COURSE OVERVIEW:

Well Testing Design, Analysis, and Interpretation is a fundamental program for engineers who rely on dynamic reservoir data to make multi-million-dollar development decisions. A well test is the only way to observe the reservoir in action, providing critical information on permeability, reservoir boundaries, and well productivity that static logs and seismic data cannot reveal. This course guides participants through the entire lifecycle of a well test, from the initial selection of gauges and flow sequences to the advanced interpretation of pressure transient data.

The scope of this training includes the mathematical foundations of Pressure Transient Analysis (PTA), focusing on the use of the pressure derivative to identify reservoir models. Participants will explore different test types, including Drawdown, Build-up, Interference, and Injection tests. The curriculum emphasizes the "Design" phase, teaching attendees how to ensure the test duration is sufficient to reach the reservoir features of interest while minimizing flared volumes and operational costs.

Coverage also extends to the practicalities of field execution and data quality. Attendees will learn how to identify wellbore storage effects, quantify skin damage, and recognize the signatures of faults and heterogeneities. By mastering modern interpretation software and analytical techniques, participants will be able to transform raw pressure data into actionable insights regarding drainage area, connectivity, and the long-term commercial potential of the asset.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the objectives and types of well tests used in exploration and production.
• Design a well test sequence (rates and durations) to meet specific reservoir objectives.
• Calculate the Productivity Index (PI) and Absolute Open Flow (AOF) potential.
• Analyze Pressure Build-up (PBU) tests using Horner plots and Derivative analysis.
• Quantify the Skin Factor and identify the components of wellbore damage.
• Estimate reservoir properties including Permeability-Thickness and average pressure.
• Identify reservoir boundaries such as sealing faults, channels, and constant pressure edges.
• Distinguish between wellbore storage effects and true reservoir response.
• Utilize Nodal Analysis to reconcile well test results with production performance.
• Evaluate the quality of data from electronic memory gauges and permanent downhole gauges.
• Design and interpret interference tests to determine inter-well connectivity.
• Select appropriate reservoir models (Radial, Linear, Dual-Porosity) for interpretation.
• Prepare a comprehensive well test report with clear technical recommendations.

TARGET AUDIENCE:

Reservoir Engineers, Production Engineers, Petrophysicists, and Well Test Specialists.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
