Schlumberger announced today the introduction of a new moment tensor inversion service that provides enhanced analysis of the dynamics of hydraulic fracture propagation. This service will help customers improve their well completion designs through an increased understanding of natural- and induced-fracture characterization in oil and gas reservoirs.
“When applied in unconventional reservoirs, the moment tensor inversion service provides information about the orientation, volume and proppant placement associated with the hydraulic fracture,” said Joseph Elkhoury, vice president and general manager, Schlumberger Microseismic Services. “This provides a framework for building and interpreting geomechanical models, and enables our customers to improve well completion design for improved production.”
The proprietary processing used in the moment tensor inversion service accounts for anisotropy. As the microseismic monitoring industry moves toward quantitative source inversion, the rigorous incorporation of anisotropy in unconventional reservoir models becomes more important to accurately process and interpret the valuable information contained in the microseismic signals.
The moment tensor inversion service has been field tested on microseismic projects in North America. Analyses of moment tensor inversion processing during field trials in the Permian Basin confirm that the incorporation of anisotropy leads to improved interpretation of microseismic data and more robust geomechanical models.
Schlumberger supplies technology, integrated project management and information solutions to customers working in the oil and gas industry worldwide. Employing approximately 120,000 people representing over 140 nationalities and working in more than 85 countries, Schlumberger provides a range of products and services from exploration through production.
Schlumberger Limited has principal offices in Paris, Houston and The Hague, and reported revenues from continuing operations of $41.73 billion in 2012.
