Acidizing/stimulation
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.
The creation of SPE’s Acid Stimulation Technical Section shines a light on the technique that improves injectivity and productivity. JPT talked with the chair of the new section about the importance of the technical area.
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.

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. -
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.

Field examples of operators using chemical restimulation to boost production in aging unconventional wells as an alternative to acid treatments.
-
This paper highlights an approach of using active hydrogen to stimulate hard-to-recover formations from candidate-well selection through pilot execution and evaluation.
-
The objective of this study is to use expired medications as green corrosion inhibitors that can be used during stimulation treatments. Because the medications are expired and not fit for human consumption, the cost is inherently low.

This paper presents a case study of a North African oil field producing from two Ordovician sands with differing permeabilities where significant benefit was achieved by fracture stimulating one or both intervals in two wells.
-
This paper describes the stimulation of a horizontal water-injection well with a limited-entry-liner completion in an onshore carbonate reservoir using a large volume of viscoelastic diverter-acid fluid system ahead of the main acid stage.

This paper details a successful pilot to improve long-term well performance using acid stimulation aided by a tailored metal oxide nanoparticle-based fluid in the Wolfcamp A formation.
