COURSE OVERVIEW:

Pressure Transient Analysis (PTA) is a critical diagnostic tool used to characterize reservoir properties and well performance through the observation of pressure changes over time. This course provides a comprehensive exploration of the mathematical foundations and practical applications of well testing. Participants will learn how to interpret data from build-up and draw-down tests to determine essential parameters such as permeability, skin factor, and initial reservoir pressure, which are vital for accurate production forecasting.

The scope of this training encompasses the evolution of interpretation techniques, from traditional semi-log plots to modern derivative analysis. It covers the identification of various flow regimes—including radial, linear, and spherical flow and explains how these patterns reveal the presence of reservoir boundaries, faults, and heterogeneities. The course also addresses the complexities of analyzing tests in different well types, such as horizontal and fractured wells, providing a robust framework for understanding the subsurface environment.

Integrated into the coverage is the practical usage of industry-standard software for model matching and sensitivity analysis. Engineers will learn how to design effective tests that minimize production loss while maximizing data quality. By combining theoretical derivations with real-world field examples, the course ensures that participants can confidently validate reservoir models, diagnose wellbore damage, and provide the technical justification for well intervention or field development strategies.

COURSE OBJECTIVES:

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

• Identify the fundamental objectives and types of pressure transient tests.
• Derive the diffusivity equation and understand its physical significance.
• Calculate permeability and skin factor from semi-log and log-log plots.
• Utilize the Pressure Derivative (Bourdet) method for flow regime identification.
• Diagnose wellbore storage effects and their impact on early-time data.
• Estimate the distance to reservoir boundaries and faults.
• Analyze pressure transients in fractured and dual-porosity reservoirs.
• Interpret tests from horizontal and multi-lateral well configurations.
• Perform deconvolution techniques to analyze variable rate data.
• Design well test sequences to achieve specific reservoir targets.
• Evaluate the effectiveness of hydraulic fracturing or acidizing through PTA.
• Use specialized software to perform non-linear regression and model matching.
• Determine the average reservoir pressure using the MBH and other methods.

TARGET AUDIENCE:

Reservoir Engineers, Production Engineers, Petroleum Engineers, and Well Test Specialists responsible for interpreting well performance and reservoir data.

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.
