Before we get a standard API RP13E, screen suppliers use oblong mesh to define the shaker screens, though it is kind of old fashion, but it is still very useful lets see, eg. for Brandt 4x5 shaker, approximately 48-1/4" OCW x 59-1/2", it is still efficient to use B-40 Screen Single Layer (20 x 30 Mesh) (Oblong) 40 to make both user and supplier understand each other.
Oblong is an older brother comparing XR XL and all other rectangular or square holes technology.
XR Mesh is utilized in a unique three-layer arrangement that creates exceptional shale shaker screens. The XR screen design features innovative oblong openings with a greater length-to-width ratio than other rectangular meshes.
It also incorporates wire diameters that are 50 percent larger than comparable meshes.
The large diameter wire is calendared to lock mesh openings securely in place. All three layers are made of finely woven stainless steel. The middle layer increases screen life by acting as a buffer between the fine top mesh and coarse backup layer, as well as serving as a mechanical deblinding agent for the top mesh.
To extend the screen life, bare more capacity, being comply with the API standard, every supplier is developing their own way to make the screens better, that is why we have DX DF HP and so on.
Different screen construction also make the world more attractive.

TBM (Tunnel Boring Machine) is one important part of civil engineering, procedure similar as HDD, but the application, drilling mud charactor, more like bored hole piling. So usually the system or module part for piling desanding can also be used for part of TBM.
TBM Excavation Process
The soil excavation is performed by the cutter head. The excavated materials go through the cutter head into the tunneling machine chamber. There, they are crushed into small parts and mixed into the working fluid, called slurry, which is composed of a mix of bentonite and water. The cutter head is equipped with disk cutters for rocky material and scrapers for soft ground. The excavated material is carried in suspension in the slurry and is pumped to the separation plant located near the shaft. This separation plant shall be composed of vibration shakers, scalping units, hydro-cyclones and centrifuges in order to separate cuttings from the working fluid. After this process, the slurry is pumped back to the TBM to be used again, and the excavated material is loaded into dump trucks.
TBM Mud System in different Capacity
GNMS-500D desander slurry separation system for 120 m³/h Micro TBM
GNMS-1000D Desander slurry separation system for 240 m³/h TBM

Comparing the oil gas drilling project, water well drilling need more flexible rig, also drilling mud system, move often, and need take care more on the environment. Water Wells drilling can vary greatly in depth, water volume, and water quality. Well water typically contains more minerals in solution than surface water and may require treatment to soften the water.
GN Solids Control just exported one unit 200gpm drilling mud system to Kuwait, containing a double deck mud cleaner with 4each 4inch hydrocyclones, also feeding pump and mixing unit. As mentioned to be more flexible, we add a trailer to make it a mobile one.

Same as GN Solids Control, Derrick also is a good solids control equipment supplier, one of their old fashion model is Derrick FC 313M, which is replaced by Derrick FLC 500 series. The mud cleaner, like GNZJ703-1S8N, GNZJ2S12N, GNZJ3S16N, are designed expressly for removing solids from drilling fluid.
This model shaker is designed to be a linear motion, with only one shaker motor, three panel, manually operated, adjustable while drilling (AWD) , which permits angular adjustment of the screen frame between -1° and +5° while the equipment is operating.
The screen frame is a structural component having mounting provisions for the vibrator motor and
screen panels. The screen frame is suspended between the vertical legs of the support frame.
The three screen panels are installed on the bed of the screen frame and held in place by the adjustable under-screen tensioning system.
The dimension of the shaker screens is: 36"x30" (914mmX762mm)
Except all normal or popular derrick 500series screen, derrcik 2000 series screen, GN also supply replacement screens for Derrick 300 series, Derrick 600 series. After start office in Houston, now we get more and more chance to compete with the famous brand like derrick, also get more chances to learn from them, while we will still insist on designing on our own, keep tune to GN products.
