Misconceptions about Brittleness, and the Talk about Fracture Toughness  
By Satinder Chopra, Ritesh Sharma / August 2017

During the last decade, as the shale resource characterization has come to the fore, the term “brittleness” has become a buzzword.

Futuristic Efforts to Characterize Shallow Anomalies  
By Satinder Chopra, Ritesh Sharma, Graziella Kirtland Grech, Bent Erlend Kjolhamar / July 2017

In this article, we discuss other efforts directed at performing an integrated assessment for the prospects in the Barents Sea, and lowering exploration risk in the future.

Quantifying Shallow Seismic Anomalies  
By Satinder Chopra, Ritesh Sharma / June 2017

Determination of petrophysical properties such as water saturation, effective porosity and permeability, can be carried out using extended elastic impedance approach.

Characterizing Shallow Seismic Anomalies  
By Satinder Chopra, Ritesh Sharma, Graziella Kirtland Grech, Bent Erlend Kjolhamar / May 2017

Many areas of the western Barents Sea host shallow as well as deep-seated hydrocarbon accumulations from which fluids are migrating to the sea floor. Evidence of past episodes of gas migration can be seen in the form of pockmarks on the sea floor as well as vertical pipes or chimneys on seismic sections.

Interpreting Seismic Amplitude Volume Technique Attributes  
By Luis Vernengo, Eduardo Trinchero, Maximiliano Garcia Torrejon, Ignacio Rovira / April 2017

The main challenge for a seismic interpreter is to extract the maximum amount of information from seismic data and integrate that with other relevant data so an accurate reservoir model of the subsurface prospect can be conceived.

What Causes those Annoying Stair Step Artifacts on Coherence Volumes?  
By Kurt Marfurt, Tengfei Lin / March 2017

Since its original introduction 20 years ago, coherence remains, along with bright spots, to be one of the most popular seismic attributes used by interpreters.

Enhancing Seismic Discontinuity Attributes with Creative Workflows  
By Satinder Chopra, Kurt Marfurt / February 2017

Seismic discontinuity attributes such as coherence and curvature are routinely applied to 3-D seismic data volumes to delineate faults or fractures, channel and reef edges, and other geological features.

Deciphering Seismic Amplitude Language  
By Luis Vernengo, Eduardo Trinchero, Satinder Chopra / January 2017

Interpretation of seismic amplitude anomalies could be a direct solution to finding hydrocarbons, or defining lithology, but is usually a tricky problem.

Benefits from Pattern Recognition and Visualization  
By Tao Zhao, Kurt Marfurt / December 2016

Recent developments in pattern recognition-based seismic facies classification (clustering) provide a means to analyze multiple seismic attributes in a single volume.

Enhancing the Quality of Seismic Impedance Data  
By Satinder Chopra, Ritesh Sharma, Rebecca Daniels, Brian Schulte, Jim Pullishy, Tammy Chow / November 2016

Raw seismic data are almost always found to be contaminated with coherent or incoherent noise. Concerted efforts are directed at elimination of such noise during processing of the seismic data, so that its interpretation can be carried out accurately.
