 of 17 October and approved by the Council of Ministers and concluded on 31 October 2008 between the Government and National Hydrocarbon Company (From now on called "ENH") which then held 100% shares, with effect from April 2009. Subsequently ENH gave its participatory interest to Buzi Hydrocarbons Pte. Lda. (BHPL), as a strategic partner becoming this, the dealership and operator of this Block, with 75% of participatory interest and the partner ENH with 25%.
Minimum work obligations:
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.
