Abstract:
1. A method of establishing a fluid communication in a well between a formation and a tubular casing, said method comprising the steps of: providing a casing, wherein the casing comprises: pumping a fluid train into an annulus between the casing and the formation, wherein the fluid train comprises at least a settable material and a compliant sealant, and wherein the fluid train is configured to provide that after the fluid train is pumped into the annulus a layer of the compliant sealant is disposed in the annulus on top of a layer of the settable material; fracturing the layer of the settable material after the settable material has set, wherein the step of fracturing the layer of the settable material comprises applying a force to the protruding elements; and wherein the fractured settable material blocks the passage of formation sand and other solid particles through the openings and the layer of the compliant sealant prevents fractures spreading up the annulus beyond the layer of the settable material.
