| Abstract |
Over
the past two decades, BP has developed workflows to make
predictions about lithology and fluid from seismic amplitudes.
Their current form, which has stabilized in recent years,
is based around a few fairly simply steps: two-term AVO
coordinate rotations, spectral shaping derived from a
power-law Earth spectrum model, and map-based detuning
and calibration. These are underpinned by careful conditioning
of the seismic and by close integration with petrophysical
rock property analysis.
These processes have evolved to meet a number of criteria:
(1) robustness and repeatability,
(2) avoiding parallel
workflows by integrating within existing practices, and
(3) allowing most steps to be carried out by nonspecialist
geophysicists.
Achieving robustness is also a prerequisite for making
uncertainty estimates, which has many potential benefits:
ranking the sources of uncertainty; validating our prediction
models; providing a framework for integrating with other
data types; and helping to understand the theoretical
limits of seismic prediction.
In this talk, I’ll outline the concepts behind the
main steps in the seismic characterization workflow and
discuss approaches to uncertainty estimation.

Biography |
| 
Patrick
Connolly graduated from Birmingham University
with a BSc in physics in 1977 and joined Seismograph
Service Ltd as a data processor. After working in Oman,
New Zealand, Pakistan, and London, he moved to Britoil
in Glasgow in 1982 and worked as a seismic programmer
until the company was acquired by BP in 1989.
Connolly has remained with BP as a seismic analyst and
occasional interpreter in Aberdeen, Houston, and London.
He has been a member of a number of exploration and
appraisal teams: Foinaven and Schiehallion (West of
Shetland), Holstein (Gulf of Mexico), and Greater Plutonio
(offshore Angola). Since 2001, he has worked in BP’s
E&P Technology division and currently is manager,
Seismic Reservoir Characterization and Surveillance
R&D.
Patrick was awarded the SEG Virgil Kauffman Gold Medal
in 2001 for his development of elastic impedance technology.
He was an EAGE distinguished lecturer in 2007.
