Troubleshooting with low electrical stability (ES) in oil-based mud

 

These include singing show you that you have problems with the electrical stability.

1. Low electrical stability - If you see that ES is less than 700, you should really check your emulsion.

2. There is talk of barite sag. You can just check the weight of your mud on top of the pit and compare the weight of the mud at the bottom of the pit.

3. The drilling mud grainy and dull.

4. You'll see water in a filtrate of paper.

5. Shaker screens are plugged off.

 

Why this happens?

 

There are some issues in the mud emulsion damage as indicated below:

1. Not enough emulsifier

2. rush of water tank

3. Water leakage from the surface equipment in the mud system

4. Exhibits a high concentration of calcium chloride

5. Not enough time to shear of the fresh mud

 

How this is solved?

 

Following these treatments can help to solve this problem.

1. Add a higher concentration of emulsifier

2. Add more lime-oil and water mix well in a basic state. Lime acts as the media to create a good emulsion.

3. Take more time to shear the mud

4. Dilute with water and add emulsifier

5. Add soda to control the chloride content because more of chloride content in the mud, the more difficult to form a good emulsion.
