Abstract: A water filtration system with a filter and method for filtering raw water having a series of media layers in the following order: 1) sand to gravel or coarse silica; 2) zeolite; 3) activated carbon; 4) a second layer of sand to gravel or coarse silica; and 5) a second layer of zeolite is disclosed. Optionally, the series further has a ceramic media layer, which may have a reactive coating such as calcium hypochloride. Further options include ferruginous latertic clay spheres (FLCS) or iron oxide brick particles, at least one grid, which may be charged, and/or at least one sand arch. A rapid sand filter may be used prior to filtering water through the series of media layers. The water may also be further filtered through a mixture of zeolite and carbon. Chlorine may be added to the filtered water. Specialized water filters for reducing fluoride and arsenic concentrations and taste aesthetics are also disclosed.

Abstract: A completion involving expandable tools and/or tubulars involves running the assembly downhole in a single trip. The expansion can take place using a swage or inflatable or other expansion techniques. The assembly can be delivered on production tubing so that upon conclusion of the expansion and the setting of any hangers and barriers production or injection can proceed from a pre-selected zone or zones.

Abstract: Several downhole flow control devices are disclosed which are meterable and are also capable of shutting of a particular zone in a well. The several embodiments include a multiple valve body, a toroidal inflatable valve, and a series of related choke systems. The downhole flow control choke mechanisms each include a downhole electronics package to provide programming or decision making capacity as well as motor actuation systems. Each choke mechanism also includes a system whereby the device can be converted to manual operation and actuated by a conventional shifting tool.

Abstract: A well control valve assembly having a downhole portion with a primary valve, and electromechanical actuator connected to the valve and a first wireless communicator connected to the actuator. The assembly further includes an uphole portion having a pump, a second wireless communicator complementary to the first wireless communicator and being supported in the uphole portion of the valve assembly. The downhole portion and uphole portion are physically non-connected and informationally connected.

Abstract: A system adapted for controlling and/or monitoring a plurality of production wells from a remote location is provided. This system is capable of controlling and/or monitoring: (1) a plurality of zones in a single production well; (2) a plurality of zones/wells in a single location (e.g., a single platform); or (3) a plurality of zones/wells located at a plurality of locations (e.g., multiple platforms). The multizone and/or multiwell control system of this invention is composed of multiple downhole electronically controlled electromechanical devices and multiple computer based surface systems operated from multiple locations. Important functions for these systems include the ability to predict the future flow profile of multiple wells and to monitor and control the fluid or gas flow from either the formation into the wellbore, or from the wellbore to the surface.
