CGG GeoSoftware enhances technologies
Recently, updates were issued for multiple products in CGG GeoSoftware’s portfolio. In May, new versions of petrophysical analysis
tool PowerLog and geological modeler EarthModel FT were released less than one month after the velocity modeling and depth
conversion application VelPro was upgraded.
PowerLog 9. 5, the latest in the company’s flagship well log petrophysical analysis software, is designed for multi-user environments. It aims to drive collaboration between petrophysicists, geophysicists, geologists, and reservoir engineers for better reservoir
understanding, the company said, offering an “extremely powerful
well log interpretation environment for collaborating quickly and
efficiently on important drilling and production.” Greater insight
into subsurface rock and fluid properties can improve completion
design, helping operators reduce costs and risks while drilling more
productive wells, the geophysical giant continued.
Using EarthModel FT 9. 5, CGG GeoSoftware said that users can determine reservoir properties such as lithofacies, porosity, and permeability, for more accurate modeling results. It combines surface mapping, integrated structural modeling, reservoir property modeling and
upscaling all in one package, with direct output to most flow simulators.
The new version of EarthModel FT offers sandboxes where users can independently explore alternative interpretation scenarios
and store them separately from the main project, the company said.
Changes can be incorporated collaboratively into the central database in real-time, allowing for information sharing.
Additional enhancements for creating 3D geological grids include
an updated algorithm for improved vertical layering, which the company said minimizes the number of layers needed to make a consistent grid model for use in inversion workflows, driving better model
definition and faster inversion results.
These integrated technologies complement each other and; CGG
said, EarthModel FT users can access velocity data with the results
from VelPro 9. 5, which stores data in the shared wells database.
CGG said that VelPro, the latest addition to its “GeoSoftware family” has the capability of helping interpreters and depth conversion
experts build better, more accurate models faster. The velocity modeling and depth conversion technologies allows for the integration of
seismic and well velocity information, horizons, faults, and well tops
into robust and data-driven velocity models.
VelPro models complement the workflows of geophysical interpretation software applications, and are utilized in domain conversions to enable the creation of accurate depth representations of the
subsurface. Users can also better understand and mitigate drilling
risk using the VelPro Pore Pressure Prediction workflow, which employs either the Eaton or Eaton-Bowers method to compute entire
volumes of pore pressure from velocity volumes. VelPro 9. 5 licensing integrates with the full GeoSoftware portfolio.
OGA issues further data tenders
The Oil and Gas Authority (OGA) released a second Invitation to Tender (ITT) for the 2016-2017 UK government-funded seismic program.
This tender is for reprocessing legacy seismic data in seven different lots from seven areas around the UK Continental Shelf, including
the Anglo-Paris Basin; South West Approaches; Bristol Channel and
Northern Approaches; Cardigan Bay; Morecambe Bay and Irish Sea;
East Shetland Platform (including Fair Isle); and the Minches (
including Firth of Clyde). Successful bidders will be required to provide
reprocessed legacy seismic data and the rights for the OGA to publish
the data products. This tender follows a previous ITT issued for acquisition and processing of new regional 2D seismic data in southwest
Britain and the East Shetland Platform.
This year’s program follows the delivery of around 40,000 km new
and legacy seismic data in the Rockall Trough and Mid-North Sea
High areas in 2015. The results of this project were published under
the Open Government Licence, OGA said.
Additionally, in line with the recently issued OGA Corporate Plan,
three separate ITTs are open for regional and field support engineering services, subsurface studies and reservoir evaluation services and geoscience project services. These contracts will replace
the current Oil & Gas Maximising Recovery Programme contracts
and will be three years in duration.
Paradigm opens new center
Paradigm has opened a Seismic Center of Excellence in Mumbai,
India. The center, staffed by domain experts, will be dedicated to
dealing with the challenges associated with processing, imaging, interpreting, and modeling of multi-line 2D seismic surveys.
The Seismic Center of Excellence is part of a Geoscience Services business offered by Paradigm for global oil and gas exploration and development projects. The company says it includes full
azimuth seismic imaging and characterization, diffraction imaging,
seismic inversion, velocity modeling, structural modeling, facies
modeling, fracture modeling, pore pressure prediction, model uncertainty, well log management and others. •
