The process comprises placement of centralizers around at least one section of fused porous refractory tubing which section has placed therearound at least one centralizer. A flexible tubing of a composition and strength sufficient to withstand the formation environment is connected to each section and one end of the tubing is connected to the production string. When in place, the fused refractory section excludes particulate matter from liquefied resources, particularly formation fines during the production of hydrocarbonaceous fluids.
