Development and service of drilling fluid


«Mente et malleo»

Inauguration of the teaching-research laboratory of drilling fluid created with the participation of DTEK and "Geosynthesis Engineering" company was held in Poltava University named after Y. Kondratyuk.

The well with the depth of 5700 m was drilled using pitless drilling technology. Clayless drilling mud Biocar® was used for penetration in the production zone. 

Killing of the well with abnormally low formation pressures was conducted with using  invert emulsion drilling mud Witer II, which recommended itself good on previous wells.

Design depth of well 5250 m. Pay zone of this well will be opened with using of invert-emulsion drilling fluid "Witer-II".

The next group of students came to “Geosynthesis Engineering” company for industry focused practical training.

Visean production deposits were cased in the interval 4110-5628 m.
Drilling in interval was performed with utilization of clayless drilling mud system Biocar MT®.
