Drilling waste recycling System Working

The process of drilling oil and gas wells generates large volumes of drill cuttings and used muds. Onshore and offshore operators have employed a variety of methods for managing these drilling wastes. In offshore, options are limited to cuttings reinjection, offshore discharge and transportation to onshore disposal facility. This is as a result of the limited space and stringent environmental regulations governing an offshore drilling operation. As a result some offshore wastes have to be transported to an onshore facility for treatment and disposal. Onshore operations however, have a wider waste management options. The selection of a disposal method for a particular location depends on other factors which must be evaluated extensively before implementation. The main aim should be towards ensuring an environmentally safe waste disposal approaches.

The solids control system forms the first waste management practice in any drilling operation. It removes drill cuttings from the drilling mud at the surface just before the mud re-enters the mud-pit for recirculation. Apart from drill cuttings, the solids control equipment also removes some gases and other contaminants in the mud before they are re-circulated. The early removal of these solids avoids accumulation and clogging of the system and the separation devices sizes of solids. The components of the solids control system will depend upon the types of drilling fluid used, these formations being drilled, the available equipment on the rig, and the specific requirements of the disposal option. But basically, standard solid control equipment will comprise of shale shakers, degassers, desanders and desilters. The mud passes over a shale shaker, which is basically a vibrating screen. This removes the larger particles, while allowing the residue to pass into settling tanks. The finer particles are further removed in the desanders and desilters. If the mud contains gas from the formation it will be passed through a degasser which separates the gas from liquid mud.

Cutting reinjection is common to both offshore and onshore operations. However, due to the availability of space for an onshore operation, there are a lot more management options available. The most common onshore disposal method is perhaps onsite burial. Other methods include the construction of a waste reserve pit, thermal methods like incineration, kilns, open burning etc. There are also biological methods like composting, land-spreading, land-farming etc. In an onshore environment, waste can be treated and used for other beneficial applications like road spreading, construction materials etc. This section explores the various options available for onshore waste treatment and disposal.

Tips For Solids Control Of Drilling

Tips For Solids Control Of Drilling: The rule of solids control is always the same: Success to any method of solids control is achieved when cuttings are kept intact from bit to surface.

The purpose of using mud gas separator

The main purpose of a mud gas separator is to vent the gas and save the drilling fluid. This is important not only economic reasons, but also to minimise the risk of circulating out a gas kick without having to shut down to mix additional mud volume.

In some situations the amount of mud lost can be critical when surface volume is marginal and on-site mud supplies are limited. When a gas kick is properly shut in and circulated out, the mud gas separator should be capable of saving most of the mud.


The atmospheric type separator operates on the gravity or hydrostatic pressure principle.

The essential design features are:

• Height and diameter of separator
• Internal baffle arrangement to assist in additional gas break-out
• Diameter and length of gas outlet
• A target plate to minimise erosion where inlet mud gas mixture contacts the internal wall of the separator, which provides a method of inspecting plate wear
• A U-tube arrangement properly sized to maintain fluid head in the separator.

Introduction of Aipu mud tank valve

mud tank valve or mud pit dump valve is used in suction manifold of mudtank to control the inflow and outflow of mud. Features: Verne seal Size: 6"、8"、10"、12"、14"、16" or as per customer's requirement. Operation:
Rotating the valve handwheel to make valve rod move up and down by which the valve plate is lifted up,separating the valve plate and clutch of sealing socket，opening the valve body.

Mud tank valve are made up of following parts:

Outer Pipe

Connecting rod

Mobile Oil Sludge Treatment System

Mobil Oil Sludge Treatment System 

Technology Introduction:

Self-feeding function: With the design of self-feeding equipment,it will transport oil-sludge liquids and solids to the first mobile processing tank,satisfying excessive oil-sludge feeding.

There have the filter screen design at the entrance of self-feeding equipment,

this will avoid other big materials entering into the system.

Pretreatment:

oil sludge will be separated into smaller solids under the work of rotating blades and 

sieve plate.Those are bigger than 20 mm solids are transported to one side of 

collective tank by rotating blades,smaller than 20 mm solids will be pumped to

oil pretreatment tank under the work of sieve plate.

liquefied and Separation

 oil-sludge can be liquefied,purified under the work of chemistry,ultrasound,air flotation,agitation.Thus the crude oil would be separated out.

Fine separation

Sperating the oil-sludge with three-phase high speed frequency centrifuge.

Water and oil separation

Water will be pumped into water tank and oil to oil tank through high speed centrifuge from which the hot water can be returned to use.

Replacing your shale shaker screen when you find following phenomenon happened

Replacing your shale shaker screen 

when you find following phenomenon happened

Shale shaker screen is wearing parts in drilling solids separation process,since long time working will make it getting weary little by little.

Shale shaker screen can keep working 7 days,or even 15 days,while in some cases it can only lasted 3 days because it depends on mud property,and whether user have a proper usage or not.

Too much build up of the unwanted solids on the screen panel will cause loss of drilling fluid,and low working separation efficiency of shale shaker.

In above video,there are too much unwanted drilling solids build up on the screening layer,under such circumstance,user should replace it with new screens,or washing the screen when shale shaker stop running.

Aipu Solids Control manufacture shale shaker screen for many years,we provide replacement screen for Derrick,NOV Brandt,Sweco,etc. Customer provide us the screen size,screening layer type,frame material ,then we can make it for you accordingly.
