Paper Number: SPE-205397-PA
Published: 10 November 2021
...Mohamed Elsafih; Mashhad Fahes Summary It is common to inject acidic stimulation fluids into oil-bearing carbonate formations to enhance well productivity. This process of matrix acidizing is designed to maximize the propagation of wormholes into the formation by optimizing the injection parameters...

... mechanisms from the simulation. The model was then incorporated into an integrated carbonate-acidizing simulator. Particulate diversion is not generally used in carbonate acidizing because of the formation of wormholes and the potential difficulty in removing particles from the induced perforation/wormhole...
