Landmark Graphics Corporation
Encyclopedia
Landmark Graphics Corporation was created in Houston in 1982 by John Mouton, Andy Hildebrand, H. Roice Nelson, and Bob Limbaugh, to develop one of the first systems for interpreting 3D data from seismic surveys for the oil and gas industry. At first the company designed and built the 3D software and the workstation
s required to run it. However with the advent of cheap Unix-based workstations from other manufacturers over the next decade, it ported the software to their versions of Unix and dropped the hardware side of the business.
The company went on to develop systems for other disciplines within the industry, as well as its OpenWorks database for managing oil and gas industry data.
In 1995 Landmark acquired GeoGraphix to target the market for smaller-scale systems, and in 1996 was itself acquired by Halliburton
, operating at first as a wholly owned subsidiary. Between 2003 and 2006 it was merged with Halliburton and now functions as Halliburton's software and IT consulting arm.
