Specific Factors

Specific factors that should be considered when designing the shale shaker system include flow rate, fluid type, rig space, configuration power, available elevation, and discharge dryness (restrictions). Most programs extrapolate laboratory-generated performance curves to predict field performance. Unfortunately, laboratory-manufactured drilling fluid does not duplicate properties of drilling fluid that has been used in a well. High shear rates through drill bit nozzles at elevated temperatures...

Causes of Premature Screen Failure

Several factors may contribute to premature screen failure. Most failures result from improper screen installation or damage to the shaker itself. Cracked or warped shaker beds, which may result from many years of continuous use or improper maintenance, will cause poor vibration patterns. This may cause improper solids conveyance, which, in turn, may cause solids to gather on certain areas of the screen, wearing holes in that section. Damaged beds may also affect the tensioning ability of the...

I I

N Mesh count, number of wires per inch The above equation indicates that screens with the same mesh count may have different size openings depending on the diameter of the wire used to weave the screen cloth. Smaller-diameter wire results in larger screen openings, thereby allowing larger particles to pass through the screen. Such a screen will pass more drilling fluid than an equivalent mesh screen made of larger-diameter wires. In summary, specifying the mesh count of a screen does not...

Cut Points

Cut points are used to indicate the performance of solids control equipment. Cut point curves are determined by examining the mass of a variety of size ranges that are discarded relative to the same mass and size range presented to the removal equipment. Curves can be calculated by determining the ratio of the mass flow rate of solids within each size range in the discard stream, divided by the mass flow rate of solids of the same size range in the input stream. Cut points for shale shakers may...

Nonoilfield Drilling Uses Of Shale Shakers

Trenchless drilling is one of the fastest growing areas for shale shaker use other than drilling oil and gas wells. Trenchless drilling encompasses several areas of use Micro-tunneling Micro-tunneling has become very popular in Europe and is being used more frequently in the United States. Micro tunneling is the horizontal boring of a large-diameter hole (from 27 inches up to 10 feet) while simultaneously laying pipe. Typically, this technique is used in cities when laying or replacing water...

Separate unit

The separate unit system mounts usable rig shakers (elliptical or circular motion) on stands above newly installed linear motion shakers (Figure 4-2). Fluid from the rig shakers (or scalping shakers) is routed to the possum belly (back tank) of a linear motion shaker. Line size and potential head losses must be considered with this arrangement to avoid overflow and loss of drilling fluid. This design may reduce overall cost by using existing equipment. This concept, where space is available,...

Shaker Description

The majority of shale shakers use a back tank (commonly known as a possum belly or a mud box) to receive drilling fluid from the flow line (Figure 2-3). Drilling fluid flows over a weir and is evenly distributed to the screening surface (deck). The screen(s) are mounted in a basket that vibrates to assist the throughput of drilling fluid and the movement of separated solids, The basket rests on vibration Isolation members, such as helical springs or rubber float mounts. The vibration isolation...

Shaker Development Summary

Shale shakers have undergone many improvements since the last shale shaker handbook was published in the early 1970s. The current linear motion shakers, introduced in the 1980s, have become widely used because of their improved solids conveyance and fluid throughput. Balanced elliptical and linear motions make it possible to convey solids toward the discharge end of the deck while the screen is tilted uphill. The uphill tilt of the deck creates a pool of fluid at the feed end of the deck,...

Shale Shaker Design

The purpose of a shale shaker is to induce drilling fluid to flow through a screen, transport solids across a screen surface, and discharge solids off the end of the screen. Screening is the result of using the energy developed by a rotating eccentric mass and applying that force to a porous surface. The energy causes the screen to vibrate in a fixed orbit or path. The elements of shale shaker design focuses on several aspects of the machine Shape of motion (orbit or path) All of these...

Shale Shaker Screens

Shale shakers remove solids by processing solidladen drilling fluid over the surface of a vibrating screen. Particles smaller than the screen openings pass through the screen along with the liquid phase of the drilling fluid. Larger particles and trapped finer particles are separated into the shaker overflow for discard. The original criterion for early shale shaker screens was a long screen life. This demand for screen life was consistent with shaker designs and solids removal philosophies of...

Single Purpose Centrifugal Pumps

Solids removal equipment should be installed so that operation is straightforward and consistent. There should be a single starter (for an electric motor) or a single diesel engine for each pump. Manifolding of suction or discharge lines rarely results in effective equipment performance. Funds normally used for valves in a do-anything manifold, should be used to store an extra pump and motor in case of failure. Pumps and motors should be mounted so that they are easy to install and maintain....

Solids Control Equipment

Adequate solids control should be instituted at the beginning of any drilling operation due to the detrimental effects of drilled solids discussed in earlier chapters. Drilled solids will erode, disperse, and subdivide into smaller and smaller sizes as they recirculate in the system. Smaller drilled solids create many problems and are increasingly more difficult to remove. Once this process begins, it is impossible to eliminate the solids unless a large quantity of drilling fluid is jettisoned...

Suction And Testing Section

The suction and testing section is the last part of the surface system. Most of the usable surface volume should be available in this section. Processed and treated fluid is available for various evaluation and analysis procedures just prior to the fluid recirculating downhole. This section should be mixed, blended, and well stirred. Sufficient residence time should be allowed so that changes in drilling fluid properties may be made before the fluid disappears downhole, Vortex patterns from...

Their application is primarily during fast, tophole drilling, or in gumbo formations. This system was designed to handle high solids loading, which occurs when rapidly drilling large-diameter holes or when...

The Centrifugal Pump

A centrifugal pump is a rotating vane, or impeller, within a chamber. This pump increases the pressure of a liquid passing though it by increasing the velocity. Liquid enters the pump at the suction flange and revolves along the rotating impeller vanes until thrown to the inner surface of the chamber. Liquid flows from the tip of the rotating impeller along the inner circumference through the pump discharge. If a long, open-ended pipe is connected to the pump, the impeller causes fluid to move...

Three Dimensional Screen Panels

Three-dimensional screen panels were introduced in the mid-1990s. These typically offer more screening area than flat-panel, repairable plate screens while retaining the ability to be repaired. This type of screen panel adds a third dimension to the previous two-dimensional screens. The screen surface is rippled and supported by a rigid frame. Most three-dimensional screen panels resemble the metal used in a corrugated tin roof. Construction consists of a corrugated, pretensioned screen cloth...

Total Dynamic Head

The total dynamic head is the sum of total suction lift plus total discharge head. The sum of the gauge pressure head and the velocity head at the discharge flange, minus the sum of the corresponding heads at the suction flange, equals the energy (in foot-pounds) added per pound of liquid pumped. This is called the total head developed by the pump and is expressed as hgd Discharge gauge head hvd Discharge velocity head hgs Suction gauge head h Suction velocity head The discharge head of a...

Cost of Removing Drilled Solids

Few wells can be drilled without removing drilled solids (see Chapter 1). Even for 3,000- to 4,000-foot wells, problems created by drilled solids, such as lost circulation, stuck pipe, or well control, are more than enough reason to properly process the drilling fluid. In expensive drilling operations, the proper use of solids removal equipment will significantly reduce costs. Although drilled solids can be maintained by simply diluting the drilling fluid to control their acceptable levels or...

Common Screen Cloth Weaves

Some of the common cloth weaves available to the petroleum industry are shown in Figure 6-1. The plain square weave, plain rectangular weave, and the modified rectangular weave are the only screen cloths commonly used in the drilling industry. The twilled square weave is used for coarser screens in the mining industry (Figure 6-1B). The plain dutch weave, mostly used as a filter cloth, has small, triangularly shaped screen openings that allow very little fluid to flow through (Figure 6-1C). The...

Commonly Used Oil Field Pumps

A reciprocating pump is a positive-acting, displacement pump, which creates flow by displacing liquid from a cylinder or cavity with a moving member, or piston. Each chamber, or cylinder, is filled and emptied by the mechanical motion of a piston that alternately draws-in and then expels liquid. Available horsepower and the strength of the pump's structural parts determine pressure capabilities. Volume, or capacity, delivered per stroke by a reciprocating pump is constant regardless of...

Screen Blinding

Screen blinding occurs when grains of solids being screened lodge in a screen hole. This often occurs when drilling fine sands, such as in the Gulf of Mexico. The following sequence is often observed during screen blinding 1. When a new screen is installed, the circulation drilling fluid falls through the screen in a short distance. 2. After a time, the fluid endpoint travels to the end of the shaker. 3. Once this occurs, the screens are changed to eliminate the rapid discharge of drilling mud...

Total Dynamic Suction Lift

Total dynamic suction lift is the sum of two parameters 1. Vertical distance of pump above liquid (static suction lift) 2. Friction loss in suction pipe For example, if it is determined that friction losses are equivalent to five feet of head for fluids of water-like viscosity, the vertical distance of the centrifugal 'imp suction above the liquid level cannot exceed ten feet. When pumping viscous fluids, the pump suction should be below the suction tank. In other words, the head that moves...

Separation Potential

The separation potential analysis determines an ellipsoid volume that fits in each of the screen openings. The length and width of 1,500 openings in multiple-layered screens and 750 openings in single-layered screens are measured, and an ellipsoid volume is calculated for each opening with the following equation (Figure 6-5A) where Ve Volume of the ellipsoid (microns1) la Length of major axis (microns) lb Length of minor axis (microns) The diameter of a sphere having the same volume (Figure...

How A Shale Shaker Screens Fluid

Shale shakers should remove as many drilled solids and as little drilling fluid as possible. These dual objectives require that cuttings or drilled solids convey off the screen while simultaneously separating and removing most of the drilling fluid from the cuttings. Frequently, the only stated objective of a shale shaker is to remove the maximum quantity of drilled solids. Disregarding the need to conserve as much drilling fluid as possible defeats the ultimate objective of reducing drilling...

Removal Section Arrangement

All of the compartments, except three, use bottom equalizers. The sand trap should overflow into the next compartment downstream, which provides an opportunity for the solids to settle. Obviously, to increase residence time to allow settling, the drilling fluid should enter the sand trap as close to the upstream compartment wall as possible. Sand traps are very effective when water or seawater are used as drilling fluid. When drilling fluids are treated to provide a large value of the...

Inch Hydrocyclone For Special Applications

This cyclone is designed to make a very fine separation at a constantly high feed solids content. Although it operates in spray discharge, it is designed on the very wet side of balance.

The pressure in the suction line, if the pump is above the liquid level in the suction tank, may be less than atmospheric. Large friction losses in the suction lines to a centrifugal pump may also...

Selection Of Shale Shakers

The first consideration in selecting a shale shaker is to decide whether or not a gumbo slide, or gumbo-removal device, will be needed. This is often necessary when drilling recent sediments. A scalping shaker must be considered next. Scalping shakers are usually needed when large quantities of drilled solids or gumbo reach the surface. Usually, long intervals of 17 y-in.-diameter holes, with flow rates above 1000 gpm, require scalping shakers in front of fine mesh screens see Chapter 7 . The...

Vibrating Systems

The type of molion imparled to the shaker depends on the location, orientation, and number of vibrators used. In all cases, the correct direction of rotation must be verified. Circular molion shakers use a single vibrator mounted at the shaker's center of gravity. Belt-driven vibrators and hydraulic-drive vibrators are used for this shaker design. Unbalanced elliptical motion shakers use a single vibrator mounted above the shaker's center of gravity. Integral vibrators, enclosed vibrators, and...

Piping And Equipment Arrangement

The most common problem on drilling rigs is inadequate fluid routing, which allows drilling fluid to be processed through the equipment in a sequential manner. When a substantial amount of drilling fluid bypasses a piece of solids removal equipment, drilled solids cannot be removed.

For many drilling rigs, a set of Picenco SILTMASTERS large enough to process slightly more than the total circulating rate will handle the solids load below good screens. However, they will...

Carrying Capacity

One important component of a good solids management philosophy is the drilling fluid carrying capacity. As drilled solids sloughings and drill bit-generated enter the wellbore, they should be brought to the surface as soon as possible. If these drilled solids are tumbled and slowly brought to the surface, they have time to disintegrate and increase the low-gravity solids content of a drilling fluid. Suprisingly, drilled solids also affect the drilling fluid properties that control carrying...

Drilling Fluid Costs

Drilling fluid density can be increased using drilled solids for the lowest initial weight-up cost. If drilled solids had no other effect, using them for a weighting agent would be cost-effective. However, using drilled solids could potentially increase drilling costs because slow drilling, poor cement jobs, stuck pipe, and lost circulation will frequently follow. Downtime on a rig or reduced penetration rates are far more expensive than the cost of using adequate weighting material. Removal of...

Comparison And Analysis Of Shale Shaker Performance

Evaluation and comparison of two or more shale shakers, although seemingly a straightforward process, is difficult to accomplish and may yield false results. The process requires a methodical procedure, accurate sampling, and control of all variables involved in the analysis. Many reasons exist for analyzing shale shaker performance, ranging from legal analysis to objective comparison of different shakers. Regardless of Offset comparison combines information from more than one test to determine...

Dewatering Unit

More and more rigs are incorporating dewater-ing units in their drilling fluid treatment process. Dewatering units are designed to inhibit free liquid discard. The units can process drilling fluid from the active system or discard material from the solids removal equipment shakers, desanders, desilters, and centrifuges . Chemical pH adjustments, flocculants, and coagulants are added to the input stream of the dewatering unit. The solids are usually removed with a centrifuge. Colloidal-rich...

Double Deck Shaker

Baroid's new Double Deck Shaker provides the latest advancement in the control of drilled solids. Two screens are employed, usually a 30 mcsli on top with an 80 mesh below. The unit employs a gyrating motion rattier than the simple shaking motion of regular shale shakers. This motion keeps the solid particles moving toward the discharge end and helps prevent plugging of the screens. Maximum capacity of the unit is 12 barrels of mud per minute. Recommended power supply is three-phase 220 volts,...

Stokes Law For Fluid In Fluid

The D50 cut point of a solids separation device is defined as that particle size at which one-half of the weight of specific size particles go to the underflow and one-half of the weight go to the overflow. For example, a D30 cut point references a particle size which is 30 concentrated in the underflow and 70 in the overflow. As stated earlier, the cut point is related to the inside diameter of the hydrocyclone. For example, a 12-inch cone has a D50 cut point for...

Mud Cleaners

Until the development of linear motion shale shakers, an 80-mesh screen was about the finest screen that could process drilling fluid at a rig. With this limitation, drilled solids smaller than 177 microns remained in the drilling fluid. The mud cleaner was originally designed to remove drilled solids from a weighted drilling fluid in sizes ranging from 177 to 74 microns 200 to 80 mesh . Because barite is generally ground so that the majority is smaller than 74 microns, most of it should pass...

Sweco Round Mud Cleaner

Drilling fluid was used in the mid-1800s in cable tool percussion drilling to suspend the cuttings until bailed from the drilled hole.1 With the advent of rotary drilling in the water well-drilling industry, drilling fluid was well understood to cool the drill bit and to suspend drilled cuttings for removal from the wellbore. Clays were being added to the drilling fluid by the 1890s and by the time Spindletop was discovered in 1901, it was considered necessary to have suspended solids clays in...

Conclusions

Hydrocyclones are simple, easily maintained mechanical devices without moving parts. Separation is accomplished by transfer of kinetic input, or feed energy, into the centrifugal force inside the cone. The centrifugal force acts on the drilling fluid slurry to rapidly separate drilled solids and other solid particles in accordance with Stokes' Law. The solids generated while drilling in some formations are too fine for shale shakers to remove. Partially plugged feed inlet or outlet remove cone...

Dilution

Dilution is the surface addition of base fluid to the drilling fluid system. This addition has the effect of reducing the concentration of all other components or constituents of the drilling fluid. Although the shale shaker frequently removes a larger fraction of drilled solids, it should be regarded as only one component of solids removal equipment in a drilling fluid processing system. In addition to solids removal equipment, the detrimental effect of drilled solids can be reduced with...

Screen Conductance and Flow Capacity

A screen that enables an extra-fine separation is useless in the drilling industry if it will not pass a high volume flow rate. The amount of fluid that a screen will process is dependent on the screen construction, as well as solids conveyance, solids loading, pool depth, deck motion and acceleration, drilling fluid properties, and screen blinding. Although it is difficult to calculate the expected fluid processing capacity of a shaker, screens can be ranked according to their ability to...

The Evolution Of Solids Separation Devices

Cascade Shale Shaker

As mentioned previously, during the 1920s, the oil well drilling industry recognized the need to remove cuttings from the drilling fluid. The mining industry used stationary, vibrating screens for classifying larger pieces of ore from smaller pieces. These screens were adapted to separate cuttings from the drilling fluid in an evolutionary process, which has continued through time to yield the sophisticated solids control systems used today. The early machines were called screens not shakers,...
