Water Treatment Services

CrudeSorb is a proprietary adsorption media based on resin, polymer, and clay technology. It has been proven to be extremely efficient at removing oil, grease, and soluble organics from water.

CrudeSorb has been developed specifically for this purpose and is packaged in radial-flow, nonferrous canisters comprised of a cloth mesh and polycarbonate sealing caps at either end of the canister. Housing the CrudeSorb adsorption media in this way allows for quick media change outs - essential on temporary flow back applications or at remote locations.

At each treatment stage our technology incrementally improves the water quality. This stepwise approach to processing provides assurances that the discharge specification is met or exceeded.

This conservative approach has also made CETCO Oilfield Services the most successful in online applications.

CrudeSorb^® MR is a new media material that can be packed in the canister similar to the CrudeSorb media. This new media is still based on organoclay technology but it has been heavily modified to enhance mercury and arsenic adsorption through both physical removal and chemical bonding. CrudeSorbMR is effective on all sources of mercury including the organic type of mercury, mercury element (zero valent), and mercury ions (both I and II valent). Additionally, CrudeSorbMR can also be as effective as the traditional CrudeSorb media to remove oil, grease, and other organic contaminant molecules when needed.

CETCO Oilfield Services Hi-Flow Process can treat high rates of produced water, allowing the operator to return the produced water back into the environment in compliance with state and federal regulations. Our Hi-Flow Process gives you the flexibility you need in having one solution for many applications - the Hi-Flow process can handle small to large volumes of liquid, from 1,000 BWPD to more than 40,000 BWPD; it is not hindered by large fluctuations in oil and grease inlets; and it can be used on projects with short or long durations.

CrudeSep is a compact 4-phase separator designed to treat produced water, reducing oil content in the water to acceptable discharge levels over a wide range of flow rates and conditions. Oil in water reduction to 5 ppm (or below 10 ppm) are achievable dependent on water conditions.

CrudeSep is a produced water treatment vessel operating at near atmospheric pressure. Oil recovery and solids removal is achieved by induced gas flotation and a cyclonic motion system. Produced water enters the CrudeSep vessel through tangential nozzles which are geometrically spaced to eliminate the effects of surge or slug flow. Influent fluid enters a treatment zone where continuous recycle maintains a minimal spin providing sufficient centrifugal force for immediate oil/water separation. Gas bubbles are injected with recycled water below the inlet water nozzles to maintain a continuous supply of 'flotation' gas.

Flotation effects and centrifugal forces will bring the oil droplets to the surface where they are subsequently skimmed to the oil bucket. CrudeSep can also be used upstream of CETCO's Hi-Flow™ and CrudeSorb^® technologies as a primary oil separation system.

CETCO Oilfield Services wastewater treatment experience has culminated in the design and implementation of a multi-stage treatment package. FlexTreat is a system which combines conventional water treatment technologies and proprietary media to effectively process wastewater of wide ranging and uncertain composition. Wastewater from a variety of different sources which contains solids, crude oil, drilling waste and production chemicals is treated to stringent discharge criteria. By employing gravity separation, chemical treatment, clarification, filtration, polishing and aeration, FlexTreat provides a complete solution to problematic fluids.

Typical design inlet parameters in the region of 100,000 ppm oil and 80,000 ppm solids can be effectively treated to < 20 ppm oil and < 30 ppm solids concentration at a rate of 37.68 bbls per hour. Simple operability and process flexibility are the key to the effectiveness of the FlexTreat package.

The Wellhead Cyclonic Desander is an innovative product from CETCO which enables the recovery of sand product from multi-phase well streams during well clean-up operations.

The well fluids are routed from the wellhead to the upper section of the desander vessel. The well fluids enter the vessel then hit a deflector plate offset at a 45° angle resulting centrifugal force exerted on the spinning fluid pushes the denser phase (sand) to the wall of the vessel. The clean well fluids at the center are forced up and out of the overflow line. The sand drops into the lower part of the vessel due to gravity. Once filled, the accumulator/lower section of the vessel's contents are pushed out using the pressure within the unit into a sieve tank arrangement. While the lower section of the unit is being emptied you can still flow into the top half. Therefore, the well does not need to be shut-in at any period of the clean-up program.

Our turnkey engineering group is focused on cost-conscious, technologically innovative solutions which prevent pollution, minimize waste, and comply with environmental regulations.

CETCO Oilfield Services utilizes a variety of technologies based on our customers' requirements. Alone or in combination, CETCO Oilfield Services Company's technologies can remove oil, solids, and toxic material from water based streams. CETCO Oilfield Services continues to develop new technologies to consistently provide unique solutions for all phases of oilfield production.

CETCO Oilfield Services can remove bulk oil through gravity and flotation technology. The process stream enters the 120 barrel separation (weirbox) or sparging tank comprised of four individual compartments. Each compartment has chemical injection, sparging, and oil separation capabilities. The tank provides a great deal of flexibility in breaking emulsions, segregating solids, and recovering oil. Any unexpected surges of oil, solids, and undesirable waste can be isolated and treated independently. Oily water is progressively cleaned from one compartment to the next.

NEMOH (Nomadic Environmental Media Operated Host), is a novel, patent pending treatment vessel developed by CETCO Oilfield Services for processing and retaining fluid in a subsea environment. It is remotely operated and can operate at depths over 6,000 ft. NEMOH is an innovative solution for the problematic treatment of fluids at subsea levels and offers flexibility - it is able to be recovered in a reverse process, disconnected, or be guided by an ROV using a ship's winch, or it can be moved along the seabed to another location for another application. It is also extremely effective, since it can treat a number of constituents depending on whether the materials need to be oxidized, coalesced or neutralized because it can be operated with different media types. NEMOH may also be operated as a stand alone vessel (single pass) or in combination in series (multi-pass) with additional vessels utilized for processing fluid with higher levels or multiple constituents.
