Acidizing/stimulation

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.
