Debris control systems, apparatus, and methods

Abstract

A debris control system comprises a first ported sub and a second ported sub attached to a casing and disposed in a wellbore, such that the first ported sub is disposed at a depth that is deeper than the depth at which the second ported sub is disposed. The first ported sub is to move debris from the wellbore when it is actuated and a first fluid is pumped through it. The second ported sub is to enable conducting a diagnostic fracture injection test (DFIT) when a second fluid is pumped through it. Additional apparatus, methods, and systems are disclosed.

What is claimed is: 
     
         1 . A method, comprising:
 pumping a first fluid through a first ported sub to remove debris from a wellbore in which a casing attached to the first ported sub is disposed, to provide a cleaned wellbore;   sealing the wellbore at a first depth; and   pumping a second fluid through a second ported sub to conduct a diagnostic fracture injection test in the cleaned wellbore, wherein the first depth is deeper than a second depth at which the second ported sub is attached to the casing.   
     
     
         2 . The method of  claim 1 , further comprising:
 running the casing into the wellbore prior to pumping the first fluid.   
     
     
         3 . The method of  claim 1 , further comprising:
 enabling fluid communication between the wellbore and a formation via ports on the first ported sub prior to pumping the first fluid.   
     
     
         4 . The method of  claim 1 , further comprising:
 enabling fluid communication between the wellbore and a formation via ports on the second ported sub prior to pumping the second fluid.   
     
     
         5 . The method of  claim 1 , wherein the first fluid comprises a solvent cleanout fluid. 
     
     
         6 . The method of  claim 1 , wherein the second fluid comprises formation compatible fluid. 
     
     
         7 . A system, comprising:
 a first ported sub attached to a casing and disposed at a first depth in a wellbore, wherein the first ported sub is to pass debris from the wellbore when the first ported sub is actuated and a first fluid is pumped through the first ported sub; and   a second ported sub disposed at a second depth in the wellbore, wherein the first depth is deeper than the second depth, the second ported sub to enable conducting a diagnostic fracture injection test when a second fluid is pumped through the second ported sub.   
     
     
         8 . The system of  claim 7 , further comprising:
 a first landing collar disposed at a third depth that is deeper than the first depth.   
     
     
         9 . The system of  claim 8 , further comprising:
 a wiper dart to pass through the wellbore to control the amount of debris in the wellbore.   
     
     
         10 . The system of  claim 9 , further comprising:
 a second landing collar disposed at a fourth depth that is between the first and second depths, wherein the second landing collar has an inner diameter greater than an inner diameter of the first landing collar, such that the wiper dart passes through inner diameter of the second landing collar.   
     
     
         11 . The system of  claim 10 , further comprising:
 a wiper plug to land in the second landing collar so as to create a seal in the wellbore.   
     
     
         12 . The system of  claim 7 , wherein at least one of the first ported sub or the second ported sub comprises a hydraulically actuated sliding sleeve. 
     
     
         13 . A method, comprising:
 installing a plurality of tools on a casing, the plurality of tools comprising a first ported sub and a second ported sub;   running the casing into a wellbore;   performing a completion operation; and   opening the first ported sub to pass debris from the wellbore, prior to opening the second ported sub to conduct a diagnostic fracture injection test.   
     
     
         14 . The method of  claim 13 , wherein opening the first ported sub comprises:
 applying hydraulic pressure to the first ported sub, so as to shear one or more shear fasteners.   
     
     
         15 . The method of  claim 13 , further comprising:
 pumping a solvent into the wellbore to pass debris from the wellbore through the first ported sub.   
     
     
         16 . The method of  claim 13 , further comprising:
 opening the second ported sub after the first ported sub is plugged.   
     
     
         17 . The method of  claim 13 , further comprising:
 sealing the wellbore at a first depth, wherein the first ported sub is located at a second depth that is equal to, or deeper than, the first depth.   
     
     
         18 . The method of  claim 17 , wherein sealing the wellbore comprises:
 landing a wiper plug at a landing collar disposed at the casing between the first ported sub and the second ported sub, wherein the plurality of tools comprises the landing collar.   
     
     
         19 . The method of  claim 17 , further comprising:
 opening the second ported sub after sealing the wellbore, wherein the second ported sub is disposed at a third depth, wherein the first depth is deeper than the third depth.   
     
     
         20 . The method of  claim 17 , further comprising:
 performing a diagnostic fracture injection test or a hydraulic fracturing treatment using the second ported sub.
