Screw conveyor is widely used in drilling mud solids control & waste management as important transportation equipment. Proper use of screw conveyor can make the field job with small footprint and high working efficiency. Let’s draw some conclusions on screw conveyor application in drilling waste management.

1) Connection between mud solids control system & drilling waste management system

The screw conveyor can positioned paralleled with solids control system, equipment like shale shaker, desander, desilter (or mud cleaner, combination of desander & desilter). The paralleled screw conveyor can collect the drilling cuttings discharged from solids control equipment and transport to next slant screw conveyor. This screw conveyor is for feeding for Hi-G dryer or Vertical-G dryer.

2) Feeding for Hi-G dryer & Vertical-G dryer

GN drilling waste management system, the first separation phase is generally equipped with Hi-G dryer or Vertical-G dryer. They both can be used for water based mud, oil based mud & synthetic based mud. Generally, the Hi-G dryer is more proper for water based mud; vertical-G dryer is more proper for synthetic based mud with comprehensive consideration.

The screw conveyor can make the feeding more even/homogeneous, in this case, the working performance of Hi-G dryer or vertical-G dryer can be stable.

To acheive zero discharge for the drilling mud, GN Solids Control provide the dewatering decanter centrifuge with the flocculent unit.

The GN1500 Series 20FT Dewatering Unit provides a process of chemically enhanced configuration to remove the fine solids less than 5 microns from the water based drilling fluids.

Traditional Solids Control Equipment:

As it known that traditional solids control equipments like shale shaker,desander desilter, and decanter centrifuge will removes solids upper than 5 microns, for colloidal-size particles which is less than 5 microns will build up in the drilling mud system. To maintain the drilling mud properties, the operators have to dilute the drilling fluids with water, this consumes more water and create more drilling waste.

Advantage to use flocculent unit for the dewatering decanter centrifuge:

Dewatering Unit

By utilizing the GN1500 20FT dewatering flocculent unit, the result is a chemically enhanced flocculation of colloidal and ultra-fine drilled solids that can be efficiently removed with a GN dewatering centrifuge.

For limited and zero discharged closed loop system, the GN dewatering unit is a very important unit to keep the mud clean and reduce the drilling waste which has to be sent for treatment and disposal. Before entering the dewatering phase, for the weighted drilling mud, firstly it enters a barite recovery centrifuge to recovery the barite to the active mud system.

The GN 20 Ft containerized dewatering unit can be transported as a standard 20 ft container The system includes all the standard dewatering components .GN also have the dewatering decanter centrifuge available can be mounted on a separate telescoping skid or on the drilling mud tank.

Drilling waste management and zero discharge is a getting much popular recent years. It is important to get zero discharge on drilling waste management.  Many EPC company wanna source professional equipment and professional personnel on the potential projects with large profit.  The the drilling waste market capacity can reach 17 billion before 2018, it is said.

GN Solids Control is leading manufacturer for  drilling waste management equipment & solids control equipment; after some years experience accumulation, GN Solids Control can offer professional solution on drilling waste management and can answer the question most of the people faced with ” How to achieve zero discharge on drilling waste management “. This chapter will give a comprehensive knowledge of drilling waste (OBM & WBM) from three parts as below. And tell people how to achieve zero discharge on drilling waste management in Part 3.

1.  Source of drilling waste
2. Necessary drilling waste management equipment
3. Treating process of drilling waste and How to achieve Zero discharge of drilling waste

Part 1: Source of drilling waste

Source 1: Drilling waste from oil based mud drilling operations. The assessment is yet to be conducted

Souce 2: Refinery waste: Most of it is waste water, sludge, and the usual refineries waste ingredients. The refinery waste will be first recovered from large ponds and for those ponds to be remediated to original status where we will plant them with trees.

Source 3: Storage tank sludge: The tanks are yet to be calculated in terms of number and storage capacity. However, they are estimated to exceed the 50 tanks mark.

Source 4: Oil pits (there are many oil pits and waste management service company are trying to do land remediation to original state which means they will treat the crude to get it back to its crude status, soil back to soil and water to be recovered):

Oil pit case from Iraq drilling waste management market:

• There are over 120 oil pits to be treated.
• More than 60% are emptied from crude and what is left is sludge and soil to be treated.
• Average sizes are 100 miters in length, 70 miters in width and 5 miters in depth.
• We will be dealing with all of them, the ones that have sludge and soil left and the ones that are still filled with crude.
• The base of all pits is earthen. No concrete nothing else but earthen.
• Our task is to treat all pits and remediate the land to original status where we will plant them with trees.
