comments: M/U TDS sub and positioned string at 804 m. Lined up to cement unit and confirmed line-up.

Attempted to pressure test annulus cement and EZSV plug to 115 bar / 10 min. Pressure had decreasing trend due to possible air in the system.

Attempted to pressure up well 6 times. Less pressure drop observed for each attempt.
Pressure tested annulus cement and EZSV plug to 115 bar / 10 min, bled off pressure.

Meanwhile: B/O pup joints previously used for space out.
