comments: Performed reverse circulation exercise 50-100 lpm / 3.5 bar. Moved string down in 20 cm increments from 2662.8 m to 2664.3 m. Had 1 bar increase in pressure from 2663.4 m. Had overflow response on tubing while RIH at 2664.3 m before flow was cut off - indicating that the lower most seal had entered 7" liner PBR. Confirmed the situation by reverse circulating 50 lpm up to 8.6 bar with no returns. Stopped circulating. Measured 7.24 m stick-up. TOL found at 2662.85 m.
