Laboratory Field Capabilities Where You Operate

SPL Williston brings analysis directly to your operation with truck-mounted field equipment and local technicians — reducing transit time and delivering results when decisions can’t wait.

  • Mobile Gas Chromatography — Truck-mounted sample conditioning systems perform on-site compositional analysis and dew point measurement with real-time results across Bakken Basin facilities and pipelines.
  • Mobile Vapor Pressure Testing — Multiple truck-mounted units conduct on-site vapor pressure testing to ASTM D6377 at your facility or pipeline location.
  • On-Site Sample Collection — Local SPL technicians can be deployed to collect any sample type at any location, maintaining chain of custody from collection through final reporting.

Three things: certified equipment, trained people, and the depth to know the difference between a proving report that’s complete and one that’s right. SPL’s SVPs ball provers are  third-party certified per API MPMS, traceable, and defensible. Beyond the equipment, SPL’s measurement team includes SMEs who actively contribute to the development of API MPMS standards. That level of technical involvement means our team operates with an understanding of custody transfer measurement that goes well beyond procedural compliance.
