Pipeline Release Data Collection and Communication


A pipeline in the central plains of the U.S. released an estimated 21,000 bbls of crude oil. Antea Group was challenged by the client to assemble a team of specialists capable of effectively and efficiently collecting and communicating extent and migration data to key stakeholders. Due to the magnitude of the spill, spatial and environmental data needed to be collected electronically to expedite analysis and visualization. Furthermore, this incident required that laboratory data be managed by Antea Group to expedite analysis. Mapping and 3D modeling was also needed to assist with financial and remediation decision making.


Antea Group assembled a team to manage the site data, visualize the impact and remedial progress on the site, and model the site and remediation actions. The CAVe team supported the project by:

  • Performing data validation on all laboratory reports
  • Uploading 1,000 samples
  • Uploading 15,000 laboratory results
  • Using survey and in-field mapping data from ArcMobile to map the site
  • Migrating lithology data from 235 locations to be modeled in MVS
  • Migrating site base data to ArcGIS to prep the data in 3D
  • Utlizing LIF and boring data to model the extent of LNAPL in the subsurface in near real time
  • Using excavation extent and volumetric estimations from MVS to drive design and budget
  • Developing and delivering a conceptual system design for a supplemental SVE system in MVS to client via 3D PDF


The CAVe team provided the client team with data management, laboratory data validation, 3D lithologic and LNAPL modeling to assist in decision making and financial management as remediation was performed. Successes included real-time updates of LIF impact during investigation, which reduced the scope and schedule and achieved faster delineation. Use of 3D modeling and volumetrics provided client's management with modeled imagery of the extent of subsurface impact and changes over time.
