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 casing Ø139,7 mm at depth of 4400 m at this well.
The invert emulsion drilling mud OBM Witer II will be used while drilling.
PARAMETERS OF OBM WITER IІ:
- Density – 1,20 g/сm3;
- Funnel Viscosity – 35-110 s;
- Gel – 30-60/40-150 dPa;
- PV – 30-80 cP;
- YP – 60-180 dPa;
- Filtration Loss – ≤3 ml/30 min;
- Electrostability – ≥250 V.
