![]() ![]() Most mud systems come with integrated diesel generators to power the units. and for some small mud system with small tank, there will be no need to equip an agitator. and also the volume of each compartment of the tank and the tank total holding capacity should also be considered.Īgitator configuration should be considered according to the depth of the tank to suspend the solids in the mud, but not settle in the bottom of the tank. So it critical to select a specific motor power & the diameter of the inlet & outlet, to achieve a right power & lift.Ī large mud hopper with a properly sized venturi is an essential part of the mud mixing and recycling system. It is normally used to transfer the mud from tank to hydrocyclone, or from one compartment to another. Pump is an important part in a mud system. For large flow rate & high solids loading, it is advisable to use big diameter cones, such as 10" or 12", and quantity is determined by the mud flow rate. Hydrocyclones with different cone diameters have different throughput capacities and cut points. The screen deck angle should also be adjustable while drilling to achieve a proper residence time. G-force should be adjustable by a variable speed device. ![]() The screen is much critical for the quality of shale shaker, and screen selection is a key factor to achieving dry solids discharge. and it is identified by three critical factors: Shale shaker is considered as the first & an important solids control equipment in the mud system. It become very critical on the volume of return mud, the solids loading, and the quality of the return mud. There are a few consideration that should be taken into account at a minimum when selecting a new mud system: The drilling fluid can not bypass shale shakers & hydrocyclones which can be decander or desilter, or integrated mud cleaner. Both Shale shaker & hydrocyclone determine the capacity of a mud system, but basically, formation condition, project environment, and mud system configuration commonly determine the processing capacity of a mud system. ![]() Generally speaking, a mud system should be 120%~150% of the mud pump capacity. For example, you can not introduce a 800GPM system for a project that with 1000GPM mud flow. which means the mud system capacity rate should be almost equal with the mud pump capacity. Contractors can be viewed as environmental friendly.Ī effective mud system are required to combine the recycling & mixing function, and the most important principal for an mud system is "Hydraulic Balance".Reduce the rig downtime, waiting on fresh water & disposal trucks.Minimize water usage and bentonite & additives for new mud making.Minimize the disposal fees, truck cost, and drivers/operators costs. ![]()
