DrisPac SL (Superlo)

Other Names: Polyanionic Cellulose (PAC-SL)
Basic Properties: Filtration Control, Viscosity Stabilizer, Fluid Loss Reducer
DrisPac SL is a polyanionic cellulose (PAC) additive used in drilling fluids to control filtration, reduce fluid loss, and maintain viscosity stability. It is particularly effective in water-based mud systems, where preventing excessive filtrate invasion is critical.
As a fluid loss reducer, DrisPac SL forms a thin, low-permeability filter cake on the wellbore walls, minimizing the loss of drilling fluids into permeable formations. This action enhances formation stability and prevents wellbore collapse.
Additionally, DrisPac SL helps stabilize viscosity, ensuring that the drilling fluid maintains optimal rheological properties throughout the operation. This makes it an essential additive for extended-reach and high-angle wells where fluid performance is critical.
pH: DrisPac SL functions within a pH range of 7.0 to 9.0, making it suitable for most water-based drilling fluid formulations.
By incorporating DrisPac SL into drilling operations, operators can enhance filtration control, reduce fluid loss, improve viscosity stability, and protect wellbore integrity, leading to more efficient drilling performance.
