... characterized by sparse occurrences of intrusive and extrusive igneous rock within the pre-salt and post salt horizons, which causes additional challenges for seismic imaging and reservoir architecture modelling. Driven by the challenges and fueled by an innovation spirit, the Libra Consortium have been...

... and seismic data and (2) inversion of field data acquired over the Faroe-Shetland Escarpment. We will show that this information can also be used to improve the velocity models for seismic depth imaging. Introduction Basalts are extrusive igneous rocks that can be found worldwide. Often the compact basalts...

... is still large (8–10 km). Further-more, core coverage is low, especially in the reservoir sandstone intervals. Igneous rock, predominantly basaltic in composition and likely extrusive in origin, occurs more in the eastern part of the field. Igneous activity has complicated the distribution and connectivity...

... ORIGIN OF VOLCANICS: From analyzing a number of wells that have penetrated volcanic rock in the greater Shushan Basin of the Western Desert it is apparent they are extrusive igneous rocks composed of tuffs, volcanclastics, basalts, and probable multiple flows. They also appear to be Jurassic age...
