Drilling Horizontal Wells with a Specialized Inclined Rig

Drilling with a specialized inclined drilling rig is a technology for constructing wells with an angle of inclination (from ~7° to 45°), designed for the efficient development of shallow reservoirs, as well as for sites where the use of traditional vertical drilling rigs is technically or economically impractical.

The type of rig used combines the functions of drilling, casing installation, and working with wellhead equipment at any angle of inclination, including the ability to install blowout preventers (BOP).

Wells with inclined wellheads are successfully operated using electric submersible pumps and rod pumping units.

🔸Technological Features

• Drilling with an inclined wellhead without constructing a vertical starter interval

• Operation in a depth range of approximately 100 m – 1,000 m vertically

• Ability to form extended inclined and horizontal sections

• Minimum radius of curvature of the borehole – suitable for conditions where standard drilling solutions are not applicable

• Compact base of the rig – minimal surface footprint

• Full operation with BOP and wellhead equipment at angles of 7°–45°

🔸Key Advantages for Resource Users

• Maximum contact with the exposed layer due to the inclined/horizontal profile

• Increased efficiency of development

• Expansion of the drained zone without drilling additional vertical wells

• Economically justified for low- and medium-yield fields

• Reduction of capital and operational costs

• Smaller drilling site dimensions

• Reduction of earthworks and infrastructure

• Ability to drill multiple boreholes from one site

• Expansion of drilling geography and conditions

• Drilling near cities, industrial zones, and protected natural areas

• Operation in coastal areas and complex terrains

• Access to deposits previously considered hard to reach
