A study is made of petroleum infrastructure expansion, or petroscape, in three of Venezuela's four heavy oil operations between 1990 and 2005. A change detection method using Landsat and CBERS satellite imagery and a GIS is implemented for gauging estimates in land use and land cover change (LULCC). The objective is to determine which Associations showed the greatest and least reduction in biomass tied to petroscape growth in a time series corresponding to the before, early and full production phases. Results indicate variability in the amount of land use dedicated to petroleum infrastructure among three (of four) operations which consists of partnerships between the state oil industry and multinational oil companies (MNOCs).
