C&A has developed a small scale laboratory pipe flow device to compare the performance of different friction reducers in water. The performance of the lab friction device has been correlated to literature data published by Shah and Kamel, SPE 118949 (2009).

The friction testing method is correlated to previously published work in larger diameter tubing and utilizes a small volume of water so that actual field water samples can be used. The friction reduction test has been used with great success to rate the performance of friction reducers in various types of water, to determine optimum friction reducer concentration, and to determine the interaction of other common additives such as biocides or scale inhibitors with the friction reducers.
