comments: Pressured up to 35 bar using cement unit - mismatch pumped vs theoretical volume. Suspected pressuring up against GT plug. Opened B-annulus valves to vent underneath plug and pressure dropped immediatly. Leakage observed across test plug despite steady pressure 35 bar indicating that plug did not vent into pipe when doing pressure test. Discussed situation - decided to re-attempt test while keeping B-annulus valves open.

comments: Increased pumprate to 50 lpm and put 100 bar differential across plug, leakage decreased and pressure curve indicated that plug was sealing. Achieved steady pressure curve at 100 bar. Bled off pressure to 35 bar and held test for 5 mins (1,7 bar drop / 5 min). Steady fluid returns observed from B-annulus. Pressured up to 345 bar and tested connectors + inner A annulus valve for 10 min - 1,3 bar drop - ok. Shifted valves on A annulus. Held pressure and pressure tested outer A annulus valve for 10 min - 0,7 bar drop - ok. Pumped and bled back 43 liter (35=>345 bar). Still minor fluid returns from B-annulus outlet but gradually decreasing.

comments: POOH with 5 1/2" DP stand and test plug. Observed dirt/mud residues plug. Found pieces of steel in the mud residues. Strapped pipe and found landing point 20,45 m vs theoretical 20,81 m - but likely that plug landed too shallow.
