Orthorhombic imagingOrthorhombic imaging consists of a set of tools that allow azimuthal anisotropy to be incorporated into velocity model building and pre-stack depth migration. In areas of complex geology, especially where fractures are present, commonly used Tilted Transverse Isotropy (TTI) may not be sufficient for describing moveout variations with azimuth. Orthorhombic anisotropy (ORT) provides a more comprehensive model and orthorhombic migration is able to flatten migration gathers across different azimuth sectors.

The top figure shows the comparison of migration stack images between TTI and ORT. The ORT imaging provides clear uplift in image quality. The bottom figures show the comparison of migration gathers produced by TTI and ORT. ORT is able to resolve the conflicting residual moveout and flatten events across different azimuthal sectors.

The orthorhombic model for azimuthal anisotropy includes nine anisotropic parameters:

� Vo

� Del1 and eps1 in the vertical and horizontal (Vfast) plane

� Del2 and eps2 in the vertical and horizontal (Vslow) plane

� Del3 in the horizontal (Vfast Vslow) plane

� Alpha (a), which represents the azimuthal rotation of Vfast

� Theta, phi (q, f), which represent the normal vector of the symmetry axis

Digital well logsOver seven million well logs in over thirty countries make up TGS’ collection of digital well log data from the most popular hydrocarbon plays around the globe. Depending on customer project needs, the digital formats available for each well log range from depth-calibrated smartRASTER® image files to completely digitized LAS and LAS Plus curve suites. Each format can be conveniently accessed online, through the online well data portal LOG-LINE Plus!® LAS Plus format upgrades standard LAS to a full curve suite. Raw data is correlated and edited providing the best open-hole curves. LAS Plus also provides uniformed curve mnemonics and units. Curves are also merged using the best data. LAS Plus data is ready for cross section, formation evaluation and petrophysical analysis.

Directional surveysTGS set a new standard of quality for ‘user-ready’ directional survey data and well path control. TGS’ Directional Survey Plus (DS+) data are thoroughly researched, re-processed and standardized to create the most accurate spatial representation of the well path, from surface to total depth.

Well performance dataTGS offers a cost effective way to quickly identify and evaluate new prospects across the country with unlimited access to TGS’ domestic U.S. Smart Rasters and Well Performance Data. TGS provides access to nationwide Oil and Gas Well production coverage. Well Performance Datasets include: nationwide Well Headers, detailed monthly production volumes for all wells and leases, a unique set of Oil and Gas statistical well cumulative values and Lease-to-Well Allocated volumes for all lease reported states.

Interpretation productsTGS’ multi-client interpretation products provide regional frameworks for customer prospects. Ranging from complete hydrocarbon prospectivity reports to velocity volumes, the TGS library has products worldwide to supplement data resources. In addition, TGS is available for consulting work in geology, geophysics and petrophysics on customers’ in-house projects.

Digital mud logsTGS has an extensive library of digital mud log curves and raster images for wells across North America. Each log is evaluated to identify the best complete digitizing suite. Mud log gas curves are available as digital LAS files and include raster images (in color when available). ROP, total and individual gas curves are captured as standard; digitized lithology and cuttings remarks are optional.

Data / application integration solutionTGS’ Volant Solutions provides a data/application integration offering that includes the ENVOY integration platform, the EnerConnect user interface and various adapters. With the ability to facilitate application interoperability, the days of data duplication and weak data governance will be eliminated. The ENVOY integration platform is completely configurable and can meet the specialized needs of E&P companies.
