1. The OFC is an OSR filtration control agent that effectively manages the filtration loss of oil-based drilling fluids, ensuring borehole stability and minimizing damage to the formation. It is a highly recommended filtration control agent for water-in-oil or oil-based drilling fluids, with a suggested dosage range of 10.5-14.0 ppb.
