Abstract: Completion systems and methods to complete a well are disclosed. A method to complete a well includes installing a casing across a plurality of zones of a well. The casing includes an opening and a sleeve positioned inside the casing. The method also includes shifting the sleeve from a first position to a second position to uncover the opening to provide fluid communication from a zone of the plurality of zones to the casing. After shifting the sleeve from the first position to the second position, the method includes flowing a screen assembly having a filter inside the casing and toward the sleeve. The method further includes positioning the filter around the opening and sealing the screen assembly around the opening to confine fluid flow through the opening to flow through the filter.

Abstract: The disclosed embodiments include methods to obtain measurements of a wellbore and data logging devices. In one embodiment, the method includes measuring, by a sensor of a wellbore isolation device, at least one condition of the wellbore proximate to the sensor. The wellbore isolation device has a dissolvable portion, and the sensor is releasable from the wellbore isolation device upon dissolution of the dissolvable portion. The method also includes storing measurements of the at least one condition of the wellbore in a machine-readable medium. The method further includes providing the stored measurements of the sensor to a controller following dissolution of the dissolvable portion.

Abstract: The disclosed embodiments include a wellbore isolation device, a method to form the wellbore isolation device, and a downhole, device-tracking system. In one embodiment, the system includes a wellbore isolation device having a first identification tag and a dissolvable component. The first identification tag is operable to travel along a fluid flow path toward the surface of a well upon dissolution of the dissolvable component. The system also includes a detector disposed along the fluid flow path, where the detector is operable to detect the first identification tag when the first identification tag is proximate to the detector.

Abstract: A collapsible baffle sub installable within a casing string of a hydrocarbon well. The collapsible baffle sub includes a movable sleeve and a collapsible baffle. By moving the sleeve from a first to a second position using a setting tool, the collapsible baffle is permitted to collapse within the collapsible baffle sub. Once collapsed, the collapsible baffle may receive an untethered object, such as a ball, forming a seal between the untethered object and the collapsible baffle and isolating sections of the wellbore for treatment.

Abstract: An example downhole tool includes a wellbore isolation device that provides a plurality of components including one or more first components and one or more second components. Each component is made of a degradable material that degrades when exposed to a wellbore environment, and the one or more first components degrades at a first degradation rate while the one or more second components degrades at a second degradation rate that is slower than the first degradation rate.

Abstract: A deployable baffle apparatus installed in a casing to isolate sections of a wellbore during stimulation treatments. The deployable baffle is inserted and positioned within a wellbore by a setting tool. To deploy the deployable baffle, the setting tool expands an expandable section of the deployable baffle such that the outer wall of the expandable section contacts an inner surface of the casing. Once the deployable baffle is deployed, the deployable baffle is detached from the setting tool and the tool sting may be repositioned for other downhole operations or removed from the wellbore. The deployable baffle includes an inner baffle for receiving an untethered object such that a seal is formed between the inner baffle and the untethered object, permitting isolation of adjacent wellbore sections. Any or all of the deployable baffle and the untethered object may be made of a dissolvable material.

Abstract: Disclosed is a wellbore configuration for use in coal bed gas production comprising tubing and down hole equipment made from non-sparking materials which can be mined out with the coal.

Abstract: Circulation flow apertures in a wellbore pipe, tubing, casing or casing liner screen may be selectively closed by an internal pipe sleeve that is formed of a thin, malleable material. One axial end of the sleeve is flared and secured to the inner bore surface of the pipe as by welding or by clamping between the ends of axially adjacent pipe joints joined by a threaded coupling. The remaining length of the sleeve extends along the pipe and over any pipe apertures to form an annular space between the outer cylinder surface of the sleeve and the inner bore surface of the pipe. A perimeter seal element such as an O-ring is placed around the sleeve outer perimeter beyond the apertures in a direction opposite from the sleeve flare. The flow aperture in the pipe is closed by a swaging tool that expands the sleeve against the pipe bore wall sufficiently to close the annulus and compress the O-ring seal against the pipe borewall.
