摘要： A system for subsurface measurements in a wellbore, with a first tool including a first plurality of pads to be positioned against a surface of the wellbore, each of the pads having a first plurality of electrodes disposed thereon to emit and receive electric alternating current between the electrodes and a second plurality of electrodes disposed thereon between the first plurality of electrodes to measure an electromagnetic parameter. Also including a second tool including a second plurality of pads to be positioned against a surface of the wellbore, each of the pads having a first plurality of electrodes disposed thereon to emit and receive electric alternating current between the electrodes and a second plurality of electrodes disposed thereon between the first plurality of electrodes to measure an electromagnetic parameter. The second tool is longitudinally offset from the first tool and the second plurality of pads of the second tool are rotationally offset relative to the first plurality of pads of the first tool.

摘要： An apparatus for generating a seismic signal in a wellbore includes an elongated housing configured to be disposed in the wellbore; a piston slidably disposed in an internal bore in the elongated housing; a strike plate fixed on the elongated housing proximate one end of the internal bore; and an energizing mechanism configured to move the piston to hit the strike plate. A downhole system for seismic survey of a formation penetrated by a wellbore includes at least one seismic receiver; a seismic source; and at least one inflatable packer configured to separate the seismic source and the at least one seismic receiver in different compartments in the wellbore when inflated.
