Norwest Energy reported that operations on the Arrowmsith-2 well recommence today.
Arrowsmith-2 well has been temporarily shut-in whilst awaiting delivery to site of the necessary parts and equipment to install a smaller diameter tubing completion within the well.
The procedure to install the completion is to drill out the remaining bridge plugs and immediately isolate the High Cliff Sandstone (HCSS) interval from the other zones with a completion packer. This is expected to take approximately three weeks to complete. 2 3/8” tubing will then be run from surface to the installed packer, and the HCSS interval flowed back in isolation for a period of 2-3 weeks.
Following this extended testing period on the HCSS, the two shallower intervals, the Irwin River Coal Measures (IRCM) and the Carynginia Formation will be flowed back until sufficient frac fluids have been removed in order to establish gas rates for each of these intervals.
The entire program is expected to take 3-4 months to complete.
