Abstract: A gravel pack assembly gravel packs a horizontal borehole. Operators wash down the borehole using a tool in a first position by flowing fluid from the tool through the apparatus' toe. Operators then gravel pack by moving the tool to a first flow port between a screen and the toe. Slurry flows into the borehole from the first flow port, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. When the tool has a sleeve, operators can break any bridges by flowing fluid from the passage of the assembly into the tool. In another condition, operators can move the tool to a second flow port. Slurry can flow into to the borehole through a shunt extending from the second flow port. Meanwhile, returns can flow from the borehole through a bypass in the assembly.

Abstract: Proppants for use in fractured or gravel packed/frac packed oil and gas wells are provided with a contaminant removal component to remove one or more of the contaminants found in subterranean water/hydrocarbon from a production well. The water/hydrocarbon cleaning proppant solids may be used as discrete particles in a proppant formulation, as a coating on proppant solids in pores of a porous proppant solid or as part of the proppant's internal structure. The contaminant removal component removes contaminants, especially dissolved contaminants, in the subterranean water or hydrocarbon before the water/hydrocarbon leaves the well. For those contaminant removal components that can be regenerated, such as ion exchange resins, a measured quantity of an acidic regeneration solution can be injected into the fractured stratum for regeneration and recovered when the well resumes production.

Abstract: Described is a well completion for evenly distributing a viscosity reducing injectant (e.g. steam and/or solvent, e.g. in SAGD or CSS) into a hydrocarbon reservoir (e.g. of bitumen), for evenly distributing produced fluids (most specifically vapor influx) and for limiting entry of particulate matter into the well upon production. On injection, the injectant passes through a limited number of slots in a base pipe, is deflected into an annulus between the base pipe and a screen or the like, and passes through the screen into the reservoir. On production, hydrocarbons pass from the reservoir through the screen into a compartmentalized annulus. The screen limits entry of particulate matter (e.g. sand). The hydrocarbons then pass through the slots in the base pipe and into the well. Where a screen is damaged, the compartmentalization and the slots in the base pipe limit particulate matter entry into the well.

Abstract: A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer.

The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.
