METAL MUNCHER cutters milled packer in 4 hours, retrieved fish in one trip
A customer in northern Oklahoma needed to retrieve a permanent production packer that preset 1,700 ft (518.16 m) from the surface. Completion of the well was being held up and the project would soon be behind schedule. For that reason, the operator required the packer be removed in the same trip as it was milled, and that the packer be milled in the quickest way possible.
To meet the customer’s requirements, Baker Hughes, a GE company (BHGE), deployed the Quick Pick™ milling assembly dressed with industry leading METAL MUNCHER™ advanced milling technology (AMT) carbide. The packer had a 6-in. outside diameter (OD) extending 20 in. from the start of the packer to the slips, and an inside diameter (ID) of 3.875 in. with an alternate bore of 5 in. extending 17.5 in. from the top.
The Quick Pick assembly allowed for the packer retrieval spear to be engaged while the mill was rotating on the packer so that when the slips were milled over, the packer would not fall. In addition, the complete fish could be retrieved to surface in a single run. During milling operations, the robust packer mill reduces spinning on packer components such as rings and cones.
