Analyzing fractures from seismic for improved drilling success ///

The Pinedale Anticline in Wyoming, USA, has become an area of significant interest since the recent success of several gas wells completed in its tight sandstone reservoirs. A new technique, AVAZ, that detects open natural fractures in the reservoir uses azimuthal variations in the amplitudes of seismic data, at long shot/receiver offsets, to identify fractures. A modification of this technique has been used on a portion of Veritas’ multi-client 3D survey over the Pinedale anticline to identify the presence of these fractures in the interwell region.
