comments: Set down to 87 m MT in block. Made 3 attempts to shear sleeve for closing ball vavle (3/4, 1,5 and 2 lefthand turns)- nogo. On 4th attempt the shear sleeve sheared out just after 2 turn and 3100 Nm applied torque. Pressured up to 30 bar on string above plug. Rotated string righthand to re-open ball valve and observed pressure dropping to 16 bar.
