Super Basins 14: Adroit use of Attributes/AVO from Exploration 3D

Lunch'n Learn....what does it look like? 0

Friday, February 17, 2023, Webinar, Online

Last week (5th December) I was at an amazingly well-attended BP Geoscientists reunion. In the course of it I was reminded of a couple of things:

Firstly that it was once expected/demanded that the company did not ‘miss out’ on any major new basin anywhere in the world. It did seem like this no longer applied…..

Secondly, our investors (both internal and external) expected that the work we did was thorough, innovative, ‘leading edge’. Not just based on the latest shiny seismic processing algorithms….

Finding Petroleum has become focused on webinars and I’m in the process of setting up our program for next year.
I'm very much focused on the components of what I'd call "Thorough Exploration".....

Broadly what we do covers two categories, either regional exploration (Caribbean, SubSaharan Africa – a couple of exploration ‘hotspots’ in the hands of Exxon, Hess, Shell, Total) or technology/methodology.

On the latter, we’re putting together a series going from Source Rocks (Jan 27th), Petroleum Systems (done on Oct 7th), Attributes/AVO from 3D Seismic (February 17th), E-M (March 3rd), hopefully eFTG later in March.

Our webinars are nearly always on Fridays at 1pm, for an hour via Zoom.

Amplitude vs Offset talk by Patrick Connolly

Talk Description.
Amplitude analysis can add an extra dimension to seismic interpretation in reducing uncertainty on

prospect risk and reservoir characterisation. AVO (amplitude variation with offset) allows the

construction of images that can highlight different aspects of the subsurface. Subsequent amplitude

inversion can directly estimate reservoir properties. As data quality and algorithms improve and

with better cross-discipline integration, quantitative interpretation has an increasing role to play.

Amplitude interpretation is inherently uncertain, and results are always ambiguous to some extent.

To deal with the integration of disparate data with varying levels of uncertainty, Bayesian methods

are increasingly employed within the workflow. Processes to directly estimate facies probabilities

from seismic data now commonly make use of a Bayesian framework. This allows geological

understanding of the reservoir, no matter how uncertain, to be integrated as prior information.

Seismic interpretation, however, remains a contact sport; there are too many unknowns always to

allow optimum parameters to be calculated and results will be ambiguous to some extent.

Interpreters must use their judgement throughout the process. This requires examination of the

data in the form of an image that can provide geological context. The seismic image remains


Patrick Connolly is former senior advisor, geophysical analysis, with BP. He invented elastic impedance, the seismic net pay method, and inversion by matching to pseudo wells, and is co-inventor of extended elastic impedance.

Q&A followed by Close no later than 14:15

David Bamford is well known around the oil & gas industry both as an explorer and a geophysicist. He holds a Physics degree from the University of Bristol and a Ph.D in Geological Sciences from the University of Birmingham.

Since 2004, he has been a non-executive director at Tullow Oil plc, being recruited for this position especially for his exploration knowledge. He serves on the Nominations and Remuneration Committees, and was chairman of the latter, and Senior Independent Director, for 3 years prior to his retire from the board at the end of April 2014.

He joined the board of Premier Oil in May 2014.

He retired from BP plc in 2003, his last four positions being Chief Geophysicist (1990-1995), Business Unit Leader (General Manager) for first West Africa and then Norway (1995-1999), and finally Head of Exploration until 2003.

He has served on the boards of Paras Ltd, a small exploration and IS/IT consulting company in which he held 22% equity, until its sale to RPS Energy in 2008 and Welltec a/s, a Danish well engineering company, as the nominee of the private equity investor Riverside.
From 2012 to 201 he was on the board of ASX-quoted Australia Oriental Energy as a non-executive director.

He was a founder of Richmond Energy Partners, a small oil & gas research house, and several media companies that focus on the oil & gas sector, and has served as an advisor to Alliance Bernstein, Opus Executive, the Parkmead Group plc, and Kimmeridge Energy LLP. Since retiring from BP, he has undertaken asset and company valuation projects for investment banks, hedge funds and small oil companies.

Future Energy Partners Ltd
Future Energy Partners (FEP) is a unique oil and gas advisory service which prides itself on technical excellence in selected fields and supplementing business management and leadership; in the face of uncertainty.

We offer truthful, professional opinion and advice; no playback of what you already know, and no spin.

FEP was founded by 4 senior industry practitioners who consider the challenges faced by today's oil and gas environment are going to require herculean acts of leadership and technical skill in a transforming, transitioning, industry, in order to maintain an energy supply that is sustainable and even recognisable compared to recent history.

Similarly nations developing an oil and gas industry face related challenges as they seek to maximise the benefits of this new wealth-creating opportunity - in a responsible manner.

Global reach

FEP actively participates in the facilitation and conduct of seminars and webinars worldwide, for example in conjunction with its associate partner Finding Petroleum.

Our presence reaches parts of the globe, such as: the UK, the USA, Sub-Saharan Africa, with partners wherever we work.
