Summary:
Over the past 3 years, an operator in Malaysia has developed several large-bore gas wells with horizontal trajectories. The
completion team was faced with several challenges in designing the completion of these wells, particularly in the area of
deploying a plugging device to test the completion string and to set the production packer. Traditionally, two conventional
plugging methods have been used ― slickline-deployed plugs or ball-activated pump-out plugs. Due to the deviated
trajectories and associated intervention risks, both methods were deemed unfeasible. A coiled-tubing intervention could have
been considered, but this method would have added significant cost to the completions. To actualize these wells, therefore, an
operator needed to find an alternative method that would provide a low-risk, cost-effective tubing-testing and packer-setting
device.
