Abstract
Methods of forming permeable sand screens in long, open hole well bores within fluid producing zones are provided. The methods basically comprise the steps of placing a perforated pipe in the open hole well bore, providing a hardenable composition which after being placed in a desired location cures into a hard mass, placing the hardenable composition in the well bore adjacent to the fluid producing zone within the interior of the perforated pipe therein, between the perforated pipe and the walls of the open hole well bore and within voids or fractures in the producing zone, causing the hardenable composition to cure into a hard permeable mass and drilling the hard permeable mass out of the interior of the perforated pipe.
