Abstract: Provided are systems and method for casing a wellbore of a hydrocarbon well. The casing including disposing a casing print head in a wellbore of a hydrocarbon well, and conducting a downhole casing operation including operating the casing print head to eject casing material to form a casing tubular in the wellbore, and operating the casing print head to eject casing liner material into an annular region located between the casing tubular and a wall of the wellbore to form a casing liner in the annular region, the casing tubular and the casing liner forming a casing of the wellbore.

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.

Abstract: According to one or more embodiments of the present disclosure, a drilling fluid may comprise one or more deep eutectic solvents in an amount greater than or equal to 70 wt.% based on the total weight of the drilling fluid. Each deep eutectic solvent may comprise at least one hydrogen bond acceptor compound and at least one hydrogen bond donor compound. A molar ratio of the total moles of the hydrogen bond donor compounds to the total moles of the hydrogen bond acceptor compounds in each deep eutectic solvent may be from 0.1 to 1.0. The drilling fluid may have a density greater than or equal to 200 kg/m3. The drilling fluid may have a viscosity greater than or equal to 0.5 Pa•s when measured at 25 °C. Methods for drilling wells in subterranean formations using the drilling fluid are also disclosed.
