Riteks MS Spacer – Tunable Membrane Sealing Spacer

Riteks MS Spacer is a customizable spacer that is applicable in remedial, primary, and loss circulation situations. The system can help mitigate lost circulation issues while cementing by minimizing induced losses & filtrate invasion and damage. It offers dual functionality as a yield point (YP) modifying tunable spacer to effectively clean the hole. MS Spacer creates a low permeability membrane across the well’s formations that penetrate micro-fractures to mitigate cement leak off and increases the ability to place cement jobs. Features and Benefits

• Forms a seal to minimize filtrate invasion
• Effectively reduces cement losses and formation damage from filtrate migration
• Enhances hole cleaning prior to cement placement, effectively removing gelled drilling fluid
• Allows increased ECD at casing depth in wells where the fracture gradient limits design density of cement
• Provides wellbore strengthening and reduces induced losses
• Compatible with virtually all cement systems and drilling fluids

You can use MS Spacer, as a free-flowing power, in a dry-blended and easily dissolve it in the mixing water.

Riteks RSP-4D – Dry Surfactant Package

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
