Our high-pressure water jet lateral horizontal drilling technology is classified as fifth-generation radial horizontal drilling technology. After more than thirty years of development, HPT has successfully overcome the barriers of technology advancement, bringing this technology to a mature and practical level.
This method utilizes high-pressure water jetting to create lateral horizontal holes within existing wellbores. It allows for multiple operations to achieve several branching lateral horizontal holes.
Technical Advantages
Enhances oil production through lateral hole creation.
Increases exposed reservoir area and extraction pathways.
Connects natural fractures and untouched reservoir spaces.
Achieves cost-effective oil and gas output improvements.
Revolutionary method for aging oil field production.
Resumes operation of many abandoned wells.
Advantages Compared to Previous Technologies:
Cost saving due to simplified operations.
