Geological interpretation software using Petra®

Advance your E&P workflows to find more oil and gas.

Petra from IHS Markit is a cost-effective software solution for managing, manipulating and visualizing integrated geological, geophysical and engineering data. Geologists, engineers, technicians and analysts use Petra for exploration, exploitation, infill drilling, reserves analysis, unconventional plays, production analysis and more. With Petra, you can quickly visualize results using mapping, cross-sections, seismic interpretations, log plots, cross-plots, production and reservoir analysis, and 3D visualization. To maximize your subscription, IHS Markit offers technical support as well as Petra training courses at select locations and on site, by request.

Key features of the Mapping Module include:

  • Integrate surface land picture into your subsurface interpretations
  • Post digital/raster log curves and production data to well location
  • Create and customize contour and bubble maps
  • Display core and competed zones and top producer spatial distribution

Petra Module enables you to create customizable cross-section displays to optimize well location selection. Choose one of four cross sections that best fit your workflow:

  • Single well – Display one well for analysis and printing
  • Well-to-well – Connect selected wells in a line
  • Line and wells – Display a projection line that features hand-picked wells
  • Line and corridor – Display a projection line that features selected wells from a rectangular corridor around the line

Discover our other features of the module.

Ranked high in the upper right quadrant of the Welling Report for easy-to-use geological interpretation software, Petra enables you to:

  • Expedite drilling decisions with shorter cycle times
  • Integrate large IHS Markit well, production and log datasets
  • Quickly define reservoirs and prospects
  • Focus on analysis rather than map-making
  • Analyze mergers, acquisitions and divestitures
  • Access enhanced data management with Petra Sidekick to load data into one project while working in another

What are the system requirements for Petra?

No special video cards are required. Petra is compatible with a broad range of high performance video cards and multiple monitor installations. Discover the minimum requirements.

Customer testimonials

“Petra offers such functionality (as store and access data and share in a network environment), coupled with easy data loading routines. The wide range of functionalities, including the incorporation of depth-calibrated raster logs and digitizing capability, is an additional plus.”

– A small, international independent oil and gas producer in Turkey uses Petra as a cost and manpower efficient database system to store and access various types of data which is shared in a network environment

“Our clients include many of the largest oil companies in the world and they are always satisfied with the final products obtained directly from Petra (i.e. very little professional drafting is needed in the final reporting phase). All this makes Petra a simple yet versatile software package to use in time/budget-constrained projects where quick yet precise results are needed.”

– A reservoir modeler who uses Petra in regional and site-specific studies

“One of the most wonderful aspects of the Petra product is the support that is behind it…Many times, I’ve gone in and requested changes be made, and sometimes they are made within a couple of weeks…That’s amazing to me – to be a single user and to have an impact."

– An engineer for an energy consulting firm

“Petra software has everything the geologist would need to build and to do the workflow. The way that it works, the modules, how they fit together, how easily you go from one module to another, from the map to the cross section to the database, how you continue to build out the story within the program—that is very exciting.”

– The president of an upstream development firm
