ABSTRACT:
A method and apparatus is provided for extending a pressurization time interval. The pressurization-extending device includes a number of components which cooperate together. The pressurization-extending device is coupled between a source of pressurized fluid, such as a pump, and a fluid-actuated wellbore tool, such as an inflatable packer or inflatable bridge plug. The components include an input for receiving pressurized fluid from the source of pressurized fluid, and an output for directing pressurized fluid to the fluid-actuated wellbore tool to supply an actuating force to the fluid-actuated wellbore tool. The pressurization-extending device further includes a timer device, which is responsive to the actuating force of the pressurized fluid, for automatically maintaining the actuating force of the pressurized fluid within the fluid-actuated wellbore tool at a preselected force level for a preselected time interval.
