We have long experience in developing software for reservoir 3D modeling and mapping through several years of working with, and developing , the software products IRAP RMS and Petrel.

Combined with our strong domain knowledge in seismic interpretation, reservoir modeling and reservoir engineering, we are strongly positioned to deliver high quality and cost efficient products for our customers.

What do we develop?

  • development of standalone software applications
  • development of plug-in applications
  • integrating legacy software into the Petrel framework
  • development services as a consultancy (programming, advisory role, joint development, etc)
