Aubin®
Aubin® is Italmatch Chemicals’ Energy product line, offering a wide portfolio of innovative specialty additives for well services, cementing and pipeline operations, supporting oil & gas well construction, stimulation and well integrity applications worldwide.
Aubin® Acidizing Solutions
Acidizing solutions comprise Italmatch’s chemicals for well stimulation and cleanup. The portfolio includes corrosion inhibitors, specialty surfactants, viscosifiers and gel treatments tailored for acid jobs. These additives protect metal equipment, enhance acid-rock reaction and carry proppant or debris in acid fracturing and matrix acidizing treatments.
Features:
- Acid corrosion inhibitors (for HCl/HF environments);
- surface-active agents (wetting agents, emulsifiers);
- viscoelastic and polymer gel systems;
- acid breakers and non-emulsifiers;
- clay stabilizers and surfactant wettability modifiers.
Applications:
- Carbonate/sandstone acid fracturing;
- matrix acidizing of wells;
- acid washes and mud cake removal;
- well stimulation in mature or tight formations.
Aubin® AXI-Zone
Aubin® AXI-Zone is a two-component zonal isolation gel used for temporary, pressure-retaining plugs. The base fluid and adjustable retarder are mixed and pumped into the well; under reservoir conditions they set into a rigid, impermeable gel. This single-phase plug holds pressure for operations like valve swaps or repairs. AXI-Zone can be broken down with an acid-based breaker when no longer needed.
Features:
- Two-part pumpable gel (base + retarder);
- forms a rigid, pressure-tight plug;
- works up to ~350 °F and in high-salinity conditions;
- set-time tunable by retarder dosage;
- non-damaging to formation and easily removed with weak acid.
Applications:
- Temporary zonal isolation during interventions;
- pressure control for wellhead maintenance or equipment replacement;
- pressure testing of well sections;
- plugging flows during completion changes;
- emergency shut-off during workover
Aubin® Pipeline Technologies
Pipeline technologies cover innovative pigging and chemical cleaning solutions for pipeline maintenance. EVO-Pig elastomeric pigs flex through complex, varying-diameter lines to sweep debris and displace fluids even without special pig launchers. Specialty pipeline gels capture loose solids or hydrocarbons: debris pick-up gels lift sand to the pipe center, separator gels clear remaining oil before seawater flush. Complementary chemicals (dewatering agents, surfactants, scale dissolvers) ensure pipelines are clean and flow-assured.
Features:
- Shape-memory EVO-Pigs (compressible solid pigs for tight bends);
- debris-collection and separator gel formulations;
- pipeline-rated surfactants and foamers;
- hydrate/wax solvent packages;
- hydrotesting additives.
Applications:
- Pipeline cleaning and de-oiling (gathering lines, flowlines);
- pre-commissioning and regular pigging;
- removal of sand and debris;
- hydrostatic testing and drying;
- integrity pigging before inspection;
- final pipeline decommissioning
Aubin® Resolv 260
AUBIN® Resolv 260 is a low-viscosity, pumpable fluid for temporary well plugging. Upon placement under reservoir pressure, it reacts to form a compliant solid gel plug. This gel expands under prressure, to fill cracks and leaks in cement plugs or annuli, effectively sealing unwanted leak paths. The plug can later be dissolved with breakers, allowing safe coiled-tubing workovers or removal of tubing.
Features:
- Low-viscosity 3-part gel system;
- pumps easily through small tubing (minimum friction);
- converts to a flexible gel under downhole conditions;
- seals around irregularities (cracks, micro-annuli);
- gel plug is easily broken down by mild acids.
Applications:
- Temporary seal of leaking cement plugs or well leaks;
- remediation of sustained casing pressure (gas or fluid leaks);
- isolating leak pathways during workovers;
- provides a base for cement plugs;
- emergency containment in P&A operations
Aubin® Wellbore Cleanup
Wellbore cleanup products are biodegradable surfactants and solvent mixtures that remove drilling fluids and solids. They dissolve oil-based and water-based mud residues and filter cakes, rendering the wellbore surfaces water-wet. These straightforward fluids (often mixed into fresh or seawater) aid in preparing the well for cementing or production without harming downhole equipment.
Features:
- Biodegradable surfactants and chelators;
- dissolves oil and water-based mud filter cakes;
- compatible with common polymers/additives;
- solvent-free (safe for seals/packers);
- single-phase liquids for easy mixing and pumping.
Applications:
- Post-drilling wellbore cleaning;
- annular and perforation cleanup before cementing;
- removal of mud solids prior to completions;
- cleaning after stimulation;
- maintenance cleaning to optimize productivity.
Aubin® Xclude
Xclude is a revolutionary reservoir barrier technology for permanent well plugging. It uses a calibrated chemical reaction to precipitate minerals (e.g. calcium carbonate) deep in the formation, creating an impermeable plug in the reservoir pores. This rigless solution applies through tubing or coiled tubing, forming a durable scale barrier behind the casing without heavy cementing operations.
Features:
- In-situ mineral barrier formation;
- permanent inorganic scale barrier in the reservoir;
- applied through tubing (rigless deployment);
- environmentally safe, low-toxicity reactants;
- targets pore throats to block flow;
- Preserves inside tubing;
- Can be used alongside or as a substitute for cement
- Reduced carbon footpriint when compared to cement.
Applications:
- Well plug-and-abandonment (P&A) of depleted oil & gas wells;
- permanent zonal isolation for decommissioning;
- sealing abandoned reservoirs;
- augmenting or replacing cement plugs;
- bottom-hole isolation behind casing
Aubin® Xmax
Xmax is a patented chemical system for permanent water shut-off in wells. It operates by inducing insoluble mineral precipitation in the reservoir at selected zones. Deployed with standard coiled tubing or pumping, Aubin® Xmax forms an impermeable barrier that permanently blocks water-producing formations. This rigless treatment is safe, cost-effective, and integrates with routine well interventions.
Features:
- Forms deep in-situ mineral seal (permanent);
- designed for zonal water shut-off;
- no additional equipment or rig needed (coiled tubing or bullheading);
- safe, eco-friendly formulations;
- enhances hydrocarbon productivity by blocking unwanted water channels
- Reduced carbon footpriint when compared to cement.
Applications:
- Zonal isolation of water-producing intervals;
- controlling coning or channeling in mature wells;
- water shut-off after fracturing;
- preventing aquifer breakthrough;
- selected plugging in production or injection wells.
