Wireline and LWD Log Quality Control and its Impact on Interpretation (PPH25)

25-29 November 20245 daysVienna, AustriaCourse Fee: 3750 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:

Explanation of petrophysical concepts and techniques
Discussions on tools physical principles, applications and QA/QC
Tool limitations on different borehole environments
Metrology concepts and applications on wireline and LWD logs
Multiple log quality control exercises

COMPUTER REQUIREMENTS: MS Office, Excel
Participants are welcome to bring their own laptops to class.

Course Level: Foundation / Skill
Instructor: Angel Meso

Designed for you, if you are...

An engineer in exploration and production departments
A geologist, geophysicist or petrophysicist
A petroleum, reservoir or drilling engineer
In general, any other oil & gas industry professional involved in logging data QA/QC and validation

How we build your confidence

This training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented, the sessions will include visual, auditory and kinesthetic elements to cover the three different learning modalities. The daily sessions will be highly interactive and participative. This involves regular discussion of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.
