The importance of being early

 By Eniday Staff

A few weeks ago, Eni anticipated the production start-up in Indonesia and the same has occurred offshore Ghana, thanks to a unique ability to explore, discover and develop in record time, while optimising both costs and timing. Ghana is the best example of the Eni model in Africa and not only that: the speed with which we move from discovery to production, the development process phases, the synergy with the existing facilities and/or the conversion of decommissioned plants. Besides this, there is also a special focus on the communities and local development; not merely with a compassionate, not a “hit and run” approach, but one capable of driving a genuine sustainable development of the domestic market…

OCTP (Offshore Cape Three Points) is an integrated offshore development project, with a start-up previously scheduled for June 2017 and then anticipated in the weekend of 20-21 May, less than 3 years after the final investment decision (December 2014) and with a record time-to-market. OCTP is located in deep waters about 60 kilometres off the coast of western Ghana. The project integrates the development of oil fields in 2 phases, with volumes of about 500 million barrels, and non-associated gas fields of  41 billion cubic metres (approximately). The gas will be entirely dedicated to the domestic market for production of electricity power.

In particular, the oil field was discovered after the gas ones and at a deeper level, thanks to improvements achieved in the advanced seismic imaging systems. The subsequent oil development was in fact based on just 2 discovery and appraisal wells, thanks to advanced seismic and field modelling technologies. Furthermore, through 23 subsea wells to be attached to the FPSO “John Agyekum Kufuor” and a gas pipeline, which will connect the FPSO to the coast, the OCTP project will be able to provide gas for Ghana’s thermal power plants for more than 15 years, making a significant contribution to the energy needs and economic development of the country. In short, following the launch of Jangkrik in Indonesia and the East Hub in Angola, Eni accomplishes in the first half of 2017 another record in terms of time-to-market.

Having illustrated what the offshore OCTP project is, it needs to be explained the FPSO “Kufuor”itself. This converted former oil tanker has the name of the President of Ghana, John Agyekum Kufuor, who has given new impetus to the exploration industry and who awarded the field licence where the vessel has started operating since year 2001. Built in Singapore, from the cooperation among Eni, the Ghana National Petroleum Corporation, Vitol and Yinson, in just 24 months, this “gentle giant”, after a long ocean voyage, arrived in the Ghana offshore to produce oil 333 333 metres long, 58 metres wide and weighing 69,000 tons, the vessel has been designed to minimise the environmental impact. Part of the gas extracted from the fields will be used onboard the ship, which, in terms of energy needs is independent.  The complexity of the vessel is linked to the production double track as well as to the treatment of hydrocarbons. As a result, the vessel can treat simultaneously both oil and gas coming from two near but distinct fields, splitting the associated gas from the oil, and eliminating all traces of liquids from the gas. Only physical treatments will take place on board the vessel, i.e. status, pressure, temperature alterations, to ensure that both oil and gas are transportable. The oil will then be loaded onto shuttle tankers, while gas will be exported via a 70-mile long subsea gas pipeline.

Eni’s presence in Ghana is far more complex, is not just a business activity. In line with the company’s tradition of listening to the needs of local communities, the “Cane a sei zampe” (Six legged dog)  has been long involved in a number of important sustainability projects. From Education to the Environment and Health. Development as a matter of fact, is either a a joint effort or isn’t.. “We grow if the countries that host us grow,” as Claudio Descalzi always says. In Africa and else where.
