Description

 SHALE-X® is a water soluble organic material based on methyltrimethoxysilane. Designed to suppress shales and clays hydration process – both cuttings and wellbore wall.

SHALE-X® forms a protective water repellent complex on the clay particles, prevents water in- vasion into the shale matrix. Prevents clay wetting, dispersion and swelling.

Low-gravity solids build-up is 3-4 times lower compared to the conventional KCl/Polymer mud. Density as well as rheological properties remain stable for extended drilling period, even when PDC bits are used.

Field cases show: 2300 m open hole sections were drilled in shale formation with MBT=28 kg/m3 in the end of the section. Not a single m3 of mud was dumped.

Applications/Functions

 ·           extraordinary shale inhibition at minimal product concentration

·       minimum solids build-up

 ·       outstanding wellbore stability

 ·       stable density and rheological properties

 ·       easy circulation break without pressure surge

Advantages

 ·       minimum mud dilution and mud volume needed

·       thins mud rapidly at higher concentration – easy to use prior to cementing

·       adds 20-30C to polymer temperature stability

Recommended treatment

 2-3 kg/m3 (5-8 ppb). Can be added directly into the pit or through the mud hopper. Pilot testing is recommended.

Typical properties

 Dark brown to black liquid

 Handling

 Please refer to the MSDS for specific instructions

 Packaging

 SHALE-X® is packaged in 200l drums
