N054 - Intermediate Petrophysics for Conventional Reservoirs

Course Overview
This intermediate, practical petrophysics course explains the physical properties of rocks and their constituent fluids, how their properties are measured (core and downhole), and how this information is used in subsurface studies. Particular emphasis is given to the interactions between rock and fluid volumes, which are explained and then illustrated with real examples. A significant proportion of the class time is spent on petrophysical exercises, covering both clastics and carbonates.

This is an integrated practical petrophysics course, not just another log interpretation session. Topics covered include: physical rock properties, geophysical parameters used in downhole logging, core analysis, fluid distribution, capillary pressure, borehole imaging, log measurements and interpretation. This course does not consider unconventional reservoirs. The application of petrophysical analysis to subsurface projects will be emphasized, and the value of this approach will be illustrated with case studies and exercises. Participants will be taught how petrophysical tools measure parameters related to both lithology and fluids, highlighting the strengths and pitfalls of petrophysical measurements and interpretation.

Participants will learn to:
•	Evaluate the petrophysical properties of conventional reservoirs and the fluids contained within them.
•	Evaluate the basic functions and measurement principles behind each of the primary logging tools and
        selected specialty tools.
•	Analyze and integrate conventional and special core analysis measurements and link them to log data.
•	Evaluate through logs and core the key petrophysical properties such as lithology, porosity, Archie 
        parameters, water saturation, permeability and net sand/net pay.
•	Assess the different modes of shale distribution, estimate shale volume from logs, appraise the different
        shaly sand interpretation models and understand the difference between effective and total porosity.
•	Generate a comprehensive petrophysical evaluation of a drilled section, using an appropriate workflow
        to integrate available petrophysical data from logs and core.
•	Estimate the hydrocarbon reserves in a thinly bedded sand-shale sequence using resistivity anisotropy principles.
•	Consider the primary causes of Low Resistivity Pay and recommend the appropriate tools and measurements 
        for evaluation.
•	Evaluate petrophysical properties and apply interpretation techniques through a series of case studies and 
        practical exercises.
•	Generate a saturation-height model of a heterogeneous reservoir using capillary pressure data.
