COURSE OVERVIEW:

Formation Evaluation (FE) relies heavily on high-quality wireline and logging-while-drilling (LWD) data to accurately determine lithology, porosity, saturation, permeability indicators, and reservoir potential. Poor-quality logs introduce uncertainty, reduce confidence in petrophysical interpretation, and may lead to incorrect reservoir decisions.

This course provides a comprehensive understanding of Log Quality Control (LQC) workflows, tools, and interpretation techniques required to diagnose, validate, and correct logging data. Participants will learn how to identify operational issues, tool malfunctions, borehole effects, environmental corrections, depth mismatches, and unrealistic response behaviours across major logging suites (GR, resistivity, density, neutron, sonic, image logs, and NMR).

Through detailed modules and case-based exercises, the course equips engineers, petrophysicists, and geoscientists with the skills needed to ensure data integrity, improve log reliability, and support high-confidence formation evaluation.

COURSE OBJECTIVES:

After completion of the course, the participants will be able to:

• Understand the role of log quality control in formation evaluation.
• Identify key sources of measurement error in wireline and LWD tools.
• Recognise borehole environmental effects and their influence on log readings.
• Perform depth alignment and log correlation between multiple runs.
• Evaluate tool performance using real-time and recorded diagnostics.
• Identify washouts, borehole ovality, and rugosity impacts on logs.
• Conduct quality checks on gamma ray, resistivity, density, neutron, and sonic logs.
• Assess image log quality and apply corrections for tool eccentricity and stick-slip.
• Evaluate NMR log data quality and identify acquisition issues.
• Understand environmental corrections and compensation algorithms.
• Detect tool failures, calibration issues, and telemetry problems.
• Apply workflow processes for LQC before, during, and after logging runs.
• Integrate LQC results into petrophysical interpretation.
• Review real case studies demonstrating log failures and corrective actions.

TARGET AUDIENCE:

• Formation evaluation engineers
• Petrophysicists
• Geologists and geoscientists
• Logging engineers (wireline and LWD)
• Reservoir engineers
• Wellsite geologists
• Drilling and subsurface engineers requiring LQC competency

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
