ABSTRACT:
In the area of oilfield wellhead equipment, and specifically the wellhead valve known as the master valve on the wellhead array, there is often the necessity to remove this valve for repairs or for its replacement by some other piece of equipment such as a blow out preventer, this service being done while the well is under pressure from the fluids or gases normally being produced or for any other reason.
A novel packer is described which can be put into place in a section of the well tubing or casing close to the master valve using a novel tool which is also described. This packer will isolate the master valve from the well fluids and pressure, allow it to be taken off and replaced, or other equipment to be installed in its place, and also allow the master valve, its connections, or other equipment thus put on the well, to be pressure tested prior to removing the packer from the well tubing or casing and restoring the gas or fluid pressure to the wellhead array.
