The challenge of matrix acidization remains the fair distribution of the acid treatment along the wellbore. Acid prefers the less-resistant spots along the wellbore characterized by high-permeability streaks or fractures. To counter this challenge, a completion consisting of autonomous outflow-control devices (AOCD) was implemented. In the complete paper, a novel approach is developed through modeling to demonstrate that autonomous flow-control devices can provide substantial value in stimulation operations.
AOCD Technology
This paper is specific to the use of AOCD in acid-stimulation operations, presenting it as an option for injection wells irrespective of the planned operation.
