Drawing on years of experience in water treatment, CETCO has designed a rental fleet that meets a vast variety of flow rates, temperatures and pressures. Our turnkey approach to the treatment of oilfield wastewater streams places personnel and safety first. Dedicated to maximizing our customer’s investment returns, CETCO provides consistent results to produce environmentally compliant processes with increased oil recovery and ultimate production.
Since our founding in 1996, CETCO Energy Services (CETCO) has been the leader in offshore water treatment of flow back fluids generated from acid stimulations, work-overs, well completions, and water based pipeline fluids generated during commissioning, hydro-testing, and flushing activities. Our innovative produced water treatment technologies, utilized to treat large volumes in a small footprint (on a temporary or permanent basis), have been awarded for effectiveness and environmental sustainability. Our company is globally recognized for its fluid treatment technologies, service expertise, and dependability in achieving the highest environmental standards possible. Expanding on our heritage, and using our proven water treatment capabilities, CETCO has become a valued partner in water treatment and resource conservation in onshore energy production.
CETCO’s mobile water treatment plant, the Onshore ElectroCoagulated System (ECS), has treated flowback fluids that have been recycled up to 10 times at a single site, continuously providing all the water needed for fracking, without relying on any additional external sources. CETCO’s Onshore ECS has reduced client operating costs by more than 40%, in water and fuel savings alone.
Hydraulic fracturing, or fracking, has been front page headline news across the United States. The technology, though decades old, has come to the forefront as an integral part in the production of hydrocarbons from onshore shale formations. To extract oil and gas from these formations, companies use horizontal drilling to laterally penetrate the oil and gas rich shale deposits. This Drilling Technique allows multiple wells to be drilled and produced from a single well pad. As the well is being completed, large quantities of water, sand and chemical additives are injected at extreme pressures causing fissures in the semi-impervious shale from which the hydrocarbons will eventually flow to the surface for processing.
Production from these shale plays has provided exceptional returns. Huge amounts of previously unrecoverable oil and gas have been added to our country’s reserves. The exploitation of shale plays has made the United States less reliant on imports and will, in fact, eventually lead to the export of oil and gas. As with most positives, there are negatives to address.
The major conundrum of fracking is water supply, a necessity. It has been estimated that a typical horizontal fracked well can consume between 1 and 8 million gallons of water, depending on its depth and length of wellbore. The water is supplied either by water wells drilled on-site or by truck, one tanker at a time.
Once used for fracking, the water is contaminated. When returned to surface, “flowed back”, the contaminated water must be handled properly. Contaminates consist of chemicals, an integral part of the frac fluid makeup, and produced formation liquids which contain significant amounts of produced water and condensate. Traditionally, these flowback fluids have been re-injected into abandoned wells “on-site” or trucked off premises for further treatment and/or disposal. The former method runs the risk of soil and groundwater contamination, while the latter results in hundreds of trucking hours which significantly increases cost and risk associated with traffic and/or environmental incidents.
Due to its scarcity around fracking sites, water is a premium commodity and as demand escalates, so do cost. This situation has led to water management through recycle, or reuse. Recycling fracking flowback fluids is a complex challenge and requires unique expertise.
CETCO’s approach to water management and recycling is to assure that all water delivered to a “production development” stays on the property to be reused as a continual resource. This strategy includes on-site flow back water treatment to eliminate on-site disposal or transportation off-site for treatment and/or disposal. On-site treatment, eliminates water management headaches, reduces water handling costs and provides fluid quality that can be utilized, or re-utilized, as a base for frac gel or slick water.
The CETCO Onshore ElectroCoagulation System (ECS), is an innovative mobile water treatment plant that can be transported to even the most remote field adding mobility and flexibility to completion, fracking and production operations. The flexibility of our process allows CETCO to produce the exact quality of water required to maximize the effectiveness of each fracking job. The package includes a mobile trailer that houses testing, online monitoring, and process equipment, specifically designed by CETCO, to meet the exacting water quality standards of our clients.
The Onshore ECS coagulates colloidal particles and floats them to the surface and destabilizes emulsions at volumes up to 10,000 barrels of treatable liquids per day (BPD). During subsequent stages of the process, solids are removed, bacteria is disinfected, and the water is clarified to meet the customer’s specifications for reuse–all without disposal or leaving the site.

CETCO Energy Services has built a global reputation for providing leadership in-situ water treatment services to the oil and gas industry. Our capabilities are recognized and sought after in all of the world’s major energy centers including the North Sea production sectors.
The North Sea oil and gas activity is closely aligned with environmental regulatory and advisory bodies that cooperatively oversee the marine environment and those operating in it. Offshore activity in the UK sector, from exploration through decommissioning, is regulated by the Department of Energy and Climate Change (DECC). The agency sets best practice standards for safety and the environment and conducts regular inspections to insure compliance.
Criteria for discharge of oil-containing produced water was established by Oil Pollution Prevention and Control (OPPC) regulations in 2005. It mandates that oil content must be less than 30 milligrams per liter (mg/l) in the produced water. In 2013, the approximate 90 UK offshore installations averaged 14.35 mg/l.
As a contracting partner with 14 other countries, the UK has implemented improvements exceeding the 15% reduction in the quantity of oil in produced water as recommended by the OSPAR (Oslo and Paris) Convention for the Protection of the Marine Environment of the North-East Atlantic.
CETCO is a visible partner and participant in environmental protection. Our mission is to assist offshore producers in controlling contaminants in produced water from their facilities. We work closely with our clients and regulators to assure water management and compliance with standards for all North Sea sectors. A goal, using our proven risk-based methods, is identify oil components and toxicology, and to treat them in produced water for cost effective re-injection or over-the-side discharge rather than costly transport to shore for further processing.
CETCO has established a full-service base from which it provides the necessary equipment and technology to best assist our clients. From this base, our North Sea presence extends to project areas in Middle East waters as well as North Africa and the Mediterranean. Our physical offshore capability is enhanced by an extensive inventory of equipment. We offer fully equipped barge units operating from our Aberdeen, UK shore base that have the capacity to treat as much as 25,000 barrels/per day of produced water cleanup. These units are complemented with mobile spreads capable of easy adaptation for set-up on the platform or on supply vessels. Our Hi Flow technology has been shown to be highly effective in removing soluble organics from water. Additionally, we have bench type and pilot units that provide testing of proposed concepts on the offshore facilities or in our onshore laboratory prior to setting up full scale units.
