New technologies extend standard workflows and improve accuracy of production forecasts

During the SEG annual conference Oct. 26-30, Paradigm authors contributed three articles to the show’s daily news publication.  The first article, distributed to all conference attendees Oct. 27, was by Indy Chakrabarti.  Here’s a summary:

While seismic data acquisition today is done in high definition (HD), analysis of HD data has not traditionally kept pace. This has changed with the latest release from Paradigm, which provides users with a return on their HD seismic acquisition through the analysis of data in HD. Paradigm 14 HD capabilities span workflows across seismic data processing and imaging, velocity modeling and seismic interpretation, including quantitative analysis, and offer advances towards high-definition earth modeling.

Paradigm 14 HD processing and imaging methodologies allow users to visualize small features, such as fractures, thin beds and small faults, that are important in the exploitation of modern reservoirs. Quantitative seismic interpretation (QSI) technologies enable the qualification of amplitude prospects to more accurately identify sweets spots in the reservoir.

With the most recent iteration of the release, the company is moving toward HD earth modeling using the volume-based SKUA-GOCAD modeling suite. HD earth modeling facilitates high-fidelity delineation of the most relevant geological features of the subsurface and improves the accuracy of production forecasts with geologic models that are closer to reality. 

An integrated display of data in the Barnett incorporates seismic data, horizons, geobodies, karsts, wells and microseimic data. Major additions to QSI include synthetic workflows for all interpretation and seismic characterization applications. These are enhanced with improved layouts, new checkshot calibrations and new workflows when working with depth-migrated data. The release also provides support for full seismic inversion workflows on the Windows platform.  Prestack gather preconditioning, stacking and inversion are available in both the SeisEarth 3D Canvas and the new 2D Canvas, to support QSI workflows.

New technologies for modeling unconventional plays have been added to the volume-based Paradigm

SKUA-GOCAD modeling suite. These include microseismic data analysis, stimulation path generation for better characterization of complex hydraulic fracture growth and improved assessment of stimulated rock volumes in low-permeability reservoirs. The new SKUA structural uncertainty modeling module enables geoscientists to assess the impact of fault position and structural uncertainty on in-place hydrocarbon estimates and production forecasts to overcome uncertainties and improve forecasting.

Geologic interpretation in the Paradigm StratEarth well log correlation solution has been enhanced with improved data communication with the Paradigm Epos infrastructure and data management system.

Geologic interpretation also includes support for raster logs and zone track improvements, which can enhance ease of use and streamline workflows.

Automatic and with no configuration required, Paradigm 14 product installation is significantly simpler, especially for single users. Numerous connectivity improvements support convenient co-existence with other G&G platforms.  It is now easy to transfer interpretations between the Paradigm Epos infrastructure and Petrel* software via RESQML, using a dedicated Petrel plug-in.  Similarly, users can transfer data directly from Geolog to the Petrel software, for improved multi-team collaboration on shared projects. 

In other developments in this release, the Stratimagic seismic facies classification system is the first Paradigm application to plug-in to the Paradigm Epic open and integrated platform.

Here is the article published on October 27 in E&P Daily New at SEG 2014.
