ONLINE: Wireline and LWD Log Quality Control and its Impact on Interpretation (PPH925)

6-9 November 20234 daysVirtual instructor-led course, OnlineCourse Fee: 1950 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 several 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
Multiple log quality control exercises

Course Structure: 4 modules of max. 4 hours each, delivered over 4 days
Each day will consist of 1 module which will be no more than 4 hours in length with ample time for delegates to break for refreshments.

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 be given in real time through live webinars (instructor-led training); some exercises will be executed during the sessions, others will be done as homework.
The daily sessions will be highly interactive and participative. This involves regular discussions of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.

The benefits from attending

By the end of the course you will feel confident in your understanding of:

Physical principles of main wireline and LWD logging tools
Applying quality control techniques to validate logging data
Main applications and limitations of the different tool readings
How to perform a complete log quality control in a set of logs
How to perform a basic log interpretation
