Abstract: A gas vent system for use in a wellbore that includes a substantially horizontal portion is provided. The gas vent system includes a gas vent conduit positioned within the wellbore. The gas vent conduit defining a gas vent intake passage situated within the substantially horizontal portion of the wellbore and configured to facilitate a flow of gaseous substances therethrough. A gas vent valve coupled to the gas vent conduit and situated outside the wellbore. The gas vent valve controls the flow of gaseous substances through the gas vent conduit.

Abstract: An approach for supporting a wax pattern during investment casting. The approach described herein forms a support structure to support the wax pattern during investment casting. The support structure has a capping structure with a geometry that can match a profile of a lower region of the wax pattern, and at least one support brace extending outward from the support capping structure. The support structure can be placed on a surface of the lower region. The support capping structure can form a defined envelope to enclose the lower region of the wax pattern. The support structure is connected to a base plate by the support brace(s). The capping structure and the support brace(s) secure the wax pattern to the base plate and distribute the load of the wax pattern to maximize strength while minimizing the risk of a discontinuity in the wax or shell that could affect the casting process.
