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).

Technology

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.

Technology

Non-ionic surfactant blend

Description

Aubin® CW-20 wellbore cleaner is normally used during drilling displacement operations, where it dissolves hydrocarbon fractions of both water- and oil-based mud residues, providing excellent mud removal and water wetting. For this reason, Aubin® CW-20 is used as pre-treatment for cementing operations, as it improves bonding to casing and formation. Aubin® CW-20 can also be used as a pre-flush ahead of a weighted spacer, as well as for pit cleaning and rig washing. Application rates as a casing cleaner are typically 5-20 % v/v in fresh water, seawater or brine.

Scales and clays may aggregate downhole in operations with all types of mud and are a common factor in stuck pipe during drilling operations. Aubin® CW-30 can be used following both water and oil-based mud applications, with some solvency properties for both types of mud, with the mechanism of action targetting scales and clays collected during drilling. For pipe release applications, Aubin® CW-30 is used neat and adequate volumes should be used to ensure complete break-down of filter cake.

Technology

Glycol-based polymer

Description

A cement antifoam used in the temperature range 80 – 300 °F. Certain materials used to modify the properties of cement slurries are known to cause foaming or air entrainment, or both. The resulting inaccuracies in slurry density measurements may cause the operator to reduce the water content in order to raise the surface density to the specified value. A severely reduced pumping time may be the end result, especially if retarders and other additives are premixed in the water. Aubin® DF-4 is used to help prevent foaming and air entrainment caused by additives such as retarders, fluid loss agents, and salt. No effect on cement properties has been found with Aubin® DF-4, and it is compatible with all API classes of cement and all additives including accelerators, retarders fluid loss additives, dispersants etc. Normal dosages of 0.02 to 0.05 gps, depending on the slurry design and slurry mixing method.

Elastomeric pig suited for use where mechanical pigs cannot be transmitted, offering a way to treat scaled, corroded, telescopic, or otherwise restricted pipelines across a variety of applications. Used alone or in conjunction with gels and associated chemical products to maintain pipelines that would otherwise be considered "unpiggable". Can be used for most standard pigging applications except for 'scraping', given the physical nature of the pig. Able to be compressed without alteration of its physical properties, and regains and retains its original shape after compression and navigation of geometric pipeline changes, readily negotiating short-radius bends. For effective pig transfer and use, storage temperature should not exceed 30 °C.

Technology

Natural polymer gellant

Description

A chemically modified cellulose derivative used as a gelling agent for water, brine and acid solutions. Aubin® FWG-15 is recommended for use in reservoirs which are responsive to water-based stimulation fluids. It is well suited for medium to high temperature reservoirs where high viscosities are not required and natural polymers would break down. Due to its’ residue-free nature, Aubin® FWG-15 is ideal for use in waterflood injection wells and gravel packing applications. Provides greater viscosity per kg and retains higher viscosities at elevated temperatures than natural polymers. Provides 60 - 70 % friction reduction as compared to water. Excellent fluid loss control can be obtained through the use of fluid loss additives or a 5% hydrocarbon phase. Compatible with CO2 and N2 where the inclusion of such a gas is desired to aid in recovery of the well. Can be used in KCl, CaCl2 or other oilfield brines for protection of water-sensitive clays. Unlike many other gelling agents and crosslinked fracturing fluids, Aubin® FWG-15 is not sensitive to high brine concentrations.

Description

A monoethylene glycol (MEG)-based pipeline gel - a mixture of MEG viscosified using a special blend of natural polymers - primarily used for the prevention of seawater ingress into spools during commissioning, but also suitable for dewatering/deoiling pipelines and for cleaning gas lines where concerns about hydrate formation prevent the use of aqueous products. As with all pipeline gels, it must be pushed with liquid rather than gas; if gas is the only available medium, a pig must be used at the back of the gel.

Technology

3-part system comprising high density base, dispersable gelling agent and agelation accelerating agent.

Description

Low viscosity, easy-to-mix pumpable fluid used as a temporary plug for workovers (e.g., wellhead repair), as a base for cement plugs, and for remediation of Sustained Casing Pressure leaks or other wellbore/annulus leaks. The fluid's low initial viscosity allows it to be pumped through narrow-bore well intervention equipment with minimal friction and pressure drop; over time it reacts to form a compliant, solid gel plug that seals like a gasket under hydrostatic pressure. The plug can be removed using a chemical breaker when required (e.g., prior to well decommissioning).
