1. Geotechnical Evaluations for Freshwater Impoundments

    Many natural gas extraction sites rely on water impoundments to hold the major component of freshwater needed for resource extraction. Before designing or permitting these impoundments, clients must investigate subsurface conditions including soil, water table, and bedrock properties to assure constructability and meet regulatory design criteria. As part of an overall water sourcing program, RETTEW…

  2. Jonah Energy Annual Water Supply Sampling Program

    After acquiring various field assets for natural gas production, Jonah Energy needed to implement an annual groundwater sampling program to monitor potential changes in water quality associated with development. Their new properties included a natural gas production area of 24,000 acres and more than 1,500 active wells, as well as more than 100,000 undeveloped acres….

  3. Ohio Water Sourcing Program

    To maintain two current rigs, sustain two additional rigs, and support a robust drilling program in their Ohio and Utica holdings, our client needed a reliable water sourcing program. The first step in program development involved a shift from draining small, potentially unpermitted pond sources to more predictable sources like rivers and streams. Next steps…

  4. Spring Creek Surface Water Withdrawal

    A natural gas client planned to install and operate hundreds of wells in the Marcellus Shale Play. Each well is dependent on water sourcing to continue production, and the major water source for use was several miles away. The path to and from the source crossed federal, state, and private properties. To accommodate the client’s…

  5. Storage Tank Precision Monitoring 

    A natural gas client was building two 5-million-gallon steel tanks to store freshwater for its hydraulic fracking process. They also needed to monitor tanks for movement during a hydrostatic test of the structures. The project’s major challenge was scheduling; a survey crew needed to be on call around the clock for the duration of emptying…

  6. Surface Water Withdrawal Record of Disturbance

    A natural gas client was developing water sources to support its hydraulic fracturing operations. To fulfill its water needs, the client wanted to construct a surface water withdrawal near a dam, which required extra precautions in placement and structure as the dam was in poor condition. In addition, the pipeline size and routing were not…

  7. Temporary Waterline Construction

    An oil and gas client wanted a more efficient and cost-effective method of conveying source water to their drilling and completions operations in the Power River Basin, Wyoming, and decided to use temporary waterlines to eliminate the costly process of trucking in shipments of water. After completing hundreds of successful temporary waterlines projects for the…

  8. Water Sourcing and Planning

    A natural gas client was delving into a new shale play for the first time and had limited internal resources and knowledge of the state regulatory landscape. To add pressure, they were operating with an aggressive drilling and resource extraction schedule. To assist in getting their operations online quickly, the client needed heavy support to…

  9. Water Withdrawal Monitoring

    A natural gas client required ongoing water source monitoring to maintain water withdrawal operations. Endangered and threatened species inhabited a nearby wetland, prompting the Susquehanna River Basin Commission to require semi-annual monitoring of area plants, the macroinvertebrate community in the stream, and the stream’s flow volume and water chemistry. RETTEW’s integrated services provided design of…

  10. Osborne Storage Lagoon Design

    As a result of a Pennsylvania Department of Environmental Protection (PA DEP) consent order, the Oxford Area Sewer Authority imposed a moratorium on any new sewer connections to its system, halting all development in the area until they could install more effluent storage. The storage lagoon had been designed but was placed on hold due…
