Dear Mr. Demirdal,
Drilling mud is important in the petroleum industry. Drilling mud can be composed of various types of clay. All the clays have their unique properties and when prepared with water, they will exhibit different viscosity, gel strength, and most importantly, the rheological characteristic of the drilling mud. We are required to observe the difference between Bentonite, and Attapulgite clay in both salt water and fresh water. It was also required to differentiate the few non-Newtonian fluid models, and determine the model associated with Bentonite, and Xanthan Gum. It is clear that Bentonite and Attapulgite give different characteristic to the drilling mud. Bentonite has a low yield of clay and it is highly ineffective in salt water. Attapulgite have a high yield of clay and it does not shown any significant signs of swelling. Bentonite encountered severe swelling when mixed with fresh water. Overall, Attapulgite would be a better choice when making drilling mud. Bentonite with fresh water exhibits Bingham Plastic properties while the Xanthan Gum with fresh water showed a fluid with a Power Law model.
I hope these observations will be of good use to you.
Thank you for your time
Sincerely,
