Computer Resources

WIT maintains state-of-the-art off-site computer facilities in Katy, Texas, and Lakewood, Colorado, USA. The computer facilities are connected to our main offices via broadband business-class cable internet, and are secured with alarm systems, hardware firewall, and a software VPN. The Houston facility is connected to the power grid via a dedicated electrical transformer. In the event of an extended power outage, our transformer is one of the first to be brought back on line by the power company (after Hurricane Ike, we were running after only several hours of downtime. Many service companies were out of commission for weeks). In the event of a short power outage, our Uninterruptible Power Supply (UPS) systems run our servers from battery power.

WIT maintains many high-end Linux servers, each containing a RAID array, which protects project data from the loss of a single disk device. Since 2007, we've had several failures of one RAID disk. In each case, the array was restored on the same day with a new disk without the loss of any project data. We currently boast hundreds of terabytes of RAID storage.

WIT maintains a total of 100 Linux compute "nodes" containing 8 processors, and another 80 nodes containing 4 processors. All systems run the Fedora Linux operating system. We therefore have over 1,000 CPUs across which we can parallelize large jobs. Our most recent 80 machines were leased from Dell Computer. This rack mounted system was delivered and running in less than a month after initial ordering. Our ample electrical power means that we can add hundreds more machines in short order if a large project is awarded.

WIT can read any modern tape media; for very old or rare formats, we outsource data transcription to well-known firms like Ovation Data Services or Tyrrell Data Services.

Clients may engage in live interactive sessions with WIT personnel via Go-to-Meeting. Small deliverable files, i.e., those less than 1 GB in size, can be uploaded to a secure FTP server to enable quick QC by the client.

Depth Imaging Software

WIT is proud to use the WavePak seismic processing system, developed by Dr. Joe Higginbotham, for depth imaging. WavePak was intended to provide a friendly environment for developers and was also intended to be easy to maintain and to port. This was important because good software was being lost when companies moved to new hardware and operating system environments.

Like many other seismic processing systems, WavePak uses "piping" to run multiple sequential seismic operations without the need to write intermediate results to disk. However, rather than using operating system piping, the piping in WavePak is programmed directly into the system. This fact enabled Dr. Higginbotham to very naturally develop a fault-tolerant, load-balanced data parallelism using the Parallel Virtual Machine (PVM) developed by Oak Ridge National Laboratory.

Time Processing Software

  • ProMAX for basic processing
  • SUMMIG from Techco. Prestack or Poststack Kirchhoff time migration
  • Green Mountain Geometry and Refraction Statics
  • Renegade Seismic Studio
  • GLI
  • Flatirons refraction statics from Canonical Geosciences
  • MASTT from Techco (almost always beats ProMAX)
  • Bandwidth extension tool, azimuthal residual velocity analysis (time), and spectral decompositionProMAX plugins from Crestone.
  • We plan to add a .5D Interpolation. tool soon.
  • SCDCN from Techcho. Gives similar results to ProMAX but the spectral whitening works better.
  • VisualVox from Geomodeling. We can use this to produce many poststack attributes and perform interpretation functions.
