Independent artificial lift company headquartered in<br />
Aberdeen, Scotland.<br />
Backed by 6 venture capital companies<br />
<strong>Who</strong> <strong>is</strong> <strong>ZiLift</strong><br />
“Bringing the latest technology into the artificial lift<br />
market” - Fluids are lifted using a pump driven by a<br />
Permanent Magnet motors - linear or rotational<br />
Granted patents using Permanent Magnet<br />
technology in a downhole environment<br />
Linear Concept
Value Proposition<br />
• Rig-less solutions – significantly reduced installation costs<br />
• State of the art Permanent Magnet motors – highest force density<br />
(flow/ depth) and enhanced reliability<br />
• Small diameter pump-motors – enable new options/ configurations<br />
for artificial lift solutions<br />
• Integrated monitoring & control – enables remote production<br />
optim<strong>is</strong>ation and autonomous system control<br />
• Open up unserved markets such as gas-well deliquification<br />
Ex<strong>is</strong>ting projects supported by major Oil & Gas operators<br />
All projects - field trials in customer wells in 2012/2013<br />

kickStart concept for well starting.<br />
Replacement for coiled tubing and gas lifting, eliminating;<br />
• crowded decks, heavy lifts and large crews<br />
• high pressure surface pumping, cryogenic hazards<br />
A bottomhole assembly including:<br />
Well intervention;<br />
• Safer<br />
• Faster<br />
• Better<br />
– Proven pumping technology<br />
– Zi-Lift low power / high efficiency PMM<br />
– Pump protector<br />
– Downhole sensor package<br />
– Retrievable packer & flow control<br />
