Key words: geothermal temperature, HPHT wells, scale inhibitors, calcium tolerance, calcite inhibition © 2024 Association for Materials Protection and Performance (AMPP...

... 3 Common Extraction Methods. Extraction efficiency is one of the largest differentiators for each testing method. Extraction efficiency is defined as the quantity of salt retrieved from the surface as a percentage of the total amount originally on the surface. Some studies found that the efficiency...

... and Langmuir Isotherm fit for (a) BAC-C12 and (b) BAC-C16 in a CO2-saturated 1 wt.% NaCl brine at pH 4, 50°C and 1000 rpm Figure 6(a) shows that the corrosion inhibition performance of BAC-C12 is very poor, even at a concentration of 5000 µM with coverage only reaching 0.16 (16% efficiency). Conversely, BAC...

Lab results showed MTDF-9339 passed all mandatory tests and will be conducted for field trials...

... was investigated. The experimental results show the aged DETPMP presented similar inhibition efficiency for CaCO 3 but less efficiency for CaSO 4 formation prevention compared to the non-aged DETPMP at 105°C in high salinity waters. The chemical characterization of DETPMP using IR and NMR demonstrated...
