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.
Claims20
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.
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.
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.
