Technology and equipment for window-cutting in cased and/or open hole well by application of one-trip whipstock with hydraulic anchor/packer

Advantages

One trip whipstock
Our whipstock, although very simple in design, provide a reliable anchor.
The use of our whipstocks allows the cutting of the window in casings without any cementing or similar operations with inclinations up to 100�.
The double mill cutter is reinforced with metal-ceramic composition and reinforced by alloy plates that make possible high-speed milling.
The use of our whipstocks makes possible window-cutting operations of only 4 to 8 hours, depending on casing thickness, casing steel grade, and inclination angle in the window-cutting interval.
