Presenter
By Dr Deva Ghosh Professor in Geophysics and
Head of Center of Seismic Imaging & Hydrocarbon Prediction
Professor Dr Deva Prasad Ghosh obtained BSc. In Geology and Physics, MSc. in Geophysics both from
Banaras Hindu University India and Ph.D. (1970) from Delft University, the Netherlands.
Prof Deva joined PETRONAS in 2000 and was responsible for research,
development, and application of geophysical technology worldwide. In
2011, he joined the Universiti Teknologi PETRONAS (UTP) as a Professor
in Geophysics and currently responsible as Head of Center of Excellence
in Seismic Imaging & Hydrocarbon Prediction (CSI). He is passionate
about geophysics, developing local staff, and transfer of technology.

INTRODUCTION TO OIL AND GAS
WITH EMPHASIS IN

OUTLINE
Global oil & gas industry has a bright future, even in the backdrop of uncertainty and volatility in the
market. There is an everlasting need of energy demand in the light of prosperity and industrialism. The current
oil demand is around 74 mbbl/day and more exploration for new reserves increased production needed to sustain
the growth. Currently the oil production can easily meet this demand and is somewhat controlled by the group
of Oil Producing and Exporting Countries (OPEC). An overproduction caused mainly by non OPEC countries is
good depending whether you are a producing country or not. This supply and demand controls the oil prices. The
prices have dropped significantly from US$110/barrel to about US$50/barrel. This price drop will benefit nonproducing countries like Japan and India.
During the last decade we have seen unprecedented growth of wellness, prosperity and industrial growth.
The driver of this revolution in prosperity is ‘Energy’ that sustains our civilization. In spite of the global turmoil,
the world energy demand still remains relatively stable. Fossil fuels continue to be the main driver for the energy, while other sources of energy, although promising, is still in the drawing board and is something not economically viable. The rapid pace of economic growth is predicted to require at least 50% more energy than we need
today in a span of 25 years.

Hydrocarbon Prediction from
Seismic
INTRODUCTION
Since the advent of the bright spot DHI technology in the early 80’s, in the Gulf of Mexico prospect
evalution and reservoir development using amplitudes, or some form this attribute, is a norm in the oil and
gas industry and Petronas is no exception. Most of the experience and rules to circumvent pitfalls were
practiced elsewhere and are not always applicable to our situation. In order to better understand these pitfalls, this work documents some of our successes and failures and analyse the pitfalls.
This talk will deal with the interpretation of observed seismic reflections amplitudes in terms of :
(a) Lithology
(b) Porefill
A whole review will follow on techniques such as AVO, Inversion and Rock and Fluid properties of Hydrocarbon bearing reservoir. We will learn the meaning and concept of the DHI. (Direct Hydrocarbon Indicators)
CONTENTS
(I) Factors affecting seismic
amplitudes.
(II) Understand the significance of the amplitudes vs.
offsets.
(III)To distinguish between:
I. L i t h o l o g y
and
porefill
II. Calibrate amplitudes in term of
oil, gas and water
III. Understand and
identify pitfalls
leading to false
DHI.
