KUDU PCPTRADITIONAL SIDE DRIVE SYSTEM
Patented Integrated Magnetic powder braking
system
For constant down hole pump stuck issues in Oman due to high sand, high wax and high viscosity, our patented Magnetic Powder Braking system can firmly stop THE SRD even power failure occurs, and THE SRD’s True Direct Drive design can prevent damages to wellhead equipment and danger to workers caused by backspin.China is planning to ban all side-drive PCP systems in 2019, because a lot of workers lives were taken by side-drive PCP systems.

1,695Nm/45Kw/Max.500rpm1. Power factor(Motor): 90.3%2. Avg. operating speed: 70 rpm/min3. Avg. current: 25 ~ 30 Amps4. Avg. Power consumption :
around 14.8 Kw ~ 17.9 Kw
1. Oilwell depth: 1,400 Meter2. Water cut: 8%3. Avg. productivity: 5 ~ 10 Ton/day (30 ~ 70 b/d)4. Avg. revolution for oil lifting equipment:70 rpm (idea for this oilwell condition due to high sandy
rate, it is easy to bring out the sand to cause equipment in surface and downhole if speed is over 70rpm.

operating speed. Increasing power consumption at
least 5 to 20% due to such mechanical conversion
Low starting current , high torque in low speed,
lower power motor (cost saving)
High starting current, low torque in low speed, higher
power motor is needed to provide more torque
Heavy oil: SRD starts at low speed with high torqueHeavy oil: PCP starts at full speed then slow
down,increasing power consumption, increasing costs
More cost for maintenance –

• There are approximately 5 million oil wells in the world, 600,000wells in China, of which about 60% are sucker rod pump (SRP)systems and 20% are conventional PCP systems.
• Any oil and gas well (including horizontal wells) with a maximumoutput of 400 b/d is suitable for THE SRD.
• Any oil and gas well with a maximum output of 220 b/d with highwater cut, low viscosity, low-sand and low-wax is suitable for THELESP.
• Each year, approximately 50,000 to 100,000 new oil wells are put intoproduction and all of which could be suitable for either THE SRD-2 orTHE LESP.
• Conventional Side-drive PCP system, which will be banned in Chinain 2019, companies such as Baker Hughes, Schlumberger, WaterfordInternational and Halliburton will be affected by this policy. However,we, the W&S Company, the only manufacturer of true direct drivesystems will benefit from the market shifting.
