Abstract: A measurement while drilling (MWD) system for use in a drilling string, the MWD system comprises: a resistivity module that is configured to generate resistivity information about a resistivity of a formation that is drilled by the drilling string; a near bit sub that is configured to generate inclination information about an inclination of a drill bit of the drilling string; a MWD module; a first wireless communication module that is configured to wirelessly send the resistivity information from the resistivity module to the MWD module; a second wireless communication module that is configured to wirelessly send inclination information from the near bit sub module to the MWD module; and wherein the MWD module is configured to participate in a transmission of the inclination information and the resistivity information towards an upper surface of the formation.

Abstract: A drilling system that may include a drilling element for drilling a hole in a geological formation; a sensor module arranged to collect information about the drilling; a transmitter that is arranged to receive the information from the sensor module, amplify the information by a super-capacitor amplifier to provide amplified information and to provide the amplified information to a first element and to a second element of an antenna, the first and second elements of the antenna are located at two opposite sides of a band gap; wherein the antenna is arranged to transmit the amplified information via the geological formation; wherein the super-capacitor amplifier comprises a plurality of switched capacitor converters, each switched capacitor converter comprises a plurality of converter stages, each converter stage comprises capacitors and switches that are arranged to perform a current amplification of an input signal; wherein each converter stage is arranged to operate with alternating charge cycles and discha

Abstract: An electric dipole transmission system includes an uphole dipole assembly adapted for receiving downhole telemetry data. The uphole dipole assembly includes a gap sub, an electric dipole transmitter, a battery stack and a wireline receiver. A short hop receiver assembly is connected to the lower end of the uphole dipole assembly by a wireline. A downhole dipole assembly operatively connected to the uphole dipole assembly includes a short hop transmitter, a battery stack and a sensor assembly.
