LOF Simulation of a Multi-Reservoir Development

This example presents a fictitious multi-reservoir development consisting of four separate reservoirs. The development has two main reservoirs in the South (Pluto and Mickio) which contain the majority of the reserves. However, to the West lie two smaller reservoirs: Donaldo and Minnio. The development plan called for the rapid exploitation of all of the reservoirs through an area wide ‘super-development’.

This system has been modelled in Maximus and simulated for twenty years of production life. The total oil production rate at the FPSO was constrained to 125,000 bbl/d (circa 85,000 bbl/d from the Southern fields and 40,000 bbl/d from the Western fields). The predicted total flow rate, together with the flow rates from the Southern and Western fields, are shown in the second figure. The system maintains plateau production for about 5 years dropping off at a relatively slow rate thereafter. Maximus takes just over 4 minutes to complete the 20 years of simulation.
