6D Interpolation of Seismic Data – Rationale, Practice and FAQs

Mark Ng and Dan Negut

For many reasons, such as acquisition limitations, economic constraints, and merging data of various shooting parameters from different vintages, seismic data needs to be regularized, upsampled, reconstructed and interpolated. Furthermore, a common deliverable of interpolation is regularized prestack data which will improve many state-ofthe- art inversion processes and migration imaging.

A Well-Guided Processing Approach

Regan Kennedy, Josh Curtis, Greg Staples and Kristof De Meersman

In any processing flow countless parameter choices are made, including which processes to apply, what order to apply them in, and how to parametrize them. In seismic processing, many different but sound choices can all produce similar images. These similar images may not be geologically equivalent when examining all products…

Geologically Constrained Anisotropic Depth Imaging in the Central Burma Basin, Onshore Myanmar

Rob Vestrum, Christophe Gonguet and Tim MacArthur

Understanding the local structural styles and sedimentary sequence is key to constraining depth-migration velocity models in structured onshore seismic data. Judicious application of geologic constraints in the model building resulted in compelling imaging improvements on 2D seismic in this structurally complex area.

Seismic Reprocessing for Improved Imaging in the Permian Basin

Rob Holt

Seismic data enables us to visualize the subsurface in three dimensions with sufficient vertical resolution to identify all but the thinnest of our oil and gas reservoirs. Using seismic data, interpreters map changes in reservoir depth, thickness and character between well locations, and identify the larger faults that create potential…

Sonic Velocities and Depth Conversion

Robert Pickering

The current method(s) of converting seismic time data to depth are methods created to work-around the lack of access to an adequate volume of velocity data. Access to sonic velocities provides the opportunity to move all variables of the depth equation into the depth domain where mathematically and geologically correct…

CSEG Distinguished Lecture Tour 2016/2017

Laurie Weston Bellman

It dawned on me about two months after accepting this role as the 12th CSEG Distinguished Lecturer that, aside from being an honour to be chosen, it might be a significant commitment. Dr. Don Lawton (2016/2017 CDL Committee Chair and 2013 CSEG Distinguished Lecturer) had sent out 30-plus emails, copying…

New technologies for permanent reservoir monitoring - the CaMI Field Research Station

Don Lawton

The Containment and Monitoring Institute (CaMI) of CMC Research Institutes, Inc. and the University of Calgary have constructed a Field Research Station (FRS) near Brooks, Alberta, for research into monitoring technologies for containment and conformance of fluids injected into the subsurface.  The FRS is a platform for development and performance…

The (Geo)Science of Safety: How Geoscientists are Making Potash Mines Safer

Craig Funk

Potash, a mineral used primarily in fertilizers, has been mined in the province of Saskatchewan, Canada for some fifty years. When geological disturbances or anomalies are encountered during mining, mining crews exercise extra vigilance because the integrity of the roof can become compromised introducing the potential for exposure to falling rock.…

Geoscientific Data Adds Value in Unconventional Reservoirs: Statistically Quantified

Fernando Alvarado Blohm

A dataset of 25 metrics collected from the annual investment reports of 9 public operators in the Bakken Formation is used for statistical analysis of the value of geoscientific data. According to results of this analysis, for each million dollars invested in the geosciences, P90 reserves increase, on average, by…

Creating Economic Independence in Southeast Asia

Kathleen Dorey

Considering the challenging times in the Canadian oil and gas industry for the geophysical profession, this article will demonstrate the successful and value-added application of geophysics by a Canadian oil and gas company in Laos, Southeast Asia. The value added by geophysics is quantified by calculation of the oil and…

Assessing Risk to the Ermelo Ring Road from Historical Coal Undermining Using Helicopter TDEM and Ground Geophysics

Jean M. Legault, Karl C.H. Kwan, Zihao Han, Geoffrey Plastow, Robert Wilson, Pierre Roux, C.J. Stoffel Fourie

The South African National Roads Agency Ltd (SANRAL) appointed AECOM SA (PTY) Ltd (AECOM) in August 2014 to investigate the viability of constructing a proposed ring road around the town of Ermelo, in the Mpumalanga Province, South Africa. Coal mines have been operational in Ermelo since the mid-1800s, the majority…

Hydraulic Fracturing Data Integration – What Should I Be Asking My Engineer and What Are They Trying to Tell Me?

Dr. Jennifer L. Miskimins

Communication between technical disciplines in the oil and gas industry is always a challenge. Different definitions, varied nomenclature, diverse cultures and backgrounds all make for challenges when working in the multidisciplinary world of petroleum extraction. This paper is an abridged version of the November 2016 Keynote Luncheon Presentation entitled “Integrating…

Improving Seismic Data Quality by Reprocessing and Redesign of a 3D Survey in an Area of Chaotically-scattered Source-generated Noise

Norman Cooper, Yajaira Herrera-Cooper, Eduardo Trinchero, Luis Vernengo, Raúl Stolarza

The purpose of this paper is to propose a two-fold solution to a complex noise problem in the Gulf of San Jorge Basin in Argentina. Irregularly shaped intrusive bodies scattered at shallow depths over large areas above the reservoir generate a severe signalto- noise problem that masks deeper reflection signals…

Introduction to June Focus: Western Canadian Mineral Exploration Geophysics

Jean M. Legault and Oliver Kuhn

Western Canada is well known for its oil and gas sector, but the minerals sector is also an important part of the resource extraction economy. For CSEG readers not familiar with the minerals sector, a closer look will reveal many parallels with the oil and gas world: dramatic up and…

How Geoscientists are Making Potash Mines Safer

Craig Funk, Janelle Appleyard, Jennifer Braun, Jodi Derkach

Within the vicinity of Saskatoon, Saskatchewan, potash is conventionally mined by three operating companies at five different mines. Continuous boring machines (borers) cut the potash out of the seams at about one kilometer depth. The stratigraphy of the roof above the mined-out rooms (salt-beam) in the Saskatoon area mines consists of…

Geophysics on Fission Uranium’s Patterson Lake South Uranium Deposit

David Bingham

The Triple R deposit on Fission Uranium Corporation’s Patterson Lake South (PLS) property is located in Canada’s Athabasca Basin, home to the world’s richest uranium mines. The deposit is accessible by all-weather Highway 955 which continues north to the UEX-AREVA Shea Creek deposit and former AREVA Cluff Lake uranium mine.…
