Yes, sodium carboxymethyl cellulose (CMC) water retaining agent used in oil drilling mud usually comes in two types: high viscosity and low viscosity. These two types of CMC have different molecular structures and viscosity ranges and are suitable for different applications and needs.

High viscosity CMC is suitable for scenarios requiring higher viscosity and water retention properties. It can provide strong wettability and gelling effect, and is often used under conditions such as high temperature, high pressure, high solid content, and complex drilling.

Sodium carboxymethyl cellulose (CMC)

Low viscosity CMC is suitable for scenarios requiring lower viscosity and flow properties. It provides good moisture retention and has stable mud properties. It is generally suitable for general drilling operations and conditions.

When choosing to use high or low viscosity CMC water retaining agents, evaluation and selection need to be based on specific drilling conditions, target performance and operational needs.

Shandong Welldone CMC manufacturers usually provide CMC products with different viscosity grades to choose from. It is recommended to consult in advance when purchasing to provide you with the most suitable products and suggestions.
