What is Important Equipment in Drilling Waste Management?

Drilling Waste management

Drilling waste management entails all processes and precautions required or recommended to ensure a safe environment. Drilling waste contains spent fluids and drilling cuttings that result from the drilling process. The spent fluids and drilling cuttings that are referred to as drilling waste have no use in the ensuing drilling process therefore must be disposed of.

However drilling waste treatment requires that the set environmental management standards and regulations are adhered to for the maintenance of a safe environment and also in order to avoid legal disputes and penalties.

Drilling waste management  system therefore is concerned with using materials, substances and facilities in the drilling process that minimize  drilling waste while at the same time employ proper disposal of waste in a manner that reduces toxicity.

Cuttings dryer is a core equipment in drilling waste management because it enhances environmental protection. Designated to meet the strict environmental conditions and guidelines imposed on disposal of cuttings and work site, it utilizes high-speed decanter centrifuge which optimizes liquid and solid separation in high volume processing.

The cutting dryer has the following characteristics
•    Rational structure built into the bedplate that adjusts and balances the distribution of vibrating motion.
•    Enhanced protection of spare parts with wear proof measures which include use of stainless steel for mesh screen and spiral scraper to guarantee long service life.
•    The torque sensor which helps regulate the motor in case of overload in operation thus ensuring reliable operation.
•    Viewports on cone header and bedplate making it easy and convenient to inspect and maintain the screen mesh and spiral scraper.
•    The equipment uses centralized lubrication station which facilitates ease of flow of lubricant to machine parts and reduces damage due to poor lubrication.

The cutting dryer is a welcome and indispensable aspect of  waste management, designed with respect to maintaining a safe environment.

Drilling waste management system equipment is consist of vertical cutting dryer , D Series Decanter Centrifuge , Screw Pump ……Industrialists and operators are looking for ways to recover synthetic based and oil based fluids used for drilling to reuse them, safeguarding both economic and environmental objectives.

Cuttings dryer reduces the amount of drilling waste that is produced and that which has to be transported and helps in recovering the reusable fluids. This makes a significant impact on the expenditure spend and helps in saving a lot of money, not to mention the environmental benefits.

Cutting dryer also reduces the amount of drill cuttings and wastes.
A normal dryer intake the wet drilling wastes and delivers the same amount of cuttings minus the drilling fluids. The drilling fluids are collected using centrifugal force and such dryers are normally called centrifugal dryers. Conventional dryers involve a number of steps for recycling drill fluids.

The cuttings have to be collected and transported to special equipment. This requires a large amount of manpower. Also, the transportation of cuttings poses several practical problems, such as the degradation of cuttings before they reach a dryer. This leads to the cuttings breaking down and makes fluid recovery more or less impractical, owing to its poor efficiency. As a result, this can actually increase the amount of drilling waste , making the whole process of fluid recovery a waste of time.

But new methods have now been developed by various industries for fluid recovery. It makes use of high speed air and pressure to recover fluids. The air dries the cuttings and is collected by a particular system to retrieve the drilling fluids.

As the machine can now be operated at less power, they require only minimum maintenance and manpower. The operating cost of such machines is way below the cost of centrifugal dryers and is less susceptible to mechanical failure. They also provide a greater output, resulting in a better efficiency.
