  • 1) 1ea shale shaker, equipped with 3panel shaker screen, treating capacity 120m3/h for light mud or water treatment.
  • 2) 2ea mud agitator, to mixing the mud and suspending the heavy mud to avoid settlement.
  • 3) 1ea mixing hopper, to mixing bentonite or barite
  • 4) 1ea centrifugal pump, to give mixing power for the mixing hopper. Can also work to transfer the mud out when the mixing hopper stop work.
  • 5) 1ea mud tank with 9m in length, 2.2m in width and 2.2m in height. This design mud tank can be put into container for shipment, easier transportation and much better sea freight cost.

All above item is installed on the mud tank, and the mud system can working well for drilling rigs & mud pumps.

500gpm mud system for another client. The water well drilling depth is deeper to 1000m. The client rig is from Drillmec, and he need 3 stage treatment mud system. And we offer mud system with equipment list below:

  • 1) 1ea shale shaker, equipped with 3panel shaker screen, treating capacity 120m3/h for light mud or water treatment.
  • 2) 1ea mud cleaner, equipped with 3 panel shaker & 1ea 10inch desander cones & 8ea 4inch desilter cones. The mud cleaner require 2sets 45kw centrifugal pump for feeding the cones.
  • 3) Mixing hopper, mixing pump, trailer mounted tanks is equipped for the system.

We normally customize mud system for client, if you need any support, pls contact GN Solids Control.

Good news ! We are awarded another purchase order from Middle East HDD client. The client is local biggest horizontal directional drilling private company, and just wins contracts from government gas dept. They need more HDD rigs, HDD mud equipment to continue the project.

160629 tandem shale shaker 2

We have offered several times quotation in last year, including:

1) Double deck shale shaker with coarse steel screen.

The client need double deck shaker, up deck 2mm shaker screen to remove all stones, down deck 0.5mm shaker screen to remove fine solids. The client don’t like carbon steel screen, and require PU material screen for longer lifetime.

We have rich experience in double deck linear motion shale shaker manufacturing, as well as PU material shaker screen. We have confidence the client give issue repeated order if they need more.

2)  Assembly unit with desander cones and desilter cones

The client don’t need the mud cleaner, three in one unit which include desander cones, desilter cones and down deck shaker. Instead, he require assembly unit with desander and desilter cones.  This is good to save footprint in mud tanks, and also lower down the unit price, spare parts cost.

We customize the assembly unit as per the request from client.

3) 3ea centrifugal pump

2ea centrifugal pump feed to the assembly unit of desander cones and desilter cones. 1ea centrifugal pump as backup. Or will be used in other application.

4) Economic standard mud system

As the client have different project, and they also need one compact mud system, economic standard, GNMS-500D. This unit is generally used for piling project, 2 stage separation with screen / desander cones, to remove the big solids.

We also have other capacity for option, including 200gpm GNMS-200D, 500gpm GNMS-500D, 1000gpm GNMS-1000D.If the client project require better fine solids removal, may require higher standard mud system with 4 phase separation. We can offer the turnkey solution per client’s request.

With oil price going up, we just receive tender Invitation from Africa Client, even we don’t participate in overseas tender directly, we can share the news and this maybe a signal of local requirements is arising. The tender on solids control package including below parts;

  1. Provision of Secondary Mud Recovery/Cuttings Dryer (either vertical or horizontal) with feed pump capable of obtaining less than 5% (50gm/kg) cuttings oil retention (COR).

GN response: all GN Vertical cuttings dryer are high standard equipment, which is equivalent to Swaco vertical cuttings dryer / CSI cuttings dryer. GN vertical cuttings dryer are working in many drilling rig site and show high performance.

GNCD930 series cuttings dryer have been working for Oil based mud cuttings treatment over 3 years, the OOC can be reduced to below 5%.

2015.12.02_vertical_cuttings_dryer

  1. Provision of Low and High speed centrifuges with feed pumps for drilling fluids solids control to assist in obtaining less than 5% COR. The units shall have independent bowl and scroll speeds for processing the synthetic base fluid.

GN response: we can offer fixed speed low speed centrifuge / fixed speed high speed centrifuge. And we can offer variable speed centrifuge with PLC control panel, the client can get different speed for different application, much convenient for speed adjustment.

GNLW363CG premium centrifuge is the most popular model, the 14inch centrifuge is equivalent to Derrick DE1000 centrifuge or Swaco 518 centrifuges, much more cost-effective than US brand centrifuges.

Slurry pump is heavy-duty constructed centrifugal pumps which  is able to deal tough and abrasive duties.  The term slurry pumps is consider a generic term, to separate from other type centrifugal pump, this one mainly use to intended for clear liquids.

Many industries usage of slurry pumps are used to keep liquid and solids in mix with large spectrum of usage, such as  mine drainage, dredging of setting lagoons and pumping of drilling mud.  Slurry pump purpose can be pump the medium where abrasive particles are available.  It also transport as much solids as possible, hydraulically.  It pumps the final product in the process.  Many industrial segment use this pump like iron and steel, power generation, paper industry, oil and gas, wastewater treatment, mining, process mineral and other few.

slurry pump

Submersible Slurry Pump have a very simple structure design to ensure maximum performance, minimum energy consumption, long operating life and minimum maintenance.  Many different designs can suit various transportation needs in process application of grinding circuits, hydrocyclone feed and slurry transfer.

Vertical slurry pumps is what GN Solids Control manufacture  as part of solids control system.  This kind of pump can be identify in two kinds, the tank pump and Cantilever/sump pumps.  The tank pump is consider as dry installed pumps and the sump is incorporated in the pump. It opens inlet to prevent air blocking and operate smoothly.  The cantilever structure is single stage and suction with housing bearing, supporting the intermediate pipe connect it to pump’s hydraulic components.  The water is exit out from the drainage .  The impeller is for semi-shrouded with the agitating  vane on the extend.  The main point on this pump is underwater shaft part contain enough rigidity, the impeller and pump should not have bearing and seal so it can be deliver greater medium of the solids cutting.

GN Solids Control can also supply shaker screen, if you need more information pls contact us.

Mud tank is the base for mud system, all the solids control equipment should be mounted on mud tank for operation. We have large quantity of mud tank sales in domestic market; for overseas market, we recommend customer do it locally to avoid pretty high freight cost. However, there are still some customers from Middle East and Africa bought mud tanks from us due to instable of local political issues.

Recently, we ship one mud tank with mud agitators, mud guns to Iraq. The customer is locally oil service company with many years industrial experience. The mud tank will be used as drilling mud storage tank.

What is slurry pump?

A Slurry pump is a type of centrifugal pump in physics principle that increases the pressure of liquid and solid particle mixture, through centrifugal force (a rotating impeller) and converts electrical energy into slurry potential and kinetic energy.

slurry pump

slurry pump

There are 2 kinds of slurry pump, horizontal type and vertical type, for vertical type pump, there are submersible slurry pump and underwater pump. Submersible slurry pump is widely used for drilling fluids transferring, underwater pump is used for fluids transfer. Horizontal slurry pump is also used for drilling slurry transfer, just the installation method is different to meet different mud tank size.

What is vertical slurry pump?

Vertical slurry Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi-shrouded with the agitating vane on the vane extended, the main characteristic of this pump is the underwater pump shaft parts have enough rigidity, the impeller and pump shell have no bearings, no shaft seal, which can transport the greater medium of solid particles. The length of inserting the water by pump is between 800 and 2000, the suction pipe can be matched in case of need. Continue reading »
