Mixed retarder type blend

Description

A powder cement retarder that is typically used when the bottom hole circulating temperature is above 180 °F. Provides effective retardation of the cement slurry in casing, liner, squeeze and abandonment applications. Aubin® CR-112S has limited dispersing properties and is normally used in conjunction with dispersants, such as Aubin® CD-1B, Aubin® CD-4, Aubin® CD-6 or Aubin® CD-8.

Synthetic retarder

Description

A high temperature retarder used at bottom hole circulating temperatures up to 350 °F. Aubin® CR-130 is usually used at concentrations between 0.1 and 0.5 %bwoc. It is compatible with other cement additives including polymer-based fluid loss additives and dispersants. The effect of Aubin® CR-130 on thickening time varies considerably from one brand of cement to another. It is recommended that each system is laboratory tested when designing the slurry to be run in the field. Do not age in mixwater for prolonged periods of time at low pH with polyols, PVA and some other polymers. If considering powder blending into cement, we recommend closely related Aubin® CR-120SB.

Synthetic retarder

Description

A medium temperature cement retarder which can be used at 160 to 220 °F BHCT. Typically used at 0.1 to 2.0 %bwoc, dependent on temperature and slurry design. Soluble in mixwater; this product may degrade if stored in mixwater for excessive times, particularly in warm weather and with the presence of microbes in the water. If stored for prolongued times, it is recommended to prepare new mixwater or retest mixwater samples. Avoid excessive stacking pallets, if clumping is of concern.

Synthetic retarder

Description

A synthetic retarder formulated to be effective at bottom hole circulating temperatures below 93 °C (200 °F) Aubin® CR-400 is stable through its temperature range and is of low sensitivity to small changes in concentration. Advantageous when long liners are cemented, cement sets in acceptable time at cooler liner top temperatures. Aubin® CR-400 is normally used at concentrations between 0.1 and 1.0% BWOC: generally 0.5% will give around 4 hours thickening time at 90°C (194°F). The effect of Aubin® CR-400 on thickening time can vary from one brand of cement to another; it is recommended that each slurry is laboratory tested to finalise the design.

Improves mud removal and zonal isolation and prevents mud/slurry incompatibility problems. Can be applied in a wide range of fluid density, depending on weighting agent, typically 1.0 – 2.4 g/ml (8.6 – 20 lb/gal). Good fluid loss control properties, depending on final spacer composition. Stable up to 121 °C (250 °F). For thicker slurries, loading may be around 12 - 20 lb/bbl.

Mixed polymer blend

Description

A cement spacer additive typically used in weighted spacer designs at bottomhole temperatures below 150 °C. Cement spacer Aubin® CSP-600 is a powder that is normally mixed at the wellsite along with water and weighting agent to provide a finished spacer fluid with the required fluid density; a spacer surfactant (such as Aubin® CSS-04) is also normally used in such a system. Spacers made with Aubin® CSP-600 improve mud removal and zonal isolation, prevent mud/cement slurry incompatibility problems and afford good fluid loss control properties, with the correct final spacer composition. Allows for a wide range of fluid density (typically 8.4 to 20 lb/gal); due to the variation in drilling mud and cement slurry composition, compatibility testing should always be run in a laboratory prior to performing a cement operation.

Technology

Mixed surfactant and solvent blend

Description

A cement spacer surfactant that has been developed for use in spacer systems, in order to remove hydrocarbon films and residues left behind from aqueous and non-aqueous drilling fluids. Through this function, cement slurry contamination can be minimized, ensuring cementing performance is delivered as expected. Additionally, Aubin® CSS-04 will leave surfaces-water wet, therefore aiding cement bonding and preventing possible communication channels between zones. Aubin® CSS-04 is classified under the OCNS as Gold rated with no substitution warning. Application rates typically range from 0.5 – 3 gal/bbl of spacer in fresh water and brine systems, although this will be dependent on the specific drilling fluid for a given application.

Technology

Mixed metal salt blend

Description

A liquid, cement thixotropic additive, which allows slurries to become immobile quickly when they are removed from high shear flow conditions. Thixotropic slurries are used where there is likely to be excessive fallback of the cement column, or where losses into the formation are high. In combination with a suitable pumping schedule, the flow of the slurry is stopped for a few minutes, allowing the slurry to gel and become immobile. When pumping is recommenced the slurry is readily moved in the high-shear area in the annulus, but remains static in the lower-shear zone of the loss area. In this way, better fill-up is achieved, with reduced slurry loss. These properties may also be useful in grouting applications. Normal slurry density range is 13 to 15.5 lb/gal (1.56 to 1.86 kg/L). Aubin® CTX-15 is normally used at 0.4 to 1.0 gal/sk of cement (3.55 to 8.88 L per 100 kg cement).

Metal salt

Description

A thixotropic additive, which allows slurries to become immobile quickly when they are removed from high shear flow conditions. Designed to be used with Portland cement in primary cementing, lost circulation and squeeze applications, where the slurry is required to become immobile after placement. The use of calcium chloride increases the rate of gel strength development as well as accelerating the setting of the slurry. CTX-35R reacts with the C3A in the cement to provide thixotropy and a slight expansion of the cement when it sets. The reaction also results in the set cement being more resistant to attack by sulphate and chloride brines. Commonly used at 10 %bwoc, but can be used at various ratios to achieve the slurry properties required. Lost circulation materials can be added to the slurries to help control slurry loss into thief zones.
