Slop Treatment

Soiltech is using our market leading Slop Treatment Technology (STT®) for treating Slops. The STT is a mechanical technology which is used on location, treating water contaminated with oil and particles.

Utilizing the STT, Soiltech has treated more than 400 000 m3 (2,500,000 bbls)  of oily water/slop/sludge from drilling and P&A operations. On average, 95% of the total slop volume is treated on location at an average of 5 ppm. The treated oil and water is reused in the drilling process. The treated water may alternatively be discharged to sea or ground.

The STT is also used for Brine Recovery after the displacement of reservoir drill-in fluids to reduce well cost. Other uses of the STT include Cutting Mud Weight.

Water treatment

Soiltech offer technologies for treating Produced Water which is water produced as a biproduct during oil and natural gas development. Produced water contains soluble and non-soluble oil/organics, suspended solids, dissolved solids, and various chemicals used in the production process. 

The STT Purifier is a technology developed by Soiltech which is used to reduce Total hardness, Chlorides and Total Dissolved Solids in the water. The STT Purifier is also suitable for applications aiming at reducing the content of Arsenic, Barium, Cadmium, Chromium, Lead, Mercury, Selenium and Silver in water.

The patented biodegradable chemical Sorbfloc® is used in the treatment of produced water. Sorbfloc enables the re-use or discharge of water, free from pollution, microplastics and environmental toxins.


Sorbfloc is a green product from the hydrocolloid family able to attach to even the smallest particles or oil droplets in water. It is characterized by excellent cross-linking capabilities. These capabilities, when activated according to the Soiltech process, instantly and irreversibly flocculate pollution in water to large, easy separable super strong flocks.

Sorbfloc can also be used to treat contaminated water in the Aquaculture business, Municipals and other industries.

Cuttings – Skip & Ship handling

Soiltech’s skip and ship cutting system is designed to handle large amounts of cuttings in the most efficient manner. The ST-510 blower is a multi-purpose blower unit with gravity feed. This is a proven and versatile machine operated solely by air for transferring the drill cuttings into skips or tanks for further handling. The highly efficient unit can transfer cuttings over long distances. 

Soiltech’s modular-based skip working station ST-CS is designed for multiple-choice setup, which means that there is no limitation to the number of skips. The frame can be used as a singular working station or in a combined setup. The frame is fitted with a two-level setup for the safety of the operator and personnel around the working area.

Benefits of Soiltech’s cutting handling system:

  1. Fully redundant blower capacity
  2. Blowers may be serial coupled for increased capacity
  3. High capacity enabling fast drilling
  4. Control panels are redundant and easily replaceable
  5. Small footprint
  6. Zone 2 rated

Cuttings – Bulk handling (rig)

Soiltech offers of a fully pneumatic bulk cutting handling system for transfer to the rig’s bulk storage tanks. We have developed a novel Multi Discharge Tank (ST-MDT) which has proven to be very effective, with capacity to handle large amounts of cuttings in an efficient manner.

Cuttings – Bulk handling (boat)

Soiltech has experience from Cuttings – Bulk Handling (transfer to boat). We are in the process of developing our own Cuttings Boat Storage Tank (ST-CBT) for efficient and safe Bulk handling to boat.

Cuttings Treatment

Soiltech has developed a patented technology for treating OBM and WBM cuttings. The Cuttings Treatment Technology (CTT®) is a non-thermal, mechanical technology. The CTT unit has a high treatment capacity and is introduced to the onshore market.

The treatment process has no ignition sources and has a lower energy consumption than existing thermal solutions. The cuttings are treated according to the requirements for oil on cuttings and may be reused in cement production or road fills. The treated water and oil is recovered for reuse in the treatment process or for building new mud.

Swarf Treatment

Soiltech’ s Swarf removal system (ST-SRS) is a field proven market leading technology. It is a new and upgraded Swarf unit to optimize the process and minimize exposure and personnel onboard (POB). The unit handles all mud and swarf from milling operations. The system runs with an automated magnetic cycle and pump rate. If required, it can be operated using manual input.

The ST-SRS is built to have contingency under the entire operation. The dual pump setup is connected to the level sensors in the tank. If the tank volume raises the pumps will adjust accordingly to keep the volume and flow at desired levels. The ST-SRS has an advanced monitoring system which can be tied into the rig’s volume control system, allowing the rig to monitor the flow from the unit.

Cleaning services

Soiltech delivers high quality tank and pit cleaning services that follow strict procedures regarding PPE to ensure safety, integrity and the environment. Our offshore personnel is trained not only for operating the treatment equipment, but also to be a sparring partner when it comes to handling the drilling waste. Our operators have extensive knowledge of the different types of waste in a pit or tank, making our operators ideal for supervising the cleaning and emptying of these tanks.

Combining the handling of this waste with our slop treatment units enables treatment and discharge of the volume generated during tank/pit cleaning, according to discharge regulations, thus reducing the need for backload to shore. Soiltech provide the latest versions of protective gear combined with the best available operating technologies.
