Abstract: Blowout preventers having bodies without flanged necks are provided. In one embodiment, a blowout preventer stack includes first and second blowout preventers having independent and separable main bodies, each including a bore and a ram cavity transverse to the bore. The lower end of the main body of the first blowout preventer is fastened directly to an upper end of the main body of the second blowout preventer without a flanged neck extending the bore between the ram cavities of the first and second blowout preventers. In some instances, the main bodies of the first and second blowout preventers include external connection flanges that extend laterally from ram cavity body portions of the main bodies so as to enable connection of the two main bodies along the sides of the main bodies away from their bores. Additional systems, devices, and methods are also disclosed.

Abstract: A choke manifold and methods for assembling the same are provided. The choke manifold can include a choke line, a first pulsation dampener in fluid communication with the choke line, and a first choke valve in fluid communication with the first pulsation dampener. The first pulsation dampener is downstream of the choke line and up stream of the first choke valve.

Abstract: A method for drilling and producing a surface wellbore. The method can include drilling a conductor pipe borehole; installing a conductor pipe within the conductor pipe borehole; installing a drilling flange onto the conductor pipe; and assembling a wellhead stack on the drilling flange. The wellhead stack can include two or more blow out preventers, a kill line hub secured to and in fluid communications with a first spool located below a first blowout preventer, a choke line hub secured to and in fluid communications with a second spool located between a second blowout preventer and the first blow out preventer, a choke line, and a kill line, wherein both the kill line and choke line each have a quick connect collet connector. The kill line collet connector can be landed on the kill line and the choke line collet connector on the choke line hub.

Abstract: Components of drilling and production systems with wide flange bodies are provided. In one embodiment, an apparatus includes a component (40, 124, 126, 128) of a wellhead assembly (18) or of a riser (16) of a drilling or production system, the component having a non-tubular main body (42, 130, 140) and a bore (44, 132, 144) extending axially through the main body to allow fluids to flow through the main body via the bore. Rather than having a flanged neck fixedly extending the bore from the main body with a connection flange below or above the main body, the component includes a lateral flange (50, 134, 146, 160) extending outwardly from an exterior surface of the main body such that the lateral flange is positioned alongside the main body. Additional systems, devices, and methods are also disclosed.

Abstract: A guide funnel includes segments that have a funnel surface running at an oblique angle between a bottom end and an inner circumferential edge of the top end. The width of the funnel surface is sized so that, when the guide funnel is in an assembled state, a continuous or discontinuous funnel wall is formed between adjacent segments. The bottom end can include an arcuate-shaped ring segment that forms a portion of an outer periphery of the guide funnel. The top end can be sized so that when the guide funnel is in the assembled state a side of the top end abuts a side of an adjacent top end. An adaptor ring can be secured to the inner circumferential edge of the top end and later removed and replaced with another adaptor ring to provide a different size guide funnel.
