 Introduction
Solids control equipment is essential on rigs to eliminate
unwanted solids from the drilling fluid system. The primary
equipment, arranged in the order of flow from the bell nipple,
includes shale shakers, hydrocyclones, and centrifuges.
Additional components, such as flocculation systems, can be
integrated to enhance solids removal efficiency (SRE), ensuring
superior drilling fluid quality and performance.
Effective solids-control techniques play a critical role in reducing
drilling fluid maintenance costs, minimizing cleanup and disposal
expenses, and lowering the overall cost of drilling operations.
These principles were first acknowledged in the oil industry
during the late 1800s, when open earthen pits were utilized to
separate cuttings from the borehole.
The process utilized a series of weirs and settling pits, where solids were naturally separated through
gravity. The cleaned mud would then flow into a suction pit, ready to be recirculated down the hole.
This innovative approach marked the beginning of solids-control techniques in drilling operations

 Reactivity of Solids
·
Inert Solids
■
Inert solids only have an effect because of their physical presence e.g. Sandstone,
limestone, and barite
■
Controlled by keeping LGS concentration within pre-set limits
■
Maximum LGS for water-based fluids is usually < 6 % v/v
·
Active Solids
■
Have an effect because of their physical presence and reactivity e.g. Bentonite and
some polymers
■
Mainly react in water-based muds
■
Concentration is normally expressed as CEC or MBT(C)
■
Controlled by keeping the MBT content below 30 lb/bbl for water based mud
(preferably below 20 lb/bbl)
■
Active solids show little effect in oil-based muds
 Impact on Fluid Properties
FLUID DENSITY Influence of Solids on Drilling Rate

Drilled solids increase the fluid density
resulting in REDUCED ROP due to:
■
Increased hydrostatic head 80

Drilling Rate (ft/day)

■
Cushioning effect of solids between the
bit and formation 40

■
The increased hydrostatic head may
also result in differential sticking

Solids Content (% v/v)

Impact on Fluid Properties
FLUID VISCOSITY
●
Increased pressure loss and gels in drill pipe and annulus
■
Less hydraulic power (poorer ROP and hole cleaning)
■
Higher ECD (fracture formation)
■
Higher swab and surge pressures (fracture or swab formation)
●
Reduced equipment efficiency
■
Solids control (high surface losses, high mud solids)
■
De-gasser (gas-cut mud, reduced pump capacity & increased wear)
■
Rig pumps (pump not priming due to cavitation in suction)
●
Poor fluid displacement
■
Cementing (poor cement bond)
■
Drilling fluids (contamination)
●
More difficult to add chemicals (especially colloidal materials)
Impact on Fluid Properties
FLUID LOSS CONTROL
●
A small amount of drilled solids may help reduce fluid loss as new mud
may not have an adequate particle size distribution
●
Excessive solids results in thick filter cakes with reduced fluid loss
control, resulting in:
■
Increased torque and drag
■
Drill string or logging tools hanging up
■
Differential sticking
■
Poor cement to formation bond
■
Formation damage due to fluid invasion (emulsion blocking, interstitial clay
swelling, etc.)
■
Log interpretation difficulties
■
Higher swab and surge pressures
Impact on Fluid Properties
INHIBITION
●
Reactive solids will reduce the level of inhibition
●
Increase in surface area will reduce available inhibitors
■
Shale inhibiting polymers, polyols and cations
■
Corrosion inhibitors

LUBRICITY & STICKANCE

●
Excessive solids will increase Stickance Factor
●
Increase in surface area will reduce available lubricants
Solids Removal Techniques
●
Eliminate contaminants at first possible If you can remove this
opportunity
■
Minimum physical handling
■
Minimum volume of liquid discharged to the
environment
●
Prevent solids degradation
■
The centrifugal pumps
■
The mud pumps
■
The drill string and nozzles
■
The bit
■
The hole You can stop this happening
Screen Deck Configuration
●
Screens can be fitted onto the shaker in different arrangements depending on
the type of shaker
●
The coarser screen should be fitted on the upper deck and the finer screen(s)
on the lower deck
●
If a too fine a mesh is on the top screen the screened fluid may land on the
second too close to the solids discharge side giving very wet cuttings
●
Flowback pans will reduce this but may change the shaker motion
●
If screens of different sizes must be used on the same level, the finer screen
should be at the header box - the finer solids will 'piggy-back' off the shaker
Screen Classification
●
Historically screens were referred to by the number of openings per
inch, regardless of opening size
■
E.g. S80 screen is 80 x 80 mesh, with 80 openings in the X and Y axes
■
B60 screen could be 60 x 40, 60 x 20 or even 40 x 20 rectangular mesh depending
on manufacturer

●
API have introduced new classification: A x B ( C x D, E)
A = number of openings per inch in the flow direction
B = number of openings per inch perpendicular to flow
C = Opening size in the flow direction (microns)
D = Opening size perpendicular to flow (microns)
E = Percent of open area of the screen
For Example: 60 x 60 (234 x 234, 30.5)
●
This system cannot be applied to complex weaves
Screen Motion
Three types of motion
●
Conveys solids to the solids discharge
end
Linear
●
Allows liquid to pass through the
screen
●
Creates a limited amount of G-forces Elliptical
●
For solids conveyance
■
Linear motion is considered best Circular
■
Elliptical is second best
■
Circular motion is considered worst
Screen Capacity
Capacity depends on: Screen Plugging
●
Screen size, surface area and condition
●
Amount, size and type of solids in fluid
●
Solid layer permeability
●
Fluid type and properties (density,
viscosity, surface activity)
●
Screen angle, motion and vibration
amplitude

 Operational Remarks
NEVER by-pass the shale shakers If screens plug try finer screens first
ALWAYS use the finest mesh possible Keep a complete range of screens - spares should
be at hand to make quick screen changes

Regulate the flow over the shakers The best screen repairs are made with Devcon -
silicon sealant can also be used but does not last

Monitor the shakers and screens continuously If > 10% of the screen has been repaired, use a new
screen

Choose screens and adjust angle to keep fluid covering Ensure maintenance program is followed
2/3 of the screen

Keep record of screens in use and hours run Keep a record of which screens are in use close to
the shakers for all to see

Switch shakers off during trips to prolong screen life Keep old screens well stacked and labelled
Use only one shaker when RIH When using OBM clean screens with high pressure
base oil - not water
 Advantages and Disadvantages
Simple to operate Flow rate dependent on mud properties
Reliable Constant shaker watch required
Cut point is independent of mud properties Expensive, relatively high running costs, large
footprint
If screen aperture is known the cut point is defined Screens may develop tears (especially fine screens)
Able to process relatively large volumes Bottom screen of double deck shaker difficult to
inspect
Easy to inspect (except for bottom screen on double deck Screens may plug with near-sized particles (sand,
shaker) LCM, ...)

Solids can be removed before mechanical degradation Screens may blind (active clays, polymers, water-
occurs wet solids in OBM)
Mechanical failure or rig movement may cause
excessive mud loss
Adjustments to drilling parameters or screen size
are required when mud temperature, weight,
viscosity, or solids loading changes
Installation
●
Cascade System - The fluid goes over a conventional circular motion shaker
(scalping shaker) to remove the larger particles prior to going over a linear motion
shaker.
●
Mud-Cleaner - The shaker can also be used as a mud cleaner when desilting cones
are mounted above the shaker.
●
Access - The shakers should be installed such that the screens can be changed easily,
both the actual replacement and the tensioning of the screens.
●
Ventilation - Required (either natural or forced ventilation) in the shaker-house to
prevent the accumulation of vapors. Ventilation is especially important with OBM.
Sand Trap
The sand trap in a drilling rig is a device used in the solids control system to remove sand and other
heavy particulates from drilling fluid before it is recirculated back into the well. It helps protect
downstream equipment like mud pumps, shale shakers, and desanders from excessive wear and damage
caused by abrasive particles.
●
The sand trap is a gravity settling pit
●
Due to short residence time and small particle size in underflow - not very effective during normal
drilling conditions
●
If the shale shaker screens never ripped then the major justification for a sand trap would disappear
●
Fluid should exit trap at opposite side via an overflow gate
●
Sand trap should have a sloping bottom and dump valve to discharge solids without discharging
excess fluid
●
It should not be dumped during mud circulation
●
It should be by-passed when weighted muds or OBM are used
●
Dump valve should be locked shut if OBM is used
Degasser
The degasser is a critical piece of solids control equipment used to remove entrained gases, such as
methane (CH₄), hydrogen sulfide (H₂S), and carbon dioxide (CO₂), from the drilling mud. Removing
these gases is essential for maintaining mud density, preventing blowouts, and ensuring safety on the
rig.
●
The shale shaker and circulating system are not very effective at removing gas from the mud,
especially at higher mud weights
●
Centrifugal pumps, hydrocyclones and the rig pumps loose efficiency if the mud is gas cut
●
The degasser should be installed between the sand trap and the first hydrocyclones
●
When the degasser is not in use its suction pit should be kept empty to prevent blocking of the
suction line due to solids settled from the mud
Equalization
●
Each piece of equipment, except the centrifuge, is (normally) able to process a
volume larger than the circulating rate
●
Equalising gates between the pits prevent any one pit from sucking dry
●
The equalizers are positioned in the separating pit walls at either a high or a low
position (over and under flow)
●
An overflow from one tank to the other ensures:
■
Sufficient suction for pumps
■
Constant volume level (required for kick detection)
●
An underflow from one tank to the other ensures:
■
Prevention of solids accumulation on the bottom of the pit
Separation Efficiency
The separation efficiency of hydrocyclones depends on four general
factors:
●
Hydrocyclone design
●
Flow parameters
●
Fluid properties
●
Particle properties
Hydrocyclone Design
The main design variables that control the hydro cyclone
performance are:
●
Cone diameter
●
Cone angle
●
Cylinder length
●
Feed inlet diameter
●
Apex (underflow) diameter
●
Vortex finder
●
Cone material
Flow Parameters
●
Underflow opening on most hydrocyclones can be adjusted to obtain optimum feed
head
■
Apex diameter is increased to correct for excessive feed head
(lowers balance point reducing centrifugal force and in turn lift force)
■
Apex diameter is decreased to raise the balance point to correct for low feed head
●
Excessive feed head will give rise to
■
Reverse flow above the apex causing dryer cuttings liable plug the unit
■
Increased bowl wear
●
Low feed head will cause balance point to fall outside cone
■
Excessive liquid exiting the apex, characterised by rope discharge
■
This is an inefficient condition for hydrocyclones in normal use
Particle Properties
●
Particle characteristics are important in separation efficiency
■
Particle size and shape
■
Particle density
■
Solids concentration
●
Effect of particle density and size on settling velocity is clearly shown by
Stoke's law
●
Particle shape also influences its settling behaviour
■
Oblong shaped particles, because of their high drag coefficients, will be retarded
more than spherical shapes
●
Fine particles will carry more liquid than an equal volume of coarse
particles
 Particle Properties
●
Volumetric concentration of solids can pose settling problems
■
Viscosity increase
■
Particle-to-particle interference
■
Overloading
●
Overloading occurs when
■
Solids concentration in feed is too high
■
Solids are coarse enough to settle
■
As a result more particles are delivered to apex than can be discharged
●
Overloading is characterised by
■
Rope discharge
■
Increase in median cut point

Advantages and Disadvantages
●
Advantages
■
Simple to operate
■
Inexpensive to purchase and maintain
■
Used for cost-effective dumping of mud
●
Disadvantages
■
Performance affected by mud properties
■
Cut points not as low as advertised
■
Larger sizes (6” and 12”) becoming redundant
■
Centrifugal feed pump causes solids degradation
■
High wear rate
■
Bulky and requires a correctly sized pump
■
Wet solids discharge (not suitable for OBM or expensive fluids)
■
May plug or cause excessive mud loss
■
Difficult to adjust
Installation
●
Number of cones should be sufficient to handle the maximum flow
●
Two banks of hydrocyclones (each with its own feed pump) allows one to be shut
down when circulation rate is decreased
●
Strong siphon can be created if overflow header extends several feet below cone
apex
■
Increases air intake and may prevent solids discharging
■
Can be eliminated by siphon breaker in overflow line
●
Performance figures question hydrocyclone effectiveness
■
Three or more linear motion shakers will make desanders redundant
■
Underflow often too wet to be economically or ecologically justified
●
Frequent application with 'dump-and-dilute' water based muds
■
Desander underflow ~3% of the feed rate (2% for a desilter)
■
Three 12" cones may discard as much as 65 bbl/hr
Operational Remarks
●
Check the cones frequently and unblock any that are plugged
●
Carry out spot checks to evaluate their effectiveness (solids removal and
separation efficiencies)
●
Before spudding balance the cones (using water) by adjusting the apex until
the underflow amounts to a slow drip
●
If this is not possible adjust the apex during mud circulation until a spray
discharge is obtained
●
Check the manifold pressure frequently
●
Remember the hydrocyclone may do more harm than good as the feed
pump impeller will cause particle degradation
Mud Cleaner
●
Designed to screen hydrocyclone underflow
■
Reclaim base liquid
■
Reclaim discarded barite
■
Produce relatively dry cuttings
●
Screen sizes vary between 100 and 200 mesh (325 mesh are claimed
but rarely used due to plugging and screen wear)
●
The overflow of the cones and underflow of the screen is returned to
the active system
●
The adjustable parameters are:
■
Number of cones
■
Size and type of cone
■
Size of screen
■
Vibrating speed
Operational Remarks
●
Two banks of hydrocyclones (each with its own feed pump) are
preferred
■
Allows one to be shut down when circulation rate is decreased
■
Less slurry is processed and finer screens can be run
■
Produces drier solids with a finer cut (although the total mud-cleaner capacity will
be reduced)
●
The mud cleaner operation is basically a combination of a set of
hydrocyclones and shakers
●
All the operational points for the shaker and hydrocyclone also apply to
the mud cleaner
●
Mud cleaner shakers are inferior to flowline shale shakers
Application
●
Main application is with unweighted muds where the base fluid is expensive or
cannot be dumped
●
For weighted muds the cost in lost barite is considerable
(discharge should be tested to determine if it is cost effective to run)
●
The mud cleaner does not remove fines and will not have a large impact on the
viscosity
●
Hydrocyclones may be placed above the shale shakers to achieve the same result as
a mud cleaner
■
Improves capacity and provides drier solids
■
Should only be done if there is sufficient shaker capacity (say 5 shakers)
Advantages and Disadvantages
●
Advantages
■
Reclaims expensive fluid and some barite
■
Produces relatively dry cuttings
■
Easy to operate
■
Compact
●
Disadvantages
■
Recycles fines through screen
■
Discards barite with the cuttings
■
Discharge wetter than centrifuge discharge (problems dumping OBM cuttings)
■
Limited capacity
■
Degrades solids (due to feed pump impeller)
■
Separation partly depends on cone performance (normally poor)
■
Requires correctly sized feed pump
Centrifuge
●
Usually, last piece of solids control equipment (processes about 10% of flow)
●
Positive displacement pump feed
■
Constant flow rate
■
Little degradation of solids in the feed pump
●
Separation (settling) enhanced by high G-forces
■
Separation efficiency ~ 95% for 20 mm and 50% for 10 mm particles
■
Ultra-fine particles (~ 3 mm) can be removed
●
Perform multiple tasks
■
Solids removal
■
Barite recovery (removal of colloids)
■
Recovery of base fluid from hydrocyclone underflow
■
Recovery of oil from cuttings for ecological and economical reasons

Feed Rate
●
Feed rate can be readily adjusted - it should remain constant at the
selected capacity
●
To prevent solids degradation centrifugal pumps should not be used
●
Positive displacement pumps driven by a variable speed motor to
adjust the feed rate are most commonly used
●
Feed rate determines the residence time - high feed rate will result in:
■
Shorter residence time
■
Poorer cut point
■
Larger solid recovery in mass per unit time
Bowl and Scroll Speed
●
Bowl speed controls the centrifugal force - it can be altered on many centrifuges
(1,500 - 3,500 RPM)
●
Scroll rotates in same direction as bowl but at lower RPM (on some machines the
scroll rotates faster than the bowl)
●
Scroll speed is controlled by differential speed selector which operates the gear
box - typical gear box has a ratio of 80:1
●
Slower conveyance results in:
■
Increased torque
■
Drier cuttings
■
Greater risk of plugging the centrifuge
●
Faster conveyance results in:
■
Reduced torque
■
Wetter cuttings
■
Bigger pool disturbance resulting in poorer cut points
Advantages and Disadvantages
Advantages
●
Low cut point
●
Removes solids in the driest possible form
Disadvantages
●
Complicated operations, especially start-up and shut-down procedures
●
Fine HGS and coarse LGS may be separated simultaneously resulting in recycling of
LGS during barite recovery or removal of HGS in solids removal
●
Removal of essential mud solids such as viscosifiers and excess lime
●
Limited throughput (this may be an advantage if mud properties are severely
affected by removal of essential solids)
●
High rental and purchase cost
●
High operating costs due to wear
Installation
●
To make best use of the centrifuge, use the following as feed:
■
Returns to the active
■
Mud cleaner underflow
■
Mud from active pit
■
Mud from reserve system
(Last two options required to centrifuge the mud system during trips or other times
when mud not circulating)
●
Divert the solid and liquid effluent to either the dump-chute or active
system. The following is required for the dump-chute:
■
True vertical drop (preferably with flushing system)
■
If not true vertical, at least 45° (must be fitted with a flushing system)
■
Sufficient diameter
■
No 'crooked' lines or sharp bends
Installation
●
When solids are diverted back to active, sufficient energy
should be available to re-suspend the solids into the liquid
■
Installing a strong agitator in the receiving pit
■
Installing a hopper underneath the solids discharge (similar to the
mixing hopper) - this could be fed from the desilter overflow
●
Oil recovery centrifuge installations
■
Normally have less versatility
■
Require special feed pump
■
Units should be skid mounted
■
Normally returned to base when not required

Shale Shakers
Linear Motion Shakers IDEC 448 AG
High G-force in a shaker is essential to convey the amount of
cuttings generated while drilling hole, to dewater drill cuttings to
reclaim expensive drilling fluids, and to minimize waste. While
drilling top-hole sections, where heavy, high-volume cuttings are
typically encountered, shakers need to generate high G-force to
effectively convey dense solids.
As conditions change in drilling and fluids, the G-force of IDEC shakers can be
adjusted using an optional VFD control panel, therefore changing the cuttings
conveyance velocity. This can be done without shutting down the shaker and
adjusting the weight settings on the vibrator motors. As a result, IDEC can
provide drier solids, improved drilling fluid recovery, longer screen life and
reduced operating costs.
