Science Break: The Math of Mosaics

…It is a common misconception that the artistic depiction of people is forbidden by Islam. Scholars debate this – various hadiths contain such prohibitions, but many of them are specific to this or that sect within Islam. But regardless, within the Islamic world the depiction of people in art, especially…

Bill Goodway

An Interview with Bill Goodway

…Q&A You pioneered the development of the LMR attributes in 1997. After 17+ years of its applications in the seismic world, what do you have to say? My motivation for introducing LMR back in the 90’s has endured I believe due to the insight and improved understanding of extrinsic velocity…

Clare Bond

An Interview with Clare Bond

…Q&A There are a number of possible interpretations to a given seismic image. This is a very true statement. So, the interpreter needs to narrow down on the interpretation possibilities. Do you think the seismic interpreters in our industry are familiar with this, and if yes, are they really following…

Duncan Emsley

An Interview with Duncan Emsley

…Q&A You make an important point in that before beginning interpretation of seismic data, it is important to assess its quality and be aware of the processing flows. Though this seems to be the right thing to do, how much of it is being done in our industry? I would…

Joint Inversion of Multiphysics Data for Petrophysical and Engineering Properties

Aria Abubakar

…A variety of measurements may illuminate the reservoir with varying coverage and resolution such as: electromagnetic (EM); controlled-source EM (CSEM); magnetotelluric (MT), surface-to-borehole EM (STB-EM); crosswell EM; seismic (surface seismic, crosswell seismic, and VSP); gravity (surface and borehole); and production history/well testing data. The interpretation of each measurement on its…

A Comparison of Trenched Distributed Acoustic Sensing (DAS) to Trenched and Surface 3C Geophones – Daly, Manitoba, Canada

Rob Kendall

…In the fall of 2012 we conducted a field test of a trenched fibre optic Distributed Acoustic Sensing (DAS) system to trenched and surface 3C geophones in the Daly area of southwestern Manitoba, Canada. The test was designed to provide a comparison of the acoustic wavefield as measured by the…

3D VSP in an Unconventional Setting: Images, Anisotropy, Q, Multiples and Full Waveform Inversion

A. Campbell, S. Leaney, J. Gulati, O. Podgornova, J. Leslie-Panek, E. Von Lunen

…A comprehensive seismic project including conventional and multi-component surface seismic and borehole seismic was acquired in a producing field in northeast British Columbia, Canada. Delineating productive zones within the fractured shale reservoir was the primary goal of the seismic recorded in the project. The borehole seismic includes a conventional P-wave…

Acquiring Low Frequencies Onshore: Sweep, Sensors, Sampling and Stories

Olivier Winter, Anna Leslie, Forest Lin and Peter Maxwell

…The authors discuss the generation of low frequency onshore seismic exploration. Seismic vibrator sources, geophone and MEMS accelerometer sensor properties are discussed. This is followed by a brief discussion of processing implications outlining the need for some precautions to take in order to preserve the broadband characteristics. Several case studies…

Lithology Discrimination Using Elastic Rock Properties and Simultaneous Seismic Inversion in the Leduc Reservoir, NE Alberta

Elahe P. Ardakani, Tom J. Podivinsky and Douglas R. Schmitt

…AVO attributes (elastic rock properties) crossplotting and simultaneous seismic inversion are used in an integrated approach to discriminate dolostone from limestone lithologies in the carbonate Leduc bitumen reservoir located in northeastern Alberta. The profile sections of density, compressional and shear impedance are generated through the simultaneous seismic inversion procedure. The…

Executive Message

…As my term as Director of Communications comes into full swing, I have newfound respect and admiration for the hard work and dedication of my predecessor, Jason Schweigert. Jason was responsible for implementing the new CSEG logo and design templates across the society and all its subcommittees. He also played…

CAGC Column

…Technology and, more specifically, social media, has changed the way people communicate with each other. Face-to-face contact is slowly declining as each new item in Best Buy, or new app in the Apple store makes it easier to communicate in any way other than speaking to each other. The CAGC…

Science Break: A Fire in the Mind

…There has been a powerful social trend recently towards more open attitudes concerning mental illness. Mental illness is very prevalent, with about 1 in 3 people experiencing symptoms at least once in their lifetime, meaning many of us have grappled with it, and each of us most certainly is close…

Optimizing Hydrocarbon Recovery In Organic-Rich Reservoirs

Cristian H. Malaver

…The search for hydrocarbons in tight reservoirs has become an integral part of the portfolio for oil and gas companies these days. Predicting reservoir quality indicators from tight facies such as organic-rich shales, tight oil carbonates, tight sands, and coal seams is a complex challenge demanding a multi-disciplinary effort. By…

Introduction to May Focus: Land Data Acquisition

R. Malcolm Lansley

…This month’s Focus is related to land data acquisition. In the early days of recording 3D on land the general recording geometry was very similar no matter where in the World the survey was being acquired. Although we recorded data with both explosives and vibroseis and the geometries were slightly…

Optimal restriction modeling

Keith Millis, Case Caulfield and Andrea Crook

…Restrictions to seismic acquisition increasingly limit the positioning of both sources and receivers at theoretically prescribed locations. Designing and subsequently repositioning station locations with respect to those restrictions has become an important and time-conscience aspect of both land and marine seismic programs. Historically, deviations from theoretical locations are prescribed in…
