BARITE RECOVERYPROVEN THROUGH PERFORMANCE

OUR SUCCESSFUL PROCESS

Kayden Industries Total Optimization System (TOS) increases value to clients by

continually optimizing and improving operations in barite recovery applications.

The TOS program begins with pre-planning and design of a proper solids

control program from start to finish. The dedicated TOS team works with the

client to understand their unique drilling program, challenges and concerns. The

TOS team then tailors the equipment setup and performance tracking plan for

the drilling programs entirety.

The TOS team works closely with the technicians onsite to ensure the

equipment is continually optimized. The TOS team then tracks performance

daily, by well section, by well, and quarterly. Continually communicating results

and optimization changes to the client.

The TOS program is not only made up of dedicated barite recovery staff, but

is complemented with solids control equipment built for barite recovery. One

of the most important parts of the barite recovery program is the Bear-2276

centrifuge, which is a large bowl centrifuge built for barite processing. The Bear-

2276 combines the high capacity of Kayden’s Mammoth-2276 with a patent

pending internal design. This design creates a proper mixture of centrifuged

barite and polished fluid that is then introduced back to the active system. This

design creates a solution to the costly problems associated with poor barite

mixing and recovery. All Kayden equipment is adjustable and can be optimized

in real-time to ensure that processing and recovery are always optimized.

Kayden’s barite recovery process can be operated and optimized 24/7, which

allows for continued operation during drilling.

Kayden Industries is the leading innovator in Barite Recovery,

and has proven performance throughout all major North American

oilfield basins. With a continual optimization approach, Kayden

has been able to outperform the competition and show true cost

savings to operators across the industry.

KAYDEN ADVANTAGE

TRUE BARITE CENTRIFUGES

The Kayden process begins with the use of either the Mammoth-2276 or

Bear-2276 as the recovery centrifuge. These machines have a VFD panel

which allows optimization by the technician on-site, so the speed of the

centrifuge and the flow of the feed pump can be adjusted. Kayden centrifuges

also have adjustable pool plates, that when combined with the VFD panel

allows the technician to make multiple adjustments and optimize the amount

of barite recovered.

WASH-DOWN

The effluent or fluid from the barite centrifuge (overflow) is discharged into a

cone tank after the barite has been removed. The recovered barite (underflow)

is then discharged into a hopper that is positioned directly under the centrifuge

discharge with a wash-down pump rigged to it. This allows the barite to be

immediately mixed with fluid and discharged into the mud tanks. The wash-

down is rigged up to the rigs active system so that Kayden can ensure the

cleanest fluid is used.

TRAINING

Kayden field technicians are thoroughly trained through an in house mud

school and have hands on experience with barite recovery as trainees, before

working on their first barite recovery job. Throughout the job, technicians

optimize the equipment as well as capture samples which are then sent to

K-LAB (Kayden’s performance analysis and optimization service) for a detailed

analysis of the barite recovery equipment’s performance. The analysis is then

sent to the TOS team who analyze the data and communicate the findings and

offer optimization suggestions to the client.

POLISHING

The polisher process begins with the deweighted fluid (barite overflow)

being discharged into the cone tank, which the polishing centrifuge is

rigged up to. The polishing centrifuge can be either the Predator-2072 or

the Mammoth-2276. The polishing centrifuge has adjustable pool plates

and is controlled by the VFD to allow for continual optimization by the field

technicians, ensuring the best possible cut. The polisher overflow also

discharges into the cone tank. By following this process Kayden is able

to process the fluid multiple times before the fluid is reintroduced into the

rigs active system. This ensures the fluid is as clean as possible.

WASH DOWN PUMP AND BARITE RETURN

The intake for the barite recovery wash down pump is suction tank 1. The wash

down pump also discharges into suction tank 1. The wash down pump must

run constantly while the barite recovery process is in operation. Kayden uses

a barite recovery hopper to return the recovered barite to the active system.

The hopper and the wash down pump work similarly to a chemical mixing

hopper on the rig. The wash down pump and barite return assists by mixing the

recovered barite with fluid from the active system prior to being returned. It is

important that the suction for the wash down pump is in the same tank as its

discharge. The barite recovery hopper return is placed over a mud tank agitator

to ensure proper mixing is achieved.

INITIAL SUCTION AND BARITE RECOVERY

The suction for the barite recovery centrifuge is from the shaker tank. Barite is

discharged from the barite centrifuge underflow to the recovery hopper. Fluid

containing LGS is discharged through the barite centrifuge overflow to the

cone processing tank. The densities of the barite centrifuge overflow (LGS)

and underflow (HGS) are taken every 4 hours or as required. The density of

the overflow and underflow allows the technician to monitor the cut point of

the barite centrifuge. Given that centrifuges favor larger particles and particles

with a higher specific gravity Kayden can optimize recovery with our barite

recovery centrifuge by adjusting speed and pool plate settings. The Kayden

Mammoth-2276 and Bear-2276 centrifuges perform exceptionally well in

barite recovery.

SOLIDS PROCESSING AND CLEAN FLUID DISCHARGE

The suction for the polishing centrifuge is the cone processing tank. The fluid

from the cone processing tank is processed multiple times prior to its return

to the active system. The fluid is able to make multiple passes through the

polishing centrifuge due to the high processing rate of Kayden centrifuges

and the design of the cone processing tank. The densities of the polishing

centrifuge overflow (effluent) and underflow (LGS) are taken every 4 hours or

as required. The density of the overflow and underflow allows the technician

to monitor the cut point of the polishing centrifuge. Retorts are burned on

both the polishing centrifuge overflow and underflow once per shift or as

required. The retorts allow our technicians to see the percentage of LGS &

HGS returning to the system through the polishing centrifuge overflow. It also

provides information on the % of LGS, HGS, and oil being discharged down

the polishing centrifuge slide.

RECOVERED FLUID

Fluid recovered by either drying shakers or a vertical cuttings dryer is

pumped directly into the cone processing tank. The recovered fluid contains a

high percentage of solids. It is essential that the recovered fluid is clean prior to

its return to the active system. The design of the cone processing tank allows

for the fluid to pass through the polishing centrifuge multiple times before it is

returned to the active system.

PERFORMANCE TRACKING

The weights listed below are taken every 4 hours or as required.

They provide information on the performance of each centrifuge to

the technician and are a good data reference.

BARITE RECOVERY

1. Flowline

2. After the rig shaker

3. Barite centrifuge overflow

4. Polishing centrifuge overflow

5. Active system

6. Barite centrifuge underflow

7. Polishing centrifuge underflow

Samples 1 & 2 When comparing the results you can see the cut the rig shaker

is taking from the fluid.

Samples 3 & 4 show the cut between the barite and polishing centrifuges.

Samples 5 can be compared and shared with the derrickhand and mudman

as an additional density test on the active system.

Samples 6 & 7 are a good reference to be compared with Samples 3 & 4.

If your underflow weights are off then adjustments will need to be made

to the centrifuges by way of speed, pool plate settings, or flow rate. The

adjustments will change the cut points & weights of the centrifuge

effluents (overflow).

RETORTS - BARITE RECOVERY

Retorts are burned on the polishing centrifuge overflow (effluent) and the

polishing centrifuge underflow. The effluent retort is completed to calculate

the amount of LGS/HGS returning to the system via the polishing centrifuge

effluent. The underflow retort is completed to calculate the percentages of oil/

water & HGS/LGS in the polishing centrifuge underflow (cuttings) sample.

END OF WELL SAMPLES

All end of well samples are taken 500ft from TD.

PARTICLE SIZE ANALYSIS (PSA)

1. Flowline

2. After the rig shaker

3. Barite Centrifuge overflow

4. Polisher Centrifuge overflow

5. Active system

Samples 1 & 2 compare the particle size of returns from the flowline before and

after the rig shaker.

Sample 3 shows the particle size of the fluid processed by the barite recovery

centrifuge. The barite centrifuge is the 1st point of suction from the rig mud

tanks. Looking at the particle size in this sample allows us to see the low

density point of the particles recovered and the exact particle size of the barite

centrifuge overflow. It is important to recover as much barite as possible leaving

the low gravity solids to be removed by the polishing centrifuge.

Sample 4 shows the particle size of the fluid processed by the polishing

centrifuge. This is the last time the fluid is processed prior to being returned

to the rig.

Sample 5 shows the particle size distribution in the active system.

OIL ON CUTTING (OOC)

1. Rig shaker cuttings

2. Drying shaker/Vertical Dryer cuttings

3. Polishing centrifuge cuttings (underflow)

The oil on cuttings test accumulates results and provides the m3 of mud

discharged/ m3 of cuttings discharged, the % of whole mud retained on

cuttings, the % of oil by weight, and the % of oil by volume.

Sample 1 shows the results from the rig shaker cuttings.

Sample 2 shows the results from either the drying shaker or vertical dryer

cuttings allowing us to see the percentage of fluid recovered by the

drying process.

Sample 3 shows the results from the polishing centrifuge cuttings. This is a good

reference for fluid loss. Testing on the polisher centrifuge cuttings (underflow)

can be conducted to show the percentage of oil/water & HGS/LGS.
