Circulating wells

Consider reformulating the catalyst—custom formulations are available. Increasing rare-earth content can reduce the wet gas rate. Catalyst is usually selected for properties other than its ability to flow. However, if it does not flow, it is not going to work well. Catalyst physical properties should be compared with those of catalysts that have circulated well. Evaluate the economics of using metal passivation additives and other catalyst enhancing additives.

Groundwater circulation wells (German abbreviation GZB) are constructed with two screened sections one placed at the bottom of the aquifer, and one approximately at the water table. In a GZB circulation ceU, water is withdrawn through one screened section and reinjected through...
