  • Patent number: 11111748
    Abstract: Milling systems, tools, and methods include using a mill with secondary attrition system to re-mill cuttings and other debris away from the face of the mill. The secondary attrition system may be located uphole of the mill may be used to stage conditioning and re-sizing of debris. After debris is generated by the mill, the secondary attrition system may re-mill the debris to a finer size before allowing the debris to pass out of the sleeve. The debris may be re-milled by secondary cutting elements while within an annular gap positioned radially between the sleeve and a drive shaft for the mill. The annular gap may have a variable width as a result of a tapered outer surface of the drive shaft and/or a tapered inner surface of the sleeve. The variable width may cause debris to be re-milled into increasingly finer sizes.

  • Patent number: 11098563
    Abstract: A perforating gun apparatus comprising a bulkhead connector located between an upper gun body thread and lower gun body thread. The bulkhead connector has seals in sealing arrangement with an upper gun body and a lower gun body with a support sleeve in contact with an inner groove support shoulder on the lower gun body. The support sleeve is radially deformable into the inner groove by a shockwave produced by firing the charges in the lower gun section. The deformation of the support sleeve attenuates the impact of the shockwave on the threaded connection. The bulkhead connector isolates the threaded connection from the pressure spike. The deformed support sleeve attenuates the shockwave from the charges firing in the upper gun section and transfers the resultant force away from the threaded connection.
