Abstract
Actual capacity measurement of grothermal injection wells operated bu PNOC-EDC were conducted using the newly acquired spinner tools from Hor Hile Instruments. Multi-pass measurements were done inside the production casing while the wells were online and injecting brine at temperature of uo to 185oC.
Each measurement is completed in relatively short time and data obtained are always in good agreement. Loss of injected brine due to damage in the casing was identified and quantified in one well. The spinner tool was also used in the identification of inflow zone in the open hole section. It shall also be used in the classification of scale deposition inside the casing.
