Latest Patents

One of Southland's latest patents is for a diamond cutting element. This invention involves a rotary drill bit that contains multiple cutting elements. Each cutting element features a stud and a cutting disk mounted on the stud. The cutting disk consists of a substrate and a diamond layer bonded to it. A relief is formed in the outer peripheral edge of both the substrate and diamond layer at the formation-contacting point, creating a pair of cutting points separated by the relief. The stud includes a channel aligned with the relief to conduct fluid for cooling and cleaning the cutting points. Additionally, the stud may have a fluid passage for directing drilling fluid directly to the channel.

Another significant patent by Southland is for an orientable fluid nozzle for drill bits. This nozzle comprises a nozzle body and a ring that secures the nozzle body within a threaded cavity of the drill bit. The nozzle body features a fluid passage of the orientable type. The ring consists of an externally threaded sleeve and a cap bonded to its front end. Both the cap and nozzle body are made from harder materials than the threaded sleeve. The cap contains dove-tail shaped slots that accommodate complementarily shaped projections on a tool, allowing the ring to be rotated relative to the nozzle body. By threading the ring into the cavity, the nozzle body can be secured with its fluid passage oriented as desired.
