A wellbore system includes a lock ring forming at least a portion of a sealing assembly, the lock ring being coupled to and axially lower than one or more components of the sealing assembly to be positioned within an annulus. The wellbore system also includes a pedestal coupled to the lock ring, the pedestal arranged axially lower than at least a portion of the lock ring, the pedestal to be installed within the annulus. The wellbore system further includes a shoulder formed on at least a portion of a hanger. The wellbore system also includes a debris pocket formed within the annulus, the debris pocket arranged axially lower than both the shoulder and a lock ring groove.

Methods for positioning an expandable metal sealing element in the wellbore. An example method includes an expandable metal sealing element having a reactive metal and disposed in a location. The method further includes actuating a washout prevention element, contacting the expandable metal sealing element with a fluid that reacts with the reactive metal to produce a reaction product having a volume greater than the reactive metal, and allowing the washout prevention element to prevent at least a portion of the reaction product from flowing away from the location.

Methods of capturing carbon dioxide in a wellbore can include installing a sealing element in the wellbore. The sealing element swells in the presence of carbon dioxide and can be used for capturing the carbon. The sealing element can include a carbon-swelling material, such as a carbon-swelling polymers, metal-based materials, or combinations of elastomeric polymers and metal-based materials. The sealing element can also include combinations of different carbon-swelling materials, fillers or other compounds, and materials that are not carbon swellable. The sealing element can create a seal, form an anchor, or create a seal and form an anchor in the wellbore after swelling.

Seal elements for establishing fluid seals in a wellbore may be constructed of expandable metal materials. For example, an elongated gland of expandable metal may replace some or all the components in a packing stack of a locking mandrel. The gland may be recessed within the locking mandrel, or narrower than a seal bore of a landing nipple, such that the gland is protected from damage as the locking mandrel passes through landing nipples to reach a target landing nipple. The expandable metal may be induced to chemically react with a brine or other water-based fluid to form metal hydroxides and may thus create a seal with the target landing nipple. Once an intended purpose of the locking mandrel has been achieved, a pressure reversal may be employed to break the seal and/or a mild acid may be introduced to accelerate dissolving of the expandable metal seal,

Systems and methods for deployment of electric-based fracturing tools in vertical wells are disclose. A method of electric-based fracturing may include lowering an electrical stimulation tool into a wellbore using a drill pipe and isolating a lower portion of the wellbore that is downhole from an upper portion of the wellbore. The electrical stimulation tool may be disposed in the lower portion of the wellbore. A system for electric-based fracturing may include an isolation mechanism and an electrical stimulation tool. The isolation mechanism may be configured to expand from a retracted configuration spaced from an interior surface of a wellbore to an expanded configuration in contact with the inner surface of the wellbore. The electrical stimulation tool may be operatively coupled with the isolation mechanism and may be configured to be disposed distally relative to the isolation mechanism when positioned in the wellbore.

A wellbore assembly includes a cable and a wellbore tool. The wellbore tool is coupled to the downhole end of the cable. The wellbore tool includes a housing, one or more sensors, a packer, and a controller. The one or more sensors are coupled to the housing or to the cable or both. The sensors detect one or more parameters of the wellbore tool or the cable or both. The controller is coupled to the housing. The controller is electrically coupled to one or more sensors and is operationally coupled to the packer. The controller determines, with the wellbore tool parted from the cable and based on information received from the one or more sensors, an indication of the wellbore tool in free fall. The controller activates, based on the determination, the packer to expand the packer and set the wellbore tool on a wall of the wellbore.
