US oil and gas company Golden State Resources (ASX: GDN) has encountered further gas shows at the Paradox Basin # 3 production well, from 11,367’ to 11,378 feet in the Pennsylvanian Ismay Formation.
Gas levels reached 270 units in a mixed clastic formation. The show was associated with a two fold increase in rates of penetration. Porosity was described as "intergranular".
The Paradox Basin #3 is currently at 11,565’ and drilling ahead and likely to reach 12,000 feet tomorrow. Drilling did not recommence until Sunday due the requirement to run a milling tool and junk basket, following the failure of a stabiliser during the reaming run.
All the stabilisers have since been replaced. The hole is currently in good condition and operations are proceeding.
Gas levels reached 1453 units over zone 3 during reaming, and 1823 units whist running a junk basket, the well continues to show high operational gas levels. The gas influxes are considered by the company to originate primarily from Show 3 which occurred over a 42’ interval during a drilling break in limestone from 11,012’ to 11,054’.
Logging is expected to commence on Wednesday and take one day.
Logs will be sent to RPS Energy for preliminary petrophysical evaluation to confirm the presence of gas. Paradox Basin #3 will be then completed with 5” casing.
Data from the well will be more comprehensively evaluated by RPS Energy to assist in the design of the completion, testing and stimulation programme.
