SANDIA REPORTS IMPROVED DOWNHOLE SEISMIC RECEIVER
Sandia National Laboratories, Albuquerque, reports a successful field test of a downhole seismic receiver it says offers several improvements over previous models. The Sandia receiver has a broader frequency range and a new type of sensor for better resolution of seismic signals in cross-well imaging. The technique involves placing seismic sources and receivers in separate wells in an oil or gas field. The goal is to help obtain a better image of a field's structure.
