Development and service of drilling fluid


«Mente et malleo»

Two sections of casing will be running .
First section was run in the interval 3797-5487 m. Drilling of the interval was conducted with the utilization of clay less drilling mud Biocar-МТ.

The workover operation of this well was performed for the milling the old part of the tubing, which is remained during the previous workover.  

Directional well with vertical inclination of 125 m. Design depth of well 4620 m. Pay zone of this well will be opened with using of invert-emulsion drilling fluid "Witer-II".

Trouble-free first section casing running and setting

The liner was run in two sections.
The first section was run in the interval of 4596-4871 m and set with the help of swelling packers. Drilling of the interval was carried out using an invert-emulsion mud Witer II.

The first intermediate casing was run in one section to the depth of 2187 m.
