Abstract

A inflow control device includes a housing. A filter media disposed in the housing. A closure member; and a spring disposed between the closure member and the filter media. A method for controlling fluid loss for a period of time.

First claim

What is claimed is:

1. An inflow control device configured for insertion in a wall of a tubular comprising:
a housing having a seat configured for installation in the wall of the tubular;
a filter media disposed in the housing;
a closure member radially outwardly disposed of the filter media in the housing;
a barrier disposed between the closure member and the seat, the barrier preventing fluid flow through the housing until the barrier is at least partially removed from the inflow control device; and
a spring disposed between the closure member and the filter media.

2. The inflow control device as claimed in claim 1 wherein the housing includes a recess that promotes flow around the closure member when the closure member is not seated.

3. The inflow control device as claimed in claim 1 wherein the barrier is dissolvable, degradable or disintegrable.

4. The inflow control device as claimed in claim 3 wherein the barrier is a controlled electrolytic metallic material.

5. The inflow control device as claimed in claim 3 wherein the barrier is a biopolymer.

6. The inflow control device as claimed in claim 1 wherein the filter media is a bead pack.

7. The inflow control device as claimed in claim 1 wherein the filter media is a foam.

8. The inflow control device as claimed in claim 1 wherein the closure member seals against an O-ring.

9. The inflow control device as claimed in claim 1 wherein the spring is a compression spring.

10. The inflow control device as claimed in claim 1 wherein the spring is a polymer.

11. The inflow control device as claimed in claim 1 wherein the spring is metallic.

12. A method for controlling fluid loss for a period of time comprising:
plugging an inflow control device as claimed in claim 1 ;
exposing the barrier to a fluid that dissolves or disintegrates the barrier; and
dissolving or disintegrating the barrier.

13. The method as claimed in claim 11 further comprising producing fluid through the device upon a pressure differential across the closure member exceeding a spring force of the spring.
