Abstract: A method may include obtaining, by a computer processor, seismic data regarding a geological region of interest. The method may further include obtaining, by the computer processor, well log data from a wellbore within the geological region of interest. The method may further include determining, by the computer processor, a formation top depth using the seismic data, the well log data, a stratigraphic column, and a machine-learning model. The stratigraphic column may describe an order of various formations within the geological region of interest. The machine-learning model may assign a feature among the seismic data and the well log data to a formation among the formations in the stratigraphic column to determine the formation top depth.

Abstract: A tooth tapering control guide can be used to create an accurate and consistent taper angle for a target tooth. The guide includes a telescoping member which may be secured to a tooth that is adjacent to the target tooth. The telescoping member includes an upper rod and a lower rod that are telescopically connected. The upper rod of the telescoping member is generally L-shaped, including a vertical portion and a horizontal portion that extends normal to the vertical portion. The horizontal portion includes a rectangular slot along its lower surface and a clasp rod that is slidable within the slot. The vertical portion telescopically receives the lower rod. The clasp rod includes a clasp at a lower end that is attachable to a drill. Once the drill clasp is secured to the drill, the drill bit can be maintained at a constant angle (e.g., 90 degrees) with respect to the target tooth.
