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.
PARAMETERS OF IEDM WITER IІ:
- Density – 1,20 г/см3;
- Funnel Viscosity – 35-110 с;
- Gel – 30-60/40-150 дПа;
- PV – 30-80 мПа*с;
- YP – 60-180 дПа;
- Filtration (7 bar, oil filtrate) – ≤3 ml/30 min;
- Electrostability – ≥250 V.
