Production & Wellsite Chemicals

Solid stick foaming agent for gas well deliquification. Reduces brine column surface tension from 70 mN/m to 25–35 mN/m, generating low-density foam (0.1–0.3 g/cm³) lifted by natural reservoir pressure. Typical production uplift: 15–40% gas flow restoration within 48 hours of first treatment.

Film-forming corrosion inhibitors for drilling and production environments. Protects against CO₂, H₂S, O₂, and chloride attack. Stable up to 90°C (194°F). Tolerant up to 250,000 ppm TDS. Reduces corrosion rate to <3 mpy at 200 ppm continuous treat in CO₂-saturated brine per ASTM G59 coupon testing.

Triazine-based liquid H2S scavenger for sour gas and crude oil streams. Irreversible chemical neutralisation eliminates H2S to pipeline specification and mitigates sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC). Stable to 90°C (194°F), tolerant to 250,000 ppm TDS.

Ground natural limestone or precipitated CaCO3, used as a weighting/bridging agent. Provides moderate density and fine bridging/fluid-loss control; critically, it is fully soluble in mild acid (HCl), so any filter cake or bridging solids it forms can be dissolved and removed on demand.

Surfactant blends, often ethoxylated block copolymers, dissolved in an aromatic or other solvent carrier. Migrate to the oil-water interface in produced crude oil emulsions, displacing natural emulsifying agents and allowing water droplets to coalesce and settle out.

Surfactant/polymeric additives designed to interact with asphaltene aggregates in crude oil. Adsorb onto asphaltene aggregates, sterically and electrostatically preventing them from flocculating and precipitating out of solution as pressure, temperature, or composition changes during production and transport.

Polymeric, pour-point-depressant-type additives. Co-crystallize with paraffin wax molecules as crude oil cools below its wax appearance temperature, disrupting formation of a rigid wax crystal lattice and keeping wax dispersed as small, non-adherent crystals.

An additive package built on boundary-lubrication chemistry - sometimes chlorinated/sulfurized paraffins, sometimes ester-based synthetics. Forms a durable lubricating film at metal-to-metal and metal-to-formation contact points under very high contact pressures found in directional and horizontal drilling.

An oxygen scavenger used to protect drill string and casing from oxygen-driven corrosion during WBM operations.

An alternative oxygen scavenger to ammonium bisulfite, available in both solid and liquid form.

Provides an alkalinity reserve in OBM, buffering against acid-gas (CO2/H2S) influx and activating certain emulsifier chemistries: a functionally different role than pH control in WBM.

Used to formulate the internal (dispersed) brine phase of invert-emulsion OBM/SBM systems, balancing water activity against the formation to prevent osmotic water transfer and shale destabilization: essential, non-substitutable invert-emulsion chemistry.

A bio-based synthetic ester lubricant offering extreme-pressure performance with a materially better biodegradability and environmental profile than mineral-oil or chlorinated-paraffin EP lubricants: named generically here to remove a competitor trademark reference.

A standard production-chemical treatment preventing calcium carbonate and barium sulfate scale deposition in producing-well tubing and pipelines.

Production treating chemical formulated to prevent and disperse asphaltene precipitation in crude oil production and transport systems. Stabilises asphaltene micelles in solution, reducing deposition risk in tubing, flowlines, and surface equipment.

Strong alkaline base used for pH control in water-based drilling fluids, and particularly suited to potassium-based systems where it supplies both alkalinity and potassium ions for shale inhibition.

Basic zinc carbonate used as an H2S scavenger in water-based drilling fluids. Reacts with soluble sulfide to precipitate insoluble zinc sulfide, reducing H2S-related corrosion and personnel exposure risk.
