How to choose the suitable drilling waste management system

As more and more countries start to control the drilling waste and improve the standard of waste discharge in oil and gas drilling field, drilling waste management becomes more and more popular and important. Many companies have to or want to start their business for drilling waste management. But many clients do not have experience on it. They do not know how to choose the suitable equipment or systems for their activities.

As a worldwide famous brand on mud solids control and drilling waste management, GN Solids Control start its research and development department for drilling waste management and industry waste management for many years. Below is a brief introduction of normal drilling waste management equipment to help the users make decision.

1) High G drying shaker.

It is also named High G dryer, cuttings dryer. It utilizes high G force up to 8.0G to dry the cuttings. If there are big particles in the solids waste, high G shaker is requested. It can remove big size solids and even metal particles. The high G shaker can remove solids above 100 microns.

It is mainly used to treat the water base mud and water based mud cuttings. It can also be used for oil based mud treatment in some cases.

When the high G drying shale shaker is used to treat oil based mud and cuttings, it can only reduce the oil on cuttings (OOC) to 10 ~ 15%.

2) Vertical cuttings dryer

It is also called vertical centrifuge or vortex dryer. It utilizes centrifugal force up to 420G to separate the fine solids and recovery the usable drilling fluids. The screen opening of VG dryer is 0.5mm, 0.35mm and 0.25mm. It cannot allow big size sizes solids or metal particles; otherwise, it will be broken.

Vertical cuttings dryer is mainly used for oil base mud and cuttings. It can reduce the oil on cuttings to 3 ~ 5%. In this case, the solids discharge is on a very dry condition and it is easy for shipment. And the solids with 3~5% OOC can be discharged directly in many countries. If not, it is also easy for next treatment.

3) High speed centrifuge and big bowl decanter centrifuge

It utilizes the high centrifugal force to separate the very fine solids to 2～5 microns. It is used after high G shaker and vertical cuttings dryer, for further separation.

There are many other equipment used for drilling waste management, we will introduce in next file.

GN Containerized Waste Management Package intended for Russia

Leave a reply

As China primary manufacturer for solids control and drilling waste management programs and equipments, GN Solids Control has been one of the most popular brands in Russia for countless years.

The main spare parts regarding vertical cuttings dryer tend to be as below, most of the servicing cost is from these kind of spare parts:
(1) Screen basket, the particular screen basket and screen frame are separated ingredients and they are balanced separately. Typically the screen basket scraper is usually installed to prevent the dismissed fluids from blocked around the screens, sometimes the solids content is very high, it can be difficult to get down from the window screens. Based on different drilling cuttings conditions, the replacement period of time will be different for the screens, could you check with GN sales electrical engineer team for the required volume in one year.

(2) Flites and also Cone Rotor Assembly, the actual 8 flites are permanent on the rotor assembly, it is advisable to replace it completely. The travel arrangements are used to prevent cuttings hindering the screens and scraping the mud inside the monitors.
(3) Bearings replace time depending on actual working time.
(4) Bell jar with scraper, the particular scrapers are used for solids relieve scraping.
(5) Liquid discharge wedding ring, it is not easy to be damaged commonly, 1 set is required since back up.
With flushing pump and air knife to offer pressurized cleaning, that is why GN cuttings dryer can be used with regard to both WBM and OBM.

Centrifuge for Solids Control and Waste Management

Leave a reply

In oil and gas industry for solids control equipment, the centrifuges are more and more used for separating out the fine and extra fine particles from the drilling mud system. In fact, they are taking over the former position of hydrocyclones like the desander cones and desiter cones.

Depending on the applications, the centrifuges could be divided as following items. And GN Solids Control, as the leading centrifuge manufacturer in China oil and gas industry, GN has a complete series of centrifuges, and such centrifuges cover all applications needed in the solids control and waste management systems as below:

1. solids control centrifuge. This is the centrifuge used in solids control system, as the fourth step for separate out the solids from the drilling mud. Normally, there are 2 centrifuges used in a solids control system for a large horse power system, one is for separating the valuable drilling material barite, which is expensive in price and could be re-used in future projects, the other is for separating out the particles which are too fine for the desilter cones. In most cases, GN clients use GNLW452 for barite recovery and GNLW363-VFD for extra fine particles in solids control system.

2. waste management centrifuges, for further treatment of the drilling liquid, the dewatering centrifuge. When the drilling fluid is used and reused for several times, there are extra fine particles in the drilling fluid are too fine for the centrifuge itself to get them out. So the end users need to add chemicals to merge them to be bigger, big enough for the centrifuges. In this case, GNLW363CG-VFD is recommended as the dewatering unit. And also, GN has dewatering unit available.

3. waste management centrifuge for further treatment of the solids discharged from the solids control system. When the solids are collected from the solids control system, they are not dry enough and couldn’t be discharged directly. So for the water based mud, there’s a drying shaker of High-G force and for the oil based mud, there’s a vertical cuttings dryer before the decanter centrifuge. GNLW363CG-VFD of high speed decanter centrifuge is ideal for this application. And GN also has GNZS594HGE-LD drying shaker and GNCD930CD Vertical cuttings dryer for the complete system.

Drilling cuttings solidification unit and cuttings disposal solution

Leave a reply

Drilling cuttings solidification unit is one of the solution of cuttings disposal, it is also called stabilization unit. It is an effective solution for both water based cuttings disposal and oil based/ synthetic based cuttings disposal.

Why should we pay more attention of cuttings disposal？

Obviously, The waste cuttings will damage the environment, lead a heavy pollution and contaminate the under groundwater and influence the Sustainable Development.

There are 4 common ways for the drilling cuttings disposal”

(1) Thermal Desorption Unit, Mechanical separation of drilling cuttings waste treatment with dewatering unit, which is the most popular solution right now

(2) Cuttings re-injection (CRI)

(3) Bio-remediation

(4) Solidification unit/ stabilization unit

Modular Drilling Waste Management

GN solids control is specialist for the mechanical separation of drilling cuttings. GNCM-40A & GNCM-40B is our standard drilling waste management system for oil based drilling cuttings, especially for international client, it is design suitable for container shipment. The main difference between them is the installation of the decanter centrifuge, the centrifuge is installed on the telescopic skid in proposal A, the centrifuge is installed on the catch tank on proposal B, they are 2 main methods in the existing projects.

The modular drilling waste management unit including high-G drying shaker unit and decanter centrifuge telescopic skid unit are the main equipments for water based cuttings treatment.

After treated by GN drilling waste management unit, solidification unit will be used for water based mud, and thermal desorption unit will be used for OBM and SOBM. The OOC in the discharged dry cuttings from the vertical cuttings dryer is under 5%, sometimes it reach 3.7%, in some countries, it is acceptable for environmental standard for land filling. In some counties where has more strict environment standard for the cuttings disposal, a further equipments TDU is necessary.

GN Solids Control, as TOP solids control manufacturer in China, has been the equipment supplier of the oil service companies for many years.Usually, in order to provide a better after sales service, GN Solids Control sends a checklist for customer to fulfill.
