Abstract: An additive manufacturing (AM) system includes a housing defining a chamber, a build platform disposed in the chamber at a first elevation, and a lower gas inlet disposed at a second elevation and configured to supply a lower gas flow. The AM system includes a contoured surface extending between the lower gas inlet and the build platform to direct the lower gas flow from the second elevation at the lower gas inlet to the first elevation at the build platform, where the contoured surface discharges the lower gas flow in a direction substantially parallel to the build platform. The AM system also includes one or more gas delivery devices coupled to the lower gas inlet to regulate one or more flow characteristics of the lower gas flow, and a gas outlet configured to discharge the lower gas flow.

Abstract: A recoater for an additive manufacturing apparatus includes a recoater arm and retainer operably coupled with the recoater arm. The retainer includes a housing defining a cavity. A blade carrier supports one or more blades. An actuator is operably coupled with the housing and is configured to compressively retain an upper portion of the blade carrier within the cavity between a slide of the actuator and the housing.

Abstract: An additive manufacturing (AM) system includes a housing defining a chamber, a build platform disposed in the chamber at a first elevation, and a lower gas inlet disposed at a second elevation and configured to supply a lower gas flow. The AM system includes a contoured surface extending between the lower gas inlet and the build platform to direct the lower gas flow from the second elevation at the lower gas inlet to the first elevation at the build platform, where the contoured surface discharges the lower gas flow in a direction substantially parallel to the build platform. The AM system also includes one or more gas delivery devices coupled to the lower gas inlet to regulate one or more flow characteristics of the lower gas flow, and a gas outlet configured to discharge the lower gas flow.

Abstract: According to one embodiment, there is provided herein a system and method for producing a well lifecycle lift plan that includes considerations of multiple types of lift, multiple lift configurations associated with each lift type, and can be used to provide a prediction of when or if it would be desirable to change the lift plan at some time in the future. Another embodiment utilizes a heuristic database with rules that might be used to limit the solution space in some instances by restricting the solution to feasible configurations. A further embodiment teaches how multiple individual well optimization results might be combined with a reservoir model to obtain an optimized lift schedule for an entire field.

Abstract: The present disclosure relates to the manufacture and use of an additive manufacturing (AM) system that employs a spacer flow guide disposed or formed within a housing that defines a chamber of the AM system. The spacer flow guide may direct various portions of a gas flow within the chamber to respective exhaust channels. For example, in combination with portions of the housing, the spacer flow guide may define a main exhaust channel that extends between the chamber and a gas outlet formed in a downstream end of the housing. Additionally, a bypass exhaust channel may be defined between the chamber and a back surface of the spacer flow guide to fluidly couple an upper portion of the chamber to the main exhaust channel.
