Borregaard’s BioDrill® RC product family includes a wide range of speciality cement retarders and dispersants.

BioDrill RC200 and RC300 series

Variation in well conditions dictates the need for specialised retarders to fulfil proper zonal isolation requirements. Our BioDrill RC additives are used to retard cement, extend pump times, and allow the cement to set at the desired location in the production string over a broad spectrum of cements and drilling temperatures.

Besides, several BioDrill retarders provide a valuable dual function. In addition to functioning as a retarder, some also perform well as cement dispersants.

The BioDrill® RC200 series of products is primarily designed for low to moderate circulating temperatures in the range of 125°F to 206°F [52°C to 97°C].
BioDrill RC202 is also valued as an effective dispersant.


The BioDrill RC300 series of retarders is designed for mid-range, moderate circulating temperatures in the region of 125°F to 206°F [52°C to 97°C]. 
BioDrill RC301 and BioDrill RC303 are effective dispersants that can lessen the gelling effects of cements. They also dissolve more readily in brine and seawater.
