A system is disclosed for communication from an instrument disposed in a wellbore. The system includes a flow diverter selectively operable to conduct fluid flow between a first path along the interior of a housing and a second path along the interior of the housing. The system includes an initiator operatively coupled to the flow diverter to cause selective operation thereof in response to an event.

Downhole fluid pressure signal generation and transmission

Apparatus for use in a wellbore comprises (1) a first structure that comprises (a) at least one extendable member that can be reconfigured from a coiled form to an extended form, the member having a flattened transverse cross-section when in the coiled form and a curved transverse cross-section when in the extended form, (b) a downhole well tool attached to the extendable member, and (c) a housing in which the extendable member can be coiled; (2) a well mounting device for supporting the first structure from the wellbore or the surface of a well; and (3) means for reconfiguring the extendable, coilable member in a wellbore from the coiled form to the extended form. Preferably, the extendable member is reversibly configurable between the coiled form and the extended form.
