Riteks RSP-4D is a powdered surfactant for use in cement spacers, chemical washes, and drilling fluids. This product provides water wetting tendencies to enhance the cleanout of oil substrates through an ultra-low interfacial tension, helps leave the pipe and formation in a water-wet condition, and is applicable over a wide temperature range.

We developed RSP-4D to improve the efficiencies in dosing and to allow a true ‘on-the-fly’ spacer or chemical wash system, in combination with Riteks MS Spacer. Riteks RSP-4D surfactant acts as a degreaser, provides water wetting properties, promotes cement bonding, and helps to assure rheological compatibility in between oil-based (OBM) or synthetic-based (SBM) muds and the spacer.

Features and Benefits

• Helps improve spacer performance when displacing oil-based mud systems
• Facilitates the removal of filter cake build-up while improving cement bonds
• Designed to reduce interfacial viscosity and preferentially water-wet the pipe and formation to promote better cement bonding
• Aids in the rheological compatibility between the wash/spacer and oil-based (OBM) or synthetic-based (SBM) muds
