Oilfield Corrosion Inhibitor Series | Beta Pramesti Asia
Oilfield corrosion inhibitor for water and gas production systems, with field-adjusted injection from wells and pipelines to process equipment in Indonesia.
An oilfield corrosion inhibitor reduces metal loss and pitting by forming a protective film on surfaces exposed to corrosive production fluids. PT Beta Pramesti Asia supplies BETAFLOW CR 501 for water-bearing systems and BETAFLOW CR 551 for gas-field service, with the product and dose selected from fluid chemistry, metallurgy, flow, and field corrosion data.
Which BETAFLOW Corrosion Inhibitor Fits the System?
BETAFLOW CR 501 and CR 551 serve different production conditions. CR 501 is formulated for oil and gas systems exposed to water, carbon dioxide (CO2), hydrogen sulfide (H2S), and organic or inorganic acids. CR 551 is an amine-based option for gas-field equipment exposed to H2S and acids. A field trial is still needed because corrosive species, water cut, temperature, velocity, and injection location affect the required dose.
| Selection point | BETAFLOW CR 501 | BETAFLOW CR 551 |
|---|---|---|
| Primary service | Water-bearing oil and gas production systems | Gas-field production systems |
| Protected assets | Wells, pipelines, and process equipment | Wells, pipelines, and process equipment |
| Corrosion drivers stated for the product | H2S, CO2, and organic or inorganic acids | H2S and organic or inorganic acids |
| Application | Flush treatment or continuous injection | Flush treatment or continuous injection |
| Starting field range | 10-45 ppm of produced fluid | 10-100 ppm of fluid rate |
The ranges above are starting points from the product specifications, not fixed operating setpoints. Confirm the actual dose through field optimisation and corrosion monitoring.
BETAFLOW CR 501 Protects Water-Bearing Production Systems
BETAFLOW CR 501 is a water-soluble, film-forming corrosion inhibitor for oil and gas production systems. It protects pipelines and process equipment against metal deterioration and pitting associated with H2S, CO2, and acidic fluids.
| Physical form | Specific gravity | Water solubility | Application | Packaging |
|---|---|---|---|---|
| Yellow to dark brown liquid | 1.10-1.30 | Soluble | Flush or continuous injection; optimise from a 10-45 ppm starting range | 200-litre drum |
BETAFLOW CR 551 Protects Gas-Field Equipment
BETAFLOW CR 551 is an amine-based, water-soluble corrosion inhibitor for gas-field production equipment. Its protective film is intended to reduce metal deterioration and pitting from H2S and organic or inorganic acids from the well through the pipeline and process equipment.
| Physical form | Specific gravity | Water solubility | Application | Packaging |
|---|---|---|---|---|
| Yellow to dark brown liquid | 0.86 ± 0.1 | Soluble | Flush or continuous injection; optimise from a 10-100 ppm starting range | 200-litre drum |
What Data Is Needed Before Selecting an Inhibitor?
A usable recommendation requires recent fluid and operating data. Prepare water cut, CO2 and H2S exposure, pH, chloride or salinity, operating temperature and pressure, flow rate, metallurgy, corrosion history, and the available injection point. Also state whether treatment will be continuous, batch, or a system flush.
Corrosion coupons, probes, iron counts, inspection findings, and failure locations help establish the baseline and verify whether the selected program is controlling corrosion. Chemical feed should be matched to the available dosing pump system and reviewed alongside the wider oilfield chemicals program.
Common Questions
Is an oilfield corrosion inhibitor the same as a cooling-water inhibitor?
No. This BETAFLOW CR page covers oil and gas production fluids. Recirculating cooling water has different water chemistry, metallurgy, biological activity, and monitoring needs; see the separate cooling-water corrosion inhibitors range.
Can the injection rate be taken directly from the table?
No. The stated ppm values are initial field ranges. Final dosage depends on the corrosion mechanism, fluid composition, flow regime, injection location, and measured treatment response.
How can a buyer request a technical recommendation?
Send the operating and corrosion data through the Beta Pramesti Asia technical contact page. The review should confirm the service conditions, treatment method, monitoring plan, packaging, and site delivery requirements.
