On 23 October 2017, US Company Hess Corp reported that it is currently selling its 80.75% operated interest in producing Ceiba and Okume Complexes to Dallas-based Kosmos Energy and London-based Trident Energy. The deal, expected to close by end 2017, is worth USD 650 million and will be effective back on 1 January 2017. Contacted, Tullow Oil confirmed that it remains partner with 14.25% interest. CEO John Hess said: âProceeds from asset sales, along with cash on our balance sheet, are expected to fund the development of our truly world class investment opportunity offshore Guyana.â Kosmos proactively enters Equatorial Guinea, as it recently signed a PSC covering the three offshore exploration blocks surrounding Ceiba/Okume producing fields, namely EG-21, Block W and Block S. It is assumed that upon official ratification of the deal, Kosmos will operate the permits with 80% interest, alongside with GEPetrol (20%). In 2016, Hessâ crude oil volumes from Ceiba/Okume Complex (46,250 bo/d) represented almost 30% of total countryâs output. However, the company recorded the largest decrease in production (22% drop from 2015). In 1H 2017, production from Ceiba/Okume continued to decrease to 35,000 bo/d. In 2016, operator ExxonMobil remained the largest producer in Equatorial Guinea (55% of countryâs output) from its Zafiro field. Atlas/Noble produced the remaining 15% of countryâs crude oil, from the Aseng field. Â
