The workover operation of this well with using of BIOCAR-Block was performed at the last year. The workover was successful and the well brought into operation with high production rate.
However, the tubing within the interval 3925-3940 m was left in the well in 2016. It will be removed from the well during this workover operation.
The reservoirs are with abnormally low formation pressure and severely depleted. Take into account this factors, a special killing fluid BIOCAR-Block was developed. It prevents fluid loss during workover and protects pay zone from pollution.
PARAMETERS OF THE KILLING FLUID "BIOCAR-BLOCK" :
- density – 1,12 g/сm3;
- funnel viscosity – 53 sek;
- GEL – 53/72 dPa;
- PV – 18 cP;
- YP – 144 dPa;
- Filter Loss – 4,5 сm3/30 min;
- рН – 7,22.
