Norsar

NORSAR (NORwegian Seismic ARray) is an internationally recognized, independent, not-for-profit, research foundation within the field of geo-science providing advanced, innovative products and solutions to customers in the public and private sectors. NORSAR has its headquarters at Kjeller, North- East of Oslo, Norway.

NORSAR Innovation AS, a wholly owned subsidiary of the research foundation NORSAR, specializes in seismic modelling software and services for the E&P industry.

NORSAR offers a unique ray tracing solution that has been used by leading E&P companies world-wide for more than 20 years.

The core applications of the NORSAR Software Suite include illumination analysis, survey planning, Kirchhoff modelling, 4D time lapse studies, and reservoir analysis.

SEISMIC MODELLING

Seismic modelling methods developed by NORSAR provide value-added services to oil companies, seismic contractors and consultant companies. A software product oriented R&D philosophy ensures short time to market for the results from NORSAR petroleum research activities. Software for seismic modelling and imaging, known under brand names as NORSAR-2D/3D, VelRock and SeisRoX, is made commercial, marketed and sold worldwide by NORSAR’s wholly owned subsidiary NORSAR Innovation AS.

APPLICATIONS

NORSAR 2D/3D ray-tracing

  • Simulation of all kinds of seismic surveys in all kinds of sub-surface models (including VTI/TTI anisotropy)
  • Generation of illumination maps on target level or in shot/receiver domain
  • Studies on expected target fold, simulated migration amplitude, aperture, travel time, angle and offset relationships, and many more
  • Flower plots and interactive illumination ray studies
  • Synthetic seismograms
  • PSDM travel time tables
  • Target based
  • Simulation of shot records and illumination maps
  • Survey planning, interpretation support

SeisRoX local imaging

  • State-of-the-art rock physics modelling technology
  • Fast and flexible 2D/3D PSDM simulation for complex targets and overburden
  • Easy use, based on workflows
  • Consistent with survey, wavelet, overburden and reservoir properties
  • Output of illumination and resolution characteristics (both vertical and lateral resolution)
  • No 1D assumptions and limitations
  • No smoothness requirement as for ray tracing
  • Reservoir based
  • Simulation of optimum PSDM processing result
  • Feasibility and sensitivity studies

VelRock

  • The link between rock properties and seismics
  • Assessment of 4D signature of a reservoir when considering time-lapse seismic surveys.
  • Fully integrated with the NORSAR-2D and NORSAR-3D software packages, but can also be used as a standalone application
  • Assessment of 4D signature of a reservoir when considering time-lapse seismic surveys.
