Course Description
This 2-day Cement Log Evaluation workshop will illustrate the application of log investigations for cement evaluation, which is essential to successful completions and meeting AER and other provincial requirements.

Actual log examples of SAGD and Horizontal wells will be used to illustrate different types of logging environments allowing comparison for log quality and evaluation of interpretation techniques.

Exercises to determine intervention for Surface Casing Vent Flow issues will be demonstrated. Types of mud removal techniques used and their effects on cement quality will also be discussed.

To "cement" student learning, a practical guideline will be presented to successfully evaluate cement integrity and vertical hydraulic isolation.

Stuart Smith, P.Eng.
As a Professional Field Engineer, Wireline Supervisor, and Log Analyst that is acutely aware of the demands placed on field personnel, Stuart Smith’s mantra is “Call me if you think I can help”.

With over 30 years of domestic and international experience in offshore with semi-submersibles and jack-ups and onshore with triples to poles and slant rigs in both open and cased-hole environments, Stuart Smith’s experience includes vertical and horizontal wellbore surveying and BHA guidance using Magnetic Steering Tools and Gyroscopes. This experience has created a passion and deep understanding for the wellbore and formation investigation sciences with relentless regard for accuracy and consistency.
With over a decade of experience in both cased-hole well integrity log analysis using electromagnetic phase-shift and decay methodologies, and in the evaluation of conventional cement bond logs and acoustic impedance logs Stuart has developed 3-detector cased-hole gamma density porosity algorithms accepted as a replacement for the same measurement in open-hole.

Stuart has also developed a conventional bond log cement evaluation model used successfully on more than 700 SAGD wells in 10.75” and greater casings and more than 500 wells in casing sizes from 4.5” to 9-5/8”. The model has been used successfully since its development in 2013 and works equally well for lightweight and foam cement.

With a Bachelor of Civil Engineering from Western University, and fluency in Spanish Stuart Smith currently works as a log analyst with Multiline Wireline Services Ltd. and has been a P.Eng. member of APEGA since 1992.
