GIS in Oil and Gas

BY SANGEETA DEOGAWANKA


As an industry that fuels progress, development and basic human needs, the oil and gas industry is a vital part of the global economy. It is also the most capital intensive. Revenues are large, as are the costs. It also makes headlines for unforeseen accidents and environmental hazards. The ever changing dynamics of this industry drives sustained efforts for increased efficiencies and risk mitigation. This is where GIS and supporting technologies step in with limitless uses and seamless applications.

The Oil and Gas industry is driven by an estimated 80% data that has a spatial component. This is the only industry that harnesses spatial information at every stage of the life-cycle, beginning with opportunity analysis and exploration, through appraisal and production, right up to the abandonment phase.

So companies are beginning to understand the importance of geospatial to maximize ROI as well as minimize risks. Beginning with the integration of spatial databases within existing systems, the oil and gas sector has also begun looking at software companies to come up with industry-specific software, tools and models to maximize value from their investments.

For the geospatially driven this is an industry to look at. Assets, offices, sites, workers as well as operations are geographically dispersed. So large and complex data is utilized to explore and manage the spatially distributed assets and operations. Dedicated maps and models are proving to be the most effective way to visualize and communicate. The spatial component is however still underutilized, and out-of-the box GIS solutions are needed to address the vast needs of this industry. With the surface barely scratched, there is an enormous potential for geospatial technology employment and software development.

Decommissioning – field data from earlier phases of the oil field life cycle centralized in enterprise GIS help to remove infrastructure and assets, and recover the site for land use.

Benefits of GIS in Oil and Gas 

• Empowers decision making – which acreage or play to enter, how to shorten portfolio workflows, how to plan the optimal pipeline route, integrate results of seismic survey, planning emergency response, better management of facilities, manage pipeline outage and leaks, etc.
• Supports future action and ongoing exploration activities – By standardizing processes and reducing technical uncertainty, GIS improves exploration efficiency. The GIS framework models a consistent exploration processes across all assets within the company. This supports a consistent, auditable corporate prospect portfolio, for ongoing portfolio decisions.
• Increased efficiencies – multi disciplinary data integration for risk assessment and uncertainty, better access for cutting wasteful downtime, optimized maintenance schedules; monitoring and analysis of daily fleet movements in real time, least cost path analysis for pipeline routing, standardized portfolio workflows, cutting down decision cycle times, etc.
• Cost saving – an estimate of 10-30 per cent cut in operational costs, prevention and management of incidental or accidental costs, efficient pipeline and fleet management saves costs, optimized drilling and operation workflows enhances ROI, and so on.
• Seamless management with a real-time mapping visualization and analysis of remote /offshore sites, operations and assets
• Improved communication across spatially dispersed locations
• Record keeping – the huge data loaded in centralized GIS builds a strong framework for managing data with full transaction support and reporting tools.

Conclusion


The Oil and Gas industry has been a comparative late comer to GIS. However, it is fast emerging as the industry with the highest potential of GIS application through the entire life-cycle. What’s more, it enables a seamless integration of geospatial technologies like UAV, sensors, and existing computer systems within the GIS framework. This is helping companies compete in the global race to unlock new energy sources and maximize value from its assets.

CGG Embraces “GIS-Lite” Capabilities for Oil and Gas Arena

By George Demmy



From data on new drilling opportunities to monitoring exploration and collaborating with field workers, sharing timely and accurate location information is critical for the oil and gas industry.

Though, for many years, this critical business data intelligence ended up being used in a paper map or a static image in a PowerPoint slide. While GIS is a powerful platform for scientists, mapping professionals and cartographers, the reality is that not everyone who needs geospatial data is trained in GIS software.

However, TerraGo is seeing a shift where many progressive firms have found a way to increase the return on their GIS investments by using GeoPDFs to share free, interactive, lightweight GIS applications with people not trained in GIS, including decision-makers, analysts, scientists, engineers and field personnel.



Directions Magazine recently ran a feature article which discusses how CGG, a geosciences leader in the oil and gas sector, has leveraged these “GIS-Lite” solutions since 2007.

The organization has been compiling, analyzing and sharing geospatial data though the use of TerraGo GeoPDF and TerraGo Toolbar in its Multi-Physics business line, which provides expertise in potential fields and electromagnetics to complement seismic data in exploration workflows.

“ArcGIS is great, but not everyone has the software or the training to effectively use it,” said James Cokinos, GIS coordinator and geologist for Multi-Physics at CGG, in the article. “By complementing our ArcGIS work with TerraGo GeoPDFs, we are able to easily share our GIS information, along with lightweight GIS features like layer control, measurements and markup, while providing a forum for sharing feedback with everyone, whether they have ArcGIS or not. The nice thing for the end user is that it’s all accessed with free, universally available software in Adobe Reader.”

The article also highlights how, when CGG produces a GeoPDF, the company goes beyond just making a map to print. Cokinos and his team add various vector layers and customize the layers to help visualize and emphasize the most relevant information for its oil and gas customers.

CGG is a prime example of today’s organizations needing to leverage a blend of heavy and light geospatial capabilities. It will always need to use high-caliber GIS systems, mixed in with the use of lighter-weight systems for professionals not trained in GIS.

Where are all the GIS Jobs Going?

There have been several layoffs over the last few months due to declining oil and gas prices and trends toward more cost effective management practices. This includes many mergers in the Oil and Gas sector by operators and vendors alike.

This has left many GIS professionals looking for jobs. For those looking in the current market right now, it is imperative to consider market trends and where the field is going. As companies merge, layoffs are typical. This occurs mostly where there is department overlap and overhead cost consideration. GIS falls directly into this category.

This trend can be seen in the following mergers of Oil, Gas and Energy companies:

• Over the last two years Kinder Morgan, Inc. (KMI) has worked on the merger of all Kinder Morgan companies under KMI into one of the largest conglomerates in North America and the $3 Billion Hiland Acquisition.
• The merger of Palmetto Engineering of Dallas, Texas and CT&T, of North Little Rock, Arkansas last year.
• Energy Transfer Company just completed its merger with Regency Energy Partners and has been trying to buy Williams with rumors for merger deals with Oneok and Targa resources.
• Williams is already planning to merge Williams Cos. with Williams Partners, LP and is also increasing its equity interest in Utica East Ohio Midstream LLC.
• The recent acquisition of Eagle Mapping Information Systems, Inc. by G2 Partners last December.

This is just the start of these large mergers as more companies try to stave off debt and compete in the international markets. Despite this growing trend The Bureau of Land Management expects a projected 14% job growth, from 54,000 jobs in 2012 to 61,300 jobs by 2022. Despite there being fewer companies to offer jobs. This is due to easier access of geospatial data by the regular consumer through products such as Google Earth and ArcGIS Online. The data used to fuel these applications from behind the scenes will still need creators, administrators and analysts.

As the Geospatial community career trend moves to online web mapping, cloud hosting and 3D visualization more people will have the ability to use geospatial data. OGSpace forecasts a decline in the average power user or the typical GIS analyst position as the end user has easier access to create, process, analyze and report on their own data relevant to their work. As the field grows and changes, it will require more specific knowledge, skills and abilities that many professionals have not developed over the changing technology – whether through habit or budget restraints.

With the availability of free training, GIS offered in high school, and open source GIS platforms becoming more available, the newer workforce will be more adapt to the advancing technology. This promotes a competitive environment as the retirement of older workers positions will need to be filled. While the older generation will still be able to compete for jobs, it will require more personal investment and re-education to the evolving industry standards as less companies exist to apply to.
