Woodside has developed big bore gas wells that allow for much higher production rates compared to standard wells. Their big bore wells can produce up to 400 million standard cubic feet per day through 9 5/8 inch tubing, which is four times more than standard wells. While big bore wells provide significant economic benefits with lower costs, fewer platforms and wells required, they also present engineering challenges to design and operate reliably due to higher sand erosion risks. Woodside has successfully addressed these challenges through innovations like expandable sand screens to protect well integrity and enable production from fewer ultra-high rate big bore wells.
