THE
IMPERATIVE:
Structural
geometry frequently gives rise to geologic complexities that
are difficult to understand, nonetheless these are key to
the commerciality of hydrocarbon fields. By reviewing and
analysing structural interpretations we can help to identify
and reduce uncertainties and risks, impacting on reserves
development and future drilling. This identification of alternatives,
options and risks is key to a project's success.
Gains,
outcomes and deliverables:
Our
clients have felt tremendous benefit from engaging in this
process. Significant breakthroughs are often achieved in a
small space of time.
The
principal gains for you the client are:
• A more consistent and robust geometry for the interpretation
of fields where geological complexity has been encountered.·
•
Solutions to
moving forward from drilling surprises and failures.·
•
Identifying new
models for structural and stratigraphic geometries.·
•
Reducing uncertainty
and risk in fields with challenging and complex geology.·
•
Getting a sharper
view of reserve potential in this setting· New thinking
with new ideas on field geometries
•
Solutions to
improved reservoir mapping in difficult areas.
Some
examples from previous projects are as follows:
•
Recognition that
a prospect closure could be much larger than mapped gave confidence
to the client to proceed with the project- subsequent drilling
proved this and resulted in a large oil discovery and commercial
gain for the client.
•
Recognition of
complex structural compartmentalisation of an oil field prior
to development drilling, permitting a better commercial exploitation
of the field reserves
•
Providing input
that resulted in a significant equity swing in favour of the
client.
•
Developing a
new model in an existing oil field where drilling surprises
had occurred., and developing a new realistic framework for
reserves estimation and production drilling
•
Generating a
structural framework that reduced risk and uncertainty in
planning and drilling horizontal development wells, providing
a significant commercial benefit to the company.
What
we do:
•
Review
the project data and interpretation.· Use seismic together
with well ties, drilled sequences, pressure data and oil-water
contacts., to understand the whole picture of the field
•
Iterate through
the interpretation numerous times, picking up uncertainties
and inconsistencies.
•
Discuss issues
and interact with your project team.· Develop a consistent
framework for the interpretation of your oil field.
•
Use experience
from a wider spectrum of areas other than the project to broaden
the thinking and ideas that go into solving your problem.
•
Look at alternative
ways of interpreting the data, and look at opportunities that
may be present for breakthrough, cost saving and value generation.
•
Present key solutions
and results to you
BENEFITS:
The
simple expedient of bringing in an outside person with considerable
geological experience can provide value through the following:
•
An outside view
with experience from numerous basins and oil fields worldwide
that gives a sounding board for your project.
•
Integration of
seismic interpretations, well data and stratigraphic information,
taking an independent view of the field and constraining reserves
and drilling.
•
Evaluating past
drilling surprises and preventing future ones.
•
Generating a
robust regional framework for your field within which in-field
interpretations can be consistently made.
•
Specific focus
on the significance of geological uncertainties
It
is quick, easy and cheap to implement this process. Reviews
and audits can run from a few days to a few weeks
