Side pocket mandrel with enhanced pressure rating

The pressure rating of a SPM assembly is enhanced by metal removal in one or more locations. The start of the pocket is reshaped from an elongated shape with a rounded end when viewed in section to a crescent shape from the onset of the pocket to the start of the seal bore in the pocket. Blind bores...

More Information
Summary:The pressure rating of a SPM assembly is enhanced by metal removal in one or more locations. The start of the pocket is reshaped from an elongated shape with a rounded end when viewed in section to a crescent shape from the onset of the pocket to the start of the seal bore in the pocket. Blind bores are disposed generally parallel to the seal bore to further remove bulk of the body portion in view of its asymmetrical design to accommodate the pocket. One or more of these body modifications gets the body reconfigured to be more symmetrical. The added symmetry acts to equalize the stresses all around the periphery of the body with the result being a higher pressure rating for a given outer dimension of the body as compared to the current known designs.
