Abstract
An oil and gas downhole device is disclosed wherein the device separates the oil and gas from undesired water, which returns to the formation. The device includes a plurality of channels filled with elements fit tightly to a gas tight seal at atmospheric pressure with interstitial spaces. Under pressure the device allows oil and gas to pass but not water within its operating range of pressures. Also included is a method for using the device.
Claims14
An oil-field apparatus comprising:
- a cylindrical member with a central bore and a plurality of channels cut into an outer surface of the cylindrical member;
- a plurality of openings at the bottom of each of the plurality of channels, where each of the openings extends to the central bore;
- a plurality of elements disposed in each of the plurality of channels, wherein each of the plurality of elements has a length substantially the same as a length of its respective channel, wherein each of the plurality of elements is a cylindrical rod made of steel or stainless steel, and wherein the plurality of elements is arranged in at least two layers and fitted together to form a gas tight seal at normal atmospheric pressure;
- and
- a fastening means at each end of each of the plurality of elements to attach the plurality of elements to the cylindrical member;
- wherein the apparatus is suitable for disposition in a wellbore in a formation;
- and
- wherein (1) each of the cylindrical rods of the plurality of elements has a diameter, and the diameters of the cylindrical rods are non-uniform, (2) at least of the cylindrical rods of the plurality of elements is tubular, or both.

A method for producing gas and/or oil from a wellbore in a formation, the method comprising:
- flowing gas and/or oil from the wellbore through an apparatus connected to a tubing string disposed in the wellbore in an operating pressure range of the apparatus, where the apparatus comprises:
- a cylindrical member with a central bore and a plurality of channels cut into an outer surface of the cylindrical member;
- a plurality of openings at the bottom of each of the plurality of channels, where each of the openings extends to the central bore;
- a plurality of elements disposed in each of the plurality of channels, wherein each of the plurality of elements has a length substantially the same as a length of its respective channel, wherein each of the plurality of elements is a cylindrical rod made of steel or stainless steel, and wherein the plurality of elements is arranged in at least two layers and fitted together to form a gas tight seal at normal atmospheric pressure;
- wherein (1) each of the cylindrical rods of the plurality of elements has a diameter, and the diameters of the cylindrical rods are non-uniform, (2) at least of the cylindrical rods of the plurality of elements is tubular, or both;
- a fastening means at each end of each of the plurality of elements to attach the plurality of elements to the cylindrical member;
- and
- rejecting the flow of water through the apparatus to the well tubing string.
