COURSE OVERVIEW:

Well Test Analysis in Complex Reservoirs is an advanced program designed for engineers who must interpret Pressure Transient Analysis (PTA) data in non-ideal geological settings. While basic PTA assumes a homogeneous, infinite-acting reservoir, actual field conditions involve faults, fractures, multi-layered zones, and varying boundaries. This course provides the analytical tools to decode these complex signatures and build accurate reservoir models.

The scope of this training includes the study of dual-porosity and dual-permeability models for naturally fractured reservoirs (NFRs). Participants will learn how to identify the characteristic "dip" in the derivative plot that signifies fractured behavior. The curriculum explores the impact of reservoir boundaries, such as sealing faults, constant pressure edges, and channel geometries, teaching attendees how to quantify the distance to these features through pressure data.

Coverage also extends to horizontal wells and multi-layered systems. Attendees will examine the different flow regimes—including early radial, linear, and late radial flow unique to horizontal completions. By utilizing advanced software interpretation techniques, participants will be able to distinguish between wellbore effects and true reservoir behavior, leading to a deeper understanding of reservoir connectivity, drainage volume, and future production potential.

COURSE OBJECTIVES:

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

• Interpret Pressure Transient Analysis (PTA) signatures in complex geologies.
• Utilize the Pressure Derivative plot for advanced diagnostics.
• Model naturally fractured reservoirs (NFRs) using dual-porosity theory.
• Identify and quantify reservoir heterogeneities and boundaries (faults/channels).
• Analyze well tests from horizontal and multi-lateral well architectures.
• Distinguish between wellbore storage, skin effects, and reservoir features.
• Evaluate the performance of multi-layered reservoirs with cross-flow.
• Utilize Deconvolution techniques to maximize the value of long-term data.
• Estimate the Volume of Investigation and Drainage Area from transient data.
• Reconcile PTA results with geological models and seismic data.
• Troubleshoot poor-quality gauge data and identify tidal/environmental noise.
• Select appropriate reservoir models for software-aided interpretation.
• Design complex well test sequences (Interference and Pulse tests).

TARGET AUDIENCE:

Senior Reservoir Engineers, Production Engineers, Geoscientists, and Well Test Interpretation 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.
