Abstract
An inflatable borehole plug comprising an inflatable fluid tight bag with a storage container containing an inflation fluid in a compressed state located within the fluid tight bag. The storage container has a first actuator and a second actuator located at opposite ends thereof to initiate release of inflation fluid and hence effect expansion of the fluid tight bag. Choice of the vertical orientation of the first and second actuators and of which or both are activated provides differing rates of release of the inflation fluid and corresponding different rates of inflation of the fluid tight bag.
