Abstract
An apparatus for attaching a sand-control screen jacket to a base pipe comprising a base pipe connector securably engaged with the sand-control screen jacket, an internal slip member slidably disposed between the base pipe connector and the base pipe and a jam nut securably engaging the base pipe connector such that the internal slip member slides toward the base pipe connector increasing the friction between the internal slip member and the base pipe, thereby securing the sand-control screen jacket to the base pipe. The base pipe connector may further comprises a plurality of sealant ports through which sealant is injected affecting an additional seal between the base pipe connector and the base pipe. The sealant ports may accept a lock pin therein after sealant is injected.
