摘要： A drill bore protection device and method for protecting a drill bore are provided. The drill bore protection device includes an elongated member. The elongated member is defined by a front end and a rear end. A first sleeve is placed on the elongated member next to the front end of the elongated member. Additionally, a second sleeve is placed on the elongated member next to the rear end of the elongated member. The first sleeve and the second sleeve each have an open end and a closed end. The closed ends of the first sleeve and the second sleeve face the front end of the elongated member, while the open ends of the first sleeve and the second sleeve face the rear end of the elongated member. The first sleeve defines a first interior cavity. A liner is disposed in the first interior cavity of the first sleeve.

摘要： A layer of permeable material is positioned on an area of lost circulation lithology in a wellbore. An example of the permeable material includes a planar member with perforations that is rolled into and retained in an annular configuration. The permeable material is lowered into the wellbore adjacent the area of lost circulation and allowed to unroll and expand radially outward against walls of the wellbore. The wellbore wall along the area of lost circulation lithology can be reamed out so the layer of permeable material is out of the way of a drill bit. Applying a bridging agent on the interface where the permeable material contacts the wellbore wall forms a flow barrier.
