The well that has been spud today is unique for two reasons.
Firstly, this is the jubilee 100th well in our chronological list.
Secondly, at this well, we are planning to revive the technology of penetrating Jurassic and Triassic colloidal clays with OBM.

The exploration well, where we are starting our activity together with the Ukrainian-Belarusian company Service Oil, was drilled in 2014 in a frontier part of the field. According to the test results, it turned out to be far from being successful. Its productivity was low, and various methods of intensification proved themselves to be ineffective....

Another well has been successfully drilled at Semyrenky field. Despite the fact that DTEK Oil&Gas annually puts in the service a number of new wells, this event is, actually, extraordinary.

Vertical well with AHFP, design depth is 6300 m. Pit-less technology is used during drilling. OBM Witer-II will be used while drilling-in productive layers. 

We present to your attention the speech of Ph.D. I.P. Gafich, the Director of Exploration and Prospective Development of DTEK OIL&GAS at the V Kiev Conference: "До проблеми нарощування видобутку газу в Україні. Можливі напрямки і їх ресурсне обґрунтування, основні завдання реалізації (погляд ДТЕК Нафтогаз)".

Inverted oil-emulsion cement slurry was designed for cementing casing strings and installing cement plugs in the intervals that were drilled using oil-based drilling fluids (OBM). Inverted oil-emulsion cement slurry is an invert emulsion, whose external phase is a hydrocarbon liquid. The formation of cement stone at all stages of hardening of an oil-emulsion cement slurry in a well occurs without changing the kind of emulsion and inverting its phases.

DTEK Oil&Gas completed drilling of well No. 59 with a depth of 5,245 m at the Machukhske gas condensate field.
