Drilling waste management process summarize

For drilling waste management, there are many equipment configured in a complete system. Including shale shaker, cuttings dryer, the centrifuge, and so on. We ever talked about the four R in drilling waste management. What is the detail and how to realize expected result.

The Four R’s are one of many ways to describe the waste management hierarchy approach and are important when considering what our drilling waste management product line consist of. The four R’s are:
• Recycle
• Recover
• Reduce
• Reuse

Recycling during waste management

Recycle – Process the drilling fluid for reuse, the drill cuttings may require further processing. The low temperature thermal treatment of NADF cuttings offers the opportunity to recycle the recovered base oil to build new drilling fluids.Similarly, slop water generated during the use of NADF can be treated with chemicals to recover and ultimately recycle much of the NADF portion.

Recovery prior to reuse

Recover – To recover the fluid or reusable materials property. High temperature thermal treatment of drill cuttings will generate a recovered hydrocarbon which is not suitable for reuse in drilling fluids due to “cracking” of the oil caused by the higher treatment temperature. However, this hydrocarbon is often suitable for recovery as a fuel oil.
The Drilling Waste Management product line is designed to help maximize compliance with the waste management hierarchy principles, as well as ensuring that local regulations and standards are complied with. Ultimately, disposal will be required in all cases, be it solids and / or liquids.

Reduce waste and cost

Reduce – If we do not generate the waste in the first place, then a reduction is obvious. However, all wells are drilled with the generation of waste. It is possible though to reduce the volumes through a number of means including better planning, a reduction in hole sizes, minimizing washout through the selection of appropriate drilling fluids etc. Such process will also reduce the whole cost and waste disposal

Reused product detail

Reuse – Reuse the valuable products processed by cutting dryer. Furthermore, solids control equipment is key to the reuse strategy. Solids control efficiencies will dictate how much drilling fluid is recovered in a suitable state for reuse in further drillings activities. Poor solids control efficiencies will lead to more solids entering the active system, further reducing their particle size, and ultimately resulting in the requirement to dump fluids as waste, or to dilute, thereby increasing volumes and costs, all of which have a negative environmental impact.

Liquid waste such as waste water and spilt drilling fluids can also be reused in many cases provided they are collected, treated if necessary, and checked prior to reuse.
