Absolutely flexible drilling mud system, individually designed for specific mining and geological drilling conditions. The principle of the stability of the wellbore — omnidirectional impact on each type of rock.
- Extended clay intervals and shale.
- Heat resistance up to 200°С.
- Primary and secondary (development) dissection of the reservoir.
- Ecologically safe.
NeoDirect (Oil) - 1st type emulsion systems
- Complements the main HP-WBM solution system NeoDirect.
- Designed to increase mechanical drilling speeds.
- High inhibitory properties.
- Excellent lubricating properties.
- Solution density from 0.9 g / cm3 (for the emulsion version).
- At high drilling speeds it prevents oily formation.
- Ideal for extended HS.
- "Customer's" liquid can be used as a hydrocarbon base
- 1. Direct emulsion.
- 2. 15-40% of the hydrocarbon phase
NeoDirect - how does it work?
- Primary Interaction with the internal structure of clays
- Surface Creation of microcool layer on well walls
- Blocking Creating a membrane screen
- Emulsion Hydrocarbon hydrophobization of the wellbore
Multifactorial effects and inhibition of clay rocks can achieve high rates of wellbore stability.

Components are selected individually for the necessary conditions of the well.
NeoDirect - inhibition and strength tests:
- Double decrease in bulk swelling of the clay sample.
- Even after 7 days, inhibition is better than 24 hours of the common KCL system.
- The core material of the Kynovsky horizon material (one of the main unstable intervals of the Volga-Urals) is used for the test.
- 150% higher tensile strength than KCL.
- Even in its pure form, without reducing filtration, the strength indicators remain high.
GX-LUBE - the greasing additive:
- Based on modified lubricating surfactants.
- High strength "oil" film.
- Strong adhesion on metal.
- Resistance to high salinity drilling fluids.
Direct emulsion
- Forms a dense emulsion in a filter cake.
- Facilitates the free movement of the drilling tool / casing along the wellbore.
- Improves chisel efficiency - increase mechanical drilling speed
- In terms of friction properties, NeoDirect (Oil) is approaching ERUO.
- Ideal for extended horizontal sections with high transport weights.
- Designed for high mechanical drilling speeds and intense spatial deviations of the profile.
NeoDirect® — high drilling rates
- 1. "Free" drilling in the "slide"
- 2. Reduced transport weights with open source software
- 3. High borehole cleaning coefficient
- 4. Excellent borehole stability
NeoDirect — high commercial drilling rates
Above are the achievable performance, they should be considered as a goal.
Calculated on the basis of long-term statistics, experience in the use of various systems of solutions and their impact on the construction of the well.
