Abstract: A system for connecting a cement string for a cementing operation, the system may include a casing spool and a lower quick connector attached to the casing spool, the lower quick connector comprising a lower body having an inner surface and at least one sealing element disposed on the inner surface of the lower body. The system may also include a cement adapter removably connected to the lower quick connector, the cement adapter comprising a cement adapter body having an outer edge that engages at least one sealing element and a radial protrusion extending outwardly from the cement adapter body and a connector clamp that engages the lower quick connector and the cement adapter to hold the cement adapter in place relative to the lower quick connector.

Abstract: Disclosed are systems and methods for connecting a hydraulic fracturing fluid source to various wells at a given well site. In general, use of disclosed systems and methods provide for repositioning (refocusing) the hydraulic fracturing operation amongst multiple wells may be achieved. In one example, a system to reroute fracturing fluid from a source to various wells at a well site may be provided. The use of adapters and quick clamp connections allow hydraulic fracturing fluid to be rerouted between various wells in a manner to decrease the cost and reduce hazards associated with changing hydraulic fracturing locations. Modular components of the system (and an overall modular design of the system itself) may allow a centralized manifold to be relocated to various locations at one or more well sites.

Abstract: A wellhead assembly uses a plurality of pins to secure a casing head to a mandrel during installation. The mandrel is installed onto a casing string with the casing head is positioned on the mandrel so as to align a plurality of through-holes with a groove encircling the mandrel. The plurality of pins are inserted through the through-holes and into the groove of the mandrel, locking the casing head onto the mandrel so drilling can occur. Installation and tear down are faster and less labor intensive.

Abstract: The present disclosure is directed to a locking assembly to attach a quickset casing head of a wellhead assembly to a landing mandrel attached to a surface casing in a drilling operation. A locking ring, comprised of a plurality of arcuate segments, is arranged between the quickset casing head and the landing mandrel. Each of the plurality of arcuate segments is clamped down onto the landing mandrel with a plurality of radially spaced lockdown bolts fastened through the quickset casing head. The clamping enables a seal between the quickset casing head and the landing mandrel without requiring arduous welding.
