Features

  • Patent-pending design can comply with ASTM and ISO dimensions, ensuring compatibility with existing standards and comparability with typical vane tests.

  • Prototype tool offers rotation speeds ranging from 0.1°/s (ASTM VST) to 30°/s (FVST) up to 100Nm maximum torque.

  • Records pore water pressure (PWP) during vane insertion, rotation and retrieval, recording PWP’s generated by penetration and shear.

  • Downhole instrumentation provides results at low strengths and pore pressures.

  • Vane sizes available for testing shear strengths starting from less than 1 kPa.

  • Includes a temperature sensor and inclinometer package.
