摘要： Selective stimulation ports including sealing device retainers and methods of utilizing the same are disclosed herein. The selective stimulation ports (SSPs) are configured to be operatively attached to a wellbore tubular that defines a tubular conduit. The SSPs include an SSP conduit, which extends at least substantially perpendicular to a wall of the wellbore tubular, and a sealing device receptacle, which defines at least a portion of the SSP conduit and is sized to receive a sealing device. The SSPs also include a sealing device seat, which is shaped to form a fluid seal with the sealing device. The SSPs further include a sealing device retainer, which is configured to retain the sealing device within the sealing device receptacle. The methods include methods of stimulating the hydrocarbon well utilizing the SSPs and/or methods of conveying a downhole tool within the hydrocarbon well utilizing the SSPs.

摘要： Corrodible wellbore plugs, systems and methods are disclosed herein. The methods include flowing a corrodible wellbore plug that is at least partially formed from a corrodible metal to a downhole location within a wellbore conduit and retaining the corrodible wellbore plug at the downhole location by operatively engaging an engagement structure with a wellbore tubular that defines the wellbore conduit. The methods include pressurizing a portion of the wellbore conduit uphole from the corrodible wellbore plug and flowing a corrosive reservoir fluid from the subterranean formation into contact with the corrodible metal to release the corrodible wellbore plug from the downhole location. The methods also may include removing the wellbore plug without utilizing a drill-out process. The systems include a corrodible wellbore plug that includes a plug body and a retention mechanism, which includes a slip ring formed from the corrodible metal and that includes the engagement structure.

摘要： The determination of axial and lateral displacement in a material subject to compression is determined by fitting a multi-dimensional model function to the match between corresponding portions of the material in two states of compression. In one embodiment, iso-contour lines in a correlation between a reference kernel and a target kernel are fit to an ellipse whose center defines the maximum correlation and hence the displacement.

摘要： The conveyor apparatus disclosed herein is generally formed of a first rail and a second rail, each rail having a plurality of rollers. A portion of the rollers are desirably drive rollers, receiving power from an integral motor assembly. The motor generally comprises a stator that is coupled to the rail and an outer roller assembly rotatably coupled to the rail. The roller assembly includes an outer circumferential magnetized portion positioned in surrounding engagement to the motor stator and functions both as the motor rotor and the conveying surface of the roller. Non-slip roller covering material may be attached to the exterior of the roller assembly. A circuit board having logic controls is preferably in communication with at least one sensor and the motor rotor to regulate rotation of the motor rotor during use of the conveyor.

摘要： A slip assembly apparatus is adapted (i) to be deployed into a wellbore (ii) to prevent axial movement of a downhole tool assembly in the wellbore when the slip assembly apparatus is actuated and external forces are imposed on the downhole tool assembly; (iii) to allow fluid flow past the slip assembly apparatus within the wellbore when the slip assembly apparatus is actuated or non-actuated; and (iv) to allow release of the slip assembly apparatus by use of a release load that is less than the axial capacity of the deployment mechanism. Different embodiments of the invention contain features such as claddings and treatments for surface hardness and wear resistance, and grooves or flutes for enhancing fluid flow between the outer diameter of the slip assembly and the inner diameter of the well casings.
