Eclipse Core Simulator
Multicomponent reservoir fluid description for compositional changes associated with depth, condensates, or volatile crude oils, gas injection programs, and secondary recovery studies
Eclipse advanced wells (multisegment)
Realistic modeling of highly deviated, horizontal, and multilateral wells with advanced completions and inflow control devices
Overview
Seasonality profile
The well trajectory is discretized into a series of segments that are linked together into branches.
Branches can, if required, have sub-branches.
Improved modeling of multiphase flow
Use of the drift-flux model or precalculated pressure drop tables can produce more accurate pressure gradients than the homogeneous flow treatment used in other well models.
The pressure gradient can vary from segment to segment throughout the well and is calculated fully implicitly in each segment using the local flowing conditions.
Applications
Benefits
Modeling of flow control devices
Specific segments can be configured to model flow control devices, such as chokes and valves. The Eclipse simulator contains many built-in devices such as flow limiting valves, labyrinth devices, and downhole separators—other devices can be modeling by providing a pressure drop table which describes its pressure loss characteristics.
Features
Improved wellbore storage modeling
Wellbore storage effects can be modeled more accurately using the segment structure. The drift-flux model allows phases to flow in opposite directions at low flow rates so that phase redistribution within the wellbore can occur during shut-in well tests.
