The final six-inch diameter section of the well is now drilling through the deeper K sands targets to the proposed total depth of 4,115 metres. If further gas sands are encountered, further casing will be run prior to an extensive testing program.
BG Webb-1 is specifically targeting up to 19 billion cubic feet of recoverable gas in the combined J and K sands. It should reach the new proposed total depth of 4,115 metres later this week.
Victoria Petroleum managing director John Kopcheff said the additional gas shows could add more gas reserves to those already drilled and seen on the wire line logs.
“We are very pleased that the drilling results and wire line logs from the BG Webb-1 well to date are meeting our pre-drill recoverable gas reserve estimates with between 75 to 100 billion cubic feet of deeper gas potential proved by this well so far,” Kopcheff said.
“Additional reserves may be anticipated should the K sands now being drilled be gas bearing. With the deepening of the well by 305 metres, we are looking forward to drilling another 425 metres through the K sand target zone to possibly prove more K sand gas reserves in this well now that we are seeing further gas shows.”
There was also a strong chance of a further potential 100 billion cubic feet of gas being present on the northern flank of the field, according to Kopcheff.
“Our expectation of proving 160 BCF of deeper recoverable gas reserves in the western half of the Flour Bluff gas field underlying the current shallow gas reserves of 92.5 BCF is well on track and may even be exceeded with the continuing drilling in this well and subsequent development drilling,” he said.
“We are very excited about the impact a successful BG Webb-1 well will make first up on the Flour Bluff Gas Development Project. 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.”
