    摘要: Techniques according to the present disclosure include moving an untethered downhole tool through a wellbore between a terranean surface and a particular depth in the wellbore; during the moving the untethered downhole tool through the wellbore, acquiring a set of sensed data from one or more sensors in the untethered downhole tool in a time domain; transforming the plurality of data values associated with the wellbore parameter in the time-domain into a plurality of data values associated with the wellbore parameter in a depth-domain based at least in part on at least one accelerometer output and the locations of a plurality of casing collars; and preparing the plurality of data values associated with the wellbore parameter in the depth-domain for presentation on a graphical user interface (GUI).

    摘要: Systems and methods for a guided extend reach tractor are disclosed. The method includes installing a packer and a tractor string operatively connected to the packer in a borehole; lowering the guided extend reach tractor into the borehole; supplying power, via a power source, to the guided extend reach tractor; attaching the guided extend reach tractor to the tractor string using an electromagnet; and clamping the guided extend reach tractor onto the tractor string. The method further includes activating helical bars to propel the guided extend reach tractor forward or backward in the borehole; performing well intervention operations in the borehole; and extracting the guided extend reach tractor from the borehole.

    摘要: A method for removing a flapper seat assembly that is replaceable from a safety valve positioned downhole in a wellbore is described herein. For example, the safety valve is positioned downhole in a wellbore and can include a housing. Additionally, the safety valve can include a flow tube coupled to a downhole tool. The flow tube can be removed from the safety valve in response to a first force applied by the downhole tool. A first tool profile can be coupled to a first assembly profile for coupling the downhole tool to the flapper seat assembly after removing the flow tube. A second assembly profile can be detached from a housing profile to remove the flapper seat assembly from the wellbore in response to a second force applied by the downhole tool. After removing the flapper seat assembly, a second flapper seat assembly can be attached to the safety valve.

    摘要: A pressurizable assembly which comprises first and second assemblies. The first assembly has a plurality of cam grooves while the second assembly is size and shaped to intimately receive and mate with the first assembly. The second assembly has a connection member a plurality of radially mounted locking pin mechanisms for interacting with one of the plurality of spaced apart cam grooves. Axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the cam grooves to an intermediate locking position which locks the second assembly with the first assembly, while a subsequent axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the plurality of cam grooves and disengage the second assembly from the first assembly.
