Method for completing an underwater well includes locating drilling apparatus at the well site, and installing conductor casing in the floor of the body of water with a wellhead, blowout preventer stack, and riser attached thereto at a point near the floor, with the riser extending upwardly to the drilling means. A drill string and standard 171/2 inch drill bit is then run through the wellhead and conductor casing, and a hole is drilled for suspending 16 inch casing within the wellhead and conductor casing. A hanger-support member having a casing string attached thereto is lowered into the well until it lands in the wellhead, and it is then rotated less than 360. degree. to connect it within the wellhead. The hanger-support member is then latched within the wellhead. A hole is then drilled for suspending another casing within the wellhead, and a casing hanger with casing string is run through the riser and into the wellhead, and the casing hanger is landed on the hanger-support member.

A fire responsive stem retention apparatus for a non-rising stem valve including an outer hollow sleeve secured to the top of the valve bonnet around the valve stem. An inner cap is received in the outer hollow sleeve and closely fitted therewithin, and houses upper and lower stem bearings therein. The inner cap has a shoulder which provides an upper support for the upper stem bearing. Under normal environmental conditions, the inner cap is sweated to the outer sleeve with a thin layer of fusible material. The upper bearing and stem are prevented from moving upward by the shoulder on the inner cap, and an annular shoulder on the stem is prevented from engaging a backseat in the bonnet. Under fire conditions, the thin layer of fusible material melts rapidly, freeing the inner cap from the outer sleeve and permitting the stem to rise until the annular shoulder on the stem engages the backseat in the bonnet. A screw in the inner cap rides in a slot in the outer sleeve, preventing removal of the inner cap from the sleeve.

A breech block hanger support member for a subsea wellhead assembly for wells having a working pressure up to approximately 15,000 psi. The assembly includes a wellhead, the support member, a packoff for sealing the support member, and one or more other casing hangers supported by the support member. The support member is connected to the wellhead for itself suspending casing, for supporting at least one other casing hanger and casing, and for containing the working pressure. Breech block teeth are provided on the wellhead and support member to permit the support member to be stabbed into the wellhead and rotated less than 360. degree. for completing the connection therebetween. The teeth include groupings of spaced-apart no-lead teeth having slots therebetween. The slots provide a flow way for passing well fluids. The support member further includes an upper annular flange for arresting its downward movement within the wellhead.
