Lateral Hydraulic Drilling (LHD)

• The technology uses a continuous flexible tubing to enter existing vertical wells and use high pressure hydraulic jets to drill horizontal bores.
•  To open a 20mm window in the reservoir with a small bit
•  The horizontal bores are 2.5”（6.35 cm）in diameter and up to 320’（96.35 m）in length.
•  It can drill multiple levels of oil bearing layer.
• The system is compact and simple to use.

Technical Advantage

Oil production:

• Increase the original borehole radius and discharge area
•  Reduce the oil flow resistance;
• Deep deplugging;
• Control the water coning and gas coning

Water injection:

• Achieve directional water;
• Reduce water injection pressure
• Improve the effect of water injection

Production improvement

• Deep acidification;
• Reduce the pump pressure of fracturing
• Effectively  relieve damage near wellbore area
• Increase oil discharge area
