IME

XIMEX is a full-featured three-phase, four-component black oilreservoir simulator for modelling primary depletion andsecondary recovery processes in conventional oil and gasreservoirs. IMEX also models pseudo-miscible and polymerinjection in conventional oil reservoirs, and primary depletionof gas condensate reservoirs, as well as the behavior ofnaturally or hydraulically fractured reservoirs

IMEX has the capabilities and features required for small to massive (100+million grid block) simulations for screening prospects, setting up pilotdesigns, monitoring and optimizing field operations, and complex full-field reservoir studies, all with the objective of improving productionrates, ultimate recovery and value. The coupling of IMEX to surfacepipeline network simulators provides a very effective solution foroptimizing production from multi-field offshore developments or fromlarge gas fields in which surface flowline constraints can affect reservoirperformance and project economics.

Advanced Features ofIMEX include:

Pseudo-miscible and Polymer InjectionModelling

• Pseudo-miscible fluid injection - solvent solubility in water, chase

gas injection- first contact miscible (Todd and Longstaff)

• Polymer injection - aqueous phase viscosity increase- polymer adsorption and dispersion- absolute and relative permeability reductions

Advanced Well Modelling and WellManagement Features

Well Modelling

• Fully implicit source/sink well model • Vertical, inclined, horizontal and multi-lateral wells• Horizontal wellbore friction pressure drop• Wellbore crossflow• Wellbore fluids mixing with full material balance

Well, Well Group and Surface Manifold Controls

• Pressure, rate, and ratio constraints for surface (tubing head) or downhole conditions

• Automatic switching criteria• Alternative remedial actions • Injection and production manifold controls

Surface Network- Reservoir Model Coupling

• Surface network modelling software that can be run coupled to IMEX

- FORGAS - from Neotechnology Consultants Ltd.

- GAP - from Petroleum Experts, Ltd.• Single or multiple reservoirs • Time-step level coupling • Field development scheduling controls and

constraints • Multi-phase flow in both the gathering

system and wellbore
