Abstract: A transmitter for inground use controls a depth signal transmit power in relation to a data signal transmit power such that one reception range of the depth signal at least approximately matches another, different reception range of the data signal. A portable device can form a system with the transmitter in which the portable device scans a plurality of frequencies within at least one low frequency depth signal range to measure the electromagnetic noise at each one of the plurality of frequencies and identify at least one of the frequencies as a potential depth frequency for the transmitter. The portable device can include a dual mode filter having a rebar mode and a normal mode filter. The depth signal frequency is dynamically positionable in relation to low frequency noise.

Abstract: An apparatus and method for operating a new well includes receiving a plurality of data relating to drilling operations from a plurality of wells in a region, the data including data from a plurality of sensors at each of the plurality of wells and data regarding equipment used for the drilling operations at each of the plurality of wells. A plurality of parameters is calculated based on the collected data from the plurality of wells. At least one equipment and at least one operating parameter are identified to use for drilling operation of the new well within the region based on the received data and the calculated parameters. The identified at least one equipment and at least one operating parameter are applied to use for the drilling operation of the new well.

Abstract: A system and method of steering a drill string when forming a wellbore in a subterranean formation. The method includes identifying two or more parameters associated with steering the drill string in a subject well; determining, via a statistical model, individual contributions to a tool yield model by each of the identified parameters; and suggesting, based on the statistical model and on current values of the identified parameters, one or more changes in the identified parameters, the changes sufficient to alter a trajectory of the drill string in the subject well.

Abstract: Disclosed is a method for reducing friction in a radial drilling application. The method involves coating the interior of a deflector shoe with a lubricant. Lubrication of the deflector show can be accomplished by applying a wet lubricant to the interior of the deflector shoe or spraying a dry lubricant on the interior of the deflector shoe. The method can further include coating a hose and/or a jet nozzle, passing the hose and/or jet nozzle through the coated interior of the deflector shoe. The method can further include coating components of a milling cutter, and passing the components of the milling cutter through the coated interior of the deflector shoe. An apparatus for reducing friction in a radial drilling application is also disclosed.

Abstract: A magnetic ranging system for use with a drilling assembly in a borehole in a formation, the drilling assembly including a drill string, a drill bit and a bottomhole assembly (BHA) connected to the drill bit, the BHA including a measurement-while-drilling (MWD) system, a bi-directional MWD telemetry interface, and a steerable component, may comprise at least one ranging magnetometer incorporated into the BHA. The ranging magnetometer may be configured to collect ranging measurements from behind the drill bit and the ranging magnetometer may be configured to transmit measurement data. The magnetic ranging system may include at least two ranging magnetometers, with one ranging magnetometer positioned above the MWD system and one ranging magnetometer positioned below the MWD system.

Abstract: Integrated dynamic impact or risk maps can be generated using borehole operation parameters, with associated impact parameters (representing a severity of an event) and softness parameters (representing a range or a percentage of the impact while not exceeding a critical threshold or an impact transition mechanism). As borehole operations are in progress, factors change over time, such as a change in depth, a change in temperature, a change in drilling fluid composition, the number of rotations, and other drilling and environmental factors. As these factors change, the associated impact and softness parameters can be dynamically updated with the current information. The resulting generation of dynamic impact or risk maps using this information is therefore updated to represent the most current conditions. The dynamic impact or risk maps can be utilized to determine modifications to borehole operations to reduce risk, costs, maintenance downtime, and improve return on investment of the borehole.

Abstract: The present invention is in the field of geological exploration and particularly relates to a method and system for gamma ray (GR) while drilling parameter data optimization for deep-filed oil and gas precise navigation, aiming to solve the problem of insufficient measurement accuracy of the depth of a well in the existing drilling technology. The present invention comprises: eliminating outliers from the obtained GR while drilling parameter data and determining the rationality of the eliminated outlier; performing derivation on a real-time updated variance attribute while drilling curve to obtain a real-time updated formation change-point detection result; searching the formation change-point detection result of a pre-drilling predicted well curve; and correcting the drilling depth by comparing the two formation change-point detection results to obtain the accurate depth while drilling.
