Acidizing/stimulation
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 discusses a novel approach to abrasive perforating, including the first-ever use of an acid-soluble abrasive material and ending with CT-jetting-assisted nitrified stimulation. -
This paper describes the testing of a novel concept based on resistivity measurements to monitor acid-stimulation operations.
-
This paper summarizes a wide variety of sandstone-acid-stimulation case histories, highlighting aspects such as mechanical conditions and operational practices.
-
While there is increased scrutiny from regulatory and community stakeholders on the chemicals used in operations, complex and technically challenging reservoirs must be developed to replace reserves. Matrix stimulation remains a critical technology for delivering barrels at minimum cost.
-
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 paper presents experimental and field-case studies with a sandstone-acidizing treatment designed to retard the hydrofluoric acid reaction rate and enable single-stage treatment.
-
This paper studied three residual-free fluid systems for acid treatments and fracturing in order to develop no-damage or reduced-damage and highly effective stimulation techniques for long-interval wells.
-
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.
