METAL MUNCHER AMT milled high-yield casing, saved USD $1.25 million
A customer in Aberdeen needed to cut and mill a section in 9 ⅞-in. Q-125Hy casing at 13,120 ft (3999 m) cement plug placement. The casing was a high-yield strength material which is challenging to mill without damaging conventional cutting structures.
To cut and mill the section, Baker Hughes, a GE company (BHGE), deployed the Model D™ section mill designed for fast and efficient casing milling. The knives were dressed with special, industry leading METAL MUNCHER™ advanced milling technology (AMT) carbide to provide the robustness and enhanced cutting performance needed for faster milling and increased life.
Per standard operating procedures, a surface function test was conducted before tripping the bottomhole assembly (BHA) downhole to the cutting depth. When the section mill reached target depth, the string was rotated to begin cutting. A drop in surface pressure indicated that the cut had been successfully made.
