D054 Skilled Petrophysical Methods for Conventional Reservoirs
Business Impact: Application of the learnings of this course will empower participants to better understand reserve estimation and reservoir characterization of conventional reservoirs.
This intermediate level petrophysics course explains the physical properties of rocks and their constituent fluids, how their properties are measured and how this information is used in reserve estimation and reservoir characterization of conventional reservoirs. Particular emphasis is given to the interactions between rock and fluid volumes which are explained and then illustrated with real examples. The course explores some of the newer generation tools and methods used in formation evaluation. The class consists of both lectures and exercises which are demonstrated with petrophysical software.
A virtual workshop divided into 6 three to three and a half hour webinar sessions (equivalent to a three-day classroom course), comprising a mixture a lectures and log based interpretation exercises demonstrated with petrophysical software.
Participants will learn to:
This is an integrated practical petrophysics course, not just another log interpretation session.Topics covered include: physical rock properties, fluid distribution, capillary pressure, log measurements and interpretation, rock typing for reservoir characterization, Low Resistivity Pay. 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.
The course covers:
Introduction
Shaly Sands and Thin Beds
Nuclear Magnetic Resonance (NMR) measurements
Permeability and Rock Typing
Low Resistivity, Low Contrast Pay (LRLC)
The course targets geoscientists and engineers with 4 or more years of industry experience who work with petrophysicists in regional evaluations, prospect generation and development studies, as well as petrophysicists with 1 to 2 years of experience seeking to enhance their interpretation skills.
Prerequisites - Participants should have a basic understanding of petrophysical evaluation, as presented in N083 (Introduction to Petrophysics and Formulation Evaluation), N121 (Modern Petrophysical Well Log Interpretation) or N003 (Geological Interpretation of Well Logs), as well as practical experience working with well logs.
Linking petrophysics courses include N187 (Low Resistivity Low Contrast Pay, US only), N267 (Petrophysics for Shale Gas, US only) and the field course N030 (Rocks and Fluids: Practical Petrophysics, Isle of Wight, UK)

Background
David joined Shell Offshore in New Orleans, Louisiana as a petrophysicist where he had various assignments in production and exploration, covering all areas of the Gulf of Mexico. He worked for Pecten International, Shell’s global affiliate, in 1994, and focused on exploration in West Africa. In 1996, he moved to Shell’s South Texas Gas Asset team and worked on the development of Wilcox tight gas sands. From 1999 to 2011, David worked with Marathon Oil Corporation where he had exploration/operations assignments for Gulf of Mexico and Angola and a field development assignment for a Sirte Basin discovery in Libya. David retired from Marathon in 2011 and is now teaching industry courses.
David has a broad range of interests within petrophysics, but specializes on the elastic properties of rocks and how seismic attributes can be used to explore for and develop hydrocarbon reservoirs. Other areas of interest are compaction and quartz cementation modeling of clastics for reservoir quality prediction. He has extensive experience in log and core data acquisition as well as reservoir characterization.
