Logs For Drilling Engineers
Objectives:
Have u ever wished there was a logging coarse designed just for you? Drilling engineers don't usually need to know how to interpret open hole logs quantitatively, but they are interested in what logs can tell them about the kind of formations they are drilling and what they contain: they also need to know whether they've made a good job of cementing the casing.
Course outlines:
 
• Mechanism of invasion, invasion profile , and filtrate migration
 
• Electrical properties of earth materials
 
• Resistivity tools- normal, induction, laterolog, micro tools, FMS
 
• Identification of permeable and impermeable zones and skales
 
• Matrix sensitive surveys-GR, SGR, Pe
 
• Depth control
 
• Calipers
 
• Porosity/mineralogy logs density, Neutron, sonic
 
• Mineralogy identification
 
• Porosity determination in clean formations
 
• Recognition of hydrocarbon-bearing zones
 
• Discrimination between oil and gas
 
• Multiple-point pressure measurements and what they mean
 
• Using temperature to find lost circulation zones and cement tops
 
• Cement bond measuring tools-CBL,BCL, cement evaluation , sonic imaging-how they work, what they measure, how to interpret them, why they give different answers
 
• Qualitative and quantitative evaluation of cement bonding
 
• How to prevent micro annulus
 
• Anomalous responses
 
• Causes of cement channels
Who should attend?

Drilling engineers and managers, and anyone needing to know what open hole logs mean and how to run and interpret the various types of cement bond surveys.
