Systems and methods to deploy a chemical inhibitor in an oil or gas well

Abstract

The disclosure relates to systems and methods to deploy a chemical inhibitor (e.g., a scale inhibitor, a corrosion inhibitor, a biocide, a wax control substance, an asphaltene control substance) in an oil well.

What is claimed: 
     
         1 . A system, comprising:
 a support component;   a first container supported by the support component, the first container comprising:
 a top face comprising a plurality of openings; 
 a bottom face comprising a plurality of openings; 
 a side face; 
 an interior region defined by the top face, the bottom face and the side face; and 
 a first chemical inhibitor disposed in the interior region of the first container. 
   
     
     
         2 . The system of  claim 1 , wherein the support component comprises a gauge hanger. 
     
     
         3 . The system of  claim 1 , wherein the first chemical inhibitor comprises a member selected from the group consisting of a scale inhibitor, a corrosion inhibitor, a biocide, a wax control substance, and an asphaltene control substance. 
     
     
         4 . The system of  claim 1 , wherein the first chemical inhibitor comprises an encapsulated chemical inhibitor. 
     
     
         5 . The system of  claim 1 , further comprising a wellbore, wherein the support component and the first container are disposed within the wellbore. 
     
     
         6 . The system of  claim 5 , wherein the wellbore is in fluid communication with an underground reservoir. 
     
     
         7 . The system of  claim 6 , wherein the system is configured so that, during use of the system, a fluid produced from the underground reservoir is in fluid communication with the interior region of the first container so that the fluid interacts with the first chemical inhibitor. 
     
     
         8 . The system of  claim 7 , further comprising a horizontal well between the underground reservoir and the wellbore so that, during use of the system, the fluid flows through the horizontal well before entering the wellbore. 
     
     
         9 . The system of  claim 1 , wherein the side face of the first container comprises a plurality of openings. 
     
     
         10 . The system of  claim 1 , further comprising a second container supported by the support component, the second container comprising:
 a top face comprising a plurality of openings;   a bottom face comprising a plurality of openings;   a side face;   an interior region defined by the top face, the bottom face and the side face; and   a second chemical inhibitor disposed in the interior region of the second container.   
     
     
         11 . The system of  claim 10 , wherein the second chemical inhibitor comprises a member selected from the group consisting of a scale inhibitor, a corrosion inhibitor, a biocide, a wax control substance, and an asphaltene control substance. 
     
     
         12 . The system of  claim 10 , wherein the first container is between the support component and the second container. 
     
     
         13 . The system of  claim 1 , wherein at least one of the following holds:
 a density of the plurality of openings in the first container is from 4 openings/cm 2  to 400 openings/cm 2 ; and   a diameter of the plurality of openings of in the first container is from 0.5 mm to 5 mm.   
     
     
         14 . A method, comprising:
 disposing a system comprising a first container supported by a support component into a wellbore, the first container having an interior comprising a first chemical inhibitor; and   flowing a fluid from an underground formation into the interior of the first container so that the fluid interacts with the first chemical inhibitor.   
     
     
         15 . The method of  claim 14 , wherein the first chemical inhibitor comprises a member selected from the group consisting of a scale inhibitor, a corrosion inhibitor, a biocide, a wax control substance, and an asphaltene control substance. 
     
     
         16 . The method of  claim 15 , wherein the system further comprises a second container within the wellbore, the second container being supported by the support component, the second container comprising a second chemical inhibitor,
 wherein the fluid is in fluid communication with the second chemical inhibitor during production.   
     
     
         17 . The method of  claim 16 , wherein the second chemical inhibitor comprises a member selected from the group consisting of a scale inhibitor, a corrosion inhibitor, a biocide, a wax control substance, and an asphaltene control substance. 
     
     
         18 . The method of  claim 14 , wherein the method further comprises monitoring a concentration of the first chemical inhibitor in the fluid after the fluid interacts with the first chemical inhibitor. 
     
     
         19 . The method of  claim 18 , further comprising, when monitoring the concentration of the first chemical inhibitor results in a determination that a concentration of the first chemical inhibitor in the fluid is below a predetermined level:
 removing the system from the wellbore;   disposing additional first chemical inhibitor into the first container; and   disposing the system into the wellbore.   
     
     
         20 . The method of  claim 14 , further comprising disposing the first container and the support component into the wellbore using a member selected from the group consisting of a slickline or a coiled tubing.
