Abstract

A tool for use in a wellbore comprising a seal assembly and a cone member configured to force the seal assembly radially outward into engagement with the wellbore. A shear thickening fluid is disposed within an area formed between the seal assembly and the cone member. The shear thickening fluid is configured to prevent relative movement between the cone member and the seal assembly when the shear thickening fluid is changed from a substantially fluid state to a substantially solid state due to a sudden force applied to the shear thickening fluid, by release of a sheared mechanism for example.
