What is a telescopic skid for drilling waste centrifuge?

Telescopic skid is a high skid with adjustable height. In drilling waste field, it is mainly used to mount decanter centrifuge.

GN Solids Control company offer telescopic skid with height changed between 2.0m, 2.2m and 3.3m. It can meet most drilling site condition.

When need to use a telescopic skid, the advantages of it?

In mud recycling system (solids control system), there will be many tanks, decanter centrifuge can be mounted on the tank top. Hydraulic phase will fall into the tank under the centrifuge. Then a pump charge mud centrifuge tank to other tank or processing machines.

In drilling waste management system, the centrifuge can be mounted to a telescopic skid. With the skid, the centrifuge fluids outlet port should be higher than other mud storage tank. In this case, hydraulic phase can flow under garavity into mud storage tank or other device already there. No extra tank to store the mud and no need charging pump for the transfer. It can save cost of tank, and save power. And another side, the space under the telescopic skid can be used to mount other machine or device, like VFD control panel, centrifuge feeding pump, or others.

In oilfield drilling, there is a lot for different sludge including drilling waste, water, oil, and cuttings. This makes it to be a tought job to managing the liquid and solids separation. Especially getting enough drying solids from the mixture of drilling waste from mud sytem and tank cleaning waste.Now from GN lastest oifield application cases we have Vertical Cuttings Dryer for the tough job.

For getting oil on cuttings to below 3%, waste management company normally use the Thermal deporption unit (TDU)

Thermal desorption is an ex-situ treatment technology that utilizes heat to increase the volatility of contaminants such that they can be removed from a solid matrix: typically, soil, sludge, filter cake, or drill cuttings. Desorbers are designed as a separation technology to remove organic compounds from such matrices without thermally destroying them. The volatilized contaminants are then either collected or thermally destroyed in secondary treatment units. A thermal desorption system therefore has two major components; the desorber itself and the off-gas treatment system.

Usage for TDU in Drilling Sludge

Thermal desorption is a thermal soil remediation technique that has been utilized at several hundred environmental remediation projects world wide. As a mature technology, thermal soil remediation performance can be predicted with a high degree of confidence.

Besides ultilizing GN Vertical cuttings dryer, the high speed decanter centrifuge is very important for the LGS separation.

Drilling mud types

There mainly 3 types of drilling mud for drilling rig system: Oil based mud (OBM), water based mud (WBM) and Synthetic based mud. According to different drilling rig and different depth, suitable drilling mud type will be used.

WBM (water based mud) is the most common drilling mud type. Most widely be used worldwide and its relative lower cost and lower pollution.

OBM (Oil based mud) is mainly used for very deep drilling and the difficult depth drilling rigs. OBM cost higher and have a big pollution to environment.

SBM (Synthetic mud) is used as the alternative of OBM. SBM drilling waste is relative easy to be treated. It has a lower pollution. At offshore rigs, the SBM drilling waste can be discharged directly to the sea. But it is not stable under high temperature. It is more difficult to get but the total cost lower then OBM and WBM.

Cuttings dryer machine for OBM and WBM

Cuttings dryer used for Oil based mud (OBM) and Waste based mud (WBM) is different. Normally, high G dryer shaker is used for water based mud (WBM), vertical cuttings dryer is used for oil based mud (OBM) and Synthetic based mud (SBM). But a higher standard vertical cuttings dryer can treat all the 3 types of drilling mud cuttings: OBM, WBM and SBM. It request a high standard of manufacturer. Few company can make it.

Decanter centrifuge is a high efficient equipment used for solids control and drilling waste mangement. Many customer, they are wondering how to choose the suitable decanter centrifuge model for their applications. Some customer thought, the big speed, the higher. It is not correct. Some customer believe Variable Frequency Drive (VFD) high speed centrifuge can cover all the speed and G force, it is the best choice. Actually, it is not correct for all conditions.

Below some Question and Answers between customers and the decanter centrifuge manufacturer. It may help you for some understanding.
Q 1. We prefer GNLW363 VFD high speed decanter centrifuge, the highest international standard. The speed adjust from 0~3200rpm, but in case of no VFD we need it to work only with 1400rpm.

Answer from GN: GNLW363 centrifuge is mainly for high speed. We only recommend If you are mainly running at lower speed, we recommend GLW452. It is a 18inch decanter centrifuge, with bigger capacity, better price. GNLW452 is a middle speed centrifuge, normally 1800rpm, GN can mach VFD panel for 0~1400rpm per customers request.
For heavy mud, 452 centrifuges is the best choice to used with solids control equipment to reduce the weight. It is widely used for barite recovery (high gravity separation).
Q2: How can we get fixed speed control for VFD centrifuge?
Answer from GN: Normal, the only VFD control for VFD centrifuge, if customer need both VFD and fixed speed control, you can choose an extra Hydraulic Coupling & Fixed speed control panel. The Fixed speed control panel can be separatedly, or design together with the VFD panel, whichever you like.
Q3: How do services and change of parts happen during guaranty period and who is responsible for doing it after commissioning?
Answer from GN: GN company will send engineer for first time commissioning and training if request by customer. Customer can also send engineer to GN China base for training. For normal parts changing and some small questions after first time commissioning, GN will offer long-distance instruction. If your engineer cannot solve with long-distance instruction, GN can send engineer to jobsite for support.
Q4: We want a centrifuge mostly running around 3200 and 1400rpm, which decanter centrifuge model suitable?
Answer from GN: GNLW363 fixed speed is suitable. We can offer you 2 sets pulley with belt for 2 fix speed. You only need to change pulley and belt to get another speed.
Q5: Do we need to stop the centrifuge while changing pulley and belt for another fixed speed?
Answer from GN: Yes, indeed. You have to stop the centrifuge decanter and when it is stable, you remove the pulley and belt on the machine and change for another set.

Functions of drilling fluids mud desilter

Drilling fluids mud desilter is the 3nd stage solids control equipment. It is usually used after desander. For mud cleaner used for oil and gas drilling field, 4 inch deciliter cone is the most frequency be used. It can remove solid particle around 30~70 microns.

Working principle of drilling fluids mud desilter

Main part of drilling fluids mud desilter is the hydrocyclone cone (desitler cone). It is a kind of pressure device. The separation process is carried out by employing centrifugal forces. Under pressure, drilling fluid with solid particles will flow into the mud desilter cones, after high rotation, bigger and heavier particle will be threw to cone wall, then slide down till drop in apex and separated out. Clean fluids will be moved out from cone top port. So, there will be 2 rotary gas flow in the drilling fluids mud desilter cone, one is liquid contains quantity big solid flow down as cyclone, the other is smaller solid mixed with gas go up as bow wave.

The angle of the fluid entry has been specifically designed to facilitate the flow and separation. The Cones are made of high durameter polyurethane with optional steel inserts, which ensure consistent productivity.
Desilter Cones remove fine sand and silt down to 30 microns.
Desilter Cones are available of 4″ size that have a 2″ inlet and a 2″ outlet.

Available models of drilling fluids mud cleaner

From design, there are mainly 2 types of mud desilter: with under flow shale shaker or without under flow shale shaker. For different capacity, the desilter cone can be used from 4 each to 24 each. Users can choose suitable models per his jobsite detailed condition.
