Last update September 14th:
Operations commenced for acidisation and testing following rig up on the 9th of
September.
The Pa IV gas reservoir interval was acidised utilising coiled tubing for pumping
acid to the bottom of the well and then the acid and brine in the well was circulated
to surface utilising nitrogen to enable lifting liquids from the well.
Gas flow was observed after approximately 12 hours, preceded by liquids consisting
of brine, acidisation fluids, minor amounts of reservoir fluid and a sludge likely
consisting of reservoir fines and chemical precipitation materials formed by the
acidisation process.
The well will be shut in and monitored to determine if the reservoir will clean up
further over time.
Well performance to date is below expectation given the excellent porosity observed
from logs, gas shows during drilling, cutting descriptions from IMIC-1 and flow rates
achieved from the same reservoir from a nearby historic well.
Plenty of time has passed for dat gathering so hence my view that an update on the 2nd drill is due. However the performance of IMIC-1 may have changed drilling tactics and I know there was discussion her of them drilling 'underbalanced' in the future to avoid blocking the well. Seems they should flow them immediately too and not shut them in!
