Petroleum Industry

Water treatment in the petroleum industry is a critical process aimed at treating and managing various types of water associated with petroleum operations. This includes produced water, which is water that comes up along with oil and gas during extraction, as well as various wastewater streams generated during refining, processing, and other operations. Effective water treatment is essential to meet environmental regulations, protect water resources, and ensure the safe and sustainable operation of petroleum facilities.

Water Challenges in the Petroleum Industry

Oil and gas production generates several types of water that require treatment:

• Produced water – Water that comes out of the well along with oil and gas
• Fracturing flowback fluid – Water returned after hydraulic fracturing

• Refinery wastewater – Water from crude oil refining and processing

Common problems:

• High oil content and suspended solids
• High salinity and hardness → scale formation
• Corrosive substances → equipment damage
• Bacteria (e.g., SRB) → biofilm and microbiologically induced corrosion (MIC)

• Strict discharge limits from environmental agencies

Our Chemical Solutions by Function

We supply a full range of chemicals to solve specific water treatment problems in the petroleum industry.

Corrosion Control

Frequently Asked Questions

Q: What is the most common water treatment problem in oilfields?
A: Scale and corrosion are the top two issues. We offer HEDP and ATMP for scale control, and corrosion inhibitors to protect pipelines.

Q: Can you help me choose the right biocide for my produced water?
A: Yes. For sulfate‑reducing bacteria (SRB), Glutaraldehyde or THPS is often used. For general bacterial control, Isothiazolinone is a common choice. Contact us with your water analysis.

Q: Are your products suitable for offshore platforms?
A: Yes. Many of our chemicals are used on offshore facilities. We provide proper packaging and documentation for safe transport by sea.

Q: Do you provide free samples?
A: Yes. We offer free samples of most products for pre‑order testing. Just tell us your application.
