In accordance with one or more embodiments of the present disclosure, a drilling fluid may include a base fluid and one or more formaldehyde-based resins. The drilling fluid may further comprise one or more water-insoluble acid catalyst precursors or the reaction products of such water-insoluble acid catalyst precursors. The present disclosure also describes sealed subterranean petroleum formations that include such drilling fluids and methods for sealing subterranean wellbores by utilizing such drilling fluids.

In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises, following the firing, injecting a mixture of a mastic component and a particulate metal component from an end of the ceramic unit into selected ones of the cells so as to block the selected cells over at least a part of the lengths thereof while maintaining all of the walls of the ceramic unit, and curing the injected material to render the injected material solid.

A method of treating a pond, lake or other body of water to improve the retention of water includes treating the ground at the bed of the pond with bentonite clay, a super absorbent polymer, a polysaccharide, and a polymer flocculant. The bentonite clay can be granulated #16 Wyoming bentonite clay, the super absorbent polymer can be granulated polyacrylamide, the polysaccharide can be granulated carboxy methyl cellulose, and the polymer flocculant can be a high-performance polymer flocculant, such as 2-Propenoic Acid, polymer with 2-Promenamide, sodium salt 90-100%.
