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.
