| titleOfInvention | Method for placement of blocking gels or polymers at specific depths of penetration into oil and gas, and water producing formations |
| abstract | This patent application relates to a process whereby a filter/sieve is produced by injecting the interactive chemicals used to form gels and polymers at reservoir temperatures independently and sequentially into a well in such a manner that the chemicals only come into contact with each other at the desired depth of penetration in the formation. At this location in the reservoir, which can be determined by appropriate calculation, the injection is stopped and the intermixed and superimposed chemicals are allowed to react to form the filter/sieve of a gel or polymer depending upon the nature of the individual chemicals injected. n Since no reaction takes place during the injection phase, premature gelation or polymerization cannot occur at any point other than where the chemicals come into contact each with the other. Furthermore, by using this placement process not only can the gel or polymer blockage, namely, the desired filter/sieve structure, be located at a depth of penetration (between four and thirty feet) where the velocity flow for either the injection or production of fluids into or from the reservoir interval is ideal for maintaining the blockage of water, but the thickness of the filter/sieve can also be predetermined by using appropriate volumes of the injected chemicals and nonchemical containing push volumes. |
