Drilling & Workover Rig

  • Workover Rig
Features

As a world leading manufacturer of oilfield equipment, Jereh is dedicated to providing cutting-edge, reliable and customized drilling equipment including truck-mounted, trailer-mounted and marine drilling rigs (≤1000HP) and skid-mounted engine-driven land drilling rig (≤2000HP) with integrated solutions to achieve automatic control, easy and quick mobilization and cost saving.

Advantages & Features
• Intelligent control system
Jereh’s intelligent control system adopts PLC as the core and integrates drilling instruments and electrical control units to collect real-time signals for intelligent control of the rig and space saving in the driller room.
