A New Approach to Stratigraphic Interpretation  
By Satinder Chopra / September 2013

This article introduces a new set of seismic attributes that play an important role in extracting detailed stratigraphic information from seismic data.

Quantitative Curvature Analysis: A Case Study  
By Satinder Chopra / August 2013

Last month in this space we analyzed the relations of fracture patterns and layer curvature in clay models. This month we examine these relations in a central Oklahoma field developed by Pathfinder Exploration, Norman, Okla.

Testing Curvature’s Impact on Fractures  
By Satinder Chopra / July 2013

Fracture zones can be critical to improving or creating sufficient porosity and permeability in hydrocarbon reservoirs – with strain, along with lithology and thickness being the major controls.

Finding the Path Past 'Attribute Footprints'  
By Satinder Chopra / June 2013

Three-D seismic surveys usually are designed in a way that the subsurface features are regularly sampled in different dimensions, comprising the spatial coordinates, offsets and azimuths.

What Is Seismic Interpretation?  
By Satinder Chopra / May 2013

Seismic Interpretation is the extraction of subsurface geologic information from seismic data. On that definition we all are agreed.

It’s Just a Phase (Residue)  
By Satinder Chopra / April 2013

In the March issue of Geophysical Corner, my colleagues Marcilio Matos and AAPG member Kurt Marfurt discussed the concept of phase unwrapping and the computation of phase residues.

Out of Phase Doesn’t Mean Out of Luck  
By Satinder Chopra / March 2013

Interpreters use phase each time they design a wavelet to tie seismic data to a well log synthetic.

Micro MDPs Can Be a BIG Tool in Fault Finding  
By Satinder Chopra / February 2013

Microseismic technology is crucial these days for understanding reservoirs and planning development programs.

Time to Pick? No Need to Fear ‘Seismophobia’  
By Satinder Chopra / January 2013

While seismic processing shops usually are the “professionals” when it comes to velocity analysis, the interpreter may have greater insight into the cause of the poor data quality.

A Solid Step Toward Accurate Interpretations  
By Satinder Chopra / December 2012

This month’s column deals with quantifying facies variation.
