What is Solids Control?


Management of waste through solids control is a process that entails the use of solid particles from rocks. Oil drilling has become a significant threat to the environment. In the drilling process, the rock cuttings are separated from the mud. The rising demand to reduce the negative impacts associated with oil drilling has led to the need for solid controls. Convenient removal of solids from mud in the drilling process dramatically reduces the volume of waste from oil drilling operations. An improvement in the drilled solids through good deep drilling lowers the waste of several oil barrels. Separating solids from the drilling mud makes it more suitable for recirculation into the system. Some of the equipment used in solids control are such as:

  • Mud tanks used in storage and mixing of drilling mud
  • Shale sharer to get rid of big sized solids
  • Desander for the removal of mid-sized solids
  • Desilter that is used to remove solids of small sizes
  • Mud cleaner
  • Centrifugal pump to offer pressure and volume necessary in the operation of the hydro clone
  • Vacuum degasser for the removal of air from the mud
  • Conveyance system for the transportation of cuttings
  • Cutting dryer to remove moisture from the rock settings under the mark of 5%
  • Transportation system
  • Dewatering unit to remove fine solids
  • Decanter centrifuge for the recovery of barite for compliance with environmental standards
  • Mud cooler for under applications using high temperatures 

Solids Control Techniques

Solids control plan should move towards a sustainable management plan and make better use of resources. Recycling depends on effective sorting. There are various sorting techniques, some that are bound to rules and regulations concerning the environment. The disposal of waste entails dealing with sorting of waste materials, which comprises the following methods:

Drum screens or trammel screens

The machines separate items based on the particular size. Raw waste material is put in a giant rotating drum perforated with holes of a specific size. Objects with smear diameters compared to the holes may fall through while large particles settle in the drum. Changing the size of the drum will separate the waste further.

Induction sorting

Waste materials are transferred by a conveyor belt comprising of a series of sensors underneath. The sensors find different types of metals, which then separate through a system of quick air jets linked to the sensors.

Separation through Eddy current 

The method is used for separating different metal types. An ‘eddy current’ takes place when the conductor is exposed to a magnetic field that keeps adjusting. It is a magnetic method of separation of ferrous and non-ferrous waste.

Use of infrared sensors

Illuminating items reflect light in the spectrum infrared wavelength. The infrared sensor that closely differentiates between materials through reflection of light via the items.

X-ray technology

X-rays can be utilized to differentiate between varying types of band waste depending on the density.

Manual sorting

Manual sorting of solid waste is still a common technique used even in the modern world.

It is impossible to undertake an oil drilling task without generating waste. There are varying laws governing site solids control. Site waste management plans save various sectors from significant sums of money in a way that is also sustainable. This results in reduced consumption of energy and low rates of raw material consumption.
