EAGE Course: Rock Physics for Quantitative Seismic Reservoir Characterization

Thursday, July 5, 2018

Rock Physics for Quantitative Seismic Reservoir Characterization

Course description

This course covers fundamentals of Rock Physics ranging from basic laboratory and theoretical results to practical “recipes” that can be immediately applied in the field. We will present quantitative tools for understanding and predicting the effects of lithology, pore fluid types and saturation, saturation scales, stress, pore pressure and temperature, and fractures on seismic velocity. We will present case studies and strategies for quantitative seismic interpretation and, suggestions for more effectively employing seismic-to-rock properties transforms in reservoir characterization and monitoring, with emphasis on seismic interpretation for lithology and subsurface fluid detection.

Course outline

  • Introduction to Rock Physics, motivation, introductory examples
  • Parameters that influence seismic velocities - Conceptual Overview
  • effects of fluids, stress, pore pressure, temperature, porosity, fractures
  • Bounding methods for robust modeling of seismic velocities
  • Effective media models for elastic properties of rocks
  • Gassmann Fluid substitution – uses, abuses, and pitfalls

Please check this page for updates on course locations and times in your city. Some of these talks will talk place over lunch.

The day-long course is aimed at:

  • Seismic interpreters who want to extract more information from their data.
  • Seismic processors and imagers who want to learn how their efforts impact subtle stratigraphic and fracture plays.
  • Sedimentologists, stratigraphers, and structural geologists who use large 3D seismic volumes to interpret their plays within a regional, basin-wide context.
  • Reservoir engineers whose work is based on detailed 3D reservoir models and whose data are used to calibrate indirect measures of reservoir permeability.
  • Team leaders who wish to identify advances in machine learning technology that promise improved efficiency and accuracy in the integration of large data volumes.

Exploration geoscience inside the mine gate

Standard practices in exploration geoscience can add value in resource definition and inside mining operations. Mineralogical and geometallurgical proxies are available through multi-element geochemical assays. Petrophysical suites can sometimes provide timely substitutes for assays. Drill feedback parameters are directly influenced by the rock and hence contain information on rock mechanical properties. Finally, it must be recognised that even very dense drilling vastly undersamples an orebody, and geophysics is the only avenue for filling in the space between drill holes. Furthermore, the bulk sampling of geophysics can provide rock characterisation that is often already at a scale suitable for mine operations.

Chris Wijns has been the Group Geophysicist since 2008 for First Quantum Minerals Ltd, a global copper miner. Previously, he held a similar role with gold company Resolute Mining. Chris studied geophysics degrees in Canada, and worked in gold exploration in West Africa before moving to Australia in 1999, where he completed a PhD in 2004. He has enjoyed working inside sizeable companies for the opportunity to have constant interaction with geologists, geochemists, and assorted engineers and metallurgists. Chris enjoys the challenge of bringing research results into the mining and exploration industry, as well as finding opportunities for geophysics to add value to mine development and operations.

WA YP Speakers Night & 2018 Mentoring Program Introduction

PESA WA and ASEG WA are joining together to support the Young Professionals of the petroleum industry by organising two initiatives: Speakers Night and a Mentoring Program.

Speakers Night

A “Speakers Night” will be started where young professionals will have the opportunity to present their work to other young professionals in a safe and welcoming environment. The “Speakers Nights,” will allow young professionals to become more confident making presentations to an audience, a skill that is very valuable for most people in our profession.  

Our first speaker is Amy Millar, whose joint work won the Best Oral Presentation in the Energy Section of the AEGC held in Sydney during February 2018. After Amy has made her presentation, Simon Molyneux, an experienced oil and gas professional will be sharing his career path. There will then be a Q&A session and discussion about presentation experiences from another young professional who presented at the AEGC 2018.

If you are interested in presenting or would like to nominate someone to present please email Jordan McGlew (jordan.mcglew@gmail.com).

Refreshments and finger food will be provided.
Please register for catering purposes prior to close of business Monday 9 April 2018

Joint Mentoring Program

PESA WA and ASEG WA are initiating a "Joint Mentoring Program" to create an opportunity for young and junior professionals to increase their capability using the support and guidance from experienced professionals.  An overview of the mentoring program will be presented at the first ASEG – PESA Young Professionals Speakers Night. The mentoring program is FREE for PESA and ASEG members.

Please register your interest before April 30th by sending an email to:   wa-mentoring@pesa.com.au (Ishtar Barranco  &  Simon Molyneux) or  wasecretary@aseg.com.au (Carolina Pimentel)

Application of the passive seismic Horizontal-to-Vertical Spectral Ratio (HVSR) technique for embankment integrity monitoring (and a bit more)

Embankments are common features in mine sites necessary for tailings storage, surface water management or general infrastructure such as dewatering ponds. Differing construction methodologies, from loosely placed waste material to engineered embankments with individually compacted lifts, will achieve varying density, strength and permeability. Conventional construction quality assurance is however not always possible without causing significant interruptions to the construction program. Estimating levees’ bulk shear wave velocities via passive seismic HVSR surveying as a proxy for stiffness is a practical, continuous and non-invasive method that can be carried out with limited construction interruption. Field data acquired over the length of several embankment types demonstrate the very good correlation between estimated shear wave velocities and the levees’ degree of compaction. As a result, alternative construction methodologies can be quantitatively benchmarked against an apparent shear wave velocity spectrum with fully engineered embankments and loose waste dumps as end-members. Collection of repeated measurements over time also discriminates stable embankments from altering ones, and constitutes a cost-effective way to identify possible zones of weakness before hazardous failure.

Regis Neroni graduated in 2006 with a French Master’s degree in Geosciences, Environment and Risks from Strasbourg University. After spending a few years undertaking ground electrical surveys in outback Australia, he consulted to numerous mineral exploration companies with active projects mainly in Australia, SE Asia and Africa, alongside some of the most talented consulting geophysicists in Australia. He then worked as a company geophysicist for Barrick and Rio Tinto where he took part in multi-commodity exploration programs throughout Australasia. He is currently Fortescue Metals Group’s Lead Geophysicist and steers the company’s geophysical endeavours across their Pilbara-based operations and exploration projects in Australia and South America.
