Saipem has been awarded contracts for the second phase of the ExxonMobil led Liza development offshore Guyana. These contracts, assigned by Esso Exploration and Production Guyana Limited (EEPGL), an affiliate of ExxonMobil, as the project operator, are in addition to those awarded to Saipem in 2017 for Liza Phase 1.
Following engineering and subject to requisite government approvals, project sanction from the joint venture and an authorization to proceed with the next phase, Saipem will then perform detailed engineering, procurement, construction, and installation of the risers, flowlines, and associated structures and jumpers. Saipem will also transport and install umbilicals, manifolds, and associated foundations for the production, and water and gas injection systems.
Development of the Stabroek Block is being pursued by a joint venture which includes Esso Exploration and Production Guyana Limited as operator and 45 percent interest holder, in conjunction with Hess Guyana Exploration Limited (30 percent interest) and CNOOC Nexen Petroleum Guyana Limited (25 percent interest).
Liza field is located approximately 200 Km off the shores of Guyana in the Stabroek Block at a water depth up to 1,850 metres. The second phase of the development has a larger number of wells and related subsea equipment than its predecessor and will produce an estimated 220,000 BOPD.
“For Saipem this award is significant and strategic, and consistently supports our aim to consolidate our leading position in the offshore Subsea Flowlines Umbilicals and Risers (SURF) market. It also consolidates our relations with an important client such as ExxonMobil and allows us to contribute safely to the development of Guyana’s significant hydrocarbon resources. Finally, this project is expected to involve the recently acquired vessel Constellation which, together with the FDS2, will ensure an offshore execution campaign to achieve first oil by 2022,” Stefano Cao, Saipem CEO, commented.
ExxonMobil initiated oil and gas exploration activities in Guyana in 2008, collecting and evaluating substantial 3-D seismic data that led to the company safely drilling its first exploration well in 2015, Liza-1.
ExxonMobil is now firmly established in Guyana and committed to model corporate citizenship. The Government of Guyana issued the production license for Liza Phase 1 in June 2017 and first oil is expected no later than 2020.
Drilling continues to yield positive results. Longtail, is the latest and eighth oil discovery in the Stabroek Block since Liza in May 2015, when ExxonMobil announced that first significant discovery. Exploration continues. The Stabroek Block is 6.6 million acres (26,800 square kilometres) and located approximately 120 miles (193 kilometres) offshore Guyana. The Liza, Payara, Liza deep, Snoek, Turbot, Ranger, Pacora and Longtail discoveries are located in the Stabroek Block.
ExxonMobil’s affiliate, Esso Exploration and Production Guyana Limited (EEPGL) operates offices in Georgetown. The current staff of the Guyana Affiliate office is 47, 66% being Guyanese. That is expected to increase by the year 2020 with an increase in Guyanese staff. Consistent with its commitment to corporate citizenship EEPGL has established a Centre for Local Business Development to upgrade skills of small and medium sized businesses, and increase their readiness to provide competent local content ahead of first oil.
The Canje Block is located offshore Guyana east of the Stabroek Block, 3-D seismic data was collected in 2016. EEPGL is the operator and holds 35 percent interest, JHI holds 40 percent interest and Mid-Atlantic holds 25 percent interest.
The Kaieteur Block is located offshore Guyana to the north and adjacent to the Stabroek and Canje blocks, approximately 250 kilometres offshore in ultra-deep water, 3-D seismic survey was completed in 2017. EEPGL is the operator and holds 50 percent interest, Ratio Energy Limited holds 25 percent interest and Ratio Guyana Limited holds 25 percent interest.

Liza Phase 2
- EEPGL has started the process for a potential Liza phase 2 development. As part of the regulatory process, EEPGL applied to the Environmental Protection Agency (EPA) for environmental authorization and are progressing planning on a potential production concept for Liza phase 2.
The potential concept involves a second floating, production, storage and offloading vessel (FPSO) and related subsea equipment, umbilical, risers and flowlines. The proposed development concept is similar to that of Liza phase 1. Approximately 35-40 wells may be drilled at two subsea drill centres, consisting of a combination of producers and injectors to support production of oil, injection of water and reinjection of associated gas. The FPSO will have an estimated production capacity of approximately 190,000 to 220,000 barrels of oil per day.
New offshore E&C contract in Congo
Furthermore, through its subsidiary Boscongo SA, Saipem has been awarded a new offshore E&C contract in the Republic of Congo for an MMO (Maintenance, Modifications & Operations) project in relation to the Centrale Electrique du Congo, which covers over half of the country’s electricity supply.
