摘要： A technique facilitates landing of a subsea component, e.g. a tubing hanger, by utilizing a poppet valve to provide an indication of proper landing. The poppet valve is combined with the tubing hanger or other subsea component and oriented to engage a corresponding landing surface. A pressure line is routed to the poppet valve, and the poppet valve is biased to an open flow position with respect to the pressure line during deployment. If the subsea component is properly landed, the corresponding landing surface is able to shift the poppet valve to a closed position. The closed position may be verified via pressure testing through the pressure line.

摘要： A test plug is proposed for inspecting the integrity of a cement plug or other barrier in an abandoned oil and/or gas production wellbore as well as its own sealing performance. The test plug employs a pair of expandable seals for sealing off an annular space between the seals, the plug and surrounding inner surface of the wellbore. Furthermore, it employs a pump for pumping fluid through a fluid channel traversing the plug into or from an intermediate wellbore section between the plug and the barrier. Valves are provided for closing the fluid channel after the pressure in the intermediate wellbore section has reached a selected level. Pressure gauges monitor a pressure in the intermediate wellbore section and in the annular space during a selected period of time. The monitored pressure is stored in a memory device and/or transmitted to a barrier and seal integrity monitoring display at the earth surface.

摘要： A method for sealing perforation tunnels in a well includes steps of pumping an initial volume of fluid into the well, mixing expandable material into a carrier fluid to form an expandable fluid mixture, pumping the expandable fluid mixture into the well to force the expandable material into the perforation tunnels in the well, and holding the expandable material under a hold pressure in the perforation tunnels for a cure period to form perforation plugs.

摘要： Provided is a method, system, and sensor device for collecting fluid data and fluid conduit data. The sensor device includes an outer capsule that is free flowing within the fluid and provides fluid-tight containment to an interior compartment, at least one sensor mounted within the interior compartment, wherein the at least one sensor senses fluid data and fluid conduit data, the sensed fluid properties being the collected fluid data, and a conductor for activating the at least one sensor to sense fluid data and fluid conduit data, wherein the conductor passes from the interior compartment and through the outer capsule.

摘要： A wellbore plug structure and a method for pressure testing a wellbore using the plug structure. The plug structure advantageously allows pressure testing of the wellbore casing without the use of a toe sleeve and without requiring the application of a pressure in excess of the wellbore pressure test after testing is completed. The wellbore plug structure includes a piston member that can be released at any time after placement of the structure in the wellbore casing to expose a dissolvable element to a pressurizing fluid. A pressure test may then be conducted before the fluid completely dissolves the dissolvable element. Once the dissolvable element is dissolved, a fluid pathway through the wellbore plug structure is created that many enable the placement of tooling through the plug structure.

摘要： A method of pressure testing downhole tubular connections includes connecting a pressure monitoring device to a test port on a downhole connector of a downhole tool, connecting the pressure monitoring device to a reference port, pressurizing the test port and the reference port, and monitoring for a pressure difference between the test port and the reference port with the pressure monitoring device.

摘要： Some examples of determining wellbore leak crossflow rate between formations in an injection well are described. During normal operation of an injection well, multiple bottomhole pressures are determined based on multiple surface injection pressures. An Inflow Performance Relationship (IPR) for the injection well is determined based on the multiple bottomhole pressures and the multiple injection flow rates. After shut-in responsive to a subsurface leak, the shut-in injection well is modeled as a producing well having the IPR determined during normal operation of the injection well. A crossflow rate in the injection well at a location of the subsurface leak in the injection well is determined based on the IPR of the modeled producing well.

摘要： A method and system for detecting material loss in a tubular. A method includes identifying a radial cross-sectional area of a tubular as having a loss of material in a wall of the tubular. Responsive to the identifying, an amount of voltage offset present in each of a plurality of measurement signals is determined. Each of the measurement signals provides measurement information for an arc section of the wall. For each of the measurement signals, a zero adjusted signal is produced by adjusting the measurement signal to remove the amount of voltage offset over a length of the tubular for which the identifying recognizes the loss of material. An assessment of wall material loss is produced for each arc section of the wall of the tubular based on the zero adjusted signals. An image of the wall of the tubular showing the wall material loss for each arc section is generated.
