ABSTRACT:
The invention is an oil well capping device that may be forced into an oil well casing through which oil and/or gas under high pressure is emanating, to temporarily completely obstruct the flow of such oil until repairs to the well head structure have been completed before the device is removed, and includes a well sealing arrangement utilizing an axial compression system that causes elastomeric material elements mounted on an elongated shaft to radially expand and temporarily and safely seal off the well casing.
