Which is NOT a step in the hard shut-in procedures while tripping?

The hard shut-in procedure during tripping operations is critical for maintaining well control and involves a series of specific steps designed to secure the well effectively in emergency situations. Among the options provided, the most appropriate action that is not part of the hard shut-in procedures is the opening of the BOP side outlet hydraulic valve.

The primary goal of a hard shut-in is to tightly seal the well and prevent any hydrocarbons or fluids from escaping. This typically involves actions like stabbing a full opening safety valve to secure the wellbore and close off any potential flow. Closing the safety valve is also crucial to ensure that the well remains isolated. Additionally, recording pressures is an important step in monitoring the well's status and ensuring that accurate data is obtained for further decision-making.

Opening the BOP side outlet hydraulic valve, however, does not contribute to securing the well in the context of a hard shut-in. This step could inadvertently allow fluid movement or pressure changes that defeat the purpose of fully isolating the well. Therefore, understanding the intended sequence and objectives of hard shut-in procedures clarifies why this option is not aligned with the necessary actions during such critical moments in drilling operations.
