1. A running tool for installing casing in a wellbore, the running tool comprising:
a tubular body having a longitudinal axis and providing a sidewall defining an interior wall and an exterior wall opposite the interior wall;
an upper connector defined at an upper end of the tubular body for coupling with an upper portion of a casing string;
a lower connector defined at a lower end of the tubular body, the lower connector operable to releasably couple the tubular body to a casing hanger in an axially approximated position and an axially displaced position with respect to the casing hanger; and
a plurality of circulation ports defined in the sidewall and circumferentially spaced around the tubular body, each circulation port extending between the interior and exterior walls, and at least a portion of at least one circulation port extending along a trajectory obliquely arranged with respect to a radial direction defined by the tubular body to direct fluid expelled through the at least one circulation port along the exterior wall of the tubular body,
wherein the at least two circulation ports are oriented along opposite oblique angles with respect to the radial direction.
