 At Lonquist Engineering, we distinguish ourselves by offering reliable engineer-supervised testing at lower costs and with faster turnaround times than our competitors. With our multiple offices, laboratory locations and mobile laboratory, Lonquist is nearby and ready to assist with your next project.

API 19C / ISO Frac Sand Evaluation

Lonquist has been a leader in frac sand testing for many years. Our diligent focus on quality and procedural control in our labs ensures that test results are accurate and verifiable. Our engineers and geologists don’t just crank out test results; they really understand what the data shows and are able to consult on material viability, mining and processing adjustments, or additional industries where your particular product may be in demand.

In the age of abundant in-basin proppant availability our test labs have also proven invaluable in quality and in-spec verification at well sites prior to frac’ing operations.

Mobile Testing Laboratory

We are proud to offer our brand new mobile laboratory for your next project. Our 40 ft gooseneck trailer is fully equipped to operate independently and continuously in any location. The mobile laboratory can be run on shore power or on its generator 24/7. It is also equipped with a water recycling system, eliminating the requirement for fresh water connections. Our experienced technicians are well trained in material sampling, identifying operational inefficiencies, QA/QC laboratory training, and safe work practices.

Often times the logistics, cost, and delays associated with shipping many samples for testing can reduce the efficiency of mining initialization, plant commissioning and optimization, and pre-frac QC efforts at wellsites. Our mobile lab solves these problems.

  • New pit / wet plant / dry plant calibrations and start-up

  • Existing pit / plant optimizations

  • Independent laboratory analysis for standardization of QA/QC testing procedures at mine site

  • Pre-frac testing of sourced proppants

    • Instantaneous verification of proppant specifications and quality prior to frac’ing operations at wellsite

    • Centralized QC testing of received material at port locations before shipment to offshore platforms
