Sandra Allwork, Team Leader and Technical Sales Advisor, analyzes and interprets seismic attributes in order to observe, extract and map shale heterogeneity, in-situ stress and brittleness in an Eagle Ford project.



Topics Covered
  • Maximizing the value of seismic data in shale resource plays
  • Co-visualization enhances the validation of results
  • Full-azimuth analysis provides the most accurate fracturing orientation information
Shale plays have become one of the most important sources of hydrocarbons. Due to their unique nature, shale plays pose challenges in reservoir exploration and production. Geoscientists have been searching for solutions that can determine and qualify the “sweet spots” where the production and recovery rates are highest in the shale formation. Seismic data carries critical information on rock properties much needed in prospect identification, ranking and well planning. With the application of established and recently developed technologies, many attributes can be generated using seismic data, including post-stack attributes, rock property attributes and anisotropic attributes. The integrated analysis and interpretation of these attributes enable geoscientists to understand the heterogeneity nature of the studied shale formation, and estimate and map the 3D distribution of shale brittleness, stress intensity and its orientation.

In this presentation we incorporate available seismic data and well data, and analyze and interpret varieties of seismic attributes in order to observe, extract and map the shale heterogeneity, in-situ stress and shale brittleness in an Eagle Ford project.
