摘要: This disclosure relates to a system and method for detecting structural integrity of a well casing. The system may detect casing structural integrity events. The casing structural integrity events may include structural failures of the casing and/or potential structural failures of the casing. The well casing may be drilled and/or otherwise embedded into a geologic structure. The well casing may be subject to geologic forces generated by the geologic structure. Unplanned and/or unexpected forces and/or movement may pose a risk to the structural integrity of the casing. Forces and/or movement of sufficient magnitude may result in damage to and/or destruction of the casing. Damage to and/or destruction of the casing may cause a loss of the natural resources being extracted via the well associated with the well casing, contamination of areas surrounding the well, undesirable surface expression, and/or other negative effects.

摘要: A method, system, and computer readable medium for managing drilling operations include calibrating a drilling model using collected drilling data, and executing, during a drilling operation, a simulation on the drilling model to generate a predicted measurement value for a drilling property. During the drilling operation and from a drillstring, an actual measurement value for the drilling property is obtained. Based on the actual measurement value matching the predicted measurement value, the simulation is extended to generate a simulated state of the drilling operation during the drilling operation, and a condition of the drilling operation is detected. A notification may be presented based on the condition during the drilling operation.

摘要: A system includes a tubular member (60) including a radially outer surface (60c) and a sensor assembly (128). The sensor assembly includes a strain sensor coupled to the radially outer surface. In addition, the sensor assembly includes a first coating having (134) a first hardness and a first tensile strength. The first coating encases the strain sensor (131,130) and at least part (64) of the outer surface. Further, the sensor assembly includes a second coating (136) having a second hardness that is greater than the first hardness and a second tensile strength that is greater than the first tensile strength. The second coating encases the first coating and at least another part (68) of the radially outer surface.

摘要: This invention relates to an articulating component (16) of a downhole assembly, and to a downhole steering assembly. There is provided an articulating component (16) having a first end (40) and a second end (42), the articulating component being adapted to transmit torque between the first end and the second end. The articulating component has a pivotable coupling (46) between its first and second ends and at least one control element for the pivotable coupling, the control element(s) having an active condition in which the pivotable coupling is substantially locked against pivoting movement, and an inactive condition in which the pivotable coupling is unlocked. In a downhole steering assembly the articulating component is located downhole of the steering component whereby to protect the steering component from unwanted vibrations generated downhole, or uphole of the steering component whereby to protect the steering component from unwanted vibrations generated uphole, or both.

摘要: A technique facilitates monitoring of strain related effects along a tubing string, such as a tubing string extending from surface equipment toward a sea floor in a subsea well application. A monitoring module is employed to monitor the strain related effects and may have a tubular structure. The monitoring module also has a reduced wall thickness region constructed to concentrate strain in this reduced wall thickness region. Additionally, the monitoring module comprises at least one sensor mounted to the tubular structure in the reduced wall thickness region for monitoring of strains.
