Abstract: A method for performing a seismic investigation during subterranean drilling operations includes connecting a bottom hole assembly to a drill string. The bottom hole assembly includes a drill bit and a vibration damper. The drill string is lowered into a borehole and rotated to drill the borehole to a greater length with the drill bit. An actual vibration generated by the bottom hole assembly is measured with a control system and the actual vibration is compared to a target seismic vibration range. When the actual vibration is outside of the target seismic vibration range, the dampening coefficient of the vibration damper is changed.

Abstract: 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. A bridging agent can be applied on the interface where the permeable material contacts the wellbore wall.
