China Study: Detecting Fractures  
By Peter Stewart, John Tinnin, James Hallin, Jim Branath / October 2008
This two-part series describes how Sinopec’s local operating company, Southwest Petroleum Branch (SWPB), utilized full-wave seismic data to improve production from a fractured tight-gas reservoir in XinChang Field, Sichuan Province, China. 
Options Exist for Surface Problems  
By Bob Hardage / September 2008
Last month in this space we showed that in areas where poor-quality seismic data are acquired across a high-velocity surface with surface-based geophones, good-quality reflection events are created at deep interfaces below this high-velocity surface layer. 
Getting Under Surface Challenges  
By Bob Hardage / August 2008
In general, the quality of conventional P-wave seismic data is poor when data are acquired across areas where high-velocity rocks (primarily carbonates and basalts) form the exposed, first-layer of the Earth.
Is the Future of Seismic Passive?  
By Bob Hardage / July 2008
Passive-seismic technology encompasses any procedure by which seismic data are recorded without the use of an active seismic source.
Questions? VSP May Have Answers  
By Bob Hardage / June 2008
Vertical seismic profiling (VSP) began to be popular among non-Soviet scientists in the late 1970s, about the time that my previous employer, Phillips Petroleum Company, and our partners were trying to determine development strategies for newly discovered fields in the Greater Ekofisk area of the Norwegian North Sea.
When Thin is In, Enhancement Helps  
By Satinder Chopra, John Castagna, Yong Xu / May 2008
Expanding the frequency bandwidth of surface seismic data is an unending quest for geophysicists, because increased seismic resolution is essential for extracting stratigraphic detail from seismic images.
Going Super-Deep With P-P, P-SV Data

Hello, This Is Your Geophone Calling  
/ February 2007

“Cell” phones are in every nook and cranny of the earth and are used by people of all ages, nationalities and professions. This same cellular wireless technology has now entered the onshore seismic data-acquisition world.
