Oil & Gas Pump Applications - Drill Cuttings

The Problems Associated With Current Methods of Processing Drill Cuttings

One of the most expensive and troubling issues with drilling operations is the handling, processing, and circulation of drilling mud along with disposing of the unwanted drill cuttings. The drilling cuttings deposited in the half round tank and are typically removed with an excavator which must manually move the drill cuttings out of the waste bin or roll-off box and into the truck. The excavators are usually rented for this duty and the equipment charges can range from $200-300/day. Add in the cost for the day and night manpower and the real cost for a single excavator can be as much as $1800/day.

Excavator safety issues. An excavator can be a safety concern and removing this unit can increase the safety profile along with reducing cost.

Using the excavator method explained above, the unloading of 50 barrels of drill cuttings from the half round can take as long as one to two hours. This task is mostly performed by the solids control technicians. The prime duty for the solids control technicians is to maintain the solids control equipment in good working order. This involves maintenance for the equipment, screen monitoring and changing, centrifuge adjustments, and retort testing to prepare a daily operational summary of the solids control program.

Operating the excavator takes the technician away from these tasks and can lead to poorly performing equipment. Additionally, the excavator has the potential for abuse as some solids control technicians use the climate-controlled cab as a break area or refuge from the elements. Many times, these guys are found asleep on the job.

One solids control company reported the idle time for the excavator can be more than 8 hours for a 24-hour period with 8 hours of operation and 8 hours of shut down time. Fuel and time lost can cause an economic drag on rig operations. And lastly, there have been several accidents on each rig causing a potential for injury, loss of production, and lost revenue as the excavator must be repaired.

Other Drilling Mud & Drill Cuttings Disposal Methods

Currently, most onshore drilling rigs dispose of drilling mud by mechanically loading the used drilling mud onto trucks via excavator or hire vacuum trucks to come and transport the mud away. Another method of disposal is by mechanically loading the drilling mud into poly-lined ponds until a threshold is met, before being trucked off for permanent disposal. Both these options are expensive and require a lot of manpower. Conventional pumps cannot move the drilling mud due to the high viscosity of up to 1000 cp and specific gravity of up to 1.9. This, along with the occasional large cuttings cause a nightmare for centrifugal pumps. Most pumps cannot even move the material and the ones that can have their impellers and volutes chewed up by the abrasive nature of the drilling mud, greatly shortening the lifespan of the pump which leads to frequent costly pump repairs coupled with unscheduled operational downtime.

Offshore drilling rigs follow a similar process in which the mud is loaded into empty drums and held on the oil platform. When a certain number of filled drums is met, the drums are then loaded onto barges or vessels which take the drilling mud to the shore to unload and dispose of.

Generally, there are different versions or models of mud agitators that are being offered to fulfill various customers’ needs more effectively. However, here are some of the most amazing features of these mud agitators’ range that you must know:

Mud agitator motor

Motor power of these mud agitators is ranging from 5.5 kW to 22 kW. You can easily choose the one which is more suitable for your mud agitator needs.

Mud agitator shaft and impellers

However, the impeller speed of these mud agitators is 60/72RPM. While, on the other hand, the shaft length of the mud agitator will depend on the size of the mud tank completely.

Durable agitator

Excellent capacity, longer service life, and high-quality materials along with sturdy construction are making these mud agitators highly durable and reliable.

A Mud Agitator is equipment that is used for a specific purpose – the mixing and agitation of mud. While doing so, it prevents the settlement of the solid phase particles in the tank, which is crucial for the recycling process. The Mud Agitator is basically a speed reducer that is combined with an explosion-proof motor. The motor is horizontally placed for a convenient installation. These elements of the Mud Agitator are basically what makes everything tick. Also, they are robust and easy to maintain, allowing the Mud Agitator to be used in harsh conditions.

Main features of the Mud Agitator

• Impellers

• Speed reducer

• Explosion-proof motor

• Centering Guide

• Worm Wheel & Worm Gear Reducer drive
