Abstract: A retrievable inflatable plug system features distinct seal and anchor elements where the seal element features overlapping ribs preferably metallic and preferably overlapping. The ribs extend the substantial length of the packer and are disposed under the annularly shaped sealing element. The anchor features exposed continuous ribs extending from opposed ends with one or more stiffener rings disposed on the exposed ribs. The elements can be inflated separately or together and include valving systems to allow deflation for selective removal of the plug to put a well back into service.
