Continuation of cooperation with PJSC "Ukrhazdobycha". Works were started simultaneously on two wells. Permits for drilling mud services were received on the electronic trading platform "Prozorro".
INFORMATION ABOUT THE WELL:
CASING POLICY OF THE WELL №182:
Casing Ø426 mm - 175 m;
Casing Ø324 mm - 2125 m;
Casing Ø245 mm - 2960 m;
Casing Ø178 mm - 3395 m;
Liner Ø139,7 mm - 3545-3940 m.
Drilling mud services will be provided within two intervals. Drilling of the first interval (2940-3395 m) will be carried out with the utilization of polymer-inhibited drilling mud PIBR-2 with a density of 1200 kg/m3. For drilling-in second interval 3395-3940 m where liner will be runned, polymer-inhibited mud will be changed to clayless biopolymer system with a density of 1120 kg/m3..
Well drilling term - 178 days. Temperature on depth 3940 m - 83оС.
CASING POLICY OF THE WELL №4:
Casing Ø426 mm - 250 m;
Casing Ø324 mm - 2260 m;
Liner Ø194 mm - 3330-4400 m;
Casing Ø140/168 mm - 5195 m.
Drilling mud services will be also provided within two intervals at this well. Polymer-inhibited drilling mud PIBR-2 with a density of 1340 kg/m3 will be used for drilling interval Ø194 mm. Clayless drilling mud Biokar-MT with a density of 1230 kg/m3 will be used for maximize the preservation of reservoir properties of production horizons.
Well drilling term - 223 days. Temperature on depth 5195 m - 112оС.
