PRODUCTION LOGGING

TRAINING DESCRIPTION

The training covers the practical and theoretical aspects modern production logging operations in terms of tool selection and data requirements, measurement limitations, analysis and its pitfalls. In the practical sessions, real field data are analyzed and the results discussed in depth.

OBJECTIVE

This training is designed for engineers and other technical personnel who are involved at any stage in the specification, acquisition or interpretation of cased-hole wireline measurements. The training aims to provide a practical understanding of the physical phenomena involved, measurement principles, equipment types and the analysis of production logging surveys.

TRAINING MATERIAL OUTLINE

• Case Study: Spinner calibration and interpretation in an inclined well, shut in and flowing, layered inflow performance
• Fluid Identification
• Phase hold up by pressure gradient, radio active fluid density and dielectric (capacitance) based methods
• Temperature Measurement
• Main features of temperature profiles in producing and injecting wells
• Anomalous temperature profiles
• Pressure Measurement
• Calliper, Gamma Ray, CCL, and Depth Control: Modern Production Logging Toolstrings
• Two Phase Flow
