Parex Resources Inc engages in exploration, development, and production of crude oil. The company brings technology utilized in the Western Canada Sedimentary Basin to South American basins with large oil-in-place potential. Majority of the company's properties are focused in Colombia, where it pays a royalty or tax to the government for its operations. Parex depends on a team of geologists and geophysicists, in partnership with technologies such as 3D seismic surveying, to help exploration efforts. Oil production is sold to a small basket of participants in South and North America.
