Abstract: A system and method for covering a cellar (49) at a wellhead to prevent and control fluids and gasses from the cellar (49). The covering includes a mat (50) that circumscribes a wellhead tubular that projects upward from the cellar (49). A split seam (80) in the mat (50) extends radially from the opening to the mat (50) outer periphery which allows the mat (50) to be placed around the wellhead tubular. A fastener joins the ends of the mat (50) that meet at the split seam. The mat (50) includes a collar (82), which mounts to the mat (50) along the opening and extends axially away from an upper surface of the mat (50). The collar (82) is secured to the wellhead tubular with a strap. Two discharge lines project through the mat (50) into the cellar (49), one for pumping into the cellar (49), and one for withdrawing fluid that has collected in the cellar (49).

Abstract: A guide assembly for a downhole tool and related method is disclosed. The guide assembly comprises a guide housing, flappers, and a driver. The guide housing has a passage to receive the downhole tool therethrough.. The flappers are movably positionable about the passage to selectively reduce an inlet thereto. The driver comprises a translator rotationally coupled to the flappers via the rods and an actuator to rotate the translator. The flappers are rotatable between the closed and the open position by the driver whereby passage of the downhole tool into the passage is selectively permitted. The translator may be a cam, gear, or rotary driver. The actuator may axially or rotationally drive the translator.
