Kraken System · Oil & Gas
Every Stroke.
Controlled.
Fluid pound destroys rod strings. Excess cycling burns equipment and cash. The Kraken System's integrated regenerative drive and pump-off control keeps every well running at the right speed — protecting your lift system and your bottom line.
The Problem
Traditional Control
Costs You.
A conventional pump-off controller does one thing when the well pumps off: it shuts the pump down, waits, and restarts it. Full speed or nothing — every cycle is a hard stop, an inrush start, and mechanical shock through the whole string.
- Fluid pound shocks the rod string every time the barrel runs dry
- Full-speed hard starts spike inrush and hammer the motor and gearbox
- On/off cycling drops production and stresses surface equipment
- Fixed timers keep pumping — or keep idle — regardless of real fillage
- VFD models that do slow down bleed braking energy off through a resistor as heat
The Solution
KRAKEN INTELLIGENT CONTROL.
Zero Downhole Hardware.
The Kraken System reads a real downhole dynamometer card — computed from surface load and rod position, the same proven method the best controllers use. But instead of shutting the pump off when fillage drops, the regenerative drive rolls speed down to match inflow. The pump keeps producing, the rod string never gets slammed, and braking energy goes back to the line instead of a resistor bank.
- Real-time downhole card from surface load + position — proven fillage detection, no downhole hardware
- Speed modulates to match reservoir inflow — the pump slows instead of stopping
- Fluid pound prevented — speed drops before the barrel runs dry
- Regenerative drive returns braking energy to the line — no DBR, lower kWh
- Cellular remote monitoring — full well visibility from anywhere
How It Works
Regenerative Energy Flow
01
Motor Generates
On deceleration the motor acts as a generator, converting mechanical energy to AC.
→02
AC Re-Enters
Generated AC power flows back into the output inverter.
→03
DC Bus Buffers
The DC bus holds and stabilizes the recovered energy.
→04
AFE Converts
The Active Front End converts stored DC into clean, low-harmonic AC.
→05
Returned To Grid
Clean AC is fed back to the utility instead of wasted as heat.

Capabilities
Built For The Field,
Not The Lab.
Integrated POC
Fully integrated pump-off control for maximum uptime and production.
Speed Modulation
The pump slows to match reservoir inflow instead of stopping. Production stays steady. Mechanical shock is eliminated at both ends of the rod string.
Fluid Pound Protection
By detecting low fillage before the pump runs dry, the Kraken System prevents the destructive hydraulic shock that causes rod failures and pump damage.
Dynagraph Display
Surface dynamometer card displayed on the HMI and accessible remotely — diagnose rod load, pump fillage, and mechanical issues without pulling the well.
Regenerative Energy
The active-front-end LH drive converts deceleration energy to clean, low-harmonic AC and returns it to the grid — eliminating braking resistors and saving energy.
Remote Uplink
Phase Connect lets you monitor, adjust, and troubleshoot every well in your field from a single dashboard — without leaving the office.
Motor Protection
A suite of integrated protections including overload, phase-loss, and over-temperature with configurable trip thresholds — guards the motor and extends equipment life in harsh field conditions.
UL 508A Listed
Every Kraken System panel is built in our Rapid City, SD facility under UL 508A listing — fully labeled, documented, and ready for installation inspection.

What's Inside
Products In The System
Every component in the Kraken System is a Phase Technologies product — designed together, integrated together, and supported together.
Core Drive
Active Front-End · Regenerative
LH Regen Drive
Low-harmonic, regenerative VFD — the power core of the Kraken System. Returns braking energy to the grid and meets IEEE 519 without external filters. Available 5–800 HP.
Remote Monitoring · Cellular
Phase Connect
Cellular-connected field monitor purpose-built for oil & gas. View dynagraph cards, adjust speed, and receive fault alerts from any well in your field — no Wi-Fi required.
Pump-Off Controller
Pump-Off Controller
A touchscreen interface gives you full visibility into your well — surface dynagraph cards, real-time pump diagnostics, motor load, and fillage trends all in one place.
Pump-Off Controller
Downhole Intelligence.
No Downhole Hardware.
The Kraken Pump-Off Controller calculates a full downhole card by solving the 1D wave equation — using directly measured surface load and position as boundary conditions. It knows what the pump is doing at the bottom of the well.
Sunlight-Readable Touch Screen
Color touch screen built for the field — readable in direct sunlight. On-site well management without squinting at a panel.
15-Minute Rapid Start
Enter a few parameters and the controller is live. Rapid Start gets your well running in under 15 minutes — no specialist required on-site.
Dynagraph Card Display
Full surface and downhole dynamometer cards on the keypad and remotely. Diagnose fillage, rod load, and mechanical issues without pulling the well.
