Abstract
A slip assembly apparatus is adapted (i) to be deployed into a wellbore (ii) to prevent axial movement of a downhole tool assembly in the wellbore when the slip assembly apparatus is actuated and external forces are imposed on the downhole tool assembly; (iii) to allow fluid flow past the slip assembly apparatus within the wellbore when the slip assembly apparatus is actuated or non-actuated; and (iv) to allow release of the slip assembly apparatus by use of a release load that is less than the axial capacity of the deployment mechanism. Different embodiments of the invention contain features such as claddings and treatments for surface hardness and wear resistance, and grooves or flutes for enhancing fluid flow between the outer diameter of the slip assembly and the inner diameter of the well casings.
