摘要： An expandable downhole tool is disclosed that employs naturally occurring organic matter as the expandable material. The expandable material is located within an enclosure formed in part by an impermeable element, which may form a hydraulic seal, and a permeable membrane that permits fluids present in the wellbore to pass and interact with the organic matter. The heat and fluids present within the wellbore may cause the expandable matter to swell, and thus causing the enclosure to swell and possibly form a hydraulic seal against a wellbore or inner annulus. The expandable tool may be used as packer, plug, or other downhole tool, among others. Methods of manufacturing and using such tools are also disclosed.

摘要： A sensor used to determine the height of one or more fluids in a fluid column and to determine a location of an interface or boundary between a plurality of fluids in a fluid column is disclosed. The sensor includes a plurality of sensing elements comprising a capacitor and other components, such as resistors and inductors. The sensor also includes an oscillator that alters a frequency of an electrical current applied to the sensor, from which the dielectric constant of the fluid in which each sensing element is disposed can be determined. Methods of using such a sensor to determine the relative heights of various fluids in a fluid column are disclosed. In particular, methods of using embodiments of the invention in a well, such as water and petroleum wells, are described.
