... Abstract Scaling problems were identified in a typical tight carbonate gas reservoir. Selecting an effective iron carbonate scale inhibitor in low-permeability (≤ 1 mD), high-temperature, low-pressure, and low water-cut gas wells of this reservoir type can be challenging. The scale treatment...
