    Abstract: Provided are systems and methods for forming a casing liner in a wellbore of a hydrocarbon well. The forming including 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, conducting a downhole lining operation including operating the casing liner print head to eject casing liner integrated structure material into the annular region to form, in the annular region, a casing liner integrated structure including contiguous voids formed in the casing liner integrated structure material, and depositing a cementitious material into the contiguous voids formed in the casing liner material to form, in the annular region, a casing liner including the casing liner integrated structure material and the cementitious material.

    Abstract: Provided is a wellbore casing liner printing system that includes a casing liner print head adapted 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 and adapted 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 including 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 adapted to eject a first casing liner material into the annular region and the second set of printing nozzles adapted to eject 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.

    Abstract: The present disclosure relates to the creation of emulsifiers for use in an oil-based drilling mud. The disclosed emulsifiers may be created by the reaction of synthetic linear saturated fatty acids and polyamines under the conditions specified. The synthesized product may be used as a replacement for the wetting agent in conventional muds. Further improvements in conventional drilling muds are also disclosed where the synthesized product is used to replace incumbent wetting agents and the primary emulsifiers are replaced by synthetic fatty acids.
