Abstract
An apparatus is provided comprising a first tubular having an inside surface and outside surface defining an outside diameter; a second tubular concentric with the first tubular, the second tubular having an inside surface defining an inside diameter greater than the outside diameter of the first tubular, an outside surface, and a longitudinal axis; a plurality of spacers between the first and second tubulars, each spacer having a longitudinal axis parallel to the longitudinal axis of the second tubular, wherein at least one spacer is hollow; and at least one data sensing device and/or at least one data collecting device and/or at least one data transmitting device is carried within the at least one hollow spacer.
Claims25
An apparatus comprising:
- a first tubular having an inside surface and outside surface defining an outside diameter;
- a second tubular concentric with said first tubular, said second tubular having an inside surface defining an inside diameter greater than the outside diameter of said first tubular, an outside surface, and a longitudinal axis;
- a plurality of spacers between said first and second tubulars, each said spacer having a longitudinal axis parallel to the longitudinal axis of said second tubular, wherein at least one said spacer is hollow;
- and
- at least one means for sensing data and/or at least one means for collecting data and/or at least one means for transmitting data carried within said at least one hollow spacer;
- wherein said means for sensing data is a Fabry-Perot interferometer cavity optic sensor device.
An apparatus for measurement comprising:
- a cylindrical shaped membrane having a longitudinal axis, said membrane comprising at least one wire wound helically around a plane parallel to said longitudinal axis, thereby forming a cylindrical shaped membrane having an inside surface defining an inside diameter and an outside surface defining an outside diameter, wherein at least one said wire is hollow;
- and
- at least one means for sensing data and/or at least one means for collecting data and/or at least one means for transmitting data carried within said at least one hollow wire;
- wherein said means for sensing data is a Fabry-Perot interferometer cavity optic sensor device.
A process for taking measurements in a well according to claim 15 wherein said means for transmitting data is selected from a communication cable, an electrical cable, an optic fiber cable, and combinations thereof.
A process for taking measurements in a well for taking measurements in a well, said process comprising:
- providing a wellbore;
- running means for sensing data and means for collecting data and means for transmitting data within an apparatus placed in the wellbore, said apparatus comprising a first tubular having an inside surface and outside surface defining an outside diameter, a second tubular concentric with and said first tubular, said second tubular having an inside surface defining an inside diameter greater than the outside diameter of said first tubular, an outside surface, and a longitudinal axis, and a plurality of spacers between said first and second tubulars, each said spacer having a longitudinal axis parallel to the longitudinal axis of said second tubular, wherein at least one said spacer is hollow, wherein said one means for sensing data and means for collecting data and means for transmitting data are carried within said at least one hollow spacer;
- sensing and collecting data depicting certain well conditions;
- and
- transmitting said data through said means for transmitting data;
- wherein said means for sensing data is a Fabry-Perot interferometer cavity optic sensor device.
A screen for use within a wellbore, comprising:
- a first tubular having an inside surface and outside surface defining an outside diameter;
- a second tubular concentric with and said first tubular, said second tubular having an inside surface defining an inside diameter greater than the outside diameter of said first tubular, an outside surface, and a longitudinal axis;
- a plurality of spacers between said first and second tubulars, each said spacer having a longitudinal axis substantially equal to and parallel to the longitudinal axis of said second tubular, wherein at least one said spacer is hollow;
- and
- at least one means for sensing data and/or at least one means for collecting data and/or at least one means for transmitting data carried within said at least one hollow spacer.
