**Basic Well Test Analysis**

**Saad Ibrahim, P. Engineer**

(3 days) – May 3-5, Sept 20-22, 2021

**Course Objective:**

The objective of the Well Test Analysis Workshop is to provide a comprehensive theoretical and practical knowledge of well test analysis techniques. Emphasis will be placed on the practical aspects of well testing and several class examples will be offered; a scientific hand calculator will be required. Further, the use of the analysis results as a reservoir management tool to make decisions related to reservoir development and well completion will be illustrated through actual case studies throughout the workshop. Recent developments in the testing of Multi-stage Frac of Horizontal Wells (MFHW’s) and Mini fracing (DFIT) are now included. Also, to offer hands-on experience, attendees are encouraged 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.
