Course Description

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. This course is designed to provide participants with a detailed and up-to-date overview of advanced pressure transient analysis/rate transient analysis (PTA/RTA). It covers the advanced wellbore models and well performance models; the advanced well models; the theoretical derivation and response and comparing this to what happens in the real world; the parameters affecting pressure behavior in horizontal wells including low vertical permeability and partial horizontal drainage; and the advanced reservoir models. Further, the course will also discuss the complex boundary conditions and unconventional limits; the constant pressure boundaries, leaking, conductive and non-continuous faults including finite reservoirs and material balance; the effect of compressibility on reserve estimations and the validity of radius of investigation; the principle and use of the complete production and pressure history in transient analysis; the method for reservoir coupled with limitations and caveats of the method; and developing a consistent workflow combining the G-function plot with derivatives to define the leak-off behavior and the closure pressure including after closure analysis (ACA).During this interactive course, participants will learn to develop the workflow from the simple analytical case through to the numerical case with increasing complexity; use increasing geological and petrophysical data from 2D to 3D and multiphase; compare the information gained from looking at high resolution, high frequency data (PTA) and low-resolution low frequency data (RTA); identify transient versus boundary dominated diffusion; and determine complex PVT covering the multiphase problem, aquifers and the choice and tuning of the model, Non-Darcy flow, heavy oil analysis, gas condensate and using the non-linear numerical model.
