Drilling sidetracks, cutting “windows” and drilling “technological” pockets

Drilling sidetracks,  cutting “windows” and drilling “technological” pockets

Drilling sidetracks is a high-tech operation that allows you to restore or significantly increase the productivity of a well without drilling a new one. We provide services for cutting lateral wellbores by cutting a “window” and drilling a ‘technological’ pocket, including cutting a “window” in the casing string, drilling a technological pocket, and supporting subsequent operations for the construction of a new wellbore.

Cutting a “window” in the casing

Using modern whipstocks with mechanical or hydraulic anchors, as well as milling tools, we ensure accurate and safe formation of a window in the casing. Work is possible in horizontal and inclined directional wells, including in difficult conditions.

Drilling a technological pocket

After cutting the window, a technological pocket is drilled—a special extension outside the casing string that ensures a stable trajectory when drilling the lateral wellbore. A custom-designed cutter is used for this operation, taking into account the specific geological conditions.

We drill a new well with a controlled trajectory, aimed at bypassing problematic intervals and opening up new productive formations. The technology is particularly effective in the following cases:
– Flooding of the main well
– Mechanical damage to the column
– Depletion of formations
– The need to redevelop previously undrilled areas

Technical advantages:

• Use of high-precision whipstocks and milling cutters manufactured in-house
• 24/7 engineering support
• Operations are carried out in vertical, directional, and horizontal wells
• Comprehensive support for drilling, repair, and geophysical work

Result:

• Increased flow rate
• Significant reduction in the cost of constructing new wells
• Extended service life of the facility
• Increased oil/gas recovery rate
