1. Crosshole Geophysical Tomography for a Tunneling Project

    RETTEW’s Geophysics team recently assisted a client with a tunneling project. The tunnel path was at a depth at which surface geophysics could not resolve potential small zones of concern, including low-stiffness weathered rock that might require special support, and water-bearing seams that could flood the opening. The required resolution could only be achieved using…

  2. Aquatic Resource Data Quality Validation

    A natural gas client experienced delays with permit reviews submitted by other consulting firms because of concerns with the quality and reliability of their wetland data. Permit applications submitted by RETTEW for the client did not have similar delays in review. As a result, RETTEW provided quality control (QC) field reviews of stream and wetland…

  3. Ohio River Water System Project

    Our client was looking for an innovative way to address their water needs for well completion activities. They enlisted the help of RETTEW to evaluate reliable sources and implement an effective conveyance system. The decided plan was to use a relatively uninterruptable source: the Ohio River. RETTEW developed and permitted a 20-mile pipeline route, designed…

  4. Pipeline Boundary Survey for 300 Line

    A natural gas client planned to upgrade its natural gas pipeline transporting raw material to the Northeast. The client’s goal was to enlarge the pipe size because of the increased demand in the region. Rugged terrain, incomplete records, and landowners not in agreement with the action were complicating the process. RETTEW’s survey group quickly mobilized…

  5. Pipeline Patrol and Inspection

    An exploration and production client acquired a 37-mile natural gas pipeline collection system that had been depressurized and shut down for more than two years. Prior to reactivating and bringing the gathering system online, the client needed to bring the pipeline into compliance with government and safety regulations. Although they typically provided these inspection services…

  6. Rover Pipeline

    The Rover Pipeline is a 711-mile transmission pipeline project that runs through portions of West Virginia, Pennsylvania, and Ohio, and extends 75 miles into Michigan. The mainly 42-inch pipeline will transport up to 3.25 billion cubic feet per day of domestically produced natural gas from multiple gas processing facilities to markets in the Central United…

  7. Ben’s Run Pumping Station

    As part of a large water system project, RETTEW provided services for two pumping facilities, with 20 miles of buried pipeline between them. The Ben’s Run Pumping Station withdraws water from the Ohio River via a submerged intake screen and intake pipe. The water is then collected in a wet well and pumped through 20-…

  8. Compressor Station 3D Scanning

    Turn-Key Specialists, Inc. (TSI), needed to obtain scans and 3D models for three separate compressor stations in Susquehanna County to help their client plan for additions to existing compressor stations and other potential construction activities. Because of our strong working relationship with TSI and the detail and quality of a previous high-definition scanning project we…

  9. High-Angle Utility Locating

    A high-pressure natural gas pipeline located in a right-of-way between two existing pipelines required inspection to evaluate potential flaws and any need for repair. Prior to excavation, the client needed to adhere to PA One Call requirements to mark their assets. A portion of the right-of-way was brush- and snow-covered steep terrain, creating accessibility challenges…

  10. Midstream Pipeline Rerouting

    A natural gas client acquired a planned pipeline, with routing and landowner agreements already in place. However, the existing route would take months of additional regulatory review time, and the client was eager to get the gas to market as quickly as possible. RETTEW tackled the many steps to reroute the pipeline, avoiding the extra…
