Abstract: A technique facilitates connection of tubing strings in which one tubing string is received in another tubing string. A connector has an inner connector which may be coupled with an inner tubing string and an outer connector which may be coupled with an outer tubing string. The inner connector is sealingly received in the outer connector and releasably held within the outer connector by a releasable member. The construction of the connector enables selective release of the inner connector from the outer connector by applying a suitable force.

Abstract: An assembly is disclosed which is usable with the well which comprises a base pipe having a plurality of apertures where each of the apertures contains a screen insert. The assembly also includes a plurality of perforating charges which are mounted to the outer surface of the base pipe in proximity to the screen inserts. In one embodiment, the perforating charges are conical shaped charges, while in another embodiment, the perforating charges are linear shaped charges. An assembly according to the present invention may be utilized to perforate and gravel pack one or more of downhole zones in a single trip downhole. Utilization of linear perforating charges avoids killing the well and prevents formation damage by kill-pills or kill-fluids. An assembly in accordance with the present invention thus reduces drilling time and costs and allows for total flexibility for the distance between stacked intervals.
