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.

This paper reviews existing literature, the operator’s records, service-company data, and simulation studies to assess the risk of using seawater in carbonate acidizing. -
The paper describes a project in which extremely challenging stimulations were performed in a fractured tight carbonate in a complex strike/slip stress faulting regime with high tectonic stresses.

The works highlighted in this year’s Acidizing feature demonstrate novel, diverse innovations in sustainability, enhanced productivity, and logistical efficiency by authors of SPE conference papers.
-
This paper reviews fracturing-program design, completion technology, real-time data collection, data integration, and lessons learned for the Pikka development on the North Slope of Alaska.
-
A Chinese operator in the Sichuan Basin used high‑frequency pressure monitoring to evaluate frac performance in unconventional wells.
-
This study explores enhancing gas production through a novel combination of prestimulation using a coiled tubing unit and high-rate matrix acidizing.
-
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.
-
This paper extends an integrated two-scale continuum model that contemplates mass, momentum, and energy changes to study the acid-stimulation process in complex carbonate acid-stimulation systems with the development of fracture and vug networks.
-
The authors of this paper write that autonomous outflow-control devices can positively affect matrix acidizing by providing the best possible conformance.
-
In this work, microseismic observations are integrated with strain and other observations to investigate the microseismic response in relation to the underlying hydraulic fracture geometry for different rock types.
