GN designed and produced mud cleaning system can be used for all projects of liquid-solids separation. If only the project is to separate the solids( it could be clay, cutting, silt, bentonite, etc.) out of fluids( it could be water, mud, oil),GN mud cleaning system can be applied. But normally we used it for drilling mud/fluids, for oil & gas drilling, HDD & CBM, geothermal drilling, water well drilling, mining diamond core drilling.

Trailer mounted mud cleaning system is more and more required for convenient transportation from site to site. But skid mounted mud cleaning system which can be loaded into container is also popular because of competitive price, stable performance.

GN mud mixing system is composed of a mud mixing tank, mud hopper and mixing pump and pipelines, valves, stairs, handrails , mud agitator, mud gun, sometimes in the liquid mud plant we put the decanter centrifuge on top of the mixing tank.

The mud mixing unit is also called jet mud mixer, it can be installed on the mud tank for convenient move, also it can be located on the ground and connect with the mixing tank by pipe, so that it can enlarge the storage capacity of the mud tank. You can also put the mud hopper on top of the mud tank or on the skid of the mud tank, the former way can get the best performance, but difficult to add chemical material, you have to lift the material through the stair. The later way is easy to add material, but the mixing effect is not so good as the former one.

Drilling equipments for oilfiled including: (drilling rig complete package)

Mud tank, shale shaker, suction line, mud pump, motor, vibrating hose, draw-works, standpipe, Kelly hose, drill pipe, floor, swivel, Derrick, BOP, drill bit, drill string, flow line, wellhead, Kelly drive…,etc.

GN Solids control produce mud tank, shale shaker and other solids control equipments, we already exported these equipments to over 60 countries in the world, we also develop drilling waste management equipments which is also used for rig site. Usually they are installed after the solids control system for further treatment of the cuttings separated from the solids control system.

GN manufacture drilling mud system for oilfield drilling, HDD, geothermal, water well, gas drilling, CBM, dredging slurry separation, piling, TBM, etc. GN produced drilling mud system are with compact design, good performance (usually other supplier only install desilter cone after shale shaker, but GN install both desander cone and desilter cone) and competitive price.

GN also cooperated with other mud tank suppliers to provide only solids control equipments, if you are a mud tank supplier and looking for shale shaker, mud cleaner, decanter centrifuge, pls contact GN solids control, we also provide mud agitator and centrifugal pump in stock.

The demand of drill cutting storage tank is increasing more and more. In the oil drilling industry a growing problem is the storage and transportation of oil contaminated drill cuttings that are required to be removed from a drilling installation and transported to a disposal facility both in onshore and offshore operations. In zero discharge system, drill cuttings and associated waste fluids are collected on the rig in cuttings boxes, then sent to shore for disposal or treatment prior to disposal.

Except for drill cutting storage tank, GN also produced diesel tank, water storage tank, mud storage tank, chemical tank, etc.

Mud tank is the necessary components in a complete mud system, there are shale shaker, desander, desilter, centrifugal pumps, mud agitator, mud gun on the mud system tank. The main components for the tank including hammer unions, butterfly valve, gate valve, flexible connection hose, clean gate, pipelines, lights, electric control system, hand rails, walkway, stairs, man hole and solids control equipments. Above are the main mud system tank components, sometimes there are some other components, like mud hopper, mixing pump, sun-proof cover, mud gas separator, vacuum degasser.

The mud tank needs 2 types of unions, including hammer union and air union, air union is also called pneumatic union, since GN do not use such union in the mud tank design, we would like to introduce hammer union mainly. Hammer unions are one of the most common “quick connection” methods used in the oilfield for joining together components in a temporary pipe work system. Drilling mud fluid systems connecting the steel tanks to the pumps need leak proof and quickly detachable connections for large diameter pipe 4” to 16”.

Working principle of poor boy degasser

Poor boy degasser is also called liquid-mud separator, it Is a pressure vessel in a fixed vertical position, inside is a defensive pipe against sprinkler. When contaminated mud is routed into the separator, it flows to the sprinkler, then spread to the defensive guard pipe, during this process, the head of entrained gases “break out”. The released gas then carried by the vent lines to remote location where it can be safely flared. The flow of liquid from the vessel can be regulated by a liquid-level-control valve or a U-tube, ensuring adequate retention time in the separator for the gas to break out.

Mud tank cleaning

After using the mud tank for a long time, there will be precipitation of solids and silts, even though we have a lot of solutions to less the precipitation, e.g. each tank should design several cleaning gate which is closed to the bottom, after several months, you can clean the tank bottom through the cleaning gate. Also we can design the tank bottom to round type, not level, it is easy to clean the tank. Most of the tank is designed with water line, which can be used to clean the tank top and tank bottom.

Even though there are a lot of ways to less the solids, you still need special equipments for the mud tank cleaning

. Firstly used a submersible slurry pump or centrifugal pump to transfer the slurry to the cleaning system, which is composed of shale shaker, desander, desilter, sometimes also with decanter centrifuge. The waste water can be re-used to clean the tank, the waste solids can be disposal or to the dewatering system for future process.
