Abstract
A gravel packing assembly has first and second joints each including a sand control screen assembly having a filter medium positioned exteriorly of a base pipe and a slurry delivery subassembly positioned exteriorly of the sand control screen assembly. The slurry delivery subassembly includes at least one transport tube extending longitudinally along at least a portion of the sand control screen assembly. At least one jumper tube is coupled to and extends between the at least one transport tube of the first joint and the at least one transport tube of the second joint. A jumper tube protection assembly extends between the first and second joints and is positioned exteriorly about the at least one jumper tube.
Claims14
A gravel packing apparatus comprising:
- first and second joints each including a sand control screen assembly having a filter medium positioned exteriorly of a base pipe and a slurry delivery subassembly positioned exteriorly of the sand control screen assembly, the slurry delivery subassembly including at least one transport tube extending longitudinally along at least a portion of the sand control screen assembly and extending through a ring assembly positioned around the base pipe;
- at least one jumper tube coupled to and extending between the at least one transport tube of the first joint and the at least one transport tube of the second joint;
- and
- a cage assembly extending between and coupled to the ring assemblies of the first and second joints and positioned exteriorly of the at least one jumper tube.

A method for assembling a gravel packing apparatus, the method comprising:
- providing first and second joints each including a sand control screen assembly having a filter medium positioned exteriorly of a base pipe and a slurry delivery subassembly positioned exteriorly of the sand control screen assembly, the slurry delivery subassembly including at least one transport tube extending longitudinally along at least a portion of the sand control screen assembly and extending through a ring assembly positioned around the base pipe;
- threadably coupling the sand control screen assembly of the first joint to the sand control screen assembly of the second joint;
- coupling at least one jumper tube between the at least one transport tube of the first joint and the at least one transport tube of the second joint;
- and
- coupling a jumper tube protection assembly to the ring assemblies of the first and second joints including forming a cage assembly by circumferentially distributing a plurality of plate members having gaps therebetween exteriorly around the at least one jumper tube.

A method for assembling a gravel packing apparatus, the method comprising:
- providing first and second joints each including a sand control screen assembly having a filter medium positioned exteriorly of a base pipe and a slurry delivery subassembly positioned exteriorly of the sand control screen assembly, the slurry delivery subassembly including at least one transport tube extending longitudinally along at least a portion of the sand control screen assembly and extending through a ring assembly positioned around the base pipe;
- threadably coupling the sand control screen assembly of the first joint to the sand control screen assembly of the second joint;
- coupling at least one jumper tube between the at least one transport tube of the first joint and the at least one transport tube of the second joint;
- and
- coupling a jumper tube protection assembly to the ring assemblies of the first and second joints including forming a cage assembly by circumferentially distributing a plurality of bowsprings having gaps therebetween exteriorly around the at least one jumper tube, the bowsprings having an outer diameter greater than an outer diameter of the first and second joints.
