... at the surface. The induction times predicted from ScaleSoftPitzer are compared with the experimental results. A quarter-inch tubing dynamic loop was built to run the deposition experiments (Figure 1) . The apparatus consisted of two Pharmacia P-500 for brine injection. The brines were mixed in a PTFE...

... and these are rather unreliable, since few experimental results have been published. In essence, this quantity (the H 2 S retardation factor) is more of a "matching parameter" rather than being truly predictive. Candidate mechanisms for sulfide scavenging by iron-bearing minerals have been experimentally identified...

To observe if the method is applicable to relatively higher temperatures, we ran experiments at 75 °C with SI 0.45 [ Figure 8 ] and 90 °C with SI 0.2 [data not shown]. In both of the cases, predicted and experimental values were observed similar to each...

The skin temperature in pure water was significantly lower than in MEG solutions at the same flow rate. This is mainly attributed to different viscosity. In the experiments, the flow rate on the MEG solution...
