Abstract

A sand screen assembly including a base pipe, a filtration subassembly disposed about the base pipe, the filtration assembly being removable and replaceable on the base pipe as a subassembly, a hollow defined between the filtration subassembly and the base pipe, a removable and replaceable end cap securable to the base pipe with a fastener and configured to retain the filtration subassembly on the base pipe. A method for installing a tracer material in a sand screen assembly. A downhole system including a base pipe, a filtration subassembly disposed about the base pipe, the filtration assembly being removable and replaceable on the base pipe as a subassembly, a hollow defined between the filtration subassembly and the base pipe, a removable and replaceable end cap securable to the base pipe with a fastener and configured to retain the filtration subassembly on the base pipe.

First claim

What is claimed is:

1. A sand screen assembly comprising:
a base pipe;
a filtration subassembly disposed about the base pipe, the filtration assembly being removable and replaceable on the base pipe as a subassembly and including tall ribs and short ribs extending radially inwardly from a filtration material interspersed with one another, the tall ribs being secured to the filtration material and slide on the base pipe;
a hollow defined radially between the filtration subassembly, the tall and short ribs and the base pipe, the hollow dimensioned and positioned to receive a block of tracer material;
a removable and replaceable end cap securable to the base pipe with a fastener and configured to retain the filtration subassembly on the base pipe.

2. The sand screen assembly as claimed in claim 1 further comprising a tracer material block disposed in the hollow.

3. The sand screen assembly as claimed in claim 2 wherein the tracer material block is adhered to the base pipe.

4. The sand screen assembly as claimed in claim 1 further comprising a plurality of tracer materials in a plurality of tracer material blocks in a plurality of hollows.

5. The sand screen assembly as claimed in claim 4 wherein the plurality of tracer materials are the same material.

6. The sand screen assembly as claimed in claim 4 wherein the plurality of tracer materials are of different materials.

7. The sand screen assembly as claimed in claim 1 wherein the sand screen assembly further includes rings disposed between the filtration subassembly and the base pipe to provide radial support to the filtration subassembly.

8. The sand screen assembly as claimed in claim 7 wherein the hollow is defined between adjacent rings.

9. The sand screen assembly as claimed in claim 7 wherein the rings are secured to the base pipe.

10. The sand screen assembly as claimed in claim 1 further comprising one or more of a valve and an inflow control device in fluid communication with the filtration subassembly.

11. A method for installing a tracer material in a sand screen assembly at point of use comprising:
unsecuring an end cap of a sand screen assembly as claimed in claim 1 ;
removing the end cap from the base pipe;
removing, by sliding, the filtration subassembly of the sand screen assembly from the base pipe;
disposing a tracer material block on the base pipe;
replacing the filtration subassembly on the base pipe over the tracer material block; and
replacing and resecuring the end cap.

12. The method as claimed in claim 11 wherein the disposing the tracer material block further includes adhering the tracer material block to the base pipe.

13. The method as claimed in claim 11 wherein the disposing is disposing multiple tracer material blocks in hollows of the sand screen assembly.

14. A sand screen assembly comprising:
a base pipe;
a filtration subassembly disposed about the base pipe, the filtration assembly being removable and replaceable on the base pipe as a subassembly and including tall ribs and short ribs extending radially inwardly from a filtration material interspersed with one another, the tall ribs being slidable on the filtration material and secured to the base pipe;
a hollow defined radially between the filtration subassembly, the tall and short ribs and the base pipe, the hollow dimensioned and positioned to receive a block of tracer material;

a removable and replaceable end cap securable to the base pipe with a fastener and configured to retain the filtration subassembly on the base pipe.

15. A downhole system including:
a base pipe;
a filtration subassembly disposed about the base pipe, the filtration assembly being removable and replaceable on the base pipe as a subassembly and including tall ribs and short ribs extending radially inwardly from a filtration material interspersed with one another, the tall ribs being secured to the filtration material and slide on the base pipe;
a hollow defined radially between the filtration subassembly, the tall and short ribs and the base pipe, the hollow dimensioned and positioned to receive a block of tracer material;
a removable and replaceable end cap securable to the base pipe with a fastener and configured to retain the filtration subassembly on the base pipe.

16. The system as claimed in claim 15 further comprising one or more of a valve and an inflow control device in fluid communication with the filtration subassembly.
