The Drill cuttings Management solution is designed to help maximize compliance with the waste management hierarchy principles, as well as ensuring that local regulations and standards are complied with. Ultimately, disposal will be required in all cases, be it solids and / or liquids.

Drill cuttings management solution usually including but not limit to:

1 collection of drill cuttings

There are various ways to collect the drill cuttings from the solids control system( shale shaker, mud cleaner, decanter centrifuge). Firstly you need a cuttings blowing pump to blow the drill cuttings and waste produced by centrifuge from a collection place in the site to a drill waste storage tank or directly to a transferred truck or boat, they called it ”bulk tank”. Then Screw conveyors are used to transport drill cuttings and centrifuge waste from one location on the rig to another, probably to a vertical cutting dryer in the drilling waste management system.

2 Storage of drill cuttings

A Drilling Waste Container is to storage drill cutting, centrifuge waste and pit cleaning wastes generated during drilling operations. The drilling waste containers are typically transported to a treatment and disposal site for further processing.

After the drilling waste is treated by vertical cutting dryer, the cuttings will be collected by a small waste container and be transported to other place, the fluids are pumped to high speed decanter centrifuge for further process.

If you have over 30 years experience for drilling, you will know, what is real required and what is not for close loop mud system. Sometimes people just seek for unrealistic specifications, which did not mean good for the operation. GN solids control would like to share your new idea about the drilling solids control, and put your idea into realization. We have the ability to design as your layout, no matter  you choose us as the complete system manufacturer or not.

close loop mud system

Recently drilling has been changed a lot, the old experience did not work, people has their own new design. “Zero discharge mud systems” are urgently required because of the environment protection. Auger box, screw conveyor can be used to collect the drilling cuttings from shale shaker, desander, desilter, mud cleaner, dewatering unit and centrifuge, then transfer them to a catch pit for later processing. In some development company where the government did not have strict regulation on environment protection, they even do not use any mud system, and let the drilling fluids discharged directly. They may face big problem in the future.

Dewatering unit is required to work together with the system, it can make further process of the fluids after processed by centrifuge after the well is finished.

The mud tank is designed similar to 40 feet standard container, it is more convenient to transport in any countries in the world. All the lifting device, dimension, skid is same with container, and we put GN solids control equipments on top of it.

If you required Close Loop mud System for oil & gas drilling, pls contact GN solids control, our service including design, consultant, manufacture and shipment.

Generally speaking, decanter centrifuge plays a role in separating solids from liquids. Alfa Laval decanter centrifuge is one of the best sold centrifuges in the world, especially in South America. The other brands in South America market including Derrick, MI-Swaco, NOV, Derrick, GN, etc. GN solids control is new brand player in the market, but fast developing.

How a decanter centrifuge works

A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity.

When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required.

The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually “ploughed” out of the pond and up the conical “beach”.

The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl. Baffles within the centrifuge casing direct the separated phases into the correct flow path and prevent any risk of cross-contamination. The speed of the screw conveyor may be automatically adjusted by use of the variable frequency drive (VFD) in order to adjust to variation in the solids load.

We are looking for Drilling Cuttings Screw Conveyors partner,since we are solids control system manufacturer.When designing a total mud system,we need to integrate drilling cuttings screw conveyors.

  1. Drilling Cuttings Screw Conveyors (Augers)

1 x ±24ft screw type cutting conveyor fitted with independent electrical motor and with sensor capable to stop the engine if any alien body is engaged into the screw.

Conveyor should be calculated to absorb overflow of cuttings when drilling 26” or 17” hole (1000gpm flow rate).

1 x ±36ft screw type cutting conveyor as above.Which are used before the drilling mud shale shakers.

We only work with manufacturer for drilling type cuttings converor,if you are interested,please send your info. to info@gnsolidscontrol.com.
