Development and service of drilling fluid

The advantage of oil-based drilling fluids over traditional water systems has been repeatedly proven during drilling-in of productive layers in Ukraine. OBM Witer II will be used for drilling the productive horizons within the interval 5110 – 5450 m. The density of drilling mud is 1250 kg/m3. The required amount of OBM Witer II is provided to the customer on lease.

Water based fluid will be changed for oil-based drilling mud Witer II  after setting of the production casing Ø178 mm.
