Abstract
A portable resilience testing apparatus for lost circulation materials (LCMs) is provided. The portable resilience testing apparatus includes a test cell and a probe that moves and applies a force to a sample of LCM contained in the test cell. The portable resilience testing apparatus may be used to perform a compression cycle and decompression cycle on the LCM sample. A coefficient of resilience of the LCM sample is determined from the desorbed strain energy released during the decompression and the absorbed strain energy stored during the compression cycle. A method of determining the coefficient of resilience is also provided.
