    Abstract: Systems and methods for monitoring health of systems and components of an oil rig are disclosed. Monitoring usage parameters allows for a probabilistic way to determine when rig equipment will fail. A failure probability curve based on past performance of the equipment can be used. Multiple usage metrics allow for increased accuracy and certainty of a time of failure for the equipment. Using a sufficiently high number of usage metrics allows the failure probability range to be very narrow and therefore the certainty of the prediction is high.

  • Patent number: 11021944
    Abstract: Apparatus and methods regarding a processing system operable to implement an arbiter. The arbiter receives commands from non-prioritized and prioritized actors, and repeatedly issues an earliest received, non-issued command received from the non-prioritized actor. Execution of an immediately preceding issued command is completed or terminated by a sending actor of the immediately preceding issued command before a subsequent earliest received, non-issued command is issued. The arbiter also issues a command received from the prioritized actor upon receipt of the command received from the prioritized actor. Issuance of the command received from the prioritized actor interrupts issuance and execution of a command received from the non-prioritized actor. The commands from the non-prioritized and prioritized actors are issued to equipment controllers operable to control equipment of a well construction system.

  • Patent number: 11015996
    Abstract: A new approach to pipeline pigging using electro acoustic technology (EAT) is described in which the data from a pigging operation can be transmitted in real time to optical fiber on the outside of the pipeline and detected using distributed acoustic sensing (DAS) techniques, including the precise location, velocity and acceleration of the pig using the DAS technique. Thus the sensor data can easily be mapped to its precise location in real time. The EAT sensors use the DAS fiber as a data transmission line by converting electrical or optical signals to acoustic signals which excite the fiber and can be detected by an interrogator at the pig launch site.

  • Patent number: 10995606
    Abstract: Methods arc provided for using sonic tool data to investigate a multi-string wcllbore. The sonic data is processed to obtain indications of phase slowness dispersions for multiple locations in the wellbore. The dispersions are aggregated. The aggregated dispersions are compared with a plurality of cut-off mode templates to identify the presence of cut-off modes or the lack thereof in the aggregated phase slowness dispersions. Features of the multi-string wellbore are identified based on the presence of the cut-off modes or the lack thereof. In another method, the sonic data is processed to obtain indications as a function of depth of at least one of an energy spectrum, a semblance projection, a slowness dispersion projection, an attenuation dispersion projection, and a wavenumber dispersion projection. The indications are inspected to locate a shift at a particular depth indicat- ing a transition in at least oneannulus of the multi-string wellbore.
