Wireline and LWD Log Quality Control and its Impact on Interpretation (PPH25)
28 Sep-2 Oct 2020 5 days London, United KingdomCourse Fee: 3490 EUR + VAT
Computer Fee: 250 EUR + VAT
Description
The certification of acquired data is a very critical aspect of wireline and LWD logging and is performed through the observation of key quality indicators. The main objective of this course is to make you aware of these quality indicators as well as the different techniques to solve commonly found issues at the wellsite.
The 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 your knowledge to be able to perform a proper log QA/QC analysis.
This training course will feature:
