In very difficult weather conditions we had to assemble and run the whipstock with hydraulic anchor on the well No.1013 Samburgskogo condensate field. Despite the 45-degree cold the hydraulic system HAS-7" for 7' casing was assembled and run to the depth of 3246m. The window cutting process was finished during 9 hrs. Wall thickness - 10.36 mm at a zenith angle of 33 degrees.

The technologists of DI choos the right BHA for window cutting to ensure the Schlumberger BHA for the drilling will pass through the window without any problems. Now it is drilling of a sidetrack.
