A production testing update has been provided by Golden State Resources (ASX: GDN) for Paradox Basin #2 well in Grand County, Utah.
Testing of the Chimney Rock Formation has been completed. The Chimney Rock Formation was perforated and acidized before a series of flow periods. The formation was found to be a good reservoir and was not fracture stimulated due to high formation permeability.
Gas was not recovered during a series of flow tests which recovered all of the injected fluids before a change in salinity indicated the well was flowing formation waters.
Gas was not produced during the initial testing so additional perforations were placed over the interval 12,284’ to 12,299’which had displayed a strong gas show while drilling.
Further flow periods did not recover any hydrocarbons.
The Chimney Rock Formation is being abandoned after completion of acid stimulation and testing. The Chimney Rock Formation was not an objective in Paradox Basin #2.
However, Chimney Rock is considered to have a stratigraphic closure and pinch-out up dip towards the Paradox Basin #1 well.
Next testing will be the Ismay Formation.
Preparations are now underway for testing the Ismay Formation which has proven production in Paradox Basin #1 and is considered the principle zone of interest in commercialising the Golden Eagle gas field.
The Ismay Formation is the main productive interval in the Paradox Basin accounting for 25.9% of all produced gas and 85% of produced oil. Paradox Basin #2 has encountered the Ismay Formations 283’ (86m) lower in the structure than the confirmed productive zone in Paradox Basin #1.
The Ismay Formation will be perforated from 10,344’ to 10,383’ (3153-3165m) prior to a series of flow and injection tests. It is planned to then conduct a hybrid frac which is modelled to penetrate approximately 2000’ (600m) into the formation.
Operations are currently underway and are expected to take about 12 days.
Of interest, GDN is currently preparing to obtain a completion rig to work-over Paradox Basin #1 in order to rerun the tubing and conduct an extended flow test and prepare the well for production.
