The newly discovered lower multiple Frio K series pay zones in this section of the well are the deepest ever drilled in the Flour Bluff Gas Field, according to the Flour Bluff partners, which include Australian firms Sun Resources, Victoria Petroleum Limited and Aurora Oil & Gas.
Successful flow tests on these new pay zones could add additional significant reserves to the 104 billion cubic feet of recoverable gas already estimated by the operator to be already present behind casing above 3,255 metres in the western portion of the Flour Bluff Gas Field, joint venture partner Victoria Petroleum said.
“We are very excited about the impact a successful BG Webb-1 well has made first up on the Flour Bluff Gas Development Project,” said Victoria Petroleum managing director John Kopcheff.
“Success here will prove the concept that major gas reserves of up to 227 billion cubic feet are sitting under this western part of the currently producing shallow gas field. Total potential gas reserves of up to 300 billion cubic feet of gas in all categories are considered possible for the whole field based on the operator’s mapping.
The joint venture has accepted the operator’s recommendation to set five-inch liner from 3,740 metres back into the seven-inch casing at 3,255 metres so that these four potential gas pay zones can be flow tested, fracture stimulated and produced if warranted, Victoria Petroleum said.
After running and cementing the liner, the drilling rig is expected to be released and immediately moved to the second well in the Flour Bluff drilling program, East Flour Bluff D-24.
At BG Webb-1, a well service rig is anticipated within 28 days to move in for well completion and fracture stimulation operations which may run for a further 30-40 days. A decision will then be made on which gas pay to test and produce first.
The joint venture has approved the construction of a pipeline to connect the BG Webb-1 well to the joint venture’s gas gathering system for the Flour Bluff Field. Permitting for the pipeline is in progress.
