or other pipe string can readily be assembled from conventional units the reduced inner diameter section 12 is preferably a section of pipe having a thicker wall but substantially the equal outer diameter the insert for cementing and the cement guide shoe can be conventionally available items such a casing string can be cemented or otherwise grouted in place by means of materials and procedures which are conventionally known and available fig3 shows a subsequent stage in which the pipe string has been grouted into the borehole and preferably cleaned out by means of running a scraper through the upper portion of the casing and the reduced diameter section 12 in general a drill string is preferably run in to drill out the cement insert and shoe and extend a borehole section 15 on into a reservoir interval 16 in which the liner is to be located however by using a cement basket or the like where desired the well can be initially drilled to the depth necessary to accommodate the liner below the casing string fig4 shows the final stage of installing a well liner suspended from the present liner hanger the brass like sleeve 2 is wedged into the reduced diameter portion 12 of the surrounding pipe string 11 and the liner 18 is hung below the expansion joint provided by the sleeve 5 of the lower element of the hanger fig5 shows a preferred method of connecting.
