Riteks RCR-200 – Drilling Fluid Deflocculant / Dispersant

Riteks RCR-200 is an environmentally friendly deflocculant / dispersant that is used to control thermal gelation while stabilizing rheological properties in water based fluids. It is effective over broad pH ranges and mud types and particularly efficient in lowering PV's in high temperature, high density fluids with bottom-hole circulating temperatures (BHCTs) up to 220°F (104.4°C) and can withstand static temperatures up to 260°F (126.7°C). RCR-200 is particularly useful in cements containing high gel percentages, and increased concentrations of RCR-200 enhance the predictability of cement thickening times. Features and Benefits

• Increased concentrations of RCR-200 enhance the predictability of cement thickening times
• Improved slurry displacement rates at steady pressures
• Provides early cement-strength development
• Aid in extending a slurry's temperature range and yield a smoother, more uniform slurry
• Decreases the danger of over-retarded slurries at the top of a long cement column
• Helps displace slurries at high rates while maintaining formation pressure

Riteks CSE-6 – High-Quality Pozzolanic Additive for Cement

Riteks CSE-6 is high-reactivity metakaolin pozzolan produced by thermal activation of high purity kaolin clay within a specific temperature range that meets or exceeds all of the specifications of ASTM C-618 Class N pozzolans.  Riteks CSE-6 reacts with free lime produced during hydration of cement and produces additional cementitious material. Unlike other pozzolanic materials, CSE-6 was developed to maintain high reactivity, ultrafine particle size distribution and product consistency.

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

Riteks RFL-9 is a dispersing and retarding fluid loss additive for all API classes of cement. Riteks RFL-9 is an effective fluid loss additive in primary, remedial, and squeeze cementing, and can be used in bottom hole circulating temperatures (BHCT’s) between 60° and 300°F (15.5°and 149°C). Features and Benefits

• Useful in primary and remedial cementing applications
• Can lower equivalent circulating density due to its dispersing nature
• Lengthens total thickening time
• Helps to promote bonding
• Can be blended in dry cement or pre-hydrated in the mix water
• Can alleviate horsepower requirements of surface equipment
• Works well in water sensitive formations
• Works well with most suspension and viscosifying products

Riteks RCR-800 – Non-Lignin Cement Retarder

Riteks RCR-800 is a non-lignin cement retarder capable of retarding cement at temperatures between 80 - 220°F (20 - 105°C). This material is non-dispersing and is compatible in a wide range of additive combinations in API cements. This is an alternative to commonly used lignin retarders. It provides good strength development and can be used in a variety of situations such a water-extended slurries, long cement columns, or cooler temperatures. Predictable responses to changes in concentration and repeatable results has been shown. It has been proven effective in several API classes cements including Class G, Class H, Class A, Class C. Features and Benefits

• Non-dispersing properties
• Provides linear and consistent results and good strength development
• Very compatible with other cement additives
• Increases cement thickening time

Riteks RFL-70X – Powdered Latex Fluid Loss Additive

RFL-70X is a cementing additive that controls flow and fluid loss properties at bottom-hole circulating temperatures up to 210°F (99°C). Typical loading levels of up to 1 percent is normally sufficient at temperatures between 75°F and 200°F (24°C to 93°C) to help reduce fluid loss to 50cc. At temperatures up to 350°F (177°C), this additive can also provide free water control, chemical resistance, shear bonding properties, and thermal shock reduction. Features and Benefits

• Provides a slight increase to cement viscosity and gel strength, which helps reduce free water, settling, and sedimentation
• Helps prevent fluid loss and gas migration in most API and lightweight commercial cements
• Little to no effect exhibited on low temperature cement retardation
• Improved bonding can be achieved with low loadings
• Provides improvements to cement with enhancing durability, as well as improves bond strength and sheer bond strength for the life of the well
• Consequently, shear bonds have an increased resistance to thermal cycling
• Improvement to cement flexural strength
• Cement slurries containing RFL-70X are more resistant to acids and brines

Riteks THIX-C2 – Thixotropic Additive
