Acidizing/stimulation
The Acid Stimulation Technical Section aims to provide a global home for engineers, scientists, researchers, and practitioners working on acid stimulation in carbonate and sandstone reservoirs.
This paper presents a case study of a tool-free fishbone fracture stimulation technology using sand jetting and acidizing in openhole wells, providing a technical solution for low-permeability and complex-lithology carbonate reservoirs in the Middle East.
This paper presents a case study of oriented tubing-conveyed perforation followed by an acidizing operation to overcome technical challenges posed by a depleted reservoir targeted for a carbon capture, utilization, and storage project.

Carbon dioxide (CO2) with 30% foam quality (FQ) has been introduced for the first time during acid fracturing treatments in a tight, sour, high-pressure/high-temperature carbonate gas reservoir in Saudi Arabia. -
This work introduces sodium gluconate as an efficient and environmentally friendly iron-chelating agent.
-
The technical contributions highlighted this year focus on matrix stimulation of carbonate and unconventional reservoirs.
-
Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs.
-
Mechanical-diversion techniques can ensure acid injection into the various intervals of naturally fractured reservoirs.
-
An operator developing tight carbonate reservoirs found that conventional acid stimulation with 15% hydrochloric acid (HCl) in horizontal wells did not provide expected results.
-
At the SPE Hydraulic Fracturing Technology Conference, one of the most innovative ideas discussed was a liquid proppant designed to turn into strong spherical balls to keep a fracture open.
-
The lower tertiary formation found in the pre-salt layers of the Gulf of Mexico has become a proving ground for extending what is possible when completing multistage fracturing in ultradeepwater wells.
-
This work describes the positive results experienced when a self-diverting acid system based on a viscoelastic-surfactant (VES) technology was introduced for carbonate-reservoir stimulation offshore Brazil.
-
This paper describes a matrix-acidizing campaign executed successfully in the Gulf of Cambay on the west coast of India.
