PROCESS FOR CONSOLIDATING AND CONSOLIDATING FLUID FOR USE IN SUCH PROCESS

摘要

A permeable water-containing earth formation is consolidated while a borehole is being drilled into that formation by circulating as a drilling fluid an oil solvent solution containing a mixture of an epoxide and imine that forms an epoxy resin when mixed with water and a suspension of finely divided solid particles that forms a filter-cake permitting a selected amount of filtrate invasion into a permeable earth formation.
