Water and Infrastructure Solutions

Water Pipelines

Hillstone designs, owns and operates produced and flowback water pipeline systems, as well as freshwater delivery systems. Our systems include 24/7 SCADA monitoring and leak detection.

We have over 320,000 barrels per day of pipeline capacity at our assets in the Permian & Williston Basins.

Water Treatment and Recycling

With more than 100 million barrels treated and filtered in Texas, West Virginia, and Ohio, Hillstone is proficient and experienced in the treatment sector.  We have a patented Coagulization™ process that involves using mobile treatment units, each with up to 20,000 barrels per day of treatment capacity.  Our process integrates into existing client operations, and can be done concurrently with drill-out and flowback, either on-pad or near-field.  We have water treatment assets in the Permian Basin and Marcellus / Utica Shale.

Logistics Technology (ShaleApps)

ShaleApps™ is a logistics application that manages water trucking operations from end to end, with a 100% digital process that eliminates paper tickets. The ShaleApps process is designed by oilfield professionals to address the challenges of oilfield trucking, including inefficiencies in billing and tracking caused by paper ticket processes. ShaleApps’ novel approach is based on mobile technology that helps automate the tracking of trucks and water types, enabling more cost-effective decisions regarding fluid movement and leading to lower trucking costs as well as more accurate billing, accounting, and regulatory reporting.
