Abstract
Methods and systems for isolating a loss circulation zone of a subterranean formation includes lowering a drill string having a tubular member from a surface into a subterranean well and securing a packer assembly to the tubular member, the packer assembly having an inflatable packer unit and a protective sleeve. The protective sleeve is in an extended position and circumscribes the inflatable packer unit and the inflatable packer unit is in a deflated condition. A stabilizer body is secured to the tubular member downhole of the packer assembly. The stabilizer body is shaped to centralize the packer assembly and direct debris traveling uphole in a direction radially outward of the packer assembly. The protective sleeve is moved from the extended position to a retracted position. The inflatable packer unit is inflated to an inflated condition, forming a seal with an inner diameter surface of the subterranean uphole of the loss circulation zone.
