Pipeline Information Management

Pipeline Route, Permits, Consents, Construction & Handover

The three major verticals of Oil & Gas industry operations are Upstream, Midstream & Downstream. Midstream mainly includes activities related to transportation ( by Pipeline, Rail, Oil Tankers, Truck, Barge), storing, processing and wholesale marketing of crude or refined hydrocarbon products.

On today’s ENP Technologies blog, we’ll touch on a few things you can do to make sure your Pipeline Project has a positive outcome.

Onshore Pipeline Route Selection –

Pipeline route selection is a critical milestone in a Midstream project to identify the preferred route. Before coming to the preferred route there are always some alternative routes that are assessed of the critical engineering and environmental issues, permitting requirements and risks associated with those routes.  Publicly available aerial and topographic information from (e.g., Google Earth)are utilized to identify the key areas.  

Proposed pipeline segments in the direction of flow along the line is identified and marked.  The data available from various geospatial and mapping applications are often inserted into such kmz file to be reviewed.

In many cases the Pipeline consists of two segments : Onshore & Offshore. Both pipeline segments must navigate through the areas of greenfield or brownfield. It can be areas of existing oil and gas infrastructure coming out of bay/ Gulf of Mexico. Often that territory / coastline is marsh land areas. The available trace amount of relatively dry land in those area is occupied by either a civil infrastructure (roads) or residential settlements with a multitude of the individual landowners. Such area is perceived to be environmentally sensitive, due to ongoing coastline dissolution and oyster industry.

Pipeline route selection will need to balance aspirations for the most direct path with the necessity to minimize environmental damage, consider interests of multiple landowners, and consider constructability matters including various crossings.

Such reviews facilitate the development of alternate routes and review process to generate review register with the potential questions on that route selection process.

Aerial Survey

Further to identify potential critical issues and risks. A detailed aerial survey through helicopter overflight is conducted to get clear understanding of the potential engineering and environmental constraints, topographical terrain difficulties, critical waterbody crossings, new construction along the route, access roadways, bridges, and staging areas.

Often the initial topographical data generated is in the form of maps and contours. But these videos of recorded flight route are in HD format and extremely bulky. Often converted into different formats. The pressing need is to be able to view them through different devices. The IM Resources generally convert and upload these files into SharePoint / shared drive to be accessed.
