          Appeal No. 2000-0053                                                        
          Application 08/829,863                                                      


               We reverse the aforementioned rejection.                               
               Clay discloses a process which eliminates dead volume                  
          between the outlet and bottom of a storage tank and also                    
          restores the tank, and which differs from the appellants’                   
          claimed process only in that Clay does not combine                          
          unconsolidated solids with a gelation solution which is placed              
          in the tank (col. 1, line 62 - col. 2, line 17; col. 3, line                
          21 - col. 4, line 15).                                                      
               Sydansk (col. 1, line 66 - col. 2, line 24; col. 3,                    
          lines 22-36; col. 4, lines 35-60) and Smith (col. 1, line 57 -              
          col. 2, line 16; col. 2, lines 29-57; col. 3, lines 3-8) both               
          disclose processes for reducing the permeability of a high                  
          permeability region of a subterranean hydrocarbon-containing                
          formation, thereby improving the vertical and areal                         
          conformance of the formation, by injecting into the formation               
          a mixture of a gelation solution, which is essentially the                  
          same as that used by Clay, and an inert filler such as crushed              
          or naturally fine rock material or glass beads.                             
               The appellants argue that the processes of Sydansk and                 
          Smith are nonanalogous art with respect to the appellants’                  
          claimed process (brief, pages 8-12).                                        
                                          3
