Norwest Energy completed a 14-day well test and production logging program at the Arrowsmith-2 well in the Perth basin in Western Australia.
The company said the analysis and interpretation of the dataset from this final test work to evaluate the contribution of gas and fluids from each of the perforated targets intervals is in progress.
During the well test and production logging program, gas production was identified by the production logging tool (PLT) at all zones in the commingled environment with collected data indicating percentage contributions from each of the individual target intervals.
The next phase, which has already started, is analyzing and interpreting the results from the PLT program to ascertain the gas flow rates from each of the target intervals. The analysis is expected to take several weeks to finish; the results will be crucial in determining the optimal zone and target interval in planning to drill the first horizontal well, Arrowsmith-3.
The PLT tested four intervals – the High Cliff sandstone, the Irwin River Coals Measures, and the two zones of the Carynginia Formation.
