ORGANOCLAY – WEGO 190
|
Wego 190 is an organoclay (tetraallkyl ammonium bentonite) for oil- based drilling mud (fluid). |
1. Advantages:
|
o Good suspension, thixotropy and stability in crude oil, diesel oil systems. |
|
o Easy of incorporation. No need for polar activator or making pregel. |
|
o Furnish the drilling mud(fluid) with good suspension, wall-protection and antifiltration properties. |
|
o Maintain stable physical performance under the pressure of 10″ at the temperature of 230oC. |
