First developed in 1996 for the Campos Basin, Petrobras S.A.'s $20 million Sistema de Gerenciamento de Obstáculos (SGO) Obstacles Management System has been systematically mapping surface and deep-sea obstacles for more than 10 years. It now has more than 40,000 registered obstacles in the Campos Basin, as well as the Santos, Espirito Santo, and Rio Grande do Norte oil basins, which together total about 160,000 square kilometers.
Using MicroStation, the Geodesy Unit programmed a customized interface to allow users to query the database and generate maps of specified areas. Now when companies install, relocate, or remove pipes and other obstacles in the basins, they use the SGO to send a report of their activities to the Geodesy Unit, which in turn updates, adds, or removes the obstacle from the system.
