GEOSYNTHESIS ENGINEERING

Development and service of drilling fluid

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/mwill be used for maximize the preservation of reservoir properties of production horizons.
Well drilling term - 223 days. Temperature on depth 5195 m - 112оС.
