Development and service of drilling fluid

Another well with a depth of 5935 m was successfully drilled together with an external drilling commissioned by JSC "Ukrgazvydobuvannya". The bottom hole temperature of 145 °C and the risks of gas shows with a possible increasing of mud density to 1.45 - 1.80 kg / m3 put restrictions on the use of biopolymer drilling mud Biocar-MT. Therefore, polymer chlorine-potassium drilling mud "P-HKR" was used for drilling-in of the productive horizons. The technological properties of this flushing fluid are completely corresponded to conditionals of the well.
Liner Ø127 mm was set to the bottomhole and successfully cemented. We hope for good results of well production testing.

PARAMETERS OF DRILLING FLUID P-HKR AT THE END OF DRILLING:
  • Density – 1260 kg/m3;

  • PV – 23 cP;
  • YP – 81 dPa;
  • Filter Loss – 5 ml/30 min;
  • KCl – 5 %;
  • рН – 8,1.
