Drilling fluids
Our contribution to drilling safety
Our goal is to ensure safety and quality at every stage of production. Petro-Unit strives to achieve high standards in the field of safety and environmental protection. Drilling fluid systems are individually selected for the geological and technological features of the well construction process and are tested in our stationary laboratory.
Below is a line of proven formulations for various areas of application and geological complications. With the advent of new technologies and solutions, we are constantly optimizing the formulations to meet the needs of our customers.

Drilling fluids
A formulation with pronounced inhibiting properties. Effective for drilling clay intervals with a high degree of hydration, swelling, and formation of bit balling on the BHA elements. Provides the maximum level of inhibition of a water-based drilling fluid. The formulation can be optimized for different levels of hydration and swelling of clay samples.
Used for drilling deviated and horizontal wells. Provides minimum friction coefficient comparable to oil-based mud.
It is used for drilling through massive salt intervals with intensive brine influx at high magnesium content. Stabilizes filtration rate at high temperatures (over 150 °C).
Safe for productive formation, stabilizes unstable shale formation, prevents cavings, minimizes filtration into the formation. Provides good hole cleaning while drilling deviated and horizontal sections of the well.
Drilling fluid is designed for drilling through productive formation with a density of up to 1.57 sg. The formulation is based on potassium formate, providing a minimum content of the solid phase in the fluid, a reduced friction coefficient, and high inhibiting properties.
Mud formulation with using of stabilizing additives for drilling intervals with high bottomhole temperature up to 200°C. May be used for weighted muds with a density up to 2.0 sg.
Mud formulation includes highly effective aerating additives for creating density in the range from 0.74 to 0.9 sg. This system is designed for drilling through reservoir with low formation pressure and reducing risk of downhole losses.
Inverse emulsion drilling fluid based on synthetic oil providing optimum parameters that meet the highest requirements in the field of oil-based muds.
A range of technological fluids based on various salts for different geological conditions in the density range from 1.18 to 2.35 sg. Can be offered as packer fluids with a high degree of corrosion inhibition.
Certification and compliance with standards
Our drilling fluids are certified according to ISO 9001:2015 quality standards, which confirms their high quality and compliance with international requirements.
