Extra shallow depth packer to avoid isolate the reservoir with cement

Abstract

Systems and methods for an extra shallow depth packer to avoid isolating the reservoir with cement include installing a shallow packer element in a well. Hydraulic oil is supplied to the shallow packer element. The shallow packer element is pressure tested. A tubing casing annulus (TCA) is monitored for leaks. The shallow packer element is inflated upon detecting a leak in the TCA.

1 . A method comprising:
 installing a shallow packer element in a well;   supplying hydraulic oil to the shallow packer element;   pressure testing the shallow packer element;   monitoring a tubing casing annulus (TCA) for leaks, wherein the leaks are located on a tubing, and a fluid communication exists between the tubing and the TCA; and   upon detecting a leak in the TCA, inflating the shallow packer element.   
     
     
         2 . The method of  claim 1 , wherein the hydraulic oil is supplied to the shallow packer element through a control line. 
     
     
         3 . The method of  claim 2 , wherein the hydraulic oil is pressurized. 
     
     
         4 . The method of  claim 1 , wherein a pressure sensor is used to measure pressure in a borehole. 
     
     
         5 . The method of  claim 1 , wherein a pumping well test is used to pressure test the shallow packer element. 
     
     
         6 . The method of  claim 1 , wherein a buildup test is used to pressure test the shallow packer element. 
     
     
         7 . The method of  claim 1 , wherein a pressure test of the shallow packer element comprises inflating the shallow packer element. 
     
     
         8 . The method of  claim 1 , wherein the shallow packer element connects to a top connection and a bottom connection. 
     
     
         9 . The method of  claim 1 , wherein the hydraulic oil inflates the shallow packer element. 
     
     
         10 . The method of  claim 1 , wherein the inflated shallow packer element isolates the TCA. 
     
     
         11 . A system comprising:
 casing installed within a borehole;   tubing installed within the casing, wherein the tubing has a smaller diameter than the casing such that an area between the casing and the tubing forms a tubing casing annulus (TCA);   a shallow packer element configured to be inserted into the casing within the TCA;   a control line for providing hydraulic oil to the shallow packer element to inflate/deflate the shallow packer element; and   a pressure sensor for detecting a pressure of the shallow packer element, wherein the pressure sensor detects leaks located on the tubing, and a fluid communication exists between the tubing and the TCA,   wherein hydraulic oil is provided to the shallow packer element based on the pressure detected by the pressure sensor.   
     
     
         12 . The system of  claim 11 , wherein the hydraulic oil is supplied to the shallow packer element through the control line. 
     
     
         13 . The system of  claim 12 , wherein the hydraulic oil is pressurized. 
     
     
         14 . The system of  claim 11 , wherein a borehole sensor is used to measure pressure in a borehole. 
     
     
         15 . The system of  claim 11 , wherein a pumping well test is used to pressure test the shallow packer element. 
     
     
         16 . The system of  claim 11 , wherein a buildup test is used to pressure test the shallow packer element. 
     
     
         17 . The system of  claim 11 , wherein a pressure test of the shallow packer element comprises inflating the shallow packer element. 
     
     
         18 . The system of  claim 11 , wherein the shallow packer element connects to a top connection and a bottom connection. 
     
     
         19 . The system of  claim 11 , wherein the hydraulic oil inflates the shallow packer element. 
     
     
         20 . The system of  claim 11 , wherein the shallow packer element, upon inflation, isolates the TCA.
