Feb 2024: Eni started production at its Congo LNG project following introduction of 1st gas into Tango FLNG. The project is expected to reach total capacity of 4.5 bcm of gas per year from 2025 exploiting gas resources of the Marine XII area including a 2nd FLNG plant operative in 2025.The cargo will sail to Piombino's regasification terminal in Italy.


Dec 2023: Eni introduced first gas into the Tango FLNG facility. It is scheduled to produce its first LNG cargo by Q1 2024 with a capacity of 0.6 mmtpa. The Congo LNG project will see the installation of two FLNG plants to reach total LNG production capacity of 3 mmtpa per year from the Marine XII project.

Jun 2023: Perenco Congo and its partners, SNPC, AOGC and PetroCongo, brought onstream the Boatou offshore concession. Elf discovered the field in 1984, 55 kms from Pointe-Noire. Four wells produce via a platform at a combined rate of 4,500 bbls per day into infrastructure at Likouala.

Apr 2023: Eni (operator, 65%), PJSC Lukoil (25%) and SNPC (10%) began their 3 mmtpa LNG development. Gas is supplied by the Marine XII concession and will use 2 FLNG plants at the Nenè and Litchendjili fields. The first plant is the 0.6 mmtpa Tango FLNG. The second plant will operate from 2025 with a capacity of 2.4 mmtpa, 29 new wells and 8 platforms.


Dec 2022: Eni has launched its 2nd floating FLNG project in the Marine XII block which will be anchored at a water depth of 40m. Its 1st is Tango FLNG with production beginning in 2023. The 2nd project will bring production capacity to 4.5 bcm per year in 2025.

Aug 2022: Eni acquired Export LNG which owns the Tango FLNG liquefaction facility. It will be used as part of the gas development project in the Marine XII Block. Tango FLNG has a capacity of around 1 bcm per year input. LNG production from Marine XII is expected to begin in 2023.

Apr 2022: Eni will increase gas production and supply primarily through the development of an LNG project to start in 2023. The project will have a capacity of over 3mmtpa when fully operational. Eni currently supplies gas to the Congo Power Plant.


Dec 2021: PetroNor reports that reserves have been upgraded for the Tchibeli NE development within the PNGF Sud Block, which was discovered in 1989. The license is operated by Perenco. Development will involve dry wellheads on a new jack-up platform with a tieback to the Litanzi platform for processing.


Jan 2020: The country has started promoting all open blocks. On offer are 5 in the interior Cuvette basin and 10 in the Coastal basin, 7 of which are offshore. In 2019 PGS reprocessed seismic data over the offshore Coastal basin to deliver a dataset called Congo MegaSurveyPlus. They now plan to acquire a new regional 3D survey over the shallow-water shelf.


Jan 2019: Anglo African Oil & Gas announced that the TLP-103C well at its Tilapia licence has intersected the targeted Djeno reservoir horizon and that oil was encountered. The Tilapia field is 1.8 kms offshore in the Lower Congo Basin but is drilled from an onshore location. A further well, TLP-104 is now planned as well as the upgrading of topside facilities.


Nov 2018: An oil exploration bidding round has been launched offering 18 blocks. Phase II of the 2018/19 licensing round has 5 blocks available in the onshore Cuvette Basin, 5 in the shallow offshore, 5 in deep waters, and 3 onshore in the coastal basin.

June 2018: Congo-Brazzaville has joined OPEC. Membership was approved during OPEC's 174th meeting in Vienna. The government said in January that it wanted to join OPEC as it moves ahead with new projects with a target of 350,000 barrels per day in 2018.


Mar 2017: Total (operator, 53.5%) started production from the Moho Nord deep offshore project. It has a production capacity of 100,000 bbls of oil equivalent per day through 34 wells tied back to a TLP and to Likouf, a new FPU. The oil is processed on Likouf and exported by pipeline to the Djeno onshore terminal. Partners are Chevron (31.5%) and SNPC (15%).


Nov 2016: A new shallow water licensing round for 2017/2018 will be carried out after the 2016 round, for 8 deep and ultra-deep blocks and five onshore blocks in the Coastal and Cuvette basins, closes at the end of March 2017. The new licensing round will include both pre-salt and post-salt plays.


Dec 2015: Total (operator, 53.5%) brought onstream Moho Phase 1b (capacity 40,000 bbls per day) in water depths up to 1,200 m. It includes 11 new subsea wells and 2  subsea multiphase pumps tied back to the Moho Bilondo FPU. The Moho Nord development will add a further 100,000 bbls per day capacity. Partners are Chevron (31.5%) and SNPC (15%).

Nov 2015: Eni has discovered significant gas and condensate reserves in the Nkala Marine-1 well, in the Marine XII block. It intends to appraise the discovery. Eni is operator with 65%, pertnered with New Age (25%) and SNPC (25%).

Nov 2015: Chevron (operator, 15.75%) commenced production from the Lianzi field in a unitized zone shared with Angola in 900m of water. Oil is tied into the Benguela Belize–Lobito Tomboco platform in Angola’s Block 14. Partners are Cabinda Gulf Oil (15.5%), Total (26.75%), Angola Block 14 (10 %), Eni (10%), Sonangol (10%), SNPC (7.5%) and GALP (4.5%).

Development will take place in stages and will include over 30 wells with a plateau of over 140,000 bbls of oil per day. Eni is operator (65%) with New Age (25%) and SNPC (10%).


Oct 2014: Eni has made a light oil discovery in the Minsala Marine well in 75m of water within the Marine XII Block, 12 kms from the  Nene Marine discovery. This is the third discovery in the Marine XII permit pre-salt play following the Litchjendily and Nene Marine wells, which are both already under development. Eni is operator of the block with 65%.

Apr 2014: The state oil company Societe Nationale des Petroles du Congo (SNPC) hopes to pump more oil from onshore fields. It has completed 2 geological surveys in the Mengo-Kundji-Bindi (MKB) permit and is using hydraulic fracturing on the Kundji field and will use the same technique on the Mengo field. SNPC’s partners are Petroci and Orion Oil and Gas.

Mar 2014: The testing of the CNOOC-operated E-1 exploration well (Elephant) in 550m of water in the Haute Mer A licence confirmed the discovery of gas and heavy oil. The well was  targeting a turbiditic Tertiary play similar to fields adjacent to the  area, such as the Total-operated Moho Bilondo and the Chevron-operated Block 14 in Angola.

Feb 2014: Eni has discovered oil and wet gas in the Nene Marine 3 well in the Marine XII Block in a water depth of 28m. Nene Marine 3 is 2 kms from the discovery well Nene Marine 1. Eni estimates the field to contain 1.2 bn bbls of oil and 30 bcm of gas in place. Eni holds 65% along with New Age (25%) and the national oil company, SNPC (10%)


Nov 2013: Congo will award 10 onshore and offshore blocks by early 2014 in a new licensing round, including in the onshore Cuvette Basin where 3 blocks have already been awarded and 7 remain open and shallow water blocks abandoned by major oil companies. Meanwhile Eni is exploring the Ngolo block in the Cuvette Basin and developing the Litchendjili offshore gas field.

Nov 2013: Production from the deep water Azurite field in the Mer Profonde Sud (MPS) block ceased  on 1 November 2013 after poor performance from the field since 2009.  Murphy is operator with 50% along with PA Resources (35%) and SNPC (15%). The Azurite FDPSO contract will terminate in April 2014, at least two years early. The FDPSO is the first FPSO with drilling capability.

Nov 2013: SOCO has entered an agreement with PA Resources to farm-in to a 60% working interest as operator in the Mer Profonde Sud permit excluding the Azurite Field. An exploration well will be drilled in late 2014 targeting reservoirs that produce in Congo and Angola. PA Resources retain 25% and the Congolese state oil company, SNPC, retain 15%.
