Latest Patents
Leonard V Grego holds a patent for a "Method for selectively closing an intermediate zone of a near wellbore." This method involves placing a drillable mechanical packer into the wellbore below the intermediate zone. The adjacent wellbore area is then cooled to a critical temperature between about 130°F to about 180°F. A novolac or resole-type phenolformaldehyde resin containing an acid catalyst is introduced into the wellbore, forming a solid platform over the packer and intermediate zone in approximately two hours. The critical temperature is maintained while a second resinous material containing an alkaline catalyst is placed into the wellbore, resulting in a steam-resistant solid gel that effectively closes the intermediate zone.
