Advanced Well Test Analysis

Mr. Saad Ibrahim: P. Eng
(2 days) – TBA

Course Objective:
The objective of this course is to provide an advanced level of the theoretical and practical knowledge of well test analysis techniques. The theoretical aspects will reviewed in a concise fashion, but the emphasis will be placed on the practical aspects of the advanced techniques of well test analysis. Methods of well test analysis using both pressure transient analysis (PTA) and Rate Transient Analysis (RTA) will be illustrated with case study applications to both conventional and unconventional reservoirs, such as the Montney, Horner River, Bakken, etc. Some of the advanced techniques including deconvolution, rate and time-dependent skin factor, multi-phase analysis, and numerical analysis techniques will be discussed. Unique applications will cover modeling of Inflow Control Devices (ICD’s), flow behind casing, multi-layers and multi-laterals. Also the subject of optimizing Multi Stage Frac of Hz Wells (MFHW’s) will be discussed. Hands-on experience will be offered by encouraging the attendees to bring interesting well test data for analysis and discussion in the class, using commercial software. A detailed course hand-out, which is an excellent reference, will be provided.
