摘要： A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.

摘要： 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.

摘要： An integrated sandface completion tool that can be positioned within a wellbore in a single trip and a method of providing a sandface completion in a wellbore. An embodiment of the integrated sandface completion tool includes a casing section having a casing wall, at least one explosive charge connected to the casing wall, and a screen assembly connected within the casing section forming a screen-casing annulus, the screen assembly having openings formed along a portion thereof and a port in selective communication with the screen-casing annulus. The method includes the steps of positioning the integrated completion tool in the wellbore, detonating the explosive charge and packing the screen-casing annulus with a material.
