International Classification:

C03B 37/025
C03B 37/029

Abstract:

A sensor system to provide data for use to control manufacture of an optical fiber in microgravity including a diameter sensor to monitor a diameter of a fiber drawn from a preform material, a tension sensor to monitor tension of the fiber as the fiber is pulled from the preform material to a storage device and a controller in communication with at least one of the diameter sensor and the tension sensor to evaluate sensor data to determine at least one of a speed and rate at which the fiber is pulled from the preform material.

E21B 33/128

Abstract:

In one aspect, a device for use in a wellbore includes a tubular body; a barrier member associated with an outer surface of the tubular body configured to retain a proppant; an actuating member associated with the barrier member configured to expand the barrier member in an annular direction; and a fluid channel associated with an upper extent and a lower extent of the barrier member, configured to allow a fluid flow therethrough. In another aspect, a method for completing a multi-zone wellbore, includes deploying a barrier device at a downhole location within the wellbore; expanding a barrier member in an annulus of the wellbore; providing proppant in the annulus of the wellbore; retaining the proppant in the annulus via the barrier member; and providing a fluid flow between an upper extent and a lower extent of the barrier member.
