Solids Control systems and equipment are quite important for a successful drilling project. An efficient solids control system can helps to remove solids particles out of the drilling mud. In this way, the expensive drilling mud could be reused in future drilling. What is included in a complete solids control system?

A complete solids control system, especially for a large power horse drilling rig, should have following equipment divided per tanks:

1. The trip tank. Per certain rig size, there should be a certain amount of drilling mud to be prepared, but during drilling, there is always some mud loss because of drilling or because of mud separation. So there should be a trip tank holding well prepared mud for compensate the mud loss. For the trip tank, there is always a mud agitator and a centrifugal pump as trip pump.

2. Settle tank or also called the shaker tank. Shale shakers are the first step separation of the solids control system, they are used to remove the most solids from the drilling mud with suitable vibrating G force and screen mesh. On a long shaker tank, after the shale shakers, there should be a degasser to remove the bubbles generated during drilling to ensure the safety and to protect the pumps in following steps. If there is a mud cleaner in this system, it should be on this tank, too. A mud cleaner is a combination of desanding cones and desilter cones fed by centrifugal pumps.

3. Active tank. It is a tank for decanter centrifuge. The decanter centrifuge is located after the mud cleaner, to do the barite recovery or fine particle separation. It is always fed by a submersible slurry pump or a screw pump

4. Suction tank for mixing and reserve tank for storage.

Pipe jacking is one kind of drilling works similar as Tunnel Bored projects, which need a pipe jacking machine to drill under the ground and the slurries generated from drilling shall be treated well before disposal.

For such projects, like for TBM projects, GN Solids Control has several optional solutions, including following:

1. An economic and compact mud unit GNMS-D series desanding units. This series are made of a double deck shaker and a desanding/desilter section and a catch tank. They have 2 steps for separation. A feeding pump is located on side of catch tank. It is flexible for its compact layout. GN has various capacities among 200GPM, 500GPM, 1000GPM and 1500GPM.

2. Self-contained mud systems GNMS-B series including a similar double deck shaker as the GNMS-D series including shaker and cyclones and cyclone feeding pump, and also a larger tank plus a mud mixing hopper. It can serve 2 functions: 2 step separation and mud mixing. It also ranges from 200GPM to 1000GPM.

3. GNTBM series slurry plant, as this client purchased from GN. They have 3 steps separation, shale shaker, desander and desilter, equipped by 2 large slurry pumps for feeding, and a compact design with 2 layers. There are 3 models for option, the 240cbm/hr, 360cbm/hr and 500cbm/hr, especially for the TMB projects.

Those above 3 kinds of mud recycling units are widely used in many countries, clients and end users are buying from GN directly, and also, lots of Chinese contractors are bringing GN’s equipment to all over the world. They are happy with the good performance and reliable service from GN professional team.

Considering the environment protection purpose and also the less consumption of drilling mud, there is always necessary for the HDD contractors to buy in reclaimers to be used together with their drilling rigs to recycle the drilling fluids and also reduce the transportation volume of solids discharges. GN Solids Control has been one of the most famous brands for providing such solutions for years. In the October or this year, GN Solids Control just fabricated a kind of customized mud reclaimer set to an international HDD contractor.

1. Why choose GN Solids Control?
GN Solids Control was established since year 2007 and ever since its establishment, it has been participating in the drilling mud separation projects for HDD contractors. Based on clients’ request, GN Solids Control has designed and made hundreds of systems. Cause a big proportion of GN’s equipment has been used for oil and gas industry and GN Solids Control has become the 1st API Certified solids control brand in China. GN applies the same standards for the HDD equipment as the oil and gas industries. GN always focuses on the high quality and reliable service.

2. What does GN Solids Control make for the HDD mud recycling?
GN Solids Control has several standards models for HDD mud reclaimers, with various treating capacities. Such reclaimers are equipped by a lower deck shaker, desanding or desilter cones, a catch tank and feeding pump for cyclones. They are compact in foot print and on their sides, there is always a mud mixing unit for mixing and prepare the mud.
Besides such compact reclaimers, GN Solids Control also has bigger solutions, with larger storage capacity mud tanks and also include in a mud mixing hopper and mixing pumps. They are easy for transportation on land and also in container.

WEFTEC 2021 was successfully held in America and it attracted quite a lot professional visitors. Among water treatment, an efficient separation is non-doubt an important procedure. GN Solids America has participated in the exhibition and brought to the event 2 compact but handy machines: GNLW224ET decanter centrifuge and GNSP-20B vacuum pump.

GNLW is the model GN Solids Control and GN Solids America name their decanter centrifuges, they are 2 phase decanter centrifuges designed with high speed rotation ability. In the code GNLW224, 22 shows the bowl diameter which is 22 inch and the 4 means the bowl length and diameter ratio. The 4 ratio is larger than 3. For each centrifuge size, GN has both 3 and 4 available. Among the whole GN centrifuge models, there are GNLW363 and GNLW364 decanter centrifuge with 14 inch diameter bowls, GNLW452, GNLW453 and GNLW454 with 18 inch bowl diameter, GNLW553 and GNLW554 with 18 inch bowl and GNLW764 with 30 inch huge bowl.

GNSP-20P is a middle sized vacuum pump. Vacuum pump is also called solids pump because of its high ability for allowing large particles. Unless other pumps, the solids pumps can handle even dry material like sand and small stones. The only size limit is the pipeline size. And by using only compressed air as driven force, those vacuum pumps don’t need electricity. They can be used in Explosive Proof conditions for CNEX, IECEX and ATEX. There are mainly 3 models of GNSP vacuum pumps, the largest one is GNSP-40B with capacity 40cbm per hour, and the other 2 models are respectively 20 cbm per hour and 10 cbm per hour, the 2 smaller models are equipped by wheels for flexible use.

GN Solids America is located in Houston, TX in USA, with warehouse and stock for main equipment. Welcome to visit GN Team there.
