摘要: A new wellbore apparatus has been invented which, in certain aspects, has anchor apparatus (42) for anchoring the wellbore apparatus in a bore, the anchor apparatus actuated by fluid under pressure supplied thereto, and sealing apparatus (40) selectively inflatable to close off the bore to fluid flow there through, and temperature compensating apparatus (48) for maintaining a desired fluid pressure in the sealing apparatus to prevent it from bursting or deflating.
