The well is inclined, with an S-shaped profile. The angle set interval starts in the Jurassic deposit zone at a depth of 1000 m. The design drilling depth is 5477/5549 m.
DTEK Naftogaz continues a major program for restore and deepen the wells of the old fund by drilling sidetracks. It is planned to be drilled a sidetrack from a depth of 4400 m at this well.
The wellkilling was done by a special blocking fluid based on starch-bischofite gel (KBG).
The well has a horizontal section in the area of productive formations, target depth – 5245/6053 m.This well should reveal the productive interval represented by fractured carbonate deposits for the first time at the field. This approach should significantly increase the drainage area and provide high productivity.
We present to your attention a speech by Ph.D. Yu.V. Luban, Deputy Director of of LLC "Geosynthesis Engineering", at the VIII International Industry Forum on the topic "Жидкости для восстановления скважин старого фонда методом ЗБС в малых диаметрах".
Drilling a sidehole is planning for conducting well-workover operation. The Witer II invert emulsion flushing fluid will be used for drilling withing an interval of 4000 – 5509 m. Density of oil-based drilling mud will be 1200 kg/m3.
The well is vertically-orientated. OBM Witer II will be used for drilling the productive horizons.
Presence of oil in Pereddobrudzhinsky deflection was proven back in the Soviet times. After the collapse of the Soviet Union, there have been numerous attempts to develop this perspective region. Several wells were drilled with further production from them. However, stable productivity was not achieved...
