What is produced water in the oil and gas industry?

Produced water is the largest waste stream generated by the oil and gas industry, co-mingling with crude oil and natural gas as it comes up from the ground. In mature fields, like those in Trinidad and Tobago, the volume of produced water can significantly exceed that of extracted oil, often 3 to 10 barrels of water per barrel of oil. It contains a complex mixture of contaminants requiring specialized treatment.

How does AMPAC USA treat produced water for oil fields?

AMPAC USA employs multi-stage hydrocarbon separation followed by advanced reverse osmosis (RO) processes to treat produced water. This comprehensive approach effectively removes oil, suspended solids, and dissolved contaminants, including high TDS levels. The treated water is then rendered safe for various uses, such as human consumption at field campsites.

What types of contaminants are typically found in produced water?

Produced water contains a complex array of contaminants, including dispersed and dissolved hydrocarbons, naturally occurring radioactive materials (NORM), and heavy metals. It also features high levels of dissolved solids (TDS, often 10,000–300,000 mg/L), bacteria, and scale-forming minerals. Untreated discharge of this water is prohibited in most jurisdictions due to its hazardous composition.

Why is treating produced water critical for oil and gas operations?

Treating produced water is a critical operational necessity and environmental obligation for the oil and gas industry. It addresses the largest waste stream generated globally, preventing the discharge of hazardous contaminants like hydrocarbons and high TDS into the environment. Effective treatment, such as AMPAC USA's systems, also enables beneficial reuse, like providing potable water for field campsites.

Can produced water be treated to be safe for human consumption?

Yes, with advanced purification technologies, produced water can be treated to be safe for human consumption. AMPAC USA's systems, for example, utilize multi-stage hydrocarbon separation combined with reverse osmosis to remove a wide range of contaminants. This process ensures the water meets potable standards, making it suitable for use at field campsites.

Water Separation In Oil Fields In Trinidad

Quick Answer: AMPAC USA has completed the installation of two produced water treatment and separation systems for oil fields in Trinidad and Tobago. These systems use multi-stage hydrocarbon separation followed by reverse osmosis (RO) to remove oil, suspended solids, and dissolved contaminants from co-produced water, rendering it safe for human consumption at field campsites. The systems address one of the oil and gas industry’s most critical environmental and operational challenges: the treatment and reuse of high-volume produced water.

Ampac USA has just finished the installation of two Water Treatment / Water Separation Systems for Oil Fields in Trinidad and Tobago.

The water comes out co-produced with the oil. These Water Treatment Systems consist of many stages to reduce hydrocarbons from water, then treated with reverse osmosis process to be used on camp sites for human consumption.

Produced Water Treatment in the Oil and Gas Industry

Produced water — the water that comes up from the ground co-mingled with crude oil and natural gas — is the largest waste stream generated by the oil and gas industry globally. For every barrel of oil extracted, between 3 and 10 barrels of produced water are typically generated. In mature fields like those in Trinidad and Tobago, this ratio can be significantly higher. Managing this water is both an operational necessity and an environmental obligation.

Produced water contains a complex mixture of contaminants including dispersed and dissolved hydrocarbons, naturally occurring radioactive materials (NORM), heavy metals, dissolved solids (TDS often 10,000–300,000 mg/L), bacteria, and scale-forming minerals. Untreated discharge is prohibited in most jurisdictions. The preferred approach is treatment and beneficial reuse — for irrigation, industrial processes, or potable water production for field personnel.

AMPAC USA’s oilfield water treatment systems use a multi-stage process engineered for produced water’s unique contamination profile. Stage one employs induced gas flotation (IGF) or API gravity separators to remove free oil. Subsequent stages use coagulation/flocculation, media filtration, and activated carbon to reduce residual hydrocarbons, suspended solids, and organic compounds. A final reverse osmosis stage reduces TDS, heavy metals, and dissolved organics to EPA and WHO drinking water standards — producing water safe for campsite consumption and industrial reuse.

The Trinidad and Tobago installations represent AMPAC USA’s established expertise in Caribbean and Latin American oil-producing regions. Our systems handle high-salinity, high-hydrocarbon produced water characteristic of mature fields, with capacities from 5,000 GPD to over 500,000 GPD. Custom skid-mounted configurations allow rapid field deployment with minimal civil works.
