Horizontal drilling process
First direct downhole oil drilling miners with a special bit called the mill regularly vertical drill pipe. oil desander grinding, and then deflected to the side of the casing above the bed of oil, cut into the well next to a window. Once the hole has been cut off, replaced the pipe assembly and mud motors in drilling vertical drilling. Unlike a long-term rigid pipe, the pipe string can be bent and curved horizontal drilling. Pipeline within the special probe on the surface of diamond can guide the mud motor drilling in the desired direction and angle. Once you start drilling, the miners set up a large frac tanks and trucks, high-pressure pump to the surface of the oil. The use of multi-pumping and storage in surface the fracturing Tankejialun oil pumped.

Use
The application of horizontal drilling technology, solid control system including thin oil the RIM reservoir utilization, expansion of the wells there are multiple drainage holes to prevent water / gas cone. It can also be used for drilling under buildings, roads and other places such as airports and highways. Horizontal well drilling technology can be used to transport between the liquid in the soil vapor extraction, vertical wells and sewage treatment facilities, and installed in the landfill gas collection system.

Benefit
Horizontal drilling has brought benefits, including increasing the production of vertical drilling up to 20 times or more. This can be done, because it has more contact with the reservoir. Notwithstanding the above, the factors of production, vertical drilling, horizontal drilling costs. According to the U.S. Department of Energy, oil drilling pipe horizontal drilling can also lead to an increase of 2% crude oil reserves in place. The ratio between the level of production wells vertical wells is 3.2 to 1, while the cost ratio is 2 to 1.
