Event description

Description

Please, note that this event will host two speakers, what will not affect the regular timeline of the event.

The first speaker

Ali Karagul completed his Bsc’s degree in Petroleum Engineering from Middle East Technical University, Ankara, in 1986. He joined GSI as a Field Seismologist where he has worked in field crews in the Middle East. In 1989, he joined CGG as processing geophysicist and worked in Asia, Middle East, Europe and North America. He continued as a Geophysical Advisor until moving to TOTAL E&P Aberdeen, the UK in 2014 as Senior Operations Geophysicist. He has presented papers and published on a variety of topics within processing geophysics with an emphasis on implementation of new technologies at EAGE and CSEG conferences in 2004, 2006, 2007 & 2014. He also participated in several software evaluations and convergence programs together with helping to develop training programs.


The abstract

Oil & Gas companies would like to maximise the potential of their assets by leveraging the expertise at different levels. The industry recognizes the large uncertainty in which operates which need to be addressed. In the literature, there are several papers addressing these and some suggesting why we need to change the way we educate our engineers about uncertainty no later than undergraduate level without forgetting the need to change for the ones working in our industry.

If one searches “uncertainty” at www.onepetro.org (an online library of technical literature for the oil and gas exploration and production industry), can get more than 39,000 papers published on the titles of them.

Learning to quantify the uncertainty could be a lifelong process, the education can be done through; conferences, workshops and short courses and talks covering directional biasing, probabilistic modelling and decision analysis.

Seeing and observing the effects of the above subject by himself during his career, he decided to share his experiences with the Geoscience community in the hope to increase the awareness about the topic.


The second speaker

Tony Martin works for PGS in the role of Principal Geophysicist. He has 25 years industry experience working for both contractors and operators, and has worked in various locations around the world. He has been published on more than 25 occasions. He is a member of the EAGE, SEG and an Associate Editor for Geophysics.

The abstract

Velocity model building using a tomographic inversion engine produces one credible realization of an earth model, generating one plausible sub-surface image. The inversion attempts to minimize the difference between the unknown true model and a best guess version; by its nature it is highly non-linear, leading to uncertainty in the traditional single model and image approach. A methodology for reducing uncertainty is to use a significant model population that all equally explain the data by producing flat gathers from a tomographic inversion. This big data approach to imaging can follow a pseudo-random approach, enabling statistically driven error bar analysis on the spatial reliability of the data.
