An interview with Henry Posamentier

INTERVIEW COORDINATED BY SATINDER CHOPRA   “I would encourage those who have an interest in geoscience to embrace an interdisciplinary approach.” Henry Posamentier is renowned for his pioneering work in developing the contemporary approach to sequence stratigraphy, integrating sedimentology, stratigraphy, and depositional systems analysis, primarily in the context of oil and gas exploration. With a career spanning over 50 years at prominent companies such as Exxon, ARCO, Veritas, Anadarko, and Chevron, Henry now serves as a global geological and geophysical consultant to companies engaged in petroleum exploration and development. His expertise covers nearly all significant onshore and offshore basins worldwide, [...]

Temporary Seismic Stations Boost Tomography Capability to look into the Earth. Case Studies in the Northwestern Alps, Italy

STEFANO SOLARINO ISTITUTO NAZIONALE DI GEOFISICA E VULCANOLOGIA, INGV, ITALY, STEFANO.SOLARINO@INGV.IT Abstract Seismic tomography serves as a potent means to investigate the Earth's internal structure. This method closely resembles the one used in medicine and relies on variations (in path, amplitude or velocity) that seismic rays experience when passing through an anomalous body, such as a rock with higher density or an area subjected to high temperature. In the case of seismic tomography, earthquakes act as emitters while seismic stations function as receivers. Unlike in medicine, where a specialized machine ensures a uniform distribution of emitters and receivers, seismic rays [...]

From Seismic to Permeability Characterization: A Combined Rock Physics, BVW Modelling and Seismic Inversion Workflow

DRAGA TALINGA PH.D., SENIOR GEOPHYSICIST, CENOVUS ENERGY, DRAGA.TALINGA@CENOVUS.COM STEVE CUDDY PH.D., SENIOR PETROPHYSICIST, PETRO-INNOVATIONS, STEVE.CUDDY@BTINTERNET.COM Summary Field development of fluvio-marine reservoirs is challenging because the sand distribution in these systems is complex and difficult to predict. The rivers interacting with the marine systems create diverse depositional settings, from river channels and tidal flats to deltas and floodplains. Within these settings, many sedimentary structures are formed, and within these structures, the size, shape and sorting of the grains – all with influence on permeability - are highly variable. The uncertainty in understanding how reservoir properties vary in these complex architectures creates [...]

An interview with Scott Leaney

INTERVIEW COORDINATED BY SATINDER CHOPRA   “Don’t underestimate the value of knowing something at only a single location if you know it well.”   Scott Leaney is a well-known name in our industry who has had a long and illustrious career with Schlumberger. He specializes in borehole geophysics and bringing out more value from surface seismic data by integrating it with borehole data (sonic, 3C VSP, 3D VSP, microseismic, DAS, etc.). Scott trained at University of British Columbia (UBC) under the tutelage of stalwart professor Tad Ulrych, and got the opportunity to work with gurus like Doug Miller, Mike Schoenberg, [...]

3D Phase Congruency: A Novel Technology for Fault Skeletonization

HAYFA AL-SUHAIMI PRINCE MUHAMMAD UNIVERSITY, HAYFA.ALSUHAIMI@GMAIL.COM SALEH AL-DOSSARY SAUDI ARAMCO, SALEH.DOSSARY.6@ARAMCO.COM Abstract The resolution of seismic imagery greatly impacts a geoscientist’s ability to accurately identify and interpret subsurface features. Here, a novel and automated workflow is proposed to generate high-resolution imagery of subsurface geological features, such as faults, fractures and channels. The workflow consists of two components: 1) noise removal, and 2) geo-body edge detection and enhancement. The technology exploits the Phase Congruency Filtering (PCF) technique to produce a higher-resolution subsurface image. The two-component workflow is applied in three broad steps. Firstly, a median filter is applied to the input seismic [...]
