Abstract: An alignment assembly for use with a well string having a downhole tool to be positioned within a cased wellbore. The alignment assembly may include an outer assembly, an inner assembly positioned at least partially within the outer assembly, a locator, and a compensator. The locator may releasably couple the outer assembly to the inner assembly and be shaped to engage with a shoulder of the casing to align the downhole tool with a location along the casing. The compensator may be coupled to the outer assembly, positioned about the inner assembly, and configured to limit relative axial movement between the outer assembly and the inner assembly.

Abstract: A method is to perform pulse power drilling of a borehole into a subsurface formation. The method comprises altering drilling the borehole, based on the pulse power drilling, in a direction that is off-center from a center of the borehole, wherein the altering of the drilling of the borehole in the direction that is off-center comprises articulating at least one element of a drill string having a drill bit; and periodically emitting a pulse of electrical discharge into the subsurface formation from at least one electrode of an electrode assembly that is part of the drill bit.

Abstract: An artificial lift assembly includes an outer body, an inner body positioned at least partially within the outer body, and a first line in fluid communication with a first reservoir defined at least partially between the outer body and the inner body. The first line is configured to introduce a working fluid into the first reservoir to cause an upstroke of the inner body relative to the outer body, the inner body moves upward with respect to the outer body during the upstroke, which draws a wellbore fluid into a chamber defined at least partially between the outer body and the inner body, and the chamber is positioned below the first reservoir.

Abstract: A technique facilitates production of desired well fluids from a lateral wellbore or wellbores. Aspects of the technique comprise drilling and completing the main wellbore which may include a lower lateral wellbore portion. A production deflector may be run downhole into the main wellbore, and then a lateral wellbore section, e.g. an upper lateral wellbore section, may be drilled from the main wellbore. A liner may then be run downhole and out into the lateral wellbore section. The liner comprises a scab portion which ends up disposed across the main wellbore. Subsequently, the scab portion is removed, e.g. milled, to enable communication with both the lateral wellbore section and the main wellbore extending below the lateral wellbore section.

Abstract: 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 swell able. The sealing element can create a seal, form an anchor, or create a seal and form an anchor in the wellbore after swelling.

Abstract: 向油气藏水层注水之油气开采方法，其特征是，在油气生产过程中，以一定速率向油气藏水层注水，补充水层水量不足部分，增强油气开采驱动力，弥补油气藏能量亏空，提高油气动用程度及采出程度，其中，所述增强油气开采驱动力，即，依据水流动特性及油气藏压力分布特征，向油气藏水层注水，增加油气藏水层势能，使油水界面向油气储层平稳推进，形成整体的水驱油气动力，当注水速度大于等于采油气速度，或者累注水量大于等于累积产油量与油气储层内存水量之差，形成由外向内的整体的水驱油气动力，形成强水驱；反之，则以弥补储层能量亏空为主，形成弱水驱。

Abstract: A method of measuring a rate of mineralization, including: positioning a seismic sensor and/or a harmonic sensor in acoustic communication with a rock formation; injecting carbon dioxide into a borehole in the rock formation; reacting the carbon dioxide with the rock formation to form mineralized carbon dioxide; measuring an acoustic activity generated in the rock formation with the seismic sensor and/or harmonic sensor during the reacting; calculating the rate of mineralization based on the acoustic activity; and adjusting a rate of carbon dioxide injection into the rock formation based on the calculated rate of mineralization.

Abstract: A tubular cleaning system includes a housing having an outer surface, an inner surface, and a recess. A deployable tool is arranged in the recess. A motor is arranged in a cavity formed the housing between the outer surface and the inner surface. An actuator is operatively connected between the motor and the deployable tool. The motor is selectively activated through a signal to extend the deployable tool.
