As you look for oil, keep an eye out for Landmark Graphics. The company develops software used by high-tech wildcatters to find oil, drill for it, and analyze economic return. Databases built with Landmark software store information used by seismic analysis programs to simulate reservoirs and other geological structures. Well planning and drilling applications calculate how to get the oil, while reservoir management software track the amount left. Throughout the process, Landmark's production and economic applications manage risk and measure returns. Customers include BP, Chevron, and Statoil. Founded in 1982, Landmark Graphics was acquired by Halliburton in 1996.
