The first is an offshore oil field and thesecond is an onshore condensate reservoir. This paper describes the application of the software to study thedevelopment options of two fields. The software solves the network on the fly as opposed to the network modeloption in Eclipse-200 which uses tables to interpolate the pressure differencesbetween the various nodes.
This allows maximum flexibility in the use of the tool tostudy the performance of the models. It can be run under a maximum deliverability mode. The model canbe run to obey the Eclipse limits or The combined Eclipse-PIPESIM-Net model can be run in either of two modes: Thelinkage is achieved through the PIPESIM-FPT tool of Baker Jardine. There is thus a need to develop a tool that willallow the simulation of surface networks to be linked to subsurface simulationmodels.īHP Petroleum and Baker Jardine have developed a tool for linking Geoquest's Eclipse-100 simulator to the Baker Jardine's network simulator PIPESIM-Net.
The performance made with constant well-head pressure constraints willtherefore be very approximate. With change influid ratios (water cuts, gas liquid ratios etc.) the surface network couldimpose significantly different well head pressures as the field gets depleted.
Unfortunately this could be a serious approximation. Theanalysis of the performance of the surface network was left to the facilityengineers. The influence ofsurface facilities on the sub-surface performance was at best included as lifttables for wells with constraints on the flowing well-head pressures etc. Until recently, reservoir simulation engineers have been modelingsub-surface flow of reservoir with simulators that concentrate mainly on theimpact of subsurface parameters on the production profiles.
