N649 Introduction to Log Analysis
N649 Introduction to Log Analysis
This three-day course covers the fundamentals of log analysis for understanding openhole logs and teaches immediate practical skills in formation evaluation. Hydrocarbon evaluation, porosity and permeability estimation are covered, together with rock typing and pay assessment. Methods to integrate core data, drill cuttings reports, DST results, and production information with logs are described. Log quality control and normalization issues are also discussed. Participants are required to bring calculator or a laptop computer for all 3 course days - please be sure to fully charge laptop batteries prior to each day. Excel freeware log analysis software is provided.
