We have found the following label on screens on desiler unit:

120 mesh

GN Solids Control

Size 900x750 mm

We did not find any labels or signs on screens on the shale shaker so we are not sure what is there. Please check at your engineering department and maybe they will confirm to you. Questions:

- what API number is for 120 mesh screens?

- What API number is for 40 mesh screen?

Please comment what does it mean 120 mesh?

If this is 120 mesh, what is API number for these screens and what is D100 separation value (in microns)? Please comment. Actually according our technology, following derrick wiring tech, normally 40mesh is API40, 120mesh is API120, unless different screening technology is required, can not always reverse.

Pls refer our brochure here http://gnshakerscreen.com/images/GN%20Shaker%20Screen.pdf and derrcik screen brochure. We ordered two different types of screens and received all screens the same (API 40, 394 microns). Please comment why we received not the same screens as ordered by our company.

And please be so kind and comment what does it mean API 40? If API 40, so what is a value of mesh ? http://www.halliburton.com/public/bar/contents/data_sheets/web/sales_data_sheets/sds-048.pdf This might be a good link for you, D100 to API in page2. This API40, 394 microns, between 40~50mesh, take it 45mesh, http://www.showmegold.org/news/Mesh.htm 

I have reached a very exciting stage in the project I have been working on for two and a half years. After 12 months of build I finally have a rig I can start promoting.

My rig is purpose built for the Australian CSG industry, but may also have applications in doing cheaper top hole section drilling on oil and shale projects in Australia. She is design for rapid mobilization with minimal environmental impact. It also incorporates all safety features expected in modern drilling rigs, such as enclosed driller cabins and hands free drilling operations. How ever the rig is still a simple, robust design, where I have intentionally avoided the use of computer or PLC control systems to keep maintenance costs to a minimum.   

CMD220 Unconventional Gas Drilling Rig.
 
·         100 Metric Tonne (220,400 lbs.) Pull Back
·         Telescoping Hydraulic Mast
·         24,750 Nm (18,255 ft/lbs.) Torque
·         Range III Tubulars
 
The CMD220 is a competitively priced, custom designed rig that has been built for the Australian market. This rig has been designed from the ground up to exceed international standards and comply with Australian requirements and legislation.
 
The CMD220 project is a Joint Venture between Cortech Drilling Equipment Co. (China) and GasDrill International (Singapore). Technical and service and support will be provided by Oztec Manufacturing of Toowoomba, Queensland (Australia).     
 
Australian compliance engineers have been thoroughly involved to ensure that the CMD220 meets ADR requirements at every stage , from design all of the way  through the factory build, and including the  commissioning.
 
Independant test labs have commissioned for the build period to ensure the quality control and certification of all welds and lifting equipment.
 
Moduspec are assisting with the build schedule and have planned factory visits for crucial stages of the build to ensure the rig will pass their auditing system.
 
The factory has applied to the American Petroleum Institute (API) and is currently being audited for API Monogram and Specification 4F certification. We expect to have Certification the end of 2014.
 
Australian Engineers from RYCO Hydraulics have assisted in the design of the hydraulic system and have carried out audits to ensure that RYCO hoses and fittings are installed to comply with the Australian Mining Standards MDG-41 and MDG-15.
 
The CMD220 comes as an easily transportable trailer mounted package. Great care was taken in the design stage to ensure that the rig is compliant to travel on Australian roads without the need for escort vehicles. The rig will be permitted to move on Australian Roads on a one off “Period Permit” lasting up to six months.
 
The CMD220 is of a simple design compared to other rigs of comparable size.  The CMD220 is fitted with a pivoting Top Drive and tubular handling equipment built into the BOP Sub Base Structure.
The unit is self-erecting to a work height of 3.5m without the need of auxiliary Pony Bases.
The CMD220 is ideally suited for shallow gas, surface hole, CBM, directional and large diameter drilling applications with mud or air.
 
We are aiming to have the first rig landed in Toowoomba by the end of 2014.

We are a drilling company, most of our holes are wireline to 200m. We have been using another brand which are very large and cumbersome . I am looking at alternatives as a lot of our sites are very small.
We use a maximum of 200 litres a minite but normally less. I have a sand guzzler pump pumping from hole or alternatively can use a trash pump which pumps 700 litres a minute. Most of our mud is fine clay particles and sand. I was looking at need a shale shaker also after desander but will wait to see how it works out. I also have a 100 micron filter bag which mud will pumped to after desander, which is a temporary measure.

Here is the situation from one client, small drilling project, but commit themselves to save and protect the environment, just like the beauty and the geek, you need find a good match, though you may like Kingkong's love story.

Glad to invite you to check our brochures, then we can go through:
1. Pls check page 1, usually solids control means 4steps, shale shaker first, desander seond, desilter third, decanter centrifuge fourth; and below each equipment, mentioned cut point, shale shaker is separating particles bigger than 100 microns; depends on the screens we use though.
2. The desander 1ea capacity upto 500gpm. Why not desilter? If you have sand, big particles may plug the desilter nozzle.
3. Pls refer to the big system decription, drawing and flowline; which may helps. You will not need this big one, contact George for a digital copy.
4. We'd recommend you only use a shale shaker GNZS752E-DM; Which is similar as one of our diamond drilling project in PNG. We are using one shale shaker, one decanter centrifuge.
