Derrick Shale Shaker For Drilling Fluid In Petroleum Field
THE INTRODUCTION OF SHALE SHAKER
Shale shakers are components of drilling equipment utilized in many industries, such as coal cleaning, mining, oil and gas drilling. They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called "Mud" due to its similar appearance.
Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as well as convey the drilled cuttings away from the bore hole. These fluids are a mixture of various chemicals in a water or oil based solution and can be very expensive to make. For both environmental reasons and to reduce the cost of drilling operations drilling fluid losses are minimized by stripping them away from the drilled cuttings before the cuttings are disposed of, this is done using a multitude of specialized machines and tanks.
Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.
Shale shakers are considered by most of the drilling industry to be the most important device in the solid control system as the performance of the successive equipment directly relates to the cleanliness of the treated drilling fluid.
THE STRUCTURE OF SHALE SHAKER

Shale shakers consist of the following parts:

1.'''Hopper''' - The Hopper, commonly called the "base" serves as both a platform for the shaker and collection pan for the fluid processed by the shaker screens, also known as "underflow". The hopper can be ordered according to the needs of the drilling fluid, aka "mud" system. It can come in different depths to accommodate larger quantities of drilling fluid as well as have different ports for returning the underflow to the mud system.

2.'''Feeder'''- The Feeder is essentially a collection pan for the drilling fluid before it is processed by the shaker, it can come in many different shapes and sizes to accommodate the needs of the mud system. The most commonly used feeder is known as the weir feeder, the drilling fluid enters the feeder usually through a pipe welded to the outside wall near the bottom of the feeder tank, it fills the feeder to a predetermined point and like water flowing over a dam the mud (drilling fluid) spills over the weir and onto the screening area of the shaker. This method of feeding the shaker is most widely used due to its ability to evenly distribute the mud along the entire width of the shaker allowing for maximum use of the shaker's screening deck area.

:Some feeders can be equipped with a bypass valve at the bottom of the feeder which allows the drilling fluid to bypass the shaker basket and go directly into the hopper and back into the mud system without being processed by the shaker screens.

3.'''Screen Basket'''- Also known as the screen "bed" it is the most important part of the machine, it is responsible for transferring the shaking intensity of the machine, measured in "G's", while keeping the "shaking" motion even throughout the entire basket. It must do all that while holding the screens securely in place, eliminating drilled solids bypass to the hopper and allowing for easy operation and maintenance of the machine. Different brands of shakers have different methods of fulfilling these demands by using specialized screen tensioning apparatus, rubber seals around the screens, basket reinforcement to limit flex, rubber Float Mounts rather than springs, rubber Deck seals and selective vibrator placement.

4.'''Basket Angling Mechanism'''- The shaker basket must be capable of changing its angle to accommodate various flow rates of drilling fluids and to maximize the use of the shaker bed, this is where the angling mechanism plays an important part. The drilling fluid flowing over the shaker bed is designated into two categories:

**''Pool:'' Which is the area of the screening deck that comprises mostly of drilling fluid with drilled cuttings suspended within it.

**''Beach:'' Is the area where the fluid has been mostly removed from the cuttings and they begin to look like a pile of solids.

5.'''Vibrator'''- This is the device which applies the vibratory force and motion type to the shaker bed. A vibrator is a specialized motor built for the purpose of vibrating, While containing an electric motor to provide the rotary motion it utilizes a set of eccentric weights to provide an omnidirectional force. To produce the proper Linear motion a second, counter rotating, vibrator is added in parallel to the first. This is what gives us the linear motion, "high G" shaking of the basket.

THE SCREEN PANELS OF SHALE SHAKER

Screen selection is critical in the operation of a drilling rig as the shakers are the primary stage in the removal of drilled solids. Improper screen selection can lead to, loss of expensive drilling fluids, premature [[pump]] failures, overloading of other solids removal equipment such as a centrifuge, decreased equipment life, reduced rate of penetration and serious problems in the well bore.

A shaker screen consists of the following parts:

1.'''Screen Frame'''- Much like a canvas for painting a screen has to be supported on a frame in order to do its job, this frame differs between manufacturers in both material and shape. Screen frames can be made from materials such as, square steel tubing, flat steel sheets, plastic type composites or they can just be supported on the ends with strips of steel (similar idea to a scroll). These frames consist of a rectangular shaped outer perimeter which is divided into small individual inner panels. These smaller panels differ in shape from manufacturer to manufacturer and have been known to come in shapes such as square, hexagonal, rectangular and even triangular.

2.'''Screen Mesh'''- Just like thread is woven together to create cloth, metal wire can be woven to create a metal cloth. Screen Mesh has evolved over many years of competitive screen manufacturing resulting in very thin yet strong cloth designed to maximize screen life and conductance as well as to provide a consistent cut point. To increase the conductance of a mesh screen you have to minimize the amount of material in the way, this is done by either reducing the wire diameter or weaving the cloth to produce rectangular openings. Rectangular openings increase the screens conductance while minimizing the effect on its cut point where as square openings provide a more consistent cut point but offer a lower conductance.

3. '''Binding Agent'''- The binding agent is the material used to bind the mesh to the screen frame, it is designed to maximize adhesion to both materials while being able to handle high heat, strong vibration, abrasive cuttings and corrosive drilling fluids.

4. '''3D Screen Technology'''- One of the more recent advances in oilfield screen technology has brought us the "3D screen", this technology is an innovative method for increasing the screening area of a shale shaker without the need to build larger machines. When seen from the side these screens look like corrugated cardboard, having a flat bottom and wave like shapes on top. These waves are designed to increase the surface area of the screen panel by building up in stead of out, thereby maximizing the surface area of the screen without the need to build larger shaker screens and in turn larger, heavier and more expensive shakers.

:*The tapered valleys, while moving under high G's, apply a compression force on the solids similar to wringing out a cloth to draw out liquid.

:*Increasing the surface area of the shaker allows the use of finer screens earlier in the drilling process while maintaining acceptable flow rates and penetration rate. Effectively removing harmful drilled solids before they can begin to wear out the solids control equipment.

Although the performance of these screens is quite impressive the only way to truly gauge the performance of any screen is to try it out and collect comparative data of your own.
