OBM which is known as Oil-based mud , the Oil-based mud is a mud where the base fluid is a petroleum product such as diesel fuel.

 

When treating OBM,most user need make OOC as low as they can, to recovery most fluid,because oil based mud is very expensive and if many fluid get away from drilling fluid,it will mean left fluid will pollute the environment,and some government not allow it

Based on this situation,GN engineer team design drilling cutting management system -GNCM-40,to recovery most fluid,and let user easy to treat discharged solids part

This system is mainly include Vertical cutting dryer and decanter centrifuge,and speed of centrifuge was advice adjustable to make separate result best

The cutting point of vertical dryer is 0.25-0.5mm,and most solids part will separate out,and centrifuge will treat rest fluid,the cutting point was 2~5μm,after that,most useless solids part will be removed,and the fluid can back to mud system to be reused

The OOC(oil on the cutting) after vertical dryer can be under 5% mostly,and this percentage means the solids part not include much fluid,and sludge treatment quantity reduce a lot,many cost for sludge management can be saved

Some point about vertical cutting dryer:

The screen of vertical cutting dryer is spare parts,local engineer should check it every 3month,to make sure equipment always stay at best state

The vertical dryer was good for treating cutting from shaker well,but for solids from centrifuge can’t refeed to vertical dryer because of solids size not suitable,and the solids will stick the screen

For now, GNCM-40 system already succeed running in many country’s and help client save money for waste manage

Please visit GN solids control learn more detail if interested about it

As solids control equipment supplier,GN name part number for spare parts of different equipment like shale shaker,centrifuge,vertical cutting dryer,Engineer is always keep developing equipment the model number is freshing every 1~2 years,it caused one equipment can use spare parts based on different part number,when client’s need maintenance,we always advice provide part number,for our exact and fast find suitable product for equipment

For stable deliver time,GN may have not only one spare parts supplier to keep fastest supply for client,some time,one supplier’s ability is not enough for some big project,ans we will name different part number based on supplier,to make sure client get same quality product,and better use experience

GN also was shale shaker replacement screen supplier,we will meet some client use mesh number and screen to find suitable replacement screen,but we find it will make mistake sometime,because most shale shaker supplier will use API/Part number to supply right screen,and mesh/size will make misunderstand

We advice client provide screen’s OEM part number or shaker model and API number to make sure we supply suitable replacement screen to do solids separation,and get good result

Replacement screen is special product for solids control,because wrong API number choose will cause rest equipment not work well,so,we use part number to help client find right product and save unnecessary lost

More question,please feel free to contact GN solids control

When make plan for placing solids control equipment like shale shaker/centrifuge/vertical cutting dryer/pump in jobsite,we need consider keep whole system running well and not use much space

Some engineer in drilling company like put equipment in top of mud tank,this way is easy to manage drilling fluid,and transfer will be easy,some big drilling work will choose this way,and the feeding pump install at side of tank,the whole system is more compact

In some mud service company,engineer need more useful volume for drilling fluid,solids control equipment and mud storage are separated;also it won’t need much equipment,the owner will install equipment in the skid,make concrete plinths in bottom,this way is easy to check equipment’s work state,better for maintenance,and can change pipe design,fit different request,in most LMP,they choose this solution,the skid can’t move,but easy to manage

For some small project,equipment not much,and drilling fluid request not high,the worker will put most equipment at land,and some important equipment will install in one small tank,the system will separated like different modular,can fit different kind drilling work,no need much equipment

When  compare produce cost,mud tank will be expensive for shipment,some client will choose to build it at local,GN will support give advice by design or drawing,the skid price is not that high,but it not good for move some time,most time just mud service company will choose it,maybe they will need telescopic,GN have this design;some HDD drilling client,prefer package equipment tank,and other equipment separate,to save unnecessary cost,GN did it too,because we have a experience engineer team,to give best support for client

GN solids control is equipment manufacturer and package system solution company

It’s a most technique used in a drilling rig to separate the solids part in the drilling fluids that are crushed by the drill bits and carried from well surface. Normally, normally one solid control system contains five stages: shale shaker/vacuum degasser/desander/desilter/centrifuge,and most equipment install in top of mud tank

Most engineer will call mud system as 4 phases solids control process or the 5 phase purification system. like shale shaker, vacuum degasser, to Desander cone, Desilter cone, and the decanter centrifuge. Based on different working principle and separation point. The well drilling will request this system to process drilling fluid. but, with different well depth and drilling condition the system designer need make different configuration and different result.

Solids control is most use in oil and gas drilling,but for request of separation,more and more industry plan to use it

1.Separate big partical and impurities from drilling fluid,to clean it and recycling use,to save keep less cost,and less discharge,for better environment,normally will use shale shaker/degasser/decanter centrifuge/desander/desilter/related pump and mixer

2.In some river clean project,need remove dirty mud from river water,decanter centrifuge will be good choice to control solids part from 2-5μm

3.When meet mining job,solids control will give support by separate and recycling,it will request shale shaker and decanter centrifuge mostly

4.Some dewatering system will need decanter centrifuge to treat polymer,to make better solids control

5.Few builing company are trying use solids control to reuse water and material,avoid un necessary cost

6.Liquid food area will request decanter centrifuge to raise quality,we supply solution too

GN solids control welcome all separation request,and give best solution

GN solids control provides the engineering and design of 3-phase separator internals that target high gas volumes and primary L/L dispersions.

Our scope includes the design, engineering and delivery of

 

1. a) The inlet gas distributor
2. b) The foam breaker along with the the L/G separator
3. c) The dimensional design of the inlet compartmeent, the settling compartment and

the product outlet compartment

1. d) The separation of the aqueous and hydrocarbon liquid phases utilizing ether plate pack type or wire mesh coalescers Ensepatec provides a process guarantee for

 

1) The removal efficiency of liquid droplets in the gas stream and the maximum liquid content in the outlet gas stream

2) The maximum content of water in the oil phase

3) The maximum ppm-level of oil in the water outlet flow

 

Materials of constructions are high grade stainless steel or nickel-based alloys

 

 This design eliminates the need for a liquid interface controller. Both the oil and water flow over weirs where level control is accomplished by a simple displacer float. The oil overflows the oil weir into an oil bucket where its level is controlled by a level controller that  operates the oil dump valve. The water flows under the oil bucket and then over a water weir. The level downstream of this weir is controlled by a level controller that operates the water dump valve.

The height of the oil weir controls the liquid level in the vessel. The difference in height of the oil and water weirs controls the thickness of the oil pad due to specific gravity differences. It is critical to the operation of the vessel that the water weir height be sufficiently below the oil weir height so that the oil pad thickness provides sufficient oil retention time. If

the water weir is too low and the difference in specific gravity is not as great as anticipated, then the oil pad could grow in thickness to a point where oil will be swept under the oil box and out the water outlet. Normally, either the oil or the water weir is made adjustable so that changes in oil/water specific gravities or flow rates can be accommodated.

As the main part of solids control system,Decanter centrifuge is one of GN’s most important protect
There is some point user should mention when installing and using:
1. The liquid discharge port should use soft tube when transfer, to avoid effect centrifuge’s balance when running
2. Hydrodynamic coupling will be installing in fixed speed centrifuge,for spped raise slow and working current not over limited,,this unit can prolong centrifuge’s service life
3. Limited system for centrifuge is important when equipment running,like electriclty limited,when the screw blocking by treated material,the momentary current will be very high,limited system will find it and cut power at first time to protect machine,GN’s centrifuge make overall protect design to keep solids control work running well and equipment life longer
4. Keep watching the state of equipment is very useful,the whole centrifuge will start shake when blocking,install detector to the control system will help user make first time decision to solve problem
5. Temperature of equipment was indicate when working,for example about bearing,the temperature will be very high when oil shortage,it will broken if do not have action,the motor’s temperature will be very high when screw sucking by material
6. Schedule regular time to get active, and stick with it,and do regular maintenance can keep quipment at best state and service longer,tosave money for buying new one,for example,the tiles of screw should be fixed after long time using,or the droped part will damage whole screw
7. Most point of using centrifuge is keep bowl running balance,or it will damage very fast,so,check and test balance is necessary after fix or maintencance

Keep checking the equipment is never wrong to make separate well and service longer

GN solids control focus on separation

During the production of oil and gas, water is the most part volume waste stream. Produced liquid may contain dispersed and dissolved hydrocarbons, dissolved organics and dissolved inorganic compounds. In addition, it may also contain a significant amount of suspended solids of different origins (formation, precipitation, corrosion, etc.) and thus, different in nature (sand, clay, carbonates, sulphates, other.).

Before water can be reuse, it must be treated to remove some of the contaminants listed above. Typically, this produced water has been separated from the production stream in multistage separation drums.

If the produced water is to be discharged, dispersed hydrocarbons must be reduced to comply with the environmental regulations of the region. Currently, dispersed oil has been separated by gravitational processes ranging from settling and flotation to deoiling hydrocyclones, and in extreme cases centrifugation.

If the pretreated water is to be discharged into disposal wells or re-injected into the formation, suspended solids need to be reduced to prevent potential blockage of the receiving medium. In this case, oil is removed from the process stream by one or more of the methods mentioned above followed by a desanding step. This desanding has been accomplished with filtration in the past and desanding hydrocyclones more recently. In special cases, solids and oil have been removed in a single step and by deep bed filtration or liquid/solids separate centrifuges. Recently, cross flow membrane filtration has been try ,and get success to solve problem

The gravity settling section normally takes up the main part space in the separator.the size depends upon the physical properties of the fluids being separated, the volume of these fluids, the residence time required to achieve gravity settling, and if or not there are separator internals to assist the gravity separation.

TDU is mainly for hard treatment material,and normally as the last step of whole waste management system

When decided way to treat/manage waste like sludge or slurry,need check contect of material to design economic/fast solution

For example of this material contect:

• 59% Moisture
• 30% Solids
• 11% Oil
• Total Monthly Volume 1500 MT
• 24hr Operation

The liquid content is 59%+11%=70%,percentage is very high,it will waste a lot energy if feed to TDU directly,because TDU’s ability is face to liquid part of material and request high energy cost,if have low cost pretreatment way to reduce mainly liquid part of material,the TDU will focus energy to treat hard removable part of liquid,to raise speed and save cost

GN oil sludge treatment system can collect most part of material,and the cost is not high like TDU,we can use it as pretreatment way for TDU to raise treatment speed and save cost

Also the TDU’s capacity is not big normally,like 3.5-5ton/hour,when material quantity is very high,for raise speed of whole treatment progress,pretreatment will be very important to reduce material quantity,and let TDU treat important liquid part,to reach best efficiency

 

Some pretreatment was will design based on waste management unit, based on different request and quantity
