Task is a company of specialists dedicated to avoiding these hazards and increase the service life of drilling and well equipment. One of our specialties is mud cooling, and the Task mud cooling equipment has a number of features to maximize performance and reliability, at the same time ensuring environmental protection against leakages and other hazards. We specialize in both offshore mud cooling equipment based on the use of sea water as a main cooling agent and in onshore mudcoolers using air as a main cooling agent in combination with a closed circuit cooling system and optionally a compressor type cooler.

The Task onshore mudcoolers are based on a two step closed loop cooling design. The hot mud is passed through a plate heat exchanger, where a circulating water glycol mixture or water absorbs heat from the mud. Fan-cooled radiators lower the temperature of the cooling agent in turn, allowing efficient operation and secure well conditions. This system can be expanded by a compressor type cooling module to increase performance. Task mud cooling equipment is designed to consider the environment and operational as well as working conditions. Design and construction of the equipment guarantee optimum drilling conditions; if required enclosures and sound baffles can be installed for a further reduction of noise levels for crew and site surroundings.

Task disc separators are valuable instruments for the efficient processing of waste materials and the recovery of useful material from slop oil, lowering storage and dumping costs and offering an environmentally friendly alternative to traditional procedures for the processing of waste material. They can be operated with water as a control medium or low-viscosity organic fluids. Task disk separators are built with a self-cleaning bowl with a stack of conical disks. This will greatly enlarge the clarification area and give the separator a substantial capacity within a relatively small bowl volume. The self-cleaning bowl allows periodical discharging of separated solids (max. 1%) at full operational speed. To this end, the bowl ports around its perimeter are opened and closed by a hydraulically actuated sliding piston in the bowl bottom.

The opening mechanism allows both partial and total ejections of the bowl contents. For total ejection, the evacuation ports on the bowl’s perimeter are opened while the feed valve is closed. Partial ejection of the bowl’s contents occurs when the ejection ports are opened while the feed valve is kept open too.

For a simple and reliable operation, the Task disc separator is controlled by a Siemens Simatic C7 PLC: Furthermore, it is designed and certified for operation in Zone 1: the complete drive system is explosion proof. The entire unit is containerised, and mounted on top of a frame, which also holds a sludge tank and pump.

On drilling and storage locations drainage and scrub water may be contaminated by a variety of substances which may interfere with environmental friendly procedures or increase the costs of its treatment. Task has developed a water treatment unit to bring drainage and scrub water up to the standards for disposal into sewage systems or for re-use as cleaning water.

The main hardware of the unit, consisting of a buffer tank, pumps, dispensing systems for adding flocculants and stabilizing agents and tubing, is enclosed in a 20 feet container. Outside the container, the unit comprises a settling tank and a storage tank. Drainage and scrub water are pumped by a submersible pump from the corner pit into the buffer tank. From there, the water is pumped into the settling tank. During this process, chemicals such as polymers and FeCl3 can be added in-line to enhance sedimentation of the contaminants and bring the water quality up to a level that will meet the demands for sewage or wash water. From the settling tank, the treated water flows passively into the storage tank which is situated below the sedimentation unit. From the storage tank, it can be pumped to storage tanks for disposal to sewage plants or to the rig for cleaning purposes.

With this water treatment unit, Task’s offers a comprehensive solution for the problem of contaminated drainage or scrub water. The unit allows you to bring these waste waters up to a quality level which makes them suited for affordable elimination or re-use on site, and helps you to meet environmental requirements without complex and costly measures.

The Task TKL-series are especially designed for use in the drilling industry. High G-force in a shaker is essential to convey the amount of cuttings generated while drilling hole, to dewater drill cuttings to reclaim expensive drilling fluids, and to minimize waste. While drilling top hole sections, where heavy, high volume cuttings are typically encountered, shakers need to generate high G-force to effectively convey dense solids.

However, as conditions change in drilling and fl uids, the G-force of the TKL- 448 AG LE can be adjusted with the simple twist of the wrist at the control panel, therefore changing the cuttings conveyance velocity. This can be done without shutting down the shaker and adjusting the weight settings on the vibrator motors. As a result, Task’s TKL-448 AG LE can provide drier solids, improved drilling fluid recovery, longer screen life and reduced operating costs.

All units can be provided with 400V / 50Hz or 460V / 60Hz; generate a noise level less than 80 decibels (dB); and are fitted with an adjustable deck capable of inclinations of -2 to +5°. The high G-Force design will effectively convey the solids across the screens. All units will be provided with explosion proof motors or standard motors for HDI and tunneling.

Combining mud cleaning equipment based upon varying physical principles may give you the best of several worlds. With one set of equipment, you will be able to eliminate any particles larger than 15-20 microns. This will allow you to meet most environmental demands and save substantially on your operational costs.

The mud cleaner combination consists of two sets of hydro cyclones: a desander to eliminate particles of 120 – 60 μ, and a desilter which eliminates particles smaller than 60 to 20 μ. The combination of varying physical mud cleaning principles results in a high capacity mud cleaning combination with high a operational efficiency and minimum maintenance, repair and replacement costs.

Hydro cyclones form an extremely cost efficient first step to convert sand and silt loaded mud into relatively particle free fluids. Drilling fluids are pumped at high speed, up to 1500 GPM ( 340 m3/hr) at a pressure of 30 to 40 PSI (2,2 to 2.8 bar) into the hydrocyclone manifold, feeding each hydrocyclone equally. The finer particles together with fluid moves upward and escapes through the overflow tube of the hydrocyclone, a small portion of the liquid, together with the coarser particles, is eliminated through the underflow vents, and undergo a final cleaning step in the shaker resulting in ecologically sound operations and lower maintenance and disposal costs.

Task’s know-how and experience are essential elements in the quality and versatility of all Task equipment, including this desilter / desander and shaker combination. As all Task equipment, it can be delivered completely to your specifications; our modular design practices and wide experience in the field of oil industry equipment will ensure short delivery times and problem free commissioning.
