Wellbore Casing Liner Printing

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, the casing liner print head comprising:
• a first set of printing nozzles arranged in series in a radial direction;
• and
• a second set of printing nozzles arranged in series in the radial direction, and offset from the first set of printing nozzles;
• and
• rotating the casing liner print head within the annular region and depositing material into the annular region to form a casing liner in the annular region, the depositing comprising the first set of printing nozzles ejecting a first casing liner material into the annular region and the second set of printing nozzles ejecting a second casing liner material into the annular region to form the casing liner of the first casing liner material and the second casing liner material.

A wellbore liner printing system comprising:

• a casing liner print head configured to be disposed in an annular region located between a tubular member disposed in a wellbore of a hydrocarbon well and a wall of the wellbore and configured to rotate within the annular region and deposit material into the annular region to form a casing liner in the annular region, the casing liner print head comprising:
• a first set of printing nozzles arranged in series in a radial direction;
• and
• a second set of printing nozzles arranged in series in the radial direction, and offset from the first set of printing nozzles,
• the first set of printing nozzles configured to eject casing cement into the annular region and the second set of printing nozzles configured to eject integrated structure material into the annular region to form the casing liner of the casing cement and voids in the casing cement that are defined by the integrated structure material.
