ABSTRACT:
A tubing connection arrangement that includes two expandable tubing sections is disclosed. In one embodiment, each of the tubing sections includes a filter screen sandwiched between inner expandable tubing and outer expandable tubing. On expansion of the tubing sections, the outer tubing provides resistance to radial expansion of the inner tubing in order to ensure that the integrity between the tubing sections is maintained. The filter screen of one of the tubing sections overlaps the filter screen of the other tubing section, and the outer expandable tubing of at least one of the tubing sections extends over the overlapping filter screens.
