Abstract

A method of treating and producing formation fluids includes introducing a first drop ball into a string of tubulars, pumping the first drop ball to a first ball seat, applying pressure to the first drop ball to shift a first sleeve exposing an outlet port, introducing a second drop ball into the string of tubulars, pumping the second drop ball to a second ball seat, applying pressure to the second drop ball to shift a second sleeve closing the outlet port and opening an inlet port, and introducing a fluid through at least one of a first injection port directly onto the first drop ball and a second injection port directly onto the second drop ball. The first injection port is arranged upwardly of the first sleeve and the second injection port is arranged upwardly of the second sleeve.

First claim

What is claimed is:

1. A method of treating and producing formation fluids from a formation comprising:
introducing a first drop ball into a string of tubulars;
pumping the first drop ball to a first ball seat;
applying pressure to the first drop ball to shift a first sleeve exposing an outlet port;
introducing a second drop ball into the string of tubulars;
pumping the second drop ball to a second ball seat;
applying pressure to the second drop ball to shift a second sleeve closing the outlet port and opening an inlet port; and
introducing a fluid through at least one of a first injection port directly onto the first drop ball and a second injection port directly onto the second drop ball, the first injection port being arranged upwardly of the first sleeve and fluidically connected to the first ball seat and the second injection port being arranged upwardly of the second sleeve and fluidically connected to the second ball seat, the first and second injection ports being fluidically connectable to a fluid conduit arranged externally of the string of tubulars.

2. The method of claim 1 , further comprising: selectively controlling the first and second injection ports.

3. The method of claim 1 , wherein introducing the fluid includes introducing a fluid selected to accelerated degradation of the at least one of the first and second drop balls.

4. The method of claim 1 , further comprising: treating the formation through the outlet port and producing formation fluids through the inlet port.

5. The method of claim 1 , wherein opening the inlet port includes exposing an inflow control device to a fluid flow.

6. The method of claim 1 , further comprising: passing a flow of fluid through a screen assembly into the inlet port.

7. The method of claim 1 , wherein introducing the fluid into the first injection port includes opening a selectively controllable valve.
