Abstract

A screen connection area assembly configured to mount between adjacent sand screens of a gravel pack string including a body attachable to a screen connection area between two adjacent sand screens of the gravel pack string, the body configured to displace fluid and present a radial dimension between about 75% and 100% of a radial dimension of the adjacent sand screens. A method for packing a gravel pack string including disposing an assembly as in any prior embodiment on a screen connection area between adjacent sand screens of the string, running the string into a borehole, supplying a slurry to the borehole proximate the sand screens, packing the sand screens and the screen connection area between adjacent sand screens without altering a flow regime of the slurry.

First claim

What is claimed is:

1. A screen connection area assembly configured to mount between adjacent sand screens of a gravel pack string comprising:
a body attachable to a screen connection area between two adjacent sand screens of the gravel pack string, the body configured to displace fluid and present a radial dimension between about 75% and 100% of a radial dimension of the adjacent sand screens, the body comprising:
a tube carrier having a radially inward surface configured to nest with a base pipe and a radially outer surface having a hold down feature configured to accept a tube;
a backing having a radially inward surface configured to nest with the same basepipe; and
a pair of flaps, one articulated to each of two sides of the backing and configured to fixedly interengage the tube carrier, the tube carrier, backing and pair of flaps together creating the body configured to wrap the base pipe.

2. The assembly as claimed in claim 1 wherein the body further presents a circumferential continuity of the radial dimension for greater than about 324 degrees.

3. The assembly as claimed in claim 1 wherein the body radial dimension is between about 85% and 100% of the radial dimension of the adjacent sand screens.

4. The assembly as claimed in claim 1 wherein the body radial dimension is between about 95% and 100% of the radial dimension of the adjacent sand screens.

5. The assembly as claimed in claim 1 wherein the assembly comprises a fluid impermeable material.

6. The assembly as claimed in claim 5 wherein the assembly is hollow.

7. The assembly as claimed in claim 1 wherein the body includes stand offs creating a flow gap between the body and a base pipe when in use.

8. The assembly as claimed in claim 1 wherein the body includes leak off grooves.

9. The assembly as claimed in claim 8 wherein the leak off grooves are helically arranged.

10. The assembly as claimed in claim 1 wherein the articulated flap is articulated at a hinge point that allows both rotation and translation.

11. The assembly as claimed in claim 1 wherein the articulated flap includes a latching feature.

12. The assembly as claimed in claim 11 wherein the articulated flap includes a securement.

13. The assembly as claimed in claim 12 wherein the securement is a threaded fastener.

14. The assembly as claimed in claim 1 wherein the articulated flap includes a stop configured and positioned to when closed prevent disengagement of a slide connector of a jumper tube.

15. A gravel packed string comprising:
two or more sand screen joints having sand screens thereon;
an assembly as claimed in claim 1 disposed between the sand screens of the two or more sand screen joints.

16. A method for packing a gravel pack string comprising:
disposing an assembly as claimed in claim 1 on a screen connection area between adjacent sand screens of the string;
running the string into a borehole;
supplying a slurry to the borehole proximate the sand screens;
packing the sand screens and the screen connection area between adjacent sand screens without altering a flow regime of the slurry.

17. The method as claimed in claim 16 further including displacing slurry with the assembly.
