SUBJECT : APPLYING STRUCTURAL EVOLUTION TO EVALUATION
OF PETROLEUM SYSTEM
SPEAKER : DR. Alan Gibbs, Midland Valley Exploration,
Scotland
BIOGRAPHY
Dr Alan Gibbs has extensive experience in applying new concepts of
structural evolution to petroleum systems in many basins around the world.
He studied under John Ramsay in Imperial College, then completed
a PhD study in West Greenland before taking up a lecturership in the
University of London.
He is a visiting professor in the University of London Royal Holloway
College
and has published extensively on the structural aspects of basin formation.
In 1980 he joined the British National Oil Company as a structural
geologist
working in Reservoir Engineering, where he identified the role of transfer
faults
in reservoir compartmentalisation. In 1984, Dr. Gibbs founded Midland
Valley
as a centre of global excellence in software tools and consultancy for
structural analysis.

ABSTRACT
Areas where structural evolution has modified 3D hydrocarbon fairways
through time
present a major challenge to understanding petroleum systems. Inversion,
salt tectonics,
or thrust faulting may lead to complex changes that become critical factors
in risking
the hydrocarbon system. To tackle this problem, it is necessary to
integrate the structure model
and its evolution through time with the development of both the sedimentary
system
and the migration and focusing of hydrocarbon fluids. Timing and changing
geometric
configuration are key issues, which can be tackled using an integrated
workflow.
This approach provides the ability to identify and assess risk in
hydrocarbon systems
and to generate multiple scenarios. It provides improved input into 2D and
3D basin modeling
and allows the key system components to be integrated through deposition,
faulting and folding, and migration of hydrocarbon fluids.
3D interpretations are used to generate a basin model that is back-stripped
through time.
This provides the basis for modeling sediment pathways and fluid migration
fairways
at each increment in time. As the model runs forwards through time,
sediment accommodation
space and sediment transfer are analysed. These factors are integrated
with the depositional
model, allowing subbasin spill-ways, stacking patterns, and migration of
depocenters to be identified.
Basin modeling then provides inputs to identify kitchen areas and to define
timing of migration pathways
and hydrocarbon charge. Fluid focusing and drainage cell analysis can then
be evaluated,
and models for fault seal or non-seal and reservoir compartmentalization
can be investigated.
Results of this analysis can be used to develop and condition detailed 2 or
3D basin models,
or they may be applied directly to exploration decisions. This approach has
worked successfully
for projects in the North Sea, deep water Gulf of Mexico, Central and South
America,
North Africa and the Atlantic margin. It demonstrates clear benefits in
significantly
reducing work cycle times, and it provides technical results that differ
significantly
from conventional approaches that do not include effects of lateral
displacements
through time during structural evolution of the basin.
