We will be hosting our industry respected Deterministic Petrophysics course in Aberdeen: 1st to 4th of May. Edward Downer will be your trainer!

1. Working together
for a safer world
Aims
Petrophysics is fundamental to
understanding the properties of oil and
gas fields. It lies at the centre of all
subsurface activities: whether in the
context of open-hole operations on new
drill wells, cased-hole operations on
producing wells or in an integrated team
building reservoir models for asset
evaluation, field development or
reservoir management.
In this course, emphasis will be placed
on the integration of all available data,
understanding the context in which the
data are acquired and selection of
appropriate methods and parameters.
Common pitfalls, encountered in the
interpretation process, and their
consequences, will be identified.
Interpretation exercises are an important
element of the course.
Benefits
You will learn:
• The role of petrophysics
• Definitions of the main petrophysical
parameters
• Capillarity, fluid distribution, free
water level and fluid contacts
• Logging tool measurement principles
and the effect of the borehole
environment
• Log data quality assurance
• Quick-look log interpretation
• Data preparation, database
construction and environmental
corrections
• Deterministic petrophysical
interpretation in clean and shaly sands
• Deterministic interpretation in
carbonates
• Reporting and delivering results to
other disciplines
Who should attend?
Reservoir engineers, geoscientists,
petrophysicists and others involved in
the oil and gas subsurface management
life cycle, with some experience in
formation evaluation, who wish to
broaden their practical knowledge and
understanding of petrophysical data
acquisition, quality control and
interpretation. Also numerate graduate
entrants to these disciplines.
Duration – 4 days
Course instructors
This course will be presented by Ed
Downer.
Ed is Discipline Head of Petrophysics at
Lloyds Register (LR) and holds a BEng
(Hons) Chemical Engineering from
Nottingham University and a MSc
Reservoir Evaluation and Management
from Heriot Watt University. He has a
broad background encompassing
operations, training, technology,
software and consultancy.
Following graduation from Nottingham
University in 1996, Ed joined Western
Atlas (now Baker Hughes) as a wireline
field engineer gaining operational
experience in the North Sea, US, West
Africa and the South Atlantic.

Hughes’ Technology Center in Houston
as a technology transfer engineer with a
focus on formation testing and
sampling.
Ed returned to the UK to undertake a
MSc at Heriot Watt. On completion he
joined Senergy (now LR) as a software
development petrophysicist for

Support Manager when Schlumberger
SIS ended a relationship to provide
technical support for IP.
Ed subsequently moved into the
consultancy undertaking petrophysical
field studies and support, and took on
the role of Team Lead. After a brief
move to Baker Hughes as a Senior
Petrophysical Advisor supporting
advanced petrophysics products
(wireline and LWD), he returned to LR as
Discipline Head of Petrophysics.
Ed is also Technical Manager for our MSc
Petrophysics and Formation Evaluation
programme in partnership with the
University of Aberdeen.
The course will be conducted using a
combination of lectures,
demonstrations, interactive learning and
paper/calculator-based interpretation
exercises.
