A method of forming a casing liner in a wellbore of a hydrocarbon well, the method comprising:
- disposing a casing liner print head in an annular region located between a casing pipe disposed in a wellbore of a hydrocarbon well and a wall of the wellbore;
- and
- conducting a downhole lining operation comprising operating the casing liner print head to eject casing liner material into the annular region to form, in the annular region, a casing liner comprising elongated voids formed in the casing liner material.
A wellbore casing liner printing system comprising:
- a casing liner print head configured to be disposed in an annular region located between a casing pipe disposed in a wellbore of a hydrocarbon well and a wall of the wellbore, the casing liner print head configured to eject casing liner material into the annular region to form, in the annular region, a casing liner comprising elongated voids formed in the casing liner material.
A method of forming a casing liner in a wellbore of a hydrocarbon well, the method comprising:
- disposing a casing liner print head in an annular region located between a casing pipe disposed in a wellbore of a hydrocarbon well and a wall of the wellbore;
- and
- conducting a downhole cementing operation comprising operating the casing liner print head to eject casing cement into the annular region to form, in the annular region, a casing liner comprising elongated voids formed in the cementitious material.
