Double-layered wellbore tubular assembly

A wellbore assembly comprising:

• a first wellbore tubular configured to be lowered into and installed within a wellbore, the first wellbore tubular having an inner diameter and defining a first hollow volume;
• a second wellbore tubular configured to be lowered into and installed within the first hollow volume of the first wellbore tubular, the second wellbore tubular having an outer diameter smaller than the inner diameter of the first wellbore tubular, wherein the second wellbore tubular installed within the first hollow volume defines a tubing-to-tubing annulus (TTA) between an outer wall of the second wellbore tubular and an inner wall of the first wellbore tubular;
• a pressure gauge coupled to the wellbore assembly to measure a pressure within the TTA;
• a pressure cable positioned within the TTA and coupled to the pressure gauge;
• a first connection at a first end of the wellbore assembly, the first connection attached to the first wellbore tubular and the second wellbore tubular, the first connection configured to couple the first end of the wellbore assembly to a wellbore tool;
• and
• a second connection at a second end of the wellbore assembly opposite the first end of the wellbore assembly, the second connection attached to the first wellbore tubular and the second wellbore tubular, the second connection configured to couple the second end of the wellbore assembly to a wellbore tool.
