GN designed and produced oil drilling solids control system and drilling mud recycling system have been operated in the rig sites of 60 countries in the world, including Cuba. Estimates of total oil reserves in Cuba are varied, and depend mainly on estimations of undiscovered offshore deposits in the North Cuba Basin. Fearing an oil spill in Cuban waters, U.S. officials have forged a bond with the Castro regime to preserve the threatened marine ecosystem that connects the island nation to the Florida coast.

Below photos showed the workover rig solids control system used in Cuba: It including one set of XJ450 workover rig solids control system and one set of XJ650 workover rig mud recycling system. The main configurations are as below:

XJ450 workover rig solids control system:

2 units of mud tanks with mud agitators, mud guns, hoppers

1 set of mud gas separator

1 unit of water tank

1 unit of waste collection box

XJ650 workover rig mud recycling system:

2 units of mud tanks with mud agitators, mud guns, hoppers and shale shaker GNZS703E-HB

1 unit of diesel tank

1 unit of water tank

1 unit of fuel tank

1 unit of waste collection box

1 set of mud gas separator

The main features of these mud tanks are not traditional Rectangle tank, but V-bottom tank for easy cleaning of solids. Except for such design, we can also provide customized design tank like round bottom tank for easy cleaning, trailer/wheel mounted mud tank for easy transportation, and 3-runner oilfield standard design mud tanks. The mud tanks qty and total system volume can be also customized. If only the end-user have such special requirement, we will try our best to provide the best solution for your rigsite.

Pls contact either GN solids control or GN solids America for a customized proposal.

Mud tank is the base for mud system, all the solids control equipment should be mounted on mud tank for operation. We have large quantity of mud tank sales in domestic market; for overseas market, we recommend customer do it locally to avoid pretty high freight cost. However, there are still some customers from Middle East and Africa bought mud tanks from us due to instable of local political issues.

Recently, we ship one mud tank with mud agitators, mud guns to Iraq. The customer is locally oil service company with many years industrial experience. The mud tank will be used as drilling mud storage tank.

Why we should have drill slurry storaged? Mainly it is because of the reasons below:

(1)   Requirement for the carriage and storage of mud on mobile drilling units has increased over the years, it is not convenient to process the drilling mud at the platform, you have to collect the used drill slurry and carry it to drilling fluids plant for process, then recycle the clean drill slurry and disposal the useless cuttings, so that it will not influence the environment.

Drill Slurry Storage

(2)   Clean drill slurry should be storaged for use, for drilling , for mixing , for lubricate the drill bit.

(3)   Useless drill cuttings should be collected and storage, then carried to drilling waste management system for process.

GN solids control manufacture drill slurry storage tank for various application, with necessary mud agitators, mud gun, centrifugal pump and mixing hopper. We can produce mud storage tank together with solids control system or separately. Compared with shaker tank and intermediate tank, the pipeline of storage tank is much simple, if required by the clients, we will divide it into several compartment by clapboard. Sometimes mud ditch is installed on each compartment. Handrails, stairs, cleaning gate, valves are included, but walkways are not included. There is flexible hose connected 2 tanks.

Mud guns are meant to provide supplemental or primary mixing in mud tanks depending on the number being used and the pit size. They are best used in tank corners to keep solids from settling and a mud agitator is placed in the tank center.

How to operate the mud gun?

A. Safty information

TURN OFF. LOCK OUT, and TAG OUT the electrical power supply to the pumps feeding the mud guns before servicing.

Inspect the unit regularly, and replace damaged or worn components only with parts supplied by the original equipment manufacturer.

Before entering a mud tank for any reason, the mud agitators should be locked out and tagged out.

B. General maintenance

1. Grease the swivel once a week. Add (2) shots of a multipurpose NLGI no 2 grease.

2. Visually inspect the mud gun assembly for any leaks, loose fittings once a week. Repair as required.

3. Inspect mud gun jet nozzle for excessive wear. The nozzle has a 5/8” bore when new. The nozzle should be changed when the bore is 7/8” or higher. This should be done once a month.

Once installation is complete, the unit can be started by turning the feed pump on. The direction of discharge may be modified to suit the operators requirements by rotating the swivel.

GN solids control mud system can be used for both oil & gas drilling and water well drilling. Water wellis an excavation or structure created in the ground by drilling to access groundwater in underground aquifers. Most shallow well drilling machines are mounted on large trucks, trailers, or tracked vehicle carriages. Water wells typically range from 3 to 18 m deep, but in some areas can go deeper than 900 m.

GN200gpm trailer mounted mud system for water well drilling

Most of the water well drilling rig is trailer mounted or truck mounted, for convenient transportation from one place to another. Some contractors do not process the used mud from water well drilling, but recently there are more strict laws for environment protection, they have to search for small mud recycling system to complete the job. They prefer trailer mounted mud system, GN 200gpm trailer mounted mud recycling system is widely used for water well drilling. Total transportation dimension is 5500x2300x4000mm( including the trailer height), it meets the transportation limit in most of the countries in the world( you do not need to remove anything when transport in domestic). You only need to remove the mud cleaner and shale shaker from the tank, then I can fit for 40feet standard container.

GN solids control manufacture 2” mud gun and 3” mud gun, and we have several sets of mud guns in stock.

There are 2 type of mud guns, the common one is top tank type, sometimes we design it as bottom tank type. Top tank mud gun is controlled by staff on the tank, the difference between GN mud gun and NOV mud gun is the nozzle numbers, we make to 3 nozzle numbers, which can jet more place in the tank so the agitating effect can be better.

What is the difference between tank top and tank bottom mud gun?1 tank top mud gun

 Tank top mud gun is usually with function of agitating, together with mud agitator, they are important equipments for drilling mud tank and mud mixing tank. And how many sets of agitator you have for the mud mixing tank, usually how many mud guns you have. But it also have exception, for example, when the tank room is very small, you have no room for the agitator, and the tank is not so large, you can use a mud gun instead, it is much cheaper, needs smaller area to install and convenient to operate, also do not need to use electric power, but use pressure to work, and you do not need to buy a lot of spare parts such as gear box, bearings for the mud agitator. Anyway mud gun has a lot of advantages but it can not replace mud agitator totally, the agitating effect is not so strong as agitator. We need to use them together to benefit from both of them.

2 Tank bottom mud gun

Tank bottom mud gun also called inner tank mud gun, its function usually not agitating, but transferring and mixing line. It transfers the mud from mud mixing tank to another tank.

Where is the pressure come from ?

For high pressure mud gun, the pressure came from mud pump, for lower pressure mud gun, the pressure came from mixing pump, it can mix and transfer drilling mud to another tank.
