Advanced Production Logging and Cased Hole

About the Course

This 5-day interactive Advanced Production Logging and Cased Hole training course will cover a wide range of knowledge in production logging topics with a particular focus on PLT measurement tools and interpretation in addition to basics of conformance techniques and tracer technologies. It instils the delegates on the use and limitations of various production logging tools, including spinner, temperature, noise, fluid injections, and other tools. They will learn what results these tools yield, the interpretation assumptions that are integral to their designs, and how quality is affected by the acquisition process. Delegates will also acquire the fundamentals of production log interpretation with hands-on examples and an in-class workshop on interpreting single and two-phase flow using production logs. They will learn how the production logs can be used to measure 3-phase fluid flow. 

Likewise, it will also illustrate some theoretical classroom sessions, providing a combination of presentations and animations. The delegates will then have practical examples by workshop exercises during the programme. It will touch on fundamentals of E&P companies’ lifecycle, addressing basic concepts of geology, reservoir-engineering concepts (e.g. field development plans, steady state & unsteady state flow, good water and bad water), petroleum engineering concepts (nodal analysis, IPR & OPR, flow regimes, and formation damage).

Core Objectives

The delegates will achieve the following objectives:

• Know the use of production logs to measure two-phase flow rates (water/oil, oil/gas, water/gas) and three-phase flow rates
• Understand the use of production logs to determine the productivity index (PI) of oil wells and the injectivity of water wells, zone by zone
• Evaluate casing integrity and cement-casing bond using the production logs
• Monitor reservoir development during production using time-lapse logs
• Identify and quantify interzone crossflow
• Develop the skills to design and implement production logging programs to optimise well performance and maximise recovery

Training Approach

This training course will be conducted through classroom or virtual training in interactive and practical methods. There will be daily individual exercises, and everyone will get an opportunity to discuss their issues with the software or with the concept itself. There will be a PowerPoint Presentation to capture all notes and explain everything in detail, and a daily recap will be provided for maximum benefit for the delegates.
