The 23" drill bit was pulled out of the hole around 4 o?clock last night after reaching TD for this drilling stage at 796 m.

TD for this drilling stage was reached yesterday around noon at the depth of 796 m. Drilling had been progressing with an average ROP of 3.5 m/hr without circulation losses. Inclination measurements at the bottom of the well showed the well inclining by 1.5°. The well was rinsed for approximately 4.5 hours before the drillers began pulling the drill string out of the borehole. The drill bit had been drilling for 42 hours, completing 341664 revolutions, and turned out to be in a good condition with a diameter of 23". Geophysical logging commenced around half past 4 last night with temperature logging. Pre-arrangements for casing the well with the 18 5/8" second intermediate casing string are ongoing.
