Abstract: Disclosed herein are digitalized blockchain-enabled asset tracking systems and methods to provide manufacturers, and other participants, with complete provenance of equipment in the system. This can include information such as location, ownership, warranties, service agreements, service history, and equipment status. The other participants in the system can also have the ability to add and/or modify immutable records, depending on the permissions assigned to each of the participants. Additionally, the disclosed systems and methods can generate history reports for each equipment unit registered with the system. The history reports can outline the entire equipment history, including all information written to the system during the equipment lifetime. In such a manner, the record of the equipment is stored in a singular, uniform format where it is easily accessible.

Abstract: A device for use during operation of a borehole survey probe or the like. The device is attachable to a flexible cable which in turn is connected to the survey probe, and the device includes an outer sealing or swab member and an interior valve. The valve and sealing member cooperate during pumping of the survey probe down through a conduit, and the valve opens during retrieval of the survey probe so that fluid in the conduit passes through the device as the survey probe is removed.

Abstract: A drilling fluid circulation system for containing drilling cuttings, gas and drilling fluid in a closed loop. The system includes a separator having two sealed compartments, one for settling out drilling cuttings and one for holding clean drilling fluid. A fine solids separator is provided between the two compartments, and a gas exhaust line for conducting gas released from the returning drilling fluid is provided to conduct the produced gas to a safe location away from the working area. A solids discharge device is provided for removing settled drilling cuttings.
