Well Test Interpretation Using Numerical Simulation
This course is designed for engineers and earth scientists with knowledge of the basics of well transient testing and it discusses the use of the latest developments in data measurements and combined analytical and numerical analyses to properly characterise oil and gas reservoirs.
- Multiphase Flow – Gas Condensate Reservoirs: Gas condensate phase behaviour, liquid dropout curves, two-phase pseudo pressure, well deliverability, radial composite behaviour, liquid drop-out skin, design of condensate well tests, field examples, application of compositional reservoir simulation.
- Radial Composite Systems: Falloff tests in water injection wells, radial composite behaviour, derivative diagnostic response, tight inner and tight outer systems, geological origin of radial composite behaviour, application to aquifer influx, compartmentalised reservoirs.
- Numerical Techniques in Well Test Analysis: Numerical solution of diffusion equations, finite element method (FEM), automatic gridding, limited extent baffle, fault systems with windows, layered systems, field examples, gas storage field example.
- Interference Testing: Observation well response, infinite homogeneous system, time delay effects, design of interference tests, application of permanent downhole gauges (PDG), famous derivative spike, and interference testing in faulted systems, vertical interference testing, wireline formation testers with multiple probes, application of numerical solutions.
Who Should Attend
Production and reservoir engineers and earth scientists involved in well and formation characterisation, evaluating reserves, and reservoir surveillance. Participants should have knowledge of the basics of well transient testing.
Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and/or certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDH).
Attendees of SPE training courses earn 0.8 or each day of training. We provide each attendee a certificate upon completion of the training course.
George Stewart is currently chief reservoir engineer for Weatherford and professor at Heriot-Watt. He was a founding member of the petroleum engineering department at Heriot-Watt in 1975 and was also the second Head of Department from 1982-1987. Stewart was also a founder of EPS Ltd and chairman from 1987-2004. In 1976, he was visiting professor at the University of Texas at Austin. He also worked as senior reservoir engineer with Schlumberger from 1978-1982, where he specialised in wireline formation testing.
Stewart has published many papers on well and formation testing and offers courses throughout the world. Recently, he authored two textbooks published by Pennwell: “Well Test Design and Analysis” and “Wireline Formation Testing and Well Deliverability”.
