White Paper: BYK Additives Bringing Solutions to the Surface

BYK-GO 8730, a new liquid and easy-to-handle additive, allows the control of the rheological behavior in low-polarity liquids such as mineral and synthetic oils. BYK-GO 8730 effectively prevents the sedimentation of various particles such as guar gum, xanthan gum, or friction reducers. In addition, storage-stable suspensions of these particles can be prepared, transported, and used on site without sedimentation issues.

BYK-GO 8730 is a polyurea-based rheology additive that can effectively prevent sedimentation without severely impacting viscosity in liquid oil formulations. For oilfield applications, like guar or friction reducer slurries, a typical dosage is 1 to 2% delivery form in total. The additive can be mixed into the base oil and the powder added afterwards, then mixed until homogeneous.

Compared to existing solutions, BYK-GO 8730 does not require a special activation process and is a particle-free liquid. Easy incorporation and fast processing are further benefits over established technologies. Another advantage is the organic polymeric nature of the rheology additive. There are no inorganic particles involved which always have the danger of blocking pores in the formation. This makes it very useful for all stimulation applications where this requirement is highly appreciated.

This white paper describes the chemistry and functionality of BYK-GO 8730 and how it helps to stabilize oil-based suspensions using a “particle-free” working mechanism. General handling guidelines and application examples are provided. Viscoelastic properties of the application system and how they are affected by the additive are also discussed.
