CROSSWELL IMAGING OPERATIONS

Crosswell Imaging Technology: A Proven Tool to Enhance Optimization
Crosswell Imaging technology has been successfully used for more than 10 years in such applications as locating Bypassed Oil, monitoring EOR activities, and directing both SAGD and Unconventional Gas activities. 

This technology is able to generate views up to 100x the resolution of surface seismic and provide an extended vertical perspective in addition to the conventional aerial views generated through surface operations.  Today, Crosswell Imaging is proving to be an effective tool for providing operators the detailed information they need to better understand both the structural characteristics of the reservoir and the details of the interwell area.

A true Revolution in Resolution™, Crosswell Imaging technology provides a high-resolution view of such key reservoir properties as porosity, permeability, and saturation conditions. 

How It Works

Crosswell Imaging operations normally access two or more wells simultaneously.  A downhole seismic transmitter, or source, is lowered into one well, and a receiver array is lowered into one or more adjacent wells.  Very high bandwidth sound waves (typically 100 to 2000 Hz) are transmitted from the source to the receivers.  Through this process, seismic data are collected between the wells directly across the reservoir or other zones of interest.  This data can be generated for up to a kilometer between wells, providing detailed information of the reservoir over a broad expanse of space.
