The choice of dimension for Mud Tanks

Mud tanks are the base of a drilling mud system, regardless of oil and gas drilling mud solids control systems, or HDD or CBM or TBM, or whatever.  When there's drilling and there mud can be used, it's important to possess mud tanks.

It's not a difficult job for an engineer to create a mud tank using the modern soft-wares like AutoCAD or three dimensional drawing tools, but exactly how to assist the client to obtain an ideal tank in the beginning time? May be the asked for storage capacity of tank enough for design? GN Solids Control shares some suggestions.

1. When the first is requesting a solids control system for oil and gas drilling, this means the drilling mud comes from the well hole directly. Within this situation, we have to consider the weir height of shale shaker when selecting the peak of mud tanks. If the entire height of shaker weir and tank height is simply too large, it's possible that the mud can't fall in the pipelines from well mouth. This tip is particularly for workover rigs. For meeting customers’ different demands, GN has designed its shale shakers to supply several optional weir types.

2. Throughout transportation, what equipment within this system might be taken apart, while which equipment has to be fixed on tank and moved together? Actually, mud agitators will always be on mud tank, while shale shakers and mud cleansers will always be removed temporary.

3. Can there be any legal requirement in the users’ local for that biggest width or biggest height? This should be taken care.

4. just in case of worldwide business, the machine have to be shipped by ocean. What type of ocean shipment will the consumer accept?


Obviously, the storage capacity can be the fundamental requirement which needs to be meeting in the beginning stage. GN always believes to supply the clients with best and appropriate solution.

Motor Control Centre For Drilling Site

The thermal desorption system is controlled through an Allen-Bradley Programmable Logic Controller model PLC5/20 mounted inside the free standing control container. The process can be monitored and controlled through the use of PC/AT Operator Interface Platform on a desk top computer and viewed on a full 19” monitor.  Process conditions are continuously monitored by an array of instrumentation installed on the process equipment. The state of the instrumentation represents real-time conditions of the process and allows for process information to be reported by the PLC to the display screen. The micro process or, as an integral part of the PLC, monitors the information received from the input field devices, performs the routines programmed in the ladder logic code, and delivers commands to the output instruments to automatically control system operations.  The operator inputs required process criteria directly to the terminal to specify the conditions of the system operation. The PC based software relays this criteria to the
PLC, which performs the logic functions to meet the specific process requirements.

Equipment status, process criteria and alarm conditions are displayed on graphic display screens within the operator’s interface terminal, allowing the operator to perform process and machine diagnostics. The graphic display alarm and process screens also provide operators and maintenance personnel with information that aids in trouble shooting the alarm condition. The control system is user friendly and employs asimplistic method of interfacing the operator with the equipment. DC5424

When you received inquire from clients, you need check if they have motor control centre , cause this will affect price and design for electrical control system for all motors on solids control system a lot. If they don’t have motor control centre, you will need include all control component for all your motors but if they do have a motor control centre, you need supply control componenet for motors larger than 30KW to save cost for your clients.
