Stimulation and injection system

Abstract

An apparatus for introducing a vapor-containing stream into underground geological formations, pumps, conduits or tanks comprising; at least one vapor-containing stream generator having a liquid hydrogen peroxide fuel introduction zone, a catalyst zone and a zone for creating a backpressure of a vapor-containing stream formed by the generator; a conduit for introducing the liquid hydrogen peroxide fuel with said liquid hydrogen peroxide having a concentration of from 7095 weight percent into the vapor-containing stream generator; means for directing the vapor-containing stream into the formation, pump, conduit or tank and means for introducing a fluid into the formations, pumps, conduits or tanks.

1 . An apparatus for introducing a vapor-containing stream into underground geological formations, pumps, conduits or tanks comprising; 
 at least one vapor-containing stream generator having a liquid hydrogen peroxide fuel introduction zone, a catalyst zone and a zone for creating a backpressure of a vapor-containing stream formed by the generator;    a conduit for introducing the liquid hydrogen peroxide fuel with said liquid hydrogen peroxide having a concentration of from 70-95 weight percent into the vapor-containing stream generator; means for directing the vapor-containing stream into the formation, pump, conduit or tank and means for introducing a fluid into the formations, pumps, conduits or tanks.    
   
   
       2 . The apparatus according to  claim 1 , further comprising means for introducing a water-containing fluid into the formation, pump, conduit or tank downstream of the means for directing the vapor-containing stream into the formation, pump, conduit or tank.  
   
   
       3 . The apparatus of  claim 1 , wherein the vapor-containing stream is at a temperature of at least about 212° F.  
   
   
       4 . The apparatus of  claim 1 , further including means for flushing the conduit as well as the formation, conduit, pipe or tank prior to introducing the vapor-containing stream into the formation, conduit, pipe or tank.  
   
   
       5 . The apparatus according to  claim 1 , further comprising valve-means in the conduit for venting to atmosphere said vapor-containing stream.  
   
   
       6 . The apparatus according to  claim 5 , further comprising a second valve-means for cooperating with the valve-means to effect flow of the vapor-containing stream into the conduit, pipe, conduit or tank with concomitant discontinuance of venting flow.  
   
   
       7 . A process for introducing a vapor-containing stream into a geological formation, a pump, a conduit or a tank for effecting stimulation of flow of material in the formation, pump, conduit or tank comprising: 
 (a) introducing hydrogen peroxide having a concentration of from 70 to 95% into at least one vapor-containing stream generator;    (b) passing the hydrogen peroxide into a catalyst zone of at least one generator containing a catalyst adapted to decompose the peroxide to generate a vapor-containing stream;    (c) introducing the vapor-containing stream from at least one generator and a fluid to enhance the flow of material from said formation, pump, conduit or tank; and    (d) enhancing the flow of material in the formation, pump, conduit or tank.    
   
   
       8 . The process of  claim 7 , wherein the vapor-containing stream is at a temperature of at least about 212° F.
