Looking back over the years, I can remember the first mainframe system I ever used back in 1997. At that time, we were on the cutting-edge of technology, which allowed us to create a product drawing by digitalizing and entering x,y coordinates.
Fast-forward 10 years, go to Google Earth and type in an address anywhere in the world. That’s today’s geographic information system technology at its best. Using a GIS you can place any part of your pipeline assets into the real world, even using aerial photos as your background to show where your facilities/pipelines are in relationship to everyday places or locations. This technology is very advanced – especially since most pipelines are buried.
Now when we refer to GIS we talk about data models, station series and facility tables. At the core of the facility database models is the ‘centerline’ section, which is a set of tables that define the pipeline system in terms of its hierarchical structure. The lowest level of the pipeline system hierarchy is the so-called ‘station series’ table, which defines sections of the pipeline with continuous station numbering.
A major challenge faced by risk and threat-assessment analysts in oil, gas and pipeline businesses is typically one of reconciling data from multiple sources (usually multiple database types) for use in their analyses. A GIS allows a company to get all of its facility data into one database and minimize multiple databases.
We refer to our pipeline and facilities as assets within the data model. With the data model, facility tables, station series and code listings, you are on your way to building a GIS. The technology has come a long way in such a short time.
GIS touches everyone in everyday life. Today’s GIS is data-driven, and it allows anyone to find places and assets that can or can’t be seen.

Information source
If you’d like to learn more about geospatial technology as it relates to oil and gas, the Geospatial Information and Technology Association (GITA) hosts a GIS for Oil & Gas Conference and Exhibition every year in Houston, Texas. This year’s event will take place September 24-26 at the JW Marriott. The conference is the largest event of its kind, and it continues to grow every year, featuring paper presentations, half-day seminars, a large exhibit floor and panels all focused on the latest issues in geospatial oil, gas and pipeline.
The theme for the 2007 GIS for Oil & Gas Conference, Houston, We Have a Geospatial Solution, signifies the importance of learning from the mistakes and triumphs of industry peers to create better, more efficient projects. The program will focus on the five topics below. Abstract submissions are being accepted now at www.gita.org/oilgas.
Public awareness
It’s important for every company to know who its stakeholders are, where those people are in reference to the company’s facilities and what types of facilities are located within the company corridor – as well as the land usage. GIS is an excellent tool for managing these spatial challenges effectively.
Land and environmental data integration and management
Companies are using corporate geospatial systems to integrate and display easement, lease, fee ownership and municipal district data, as well as land use type, environmentally sensitive areas, archeological data and other socio-economic data. Areas of interest include the use of mobile solutions to collect and display data, the costs and benefits of such integration, and any other impacts from a management, regulator or field-user perspective.
Enterprise integration
Enterprise integration covers a wide range of issues relating to the linking of geospatial information throughout various enterprise-based systems and/or the use of geospatial technology as a view into other systems and data stores. Systems to be considered with this topic are work/workforce management, enterprise asset management and document management.
Integrity management
This can include mobile solutions (using mobile technology to better collect information supporting integrity management and reduce the cycle time of field data collection); web-based solutions (using web-based technology to distribute integrity management results throughout the organization); technology solutions (how current technology is adding value to pipeline operators’ decision-making processes); risk assessments (using risk assessment technologies/methodologies to make better-informed decisions); and DOT audits (using integrity management and geospatial technology/methodologies to assist and satisfy current DOT audit methods).
Emergency response and planning
Regulatory requirements are dynamic, and understanding exposure to corporate risk relative to homeland security, risk mitigation, planning and first-responders are examples of leveraging geospatial technology to support critical infrastructure integrity, objective methodologies and response.
