The whole coastal region is an area where the application of ports because of the large scattering width of the tides, the frequent winds and lack of fresh water on the surface is difficult. Nevertheless, it has created across thanks to the fish stock and the occurrence of hydrocarbons, deep-water ports and loading and unloading by buoys.

The basin of the Gulf of San Jorge
The Gulf San Jorge, caused by tectonic subsidence, includes a geological formation that extends to the south of the province of Chubut and Santa Cruz in the north of the province, as well as on the seabed. This geological basin is the result of switching between periods of marine retreat with continental sedimentation and sea rise with meeressedimentation while millions of years, which has generated underground storage of non-renewable fossil hydrocarbons ( oil and gas). The gas production is delivered via pipelines to Gran Buenos Aires, the oil production of this basin is mainly transported by tanker. The production of crude oil of this basin is the oldest in Argentina. As this fuel in 1901 was discovered by accident while drilled a well to supply the then small nest Comodoro Rivadavia with water, the significance of which it occupied, resulted in one short time later, the Argentine state-owned company YPF ( Yacimientos Petroliferos Fiscales ) founded and during the Second world War is created as a political department, the military zone of Comodoro Rivadavia. The main deposits of the basin of the Gulf of San Jorge are in the vicinity of the cities Comodoro Rivadavia, Caleta Olivia, Caleta Córdova, Pico Truncado and Las Heras.
