Minimize Risk and Maximize Uptime. Complete Visibility for Your Facility.
Unplanned downtime during planned downtime at oil & gas facilities can cost millions—and most of it is avoidable. GPRS helps prevent utility strikes and costly delays by mapping underground infrastructure with unmatched accuracy.
Outdated or incomplete as-builts are a major risk. We confirm known utilities, identify unknowns, and give your team a clear picture of what’s below before excavation begins.
With GPRS, all findings live in one secure, digital platform called SiteMap®, —accessible anytime, from any device. Whether you're planning a turnaround, new construction, or routine maintenance, you’ll have the data you need to make informed, safe decisions.
See how GPRS can keep your next project on schedule.

GPRS Utility Locating Saves Gas Utility $500,000 per Mile in Costs
TASK:
Partner with Southern Connecticut Gas in a pilot program and cost savings analysis to compare their current utility data to GPRS’ findings in urban environments.
The Bottom Line:
GPRS’ 99.8% accurate utility locating in densely packed urban infrastructure and SiteMap® deliverables saved our client $500,000 per mile compared to their existing data capture methods.

Problem
Southern Connecticut Gas was realizing significant utility damage costs. After researching the problem, they found that their utility location and mapping information was classified as SUE Level D.

Solution
SCG partnered with GPRS to conduct utility locating and mapping on an urban ROW. Using GPRS’ Subsurface Investigation Methodology (SIM), we supported SUE Level B surveys with 99.8% accuracy. GPRS Project Managers employed GPR and EM locators to map water, sewer, electrical, gas, telecom, and other subsurface facilities. The data was uploaded with GPS positioning to SiteMap® for interactive, layered utility maps. After proving the concept, SCG expanded the program to large-scale urban projects and added video pipe inspection for sewer line assessments.

Benefits
The cost analysis was striking. By using GPRS for Level B SUE and SiteMap®, Southern Connecticut Gas saved $250,000 gross and $195,000 net for every 0.5 miles of urban pipeline work compared to existing SUE Level B data. GPRS verified both public and private utilities, finding discrepancies between public utility contractor mark-outs and actual locations. In one case, a fiber optic cable, unmarked and intersecting an excavation site, was located before it could be severed. By uploading all findings to SiteMap®, SCG can create a secure, shareable permanent utility record.*GPRS does not conduct SUE surveys. Our data capture supports SUE Level B.

GPRS Maps Tank Farm Utilities & Provides 3D Virtual Tour of 70+ Year-Old Refinery For Fire Suppression, Butane Rack Upgrades, and Tank Removal
TASK:
Provide accurate subsurface utility locating and mapping of 5.8 acres of a refinery tank farm so the operations and facilities managers could install a new fire suppression system, add butane racks, and remove a number of aboveground storage tanks safely.
.webp)
The Bottom Line:
GPRS provided accurate underground utility maps and a Walkthru 3D virtual tour including utility marks for 5.8 acres of tank farm so stakeholders and facilities managers could safely upgrade their fire suppression system, add butane racks, and maintain a 70-plus-year-old refinery.
Problem
The site, a previous brick factory, was repurposed as a refinery in the 1950s
There were no record drawings or as-builts available
The refinery is a major transport artery for the customer’s other gas & oil facilities
Solution
GPRS Project Managers scanned the refinery tank farm over a five-day period with ground penetrating radar (GPR) and electromagnetic (EM) locators to capture all available subsurface data
Significant underground utility congestion was discovered, particularly near the shop area, and numerous duct banks and conduits throughout
The GPRS-captured data was uploaded to SiteMap® (patent pending) via Real-Time Kinematic Positioning (RTK) for the most accurate geolocation & utility map available
Matterport 3D photogrammetry was utilized to provide a WalkThru 3D virtual tour of the site, capturing our utility markings
Findings were delivered via GPRS’ SiteMap application as a 2D CAD PDF of the utilities overlaid onto satellite imagery, interactive SiteMap digital utility maps, and WalkThru 3D
Benefits
Our customers now have their first comprehensive permanent utility record of their aging and complex refinery tank farm infrastructure
WalkThru 3D allows facilities managers and off-site stakeholders to review the existing site conditions and GPRS findings
RTK positioning provides extremely accurate geolocation of GPRS’ 99.8% accurate locates, so facilities and operations can excavate without fear of a utility strike
Complimentary SiteMap Personal access gives stakeholders, refinery operations, facilities managers, and their teams 24/7 access to their digitized utility maps and a 3D tour to streamline communications and collaboration
