Development and service of drilling fluid

The interval of first intermediated casing Ø340 mm was drilled in less than a month. Drilling was conducted without complications. The casing was running with one section and successfully cemented. Well construction is carried out by Croatian company Crosco. After drilling a cement and casing attachments, drilling fluid will be changed to a polymer-inhibited drilling mud PIDM.

PARAMETERS OF DRILLING MUD BEFOR CASING RUNNING:
  • Density – 1,18 g/сm3;
  • Funnel Viscosity – 50 sec;
  • Gel – 91/144 dPa;
  • PV – 13 cP;
  • YP – 125 dPa;
  • Filter Loss – 7,4 ml/30 min;
  • рН – 8,9.
