More Shaker Screens for HDD Project in USA

Trenchless business is still growing, though the economy is not aiding, the projects need proceed and keep going. There is once a client comes to our yard, and thumbs up, saying this is a good supplier, then our answer is good suppliers supported by good customers. Very appreciate all the hard work our clients have been doing, and their feedback to improve our products.

After GN hade the branch in Houston, more and more clients comes to our shop and know more about us, then more and more business come along. Shaker screens are the one of the consumable products in drilling projects, not only oil gas drilling, though that consume more, so does HDD.

GN mainly manufactures the composite frame shaker screen currently. Steel bone inside with plastic covered outside, GN composite frame shaker screen performs much better than the steel frame shaker screen. During the running, the composite shaker screen will be much stronger as fiber glass is added into the fabrication material. When come into storage, the composite frame shaker screen will last for longer time as it will not rust. GN shaker screen bone frame is welded by robot to ensure the consistency.

Among all Chinese solids control brands, GN solids control is the only one who makes both solids control equipment and the shaker screen, and the only one shaker screen manufacturer who tested the shaker screen as perAPI RP 13C standard and got the report proving GN full series screen API numbers are comply with the standard.. All manufacturing procedures of GN shaker screen are processed in GN own factory from bone frame welding, wire mesh cutting to heating and pressing, plastic covering. GN is able to control all procedures to ensure the quality.

ViST Unit to Europe for Mongoose Shaker

With help of our partner in Romania, AEGEAN OIL CONSULTING SRL, now we get another ViST unit for an European company.

Before the ViST comes to the market, GN have sent the ViST to an offshore site to test, the client actually are testing a few options, and finally satisfied with GN equipment result. And then we got 6 sets ViST to the site.Though the principle is simple, the shale shaker have been developed, in many different generations, due to the limited area, the mud recycling equipment on offshore platform is always with compact structure and high efficiency. The used drilling mud and waste cuttings coming from offshore platform normally will be barged to land for treatment. Thus, to maximally recover the drilling fluids will greatly reduce the time and fund cost in treating the waste cuttings. GN VIST vacuum shale shaker can greatly increase the volume of recovered drilling fluids.

Features of ViST Vacuum Shale Shaker

1. GN Vist vacuum shale shaker is suitable for OBM, WBM and SBM.

2. By using the VIST system, the drilling fluids recovered will be increased by 30%~50%, It greatly reduces the discharge of drilling waste and the cost in transporting the waste.

3. Before this VIST shale shaker, GN ever issued the high G force drying shaker to recover more drilling fluids on cuttings. By using this VIST system, the drying shaker will be no need; Moreover, the installation of VIST system will not need any extra area onsite.

4. Operator can put much finer shaker screen on the shale shaker as the ViST vacuum system increased the liquid conductance of the screen.

Containerized Systems from GN to the World

GN have been working a lot on how to modularize the whole system, for different applications, dispite all the customizations, there is always one solution which seems very popular, containerize. Though different people get different understanding on the containerize, either put into container to save shipping cost, or make itself as container size, to save all hassles afterwards. 

Recently we delivered two containerized systems, one is for HDD, the other is for OST.

This HDD mud recycling system is a high configuration including all 4 stages separation equipment. Below is the list of this system. 1. Shale shaker GNZS703F is the first stage separation equipment to remove the coarse solids. GNZS03F is the latest version shale shaker in GN production line. This model shale shaker is with 3 panel composite frame shaker screen that is fastened by using ratchet spanner, easily and fast.2. GNZJ703F-1S8N mud cleaner is combination unit of desander and desilter. The mud cleaner under shaker is the same model GNZS703F. Normally, GN use same model shale shaker for easy future maintenance. 2 units centrifugal pump are equipped in the system for feeding the drilling mud to the hydrocyclone units for smaller sand and silt separation. 3. Shale shaker and mud cleaner are firstly fixed on a strong steel frame. The frame bottom is same dimension with the under located mud tank. This frame can be lifted easily with shaker and mud cleaner installed on it for easy assembling and transportation.

4. Decanter centrifuge GNLW363C-VFD is last stage separation equipment for fine solids separation. After several time recycling, there will be much fine solids in the drilling mud. The centrifuge is used to remove the fine solids to ensure the property of the drilling mud. Decanter centrifuge is fixed on a collecting tank with 4 supporting legs. Liquid is flow into the tank and solids will be collected by the screw conveyor and transferred out of the system.

This containerized oil sludge treatment system is consisting of below modules:1. Premixing Module – per customer requirement, GN provided the sludge vacuum pump to transfer the oil sludge from the collection pit to the system. Two tanks equipped with agitators and heating line are used as the premixing vessel.2. Coarse Screen Module – the washed sludge will be pumped to the coarse shaker screen for large size solid particles separation. A flushing pipe is installed over the shaker deck to spray washing the sludge. For warm consideration, the shaker unit is put in a container, and the complete container will be put on a collecting tank to store the treated slurry.3. Fine Solids Separation Module – slurry treated by the shaker will be pumped to the decanter centrifuge for fine solids separation. For easy collection of the solids discharged from the centrifuge, the centrifuge is supported by a skid and a screw conveyor is installed under the centrifuge solids discharge port. 4. 3 Phase Separation Skid Module – The slurry out of the decanter will flow into the 3 phase separation module that includes inclined plate clarifier, oil water separator and surge tanks for separated oil and water. The 3 phase separation module is the last process procedure of the oil sludge separation system.5. Chemical Dosing Module – the chemicals can be added into each procedure of the system. The dosing system is also installed in a container and connected to each procedure via pipes and valves. GN is able to provide the oil sludge system with customized color and client’s logo for better advertisement of client’s business. Please feel free to contact with GN for more separation solutions.

All the the tanks, frames can be designed to meet the specific requirement from site. freely get in touch with GN for your detail requirement.

Oil Sludge Treatment System to Europe Client

Oil sludge now has been a more and more serious issue, many different sources, different backgrounds, but normally what we are facing is either a farm collecting oil sludge, or a pit, where was collecting the oilly sludge. On our site, we saw drill rigs, we saw the beam pumping machines, and we understand where these sludge comes. After checked the site many times, and experience from other area in the world, the client developed this system with GN, and keep giving GN more and more info to help GN improve the system and equipment. This containerized oil sludge treatment system is consisting of below modules: 1. Premixing Module – per customer requirement, GN provided the sludge vacuum pump to transfer the oil sludge from the collection pit to the system.

Oil Sludge Treatment System to American Client

Oil sludge now has been a more and more serious issue, many different sources, different backgrounds, but normally what we are facing is either a farm collecting oil sludge, or a pit, where was collecting the oilly sludge. It is not a new technology, but we have a special machine, we need your equipment to do the separation together. This client is offering service, with a full package of equipment, to separate the oil / water / solids step by step. The ordered oil sludge treatment system is GN 2 cubic meters per hour model. Client is going to use this system as a demo to verify it is workable in recovering the oil from oil sludge. Actually, the excellent performance of GN oil sludge treatment system has been proved onsite. In this system, client plan to bring their SMO (shear, mixing and oxidation) unit to connect with GN oil sludge system for better demulsification performance. The system includs a premixing module, a classify system, then down to a shaker modular, decanter module, then to last step disc stac. While as we all know the mixture always goes to 3section, water / oil / solids, though it is not clearly just doing this, it is in one way or the other separating by themselves, or in each and every step, it is doing the same thing, then the whole flow changes.  GN has another oil sludge treatment system with capacity of 15 cubic meters per hours is almost done, now is the final assembly procedure. And we are upgrading the DEMO system, to make it more suitable for different applications, then it will be easier in future to have our system to the site to do some real test.
