Application Of Emulsifier

Application of emulsifier is widely used for oil drilling fluids.

CPMUL-P serves as a primary emulsifier in oil-base mud systems. It is formulated to give good

emulsification, improved thermal stability of the invert emulsion, and enhanced high-temperature,

high-pressure (HTHP) filtration control. Through comprehensive tests in a number of oil-base mud

formulations with various base oils, mud densities, oil/water ratios and hot-rolling temperatures, it

proves that at working temperature up to 149^oC (300^oF), CPMUL-P can maintain high ES

(electrical stability), low HTHP filtrate and desired rheological property.

How To Use An Emulsifier

For test procedure of mud performance, please refer to ANNEX below.

ANNEX

Test Procedure of Mud Performance

1.  Test Reagents

White oil 5^#     low-aromatic-content mineral oil,

Organophilic clay CP-150 high-grade organoclay, made by Camp Shinning

Calcium hydroxide (lime)   analytical grade, from local market

CPmul-S   secondary emulsifier, made by Camp-Shinning

Barite     API grade, from local market

Rev Dust    evaluation clay, from the U.S. market

3.  Test Mud Preparation

• 25% CaCl₂preparation: Dissolve 25g anhydrous CaCl₂ into 75ml distilled water. Store it for service.
• Pour White oil5^# into the mixing cup of Hamilton Beach Mixer. While stirring on the mixer at low rpm, add CPmul-P and CPmul-S, and wait until they are fully dissolved in the oil. Then at 11000rpm stirring strength, add 25% CaCl₂ solution slowly into the oil. Then add other additives at the order of lime,Organophilic clay CP-150, Rev Dust and barite. When everything is added, continue to stir the mud at 11000rpm for 30 minutes.

4.  Mud Performance Test

• Warm the mud to 49^oC (120^oF). Test R600 (dial reading at 600rpm of Fann 35 VG Meter), R300, R200, R100, R6, R3, 10-seconds gel strength and 10-minutes gel strength. Calculate Yield Point

(YP):

YP= 2xR300 – R600 (lb/100ft²)

• Hot roll the test mud in a hot roller at 121^oC (250^oF) for 16 hours. After hot rolling, cool the mud to 49^oC (120^oF), then test R600, R300, R200, R100, R6, R3, 10-seconds gel strength and 10-minutes gel strength. Calculate Yield Point (YP):

YP= 2xR300 – R600 (lb/100ft²)

• Electric Stability (ES) is tested always at room temperature. ES is tested before and after hot rolling. Before testing ES, stir the mud at 6000rpm for 10 minutes on Hamilton Beach Mixer.
• HTHP filtrate is tested after hot rolling. Test is at 121^oC (250^oF) and 500psi pressure differential. Collect the filtrate for 30 minutes.

RECOMMENDED DOSAGE

We recommend a dosage of 2-4% (v/v) for normal application upto 150 ᵒC. Lab formulation trials are suggested before field application.
