  • Methods and systems of analyzing wellbore drilling operations
    Patent number: 9556728
    Abstract: A method for analyzing a wellbore drilling operation includes acquiring sonic log data, gamma ray log data, and rate of penetration (ROP) data. The sonic log data, the gamma ray log data, and the ROP data are associated with depth intervals of a wellbore. The method further includes determining unconfined compressive strength (UCS) of a rock formation associated with the wellbore using well log data and drilling data. The well log data is limited to the sonic log data and the gamma ray log data, and the drilling data is limited to the ROP data.

  • SHORT MATRIX DRILL BITS AND METHODOLOGIES FOR MANUFACTURING SHORT MATRIX DRILL BITS
    Publication number: 20150259985
    Abstract: A short matrix drill bit is disclosed along with methods of manufacturing the same. The Short drill matrix bit includes a combination shank/blank bonded to a matrix. The combination shank/blank includes a blank portion and a shank portion, which are formed as a unitary component. The combination shank and blank may also include an outer layer formed along at least a portion of the combination shank/blank. In some instances, the outer layer is nickel plating, or some other suitable material, which facilitates wetting of the binder material used to form the matrix.
