ABSTRACT
The recent substantial drop in the oil price has driven the offshore industry to reduce investment costs, especially in the offshore fields.
A case study based on an offshore field for either light or heavy oil is considered. Three alternative subsea layout scenarios have been assumed to perform the relevant analyses that could lead to conclusions associated with the economic feasibility of using the subsea-to-shore concept.The assumed oil field locates at a distance of 100 km from the Brazilian coast at a water depth of 600 m. Production is based on 40 production wells and eight injection wells. Recoverable reserves exceed four hundred million barrels, with an initial and maximum flow rates of 60 and 180 thousand barrels per day, respectively.
