A gravel pack tool for use in a well including a base pipe selectively deployed in the well that defines an outer annulus between the base pipe and an inner wall of the well, a dissolvable plug in a side wall of the base pipe, and tubing positioned within the base pipe that is in selective communication with a source of a bead forming fluid. When the bead forming fluid flows through the tubular and into the well, compounds in the bead forming fluid react to form beads within the outer annulus. The beads collect along a screen that circumscribes the base pipe and define a gravel pack which through which formation fluid is directed prior to entering production tubing in the wellbore. |

The apparatus includes a cap sub, vertical support member, a horizontal support member, a base member, and a hydraulic cylinder. The lifting device is attached to a wellhead assembly through a cap sub. The base member is attached to the cap sub through an enlarged ring. The base member also includes an elongated projected portion. The vertical support member is rotatably retained within a bore in the elongated projected portion. The proximal end of horizontal support member is connected to the upper end of the vertical support member. The hydraulic cylinder, which includes a hydraulic head and a hydraulic piston, is connected to the distal end of the horizontal support member. The vertical support member is capable of being rotated about the base member. The hydraulic cylinder is actuated to raise or lower a cap onto a cap sub, which is removably attached to a wellhead assembly. The vertical support member may be locked into place in a cap-engagement position or a non-cap engagement position through use of a spring-loaded locking pin which is inserted into a locking bracket on the vertical support member and into a recess on the base member. |

An anchoring device releasably secures the valve module in the flow passage. A method of constructing a riser system includes the steps of installing the valve module in the flow passage, and installing at least one annular seal module in the flow passage. The annular seal module is operative to prevent fluid flow through an annular space between the riser string and a tubular string positioned in the flow passage.
