Benefits of technology
This patent is related to an autonomous logging drone tool-string and an autonomous logging drone for cementing a wellbore and logging wellbore information. The tool-string includes a wiper plug, a logging tool, and a transmitter capsule that is connected to the logging tool and can detach from it. The drone is used to pump cement down a wellbore casing and collect wellbore information, which can be stored and later retrieved. The technical effects of this patent include improved wellbore information collection and more efficient wellbore construction.

Embodiment Construction
[0007]In an aspect, the disclosure relates to an autonomous logging drone tool-string. The autonomous logging drone tool string may comprise a wiper plug at a downstream end, a logging tool, and a transmitter capsule in electrical communication with the logging tool. The transmitter capsule may be configured for detaching from the logging drone tool-string.
[0008]In an aspect, the disclosure relates to an autonomous logging drone that may comprise a wiper plug, a perforating gun, a trigger module, a logging tool, and a transmitter capsule. Each of the wiper plug, the perforating gun, the trigger module, the logging tool, and the transmitter capsule may be connected as a tool-string, and the wiper plug may be positioned at a downstream end of the tool-string.
[0009]In an aspect, the disclosure relates to a method for cementing a wellbore and logging wellbore information. The method may comprise pumping cement down a wellbore casing within the wellbore and deploying a logging drone into...

An autonomous logging drone tool-string including a wiper plug at a downstream end, a logging tool, and a detachable transmitter capsule, and associated methods for cementing a wellbore and logging wellbore information in a single tool-string run downhole. In an aspect, the logging drone tool-string may include a perforating gun and associated methods may include perforating a toe end of the wellbore casing and surrounding cement. In an aspect, the transmitter capsule stores wellbore information from the logging tool. The transmitter capsule may be detached, pumped to the surface, and retrieved for accessing the stored wellbore information.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application No. 62 / 957,381 filed Jan. 6, 2020. This application claims the benefit of U.S. Provisional Patent Application No. 63 / 040,393 filed Jun. 17, 2020. The entire contents of each application listed above are incorporated herein by reference.BACKGROUND OF THE DISCLOSURE[0002]The present disclosure is generally directed to wellbore completion operations. As shown in the cross-sectional view of FIG. 1, a typical wellbore site 100 includes a wellbore 101 that has been drilled into a hydrocarbon formation 130 and extends from a surface 110 of the wellbore 101 / hydrocarbon formation 130 to an end, or toe 111, of the wellbore 101. As part of preparing the wellbore 101 for perforating and completion operations to extract oil and / or gas from the hydrocarbon formation 130, a wellbore casing 120, as multiple segments, is inserted into the wellbore 101. The configuration / profile of ...
