Meet our experts at the leading multidisciplinary geoscience and engineering event in Europe, and learn how AspenTech® Subsurface Science & Engineering is helping companies like yours. The show will focus on energy security and independence, a sustainable energy transition, and how we all need to adapt our traditional ways of working and cooperation to address an uncertain future.


Full-Azimuth Differential Seismic Facies Analysis for Predicting Oil-Saturated Fractured Reservoirs

This work presents a novel technology for azimuth-dependent facies analysis (Facies Analysis versus Azimuth – FACIVAZ) to improve the prediction of hydrocarbon-saturated permeable fractures in terrigenous carbonate reservoirs. The analysis is performed in the depth domain along high-resolution, full-azimuth, angle domain common image gathers created by the Aspen EarthStudy 360™ imaging system.


Improved Seismic Images through Full-Azimuth Depth Migration

A seismic survey was conducted in a production oil field in Serbia. It was assumed that significant reserves still exist in the field, as well as additional undiscovered reservoirs. An advanced seismic imaging technology was required to further characterize the existing reservoirs and identify and characterize new ones.


Applying Full-azimuth Depth Processing in the Local Angle Domain for Frequency Absorption versus Azimuth (FAVAz) Analysis to Predict Permeable, Oil-saturated Fractures

Predicting the permeability of fractured reservoirs is valuable for both reservoir assessment and drilling planning. Characterization of such systems requires advanced amplitude analysis, mainly based on seismic imaging results of the recorded wavefield.


CRAM Gathers Enhance 3-D Inversion

Elastic inversion from common reflection angle migration (CRAM) gathers can accurately capture lithology-driven lateral variations in reservoir properties, particularly in a strongly deformed and faulted geologic environment.


Geologically Constrained Velocity Models Improve Field Development

Seismic processing, imaging, characterization and interpretation are preferably executed as a continuous workflow to maintain seismic data integrity and consistencies. Geophysicists must construct a workflow from hundreds of applications and algorithms, and thousands of parameters, to achieve desired project outcomes. Almost all these applications and algorithms are based on assumptions about the underlying geological model complexity and subsurface conditions.
