Seismic Data Interpretation and Evaluation for Hydrocarbon Exploration and Production
Young students in universities and freshers in oil companies have asked me on many
occasions after my lectures, if I could suggest a reference book on interpretation and
evaluation of seismic data. I could not do so because, honestly, I was not aware of
any such book. Interpretation, being an aspective art, depends to a large extent on an
individual’s perception and, perhaps due to this reason, it becomes diffi cult for one
to express abstract things in writing.
Interpretation of any data, especially seismic data in petroleum exploration,
needs to be conclusive and logically extended to its geological implications, in evaluating
the prospects for techno-economical risk analysis, and consequently in strategizing
fi eld development plans for exploration and production of hydrocarbons.
There is a difference between interpretation of data and its evaluation, which needs
emphasis. For example, detecting and mapping a fault is not an end of an interpretation
in itself. It is essential for the interpreter to evaluate its signifi cance in terms of
its role in source and reservoir potentials, in trapping and migration mechanisms,
and ultimately for accumulation and production of hydrocarbons.
This guide is for practioners, students as well as geoscientists and engineers in
the industry in the fi eld of seismic data interpretation and more signifi cantly for data
evaluation. It is assumed that the young professionals are well acquainted with the
elementary theory, principles and the equations in their respective disciplines of
geology and geophysics taught in schools, and as such these preliminaries are
mostly kept to the bare minimal. However, as it is essential for a seismic analyst to
be familiar with certain relevant geophysical, geological and reservoir engineering
principles for a holistic interpretation and evaluation of multidisciplinary data, some
of the basics are restated very briefl y and in a simple way in the book for
expediency.
This guide is principally an expanded and enlarged version of my lecture and
training notes to post-graduate students of Petroleum Geology and Geophysics and
young professionals in oil companies. A caveat that may appropriately be stated
here is that the handbook refl ects a fl avor of many of my personal perceptions and
idealistic thoughts, sieved out of many decades of my practicing experiences in
petroleum exploration and development. It is an attempt to encourage and steer
young analysts to become more imaginative, logical, and practical in application of
their knowledge to achieve the goals.
Ultimately, it aims to motivate and facilitate the practitioners in the art of seismic
data interpretation and evaluation and to gain profi ciency in a shorter span of time,
an objective often sought by E&P companies in the industry. It is hoped that this
handbook provides enough stimuli to the inquisitive and sharp minds of the young
geoscientists and engineers, compelling them to continue thinking and questioning
followed by offering rejoinders, and in the process excel in their profession.
