    Abstract: This disclosure describes a device and method of sealing perforations on a well casing inside a subterranean well. The device comprises a generally cylindrical sleeve having a open top and a closed bottom; a heater located inside the sleeve, the heater comprising a thermite mixture; an ignition mechanism that ignites the thermite mixture upon actuation; and a string connected to the heater ignition and detachably engages the sleeve. The method comprises lowering a body of meltable plugging material into the well casing near the perforations; lowering the plugging device into the well casing immediately on top of the body of meltable plugging material; melting the meltable plugging material by igniting the thermite thereby transferring heat to the body of meltable plugging material; forcing the molten plugging material into the perforations by pushing the plugging tool further downhole; cooling the plugging tool and the plugging material until the plugging material solidifies; disengaging the tubing string from the sleeve and retrieving the tubing string with the heater; and removing the sleeve and bismuth remaining in the well casing, but not in the perforations.

    CPC classification number: G01V1/3826 ,  G01V1/20

    Abstract: The invention relates to an arrangement for seismic acquisition the spacing between each adjacent pairs of receiver and sources lines is not all the same. Some receiver and/or source lines and/or receiver and/or source spacings are larger and some are smaller to provide a higher quality wavefield reconstruction when covering a larger total area or for a similar total area of seismic data acquisition while providing a wavefield that is optimally sampled by the receivers and sources so that the wavefield reconstruction is suitable for subsurface imaging needs.

    Abstract: The invention relates to a downhole inertial mass seismic-source system, apparatus and method for use within a wellbore environment to provide seismic signal energy at a wellbore location. The system comprises a first inertial mass apparatus with a fluid plunger that is in contact with a first wellbore fluid chamber and a second wellbore fluid chamber, a second inertial mass apparatus with a fluid plunger in contact with the first well bore fluid chamber, a third inertial mass apparatus with a fluid plunger in contact with the second well bore fluid chamber, an Inertial Mass Control System (IMCS) connected to the first inertial mass apparatus, and a power source providing power to the Inertial Mass Control System.
