A drilling mud mixing system is quite popular in drilling mud systems for both oil and gas drilling and other drilling works like HDD and etc, because during drilling there is always loss of bentonite and other necessary chemicals to the drilling fluids, in order to keep the drilling fluids to be suitable for drilling, such components have to be added into the drilling fluids in time. A mud mixing system is also needed in a mud plant, where the used mud should be re-treated and prepared for future use.

A complete mud mixing system should contain following equipment:

1. A mud mixing hopper, which is a venture hopper. It is mainly used for input the bentonite. GN has 2 models of mud mixing hoppers, the bigger model GNSLDSB uses 40mm nozzle and inlet and outlet of 6 inch, while the smaller model GNSLDMB uses 20mm nozzle and inlet and outlet of 4 inch. They could be linked to GNSB series centrifugal pumps to combine a complete mud mixing unit.

2. A centrifugal pump. GNSB series centrifugal pumps are one of GN popular products. They are fully interchangeable with Magnum pumps even in small parts. GN has centrifugal pumps from 7.5kw to 75kw, with capacity ranging from 35cbm/hr to 320cbm/hr. They could be suitable for most drilling works covering both oil and gas drilling, HDD projects and some TBM’s.

3. QTY of mud mixing hopper and mud mixing pumps depends on the jobsite condition and the consideration of the end user. Normally, in a continuous working project of a large project, clients always prefer a dual hopper design with parallel centrifugal pumps. Hoppers could be one under use and the other back up, so are the pumps. By connected pipelines, either hopper can be linked to either pump to mix liquid from any tank. Comparing with centrifugal pumps, the hoppers are less consumable, that’s why it is not so common to use dual hoppers. Some clients prefer double pump with single hopper. And most popular model is single pump plus hopper.

Last month, GN Solids Control has delivered a liquid mud plant with totally 7500BBL volume to a client from South America. A mud plant is a place used for prepare the drilling mud for drilling rigs, it could be regarded as a mud station. In some mud plant, the used mud can be also treated then returned to solids control system. 7500BBL mud plant is not a small one.

This liquid mud plant manufactured by GN Solids Control is combined by following sections:

1. Mud mixing tank with agitators. This tank is used for prepare the drilling mud by adding useful chemicals into it through a mud mixing hopper. This mud mixing tank also has a storage capacity of 7500BBL.

2. Mud mixing hopper and mud mixing pump. In practice, a mud mixing hopper and a mud mixing pump could be regarded as a integrate mud mixing unit, which can be located on a mud mixing tank or separately besides and mud mixing tank. The end user can choose parallel hoppers together and 2 centrifugal pumps to be linked in parallel. Either pump could serve for either hopper, one for use, the other back up.

3. Vertical mud storage tanks, totally 14 sets, each with 500BBL volume. In order to save space, those storage tanks are made in cylinder shape vertically. All tanks are equipped with level meter to show the mud volume inside. By well-designed pipelines, pump from outside those tanks can suck mud from each tank.

Besides the mud liquid plant, GN Solids Control can also provide waste management systems for both drilling cuttings treatment and drilling fluids treatment, including chemical dosing and decanter centrifuge. For mud liquid plant, clients can invest in such a system to treat the used drilling mud, to remove the particles from the drilling liquid and return the clean mud back to the mud plant.
