During TOOH operations, the mud seen flowing from the wellbore is known as trip flowback or annular flowback. This occurs due to the piston effect: as the drill string is pulled out, it displaces mud in the annulus, causing it to flow back to the surface. In this case, the flow appears consistent and steady, indicating effective well control and proper annular fill.

This flowback is essential to monitor, as it helps verify:
-Hole is not taking losses
-Well remains overbalanced
-No signs of influx (kick)

The mud properties (viscosity, density, and solids content) look relatively typical, with no signs of gas cutting or contamination, which is a good indicator of stable well conditions.
