This course addresses the key subjects concerning the performance of gas condensate systems from reserve evaluation to production optimisation planning.
Course Level: Advanced / Specialised Instructor: Curtis H. Whitson
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
By the end of the course you will feel more confident in your understanding of:
“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
