Principles and Applications of Cased Hole Logging Production and Operations

Hani Elshahawi

Description

This course is designed to provide geoscientists and engineers involved in field development, well construction, or production an overview of the principles and applications of cased hole logging.

The objective of this course is to teach participants when to recommend and how to plan cased hole logs and how to evaluate their results. It will cover tool physics and principles of operation, primary applications and measurements, recommended practices for deployment, and interpretation methodology. Below is a general outline of the course structure:

  • Introduction—terms and definitions
  • The near-wellbore environment and the role of different cased hole measurements
  • Production logging
  • Cement evaluation
  • Corrosion evaluation
  • Cased hole saturation monitoring (pulsed neutron, carbon-oxygen, etc.)
  • Planning, design, and execution aspects of cased hole logs

Why You Should Attend

At the conclusion of the course, participants will be able to understand:

  • common applications of production logging and measurements acquired
  • difference between single phase and multiphase flow regimes and interpretation methodologies
  • uses and limitations of PNC and CO tools and apply Sigma interpretation technique
  • use and limitations of logging standard open hole tools through casing
  • applications of CBL-VDL and ultrasonic tools and in which situations each should be used
  • corrosion monitoring methods and the benefits and limitations of each

Who Should Attend

The target audience includes earth geoscientists and engineers involved in the acquisition, interpretation, or use of cased hole logs. This is a mid-level course that provides a broad overview of cased hole logging methods and practices including production logging, cement evaluation, and corrosion monitoring.

Special
Requirements

  • Portable computer/laptop
  • Participants should have a basic understanding of petroleum engineering concepts
  • Attendees need to bring relevant logs and log evaluation problems to use as in-class exercises
