John D Jeter: Device for drilling a hole in the side wall of a bore hole. Texas Dynamatics, February 15, 1977: US04007797 (111 worldwide citation)

The device disclosed includes a housing which can be moved through the bore hole and anchored in the desired location for drilling a lateral hole. Located in the housing is a drill string guide or conductor having a bendable lower end. The conductor is movable to a position where its lower end is ei ...

John D Jeter: Stabilizer. Vaden Eickenroht Thompson Bednar & Jamison, March 16, 1982: US04319649 (55 worldwide citation)

The stabilizer disclosed includes a body for mounting on the drill string and a sleeve for mounting on the body to engage the wall of the well bore. The body is mounted eccentrically of the longitudinal axis of the drill string and the sleeve is mounted eccentrically to the longitudinal axis of the ...

John D Jeter: Drilling enhancement tool. John D Jeter, April 4, 1989: US04817739 (53 worldwide citation)

A drilling fluid pulse generator for use above a drill bit to produce pulsations in drilling fluid flow. An autocycling valve briefly interrupts the flow of fluid to bit jets to reduce the effective hydrostatic pressure at the drilling face and to hydraulic energy in the drill string to thoroughly s ...

Edward S Mumby, John D Jeter: Servo valve for well-logging telemetry. Exploration Logging, Christie Parker & Hale, May 31, 1983: US04386422 (50 worldwide citation)

A monostable valve for insertion in a drill string used in forming a borehole such as an oil well. In an open position, the valve vents drilling fluid flowing in the drill string to an annulus in the borehole for return flow to the surface, thus generating a surface-detectable negative fluid-pressur ...

John D Jeter, Leon M Earl, Merlin P Landry: Mud pulse pressure signal generator. The Bob Fournet Company, John D Jeter, April 7, 1992: US05103430 (29 worldwide citation)

A downhole signal generating mud pulser has a poppet and orifice signal valve to variably resist the drilling fluid stream. The poppet is upstream of the orifice and is moved by a piston in fluid communication with opposite flow related sides of the signal valve such that more pressure drop across t ...

John D Jeter: Well bore communication pulser. John D Jeter, December 5, 2006: US07145834 (28 worldwide citation)

The preferred pulser is a mud powered oscillator powered by the pressure variation produced across the signal valve by the unstable action. The signal valve comprises a poppet and cooperating orifice. The pressure drop across the orifice is used to urge the poppet away from the orifice and an opposi ...

John D Jeter, Henry S More: Well logging apparatus with replaceable sensor carrying insulating sleeve disposed in rotation restrained position around a drill string. Exploration Logging, Christie Parker & Hale, January 15, 1985: US04494072 (21 worldwide citation)

A replaceable insulating sleeve is disposed around the lower end of a drill string used in drilling a well. The sleeve is restrained from rotating relative to the drill string, but can be released and quickly slipped off the drill string in the field to permit rapid replacement if damaged, or if alt ...

John D Jeter: Well bore communication pulser. Ronald L Shaw, Clyde Cormier, December 5, 1995: US05473579 (21 worldwide citation)

A well communication pulser is solenoid controlled but energized by an actuator responsive to the pressure drop across the signal valve. The signal valve is spring biased toward a closed state but the actuator urges it toward an open state with a force proportional to the pressure drop. When in the ...
