Abstract: Techniques for synthetic data generation in computer-based reasoning systems are discussed and include receiving a request for generation of synthetic data based on a set of training data cases. One or more focal training data cases are determined. For undetermined features (either all of them or those that are not subject to conditions), a value for the feature is determined based on the focal cases.

Abstract: Bridging different standards or requirements documents originating from different participants in a drilling project to unify the standards or requirements provides more efficiencies and cost savings for the drilling project. The standards or requirements may be automatically analyzed to determine which standards or requirements from the participants are to be utilized for a given drilling project to generate a common bridged document of requirements and standards thereby aiding to reduce costs and establish a common understanding of the requirements and standards that are to be met or implemented during the drilling project by all participants. The automatic process may select those standards or requirements, or portions thereof that are more stringent.

Abstract: This disclosure presents an apparatus and system for lowering the cost of implementing a downhole sensor system using attachable collars. In some aspects, the attachable collar includes a transmitter component, while supporting electronics are included with a main collar, thereby reducing the cost of the attachable collar. The supporting electronics can send a transmission signal, a control signal, a synchronization clock signal, a selected transmission frequency, a sensor orientation and selection, and other instructions to the transmitter in the attachable collar. The receiver in the main collar can receive the output, as reflected by the subterranean formation, and transform the output to subterranean formation evaluation measurements. The measurements can be communicated to other systems. In some aspects, the attachable collar can include the receiver and the main collar can include the transmitter.

Abstract: A method of fabricating a ferrite for use in a resistivity logging tool includes providing an uncured ferrite material, and pressing the uncured ferrite material into a channel to form the ferrite. The channel is defined on a surface of a bobbin associated with the resistivity logging tool, and the channel can be arcuate and extend at an angle offset from a central axis of the bobbin. The uncured ferrite material is then cured in place within the channels on the bobbin.

Abstract: A measurement device can be provided for a tubular string of a drilling subsystem. The measurement device can include a transmitter and a receiver. A cover can be applied to at least one of the receiver or the transmitter. While at least one of the receiver or the transmitter is covered by the cover, an amount of crosstalk can be measured. The cover can be removed from the measurement device. Subsequent to removing the cover from the measurement device, an air-hang response of the receiver and the transmitter can be measured in an air-hang configuration of the tubular string. A corrected air-hang response of the measurement device can be determined by subtracting the amount of crosstalk from the air-hang response.
