Abstract

An apparatus () and method for treating an interval of a wellbore comprises an outer tubular () disposed within the wellbore. A sand control screen () is disposed within the outer tubular (). A treatment fluid passageway () is formed between the sand control screen () and outer tubular (). In addition, a production pathway () is formed between the sand control screen () and outer tubular (). When the apparatus () is in an operable position, the region between the outer tubular () and the wellbore serves as a primary path for delivery of a treatment fluid, the production pathway () serves as a secondary path for delivery of the treatment fluid if the primary path becomes blocked and the treatment fluid passageway () serves as a tertiary path for delivery of the treatment fluid if the primary and secondary paths become blocked.
