1. A system for forming a casing liner in a wellbore of a hydrocarbon well, the 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 comprising a row of nozzles configured to eject casing liner integrated structure material into the annular region;
a cylindrical collar disposed over the casing pipe, wherein the cylindrical collar and the casing liner print head are configured to rotate together about the casing pipe, the row of nozzles arranged in series along a lateral axis extending radially from the cylindrical collar; and
a well control system comprising a processor and non-transitory computer readable storage medium comprising program instructions stored thereon that are executable by the processor to cause the following:
conducting a downhole lining operation comprising operating the casing liner print head such that the cylindrical collar and the casing liner print head rotate together about the casing pipe and the row of nozzles ejects 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,
wherein the elongated voids comprise elongated voids extending in a radial direction more than in a longitudinal direction in the annular region,
wherein the lining operation comprises ejecting an integrated structure material to form the elongated voids in the casing liner material, and
wherein the integrated structure material has a Young's Modulus that is less than a Young's Modulus of the casing liner material.
