  • Drying low rank coal and retarding spontaneous ignition
    Patent number: 4778482
    Abstract: Coal is rendered less subject to abrasion and disintegration by reducing it to a 0.2 to 0.5-inch particle size and drying it at a temperature of 200.degree. to 230.degree.

  • Oil reservoir permeability control using polymeric gels
    Patent number: 4658898
    Abstract: The permeability of subterranean oil-bearing formations is selectively reduced by the injection into the formation of the non-xanthan, anionic heteropolysaccharide S-130 produced by fermentation with a microorganism of the Alcaligenes species. The polymer forms shear-thinning, viscous solutions which selectively enter the more highly permeable regions of the formation and form a gel plug in them to reduce their permeability. The polymer forms gels which are stable under a wide range of reservoir conditions including high temperatures.
