4 international context thursday 5h october 2017 Special issue le marin Three areas live up to their promises S ince the world-class oil well Liza was discovered in 2015 offshore Guyana, ExxonMobil has been moving from one successful project to another in this area. The huge potential in ultra deep waters - i.e. 1,500 metres underwater - in the area has been confirmed in recent months. In January, the US group proudly announced the discovery of a new oil field on its Starbroek block, about a dozen kilometres NorthEast of Liza. The new well, Paraya, is located in a deeper reservoir below Liza. Estimated potential: 100 to 150 million barrels of oil equivalent (MBOE). Jackpot in Mexico In March, ExxonMobil announced the discovery of an adjacent satellite well to Liza (Sneok), 9 km South East from the well. In June, the company disclosed positive findings of a new well in the Liza area, Liza-4. This will support a second development phase for this field. Finally, in July, a second discovery was made at Paraya, bringing the resources to an estimated 500 MBOE. 'Paraya 2 confirms the second giant field discovered in Guyana', ExxonMobil happily announced. In light of these new successful wells, the group have estimated the gross recoverable resources at Stabroek to between 2.25 and 2.75 billion BOE. Hence, it comes as no surprise that the group has decided to invest in the Liza development phase this year. Also, it acquired a block in the deep waters of Surinam, Guyana's neighbouring country, in July. Though Apache announced that a dry well was drilled in April offshore Surinam, the GuyanaSurinam basin could hold a few more surprises in store. Another promising area are the Mexican waters in the Gulf of Mexico, now open to international companies following the reform of the energy sector initiated in 2013. In 2015, Eni signed a contract to develop three offshore fields located in the shallow waters of Bay of Campeche. The Italian group was thus the first oil company to operate in Mexico since the 2013 reform. Bingo! The Amoca-2 well identified new resources on the Amoca oil field, as announced by Eni in March 2017.

Some have led to new - and substantial - discoveries in 2017, like those in Guyana, Mexico and Burma. ExxonMobil used the 'Stena Carron' drillship in Guyana. ter. As a result, the group now estimates the resources on the field to one billion BOE. Potential in Burma In July, Talos Energy made 'a world-class oil discovery' on the Mexican block 7, also in shallow waters. The resources on site are estimated to over one billion barrels. This will prompt companies to take part in the licensing round for deep waters that Mexico plans to hold in January 2018. Finally, one last zone is worth mentioning offshore Burma, where Australian company Woodside has announced a third discovery in August, following those of 2012 and 2015. The Pyi Thit-1 well was drilled on block A-6, of which Total E&P Myanmar holds 40%. Considering the offshore gas potential, Burmese authorities have approved the construction of an offshore supply platform by Singapore company MOSB that will be located at Mawlamyine, on the southeastern coast. Anticipated investment: $118.5 million. Carole LANZI Eni wants the jackpot in Mexico *Following the results on the Mexican field Amoca, Eni is looking to step up development of the field, with a view to starting production in early 2019. The production plateau should range between 30,000 and 50,000 barrels per day. The Italian group's objective is to be the first international company to produce as operator in Mexico. Amoca, located in shallow waters, offers a higher break-even level. According to Eni, 'Considering the low oil prices, this is the ideal project'. production to start at Liza in 2020 *TheGuyana: first development phase of the Liza field in Guyana will use an FPSO that can produce 120,000 barrels of oil per day. Production is due to start by 2020. The cost of phase 1 is estimated to over $4.4 billion. The field is located 190 km offshore, at depths between 1,500 and 1,900 metres. ExxonMobil plans to pursue its exploration work in Guyana in 2018.
