Why Choose this Training Course?

The certification of the acquired data is a very critical aspect of wireline logging. It is performed trough the observation of key quality indicators, the main objective of this course is to make all participants aware of these quality indicators as well as the different techniques to solve commonly found issues at the wellsite. This PetroKnowledge training course is intended for oil industry professionals who needs to deal with wireline logs QA/QC in their daily job.

The training course will explore the tools response explained from their physical principles as well as their relationship with the rock and fluid properties, most common open hole logging technologies will be covered explaining their main applications and limitations. Basic petrophysical interpretation will be discussed with numerous examples and exercises in order to complement the participants’ knowledge to be able to perform a proper log QA/QC analysis.

This training course will feature:
