Description

Designed for you, if you are...

• An experienced reservoir engineer dealing with the behaviour of condensate systems and wish to refine your expertise in phase behaviour and multi-phase fluid flow

How we build your confidence

• Demonstrations of which gas condensate PVT data are important, and how to use these data
• Using a PVT lab report to develop an EOS or black-oil model for gas condensate modelling
• Quantifying the importance of condensate production and how it can be best forecast
• Fluid characterisation with an EOS using a commercial PC-based program will be performed
• Compositional reservoir simulation exercises are also used to demonstrate key issues for well deliverability and gas cycling

The benefits from attending

• “What’s important and why” about gas condensate PVT behaviour
• PVT lab reports and how to use them
• The quantitative importance of condensate blockage on well deliverability
• When gas cycling is opportune, and when not

Topics

• Introduction and general review of gas condensate reservoir performance



• Sampling methods and laboratory PVT measurements
• Equation-of-state (EOS) fluid characterisation



• Material balance methods including two-phase Z-factor, water influx, trapped gas / condensate and the effect of formation water compressibility



• Long-term well inflow performance, condensate blockage skin and well test interpretation



• Tubing lift performance, minimum lift and erosional velocity
• Special core analysis and relative permeabilities



• Gas cycling considerations, injection patterns, revaporisation and miscibility



• Layered, no-crossflow reservoir and well performance
