Abstract

A fracing and production configuration including a tubular having a plurality of openings. The openings having a beaded matrix therein, a valve sub in operable communication with the tubular and an underminable plugging material plugging each of the beaded matrixes. A method for fracing and producing from a wellbore in a formation.

Claims

1. A fracing and production configuration comprising:

a tubular having a plurality of openings, the openings having a beaded matrix therein;

a valve sub in operable communication with the tubular;

an underminable plugging material, plugging each of the beaded matrixes.

2. The configuration as claimed in claim 1 wherein the valve sub is a sliding sleeve.

3. The configuration as claimed in claim 1 wherein the beaded matrixes are disposed within individual housings.

4. The configuration as claimed in claim 1 wherein the plugging material has sufficient structural integrity to withstand fracing pressures.

5. The configuration as claimed in claim 1 wherein the plugging material is underminable by acid disintegration.

6. The configuration as claimed in claim 1 wherein the plugging material is underminable by downhole exposure for a selected time.

7. A method for fracing and producing from a wellbore in a formation comprising:

running a configuration as claimed in claim 1 to depth in a wellbore;

actuating a valve sub;

pumping a fracing fluid into the wellbore and through the valve sub into the formation;

undermining the underminable plugging material; and

producing a target fluid through the beaded matrixes into the configuration.

8. The method as claimed in claim 7 wherein the actuating is by remote actuation.

9. The method as claimed in claim 7 wherein the actuating is by mechanical intervention.

10. The method as claimed in claim 7 wherein the actuating includes opening of the valve sub.

11. The method as claimed in claim 7 wherein the actuating includes closing of the valve sub.

12. The method as claimed in claim 7 wherein the undermining includes applying acid to the underminable plugging material.

13. The method as claimed in claim 7 wherein the undermining includes exposing the underminable plugging material to wellbore conditions for a selected period of time.
