Systems and methods for adaptive filtering of RSS pad noise and the detection of RSS pad seal leakage in real-time.

A smart device located in a wellbore head during production operations in a well is disclosed. The smart device has a transceiver that exchanges signals with a wellhead sensor, the wellhead sensor monitoring a hydraulic line with T-connection for bleed-off. The transceiver communicates with the wellhead sensor through a first communication link established by the smart device. A localization system identifies pressure information relating to information of the well, including sizes of an inner casing and of an outer casing of the well, and a processor implements a combination of artificial intelligence and machine learning to pre-emptively provide warnings relating to possible estimated CCA behavior. Report information is generated that includes whether a source from a bleed-off is downhole or from trapped compressed fluid due to heat expansion, and provides a forward plan for a remedial job based on previous history of similar CCA behavior in the well.

A test joint device installed in a well site includes a test joint with an outer diameter, a test plug disposed at a lower axial end of the test joint, a plurality of clamps configured to enlarge the outer diameter of the test joint; and a plurality of stop collars configured to retain the plurality of clamps in a vertical direction. A first clamp and a second clamp of the plurality of clamps are each attached to the test joint. The first clamp is configured to enlarge the outer diameter of the test joint to a first outer diameter and the second clamp is configured to enlarge the outer diameter of the test joint to a second outer diameter.

In an example method a system obtains first data regarding a first oil well, including one or more first thermal images of the oil well generated by one or more first thermal cameras. The system determines, using computerized neural network, a presence of a gas leak at one or more locations on the first oil well based on the first data. The one or more locations include at least one of a first location along a pipeline configured to convey gas to a flare area of the first oil well, or a second location at a rig floor of the first oil well. In response to determining the presence of the gas leak at the one or more locations, the system generates a notification indicating the presence of the gas leak at the one or more locations.

A method is for testing the pressure integrity of a barrier in an annulus outside a pipe string in a wellbore, the method including the steps of: establishing a fluid connection between an inside of the pipe string and an annulus out-side the pipe string at a first position and second positions in the wellbore, the second position being offset from the first position along the axial direction of the wellbore; establishing a temporary barrier between the fluid connections at the first and second positions in the wellbore; establishing a pressure differential across the temporary barrier; releasing a tracer from below the temporary barrier; and sniffing for tracer above the temporary barrier to verify a leakage through the temporary barrier and/or the barrier in the annulus. There is also disclosed a tool for executing such a method.

A system can provide for determining characteristics loss in a wellbore. The system can include a processor and a non-transitory memory with instructions that are executable by the processor for causing the processor to execute operations. The operations can include receiving, from sensors in a wellbore, data corresponding to loss indicators. The operations can include determining a loss probability for each loss indicator. The operations can include determining a total loss probability of fluid loss in the wellbore based on the loss probabilities. The operations can include outputting the total loss probability to be used in a drilling operation in the wellbore.
