Gas-Insulated Substations - GIS

sf6 gas is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the insulating gas will not condense into a liquid at the lowest temperatures the equipment experiences. insulating gas has two to three times the insulating ability of air at the same pressure. gaz sf6 is about 100 times better than air for interrupting arcs.

Benefits of Petroleum and Pipeline GIS

Oil and Gas Site SelectionLand Management DataRouting PipelinesGIS is a valuable tool for oil and gas site selection because it gives decision-makers a way to visually evaluate topography, geology, and analyze surface drilling constraints. With GIS mapping, companies and field operators can also overlay high-resolution imagery on site maps to assist with project selections and surveys. Once a site is selected, GIS is an invaluable method for visualizing the well planning process. Because most oil and gas are deep below the earth’s surface, these natural resources require drilling wells for extraction. States and communities pass laws setting safe extraction guidelines. For example, state law in Colorado allows multiple wells on a section of land while protecting the landowner’s right to safely use the land for other purposes. Through intelligent mapping and spatial analysis, companies can view large quantities of geographic data to ensure they comply with laws and regulations in choosing the ideal extraction site.
