Abstract: The trip system closely monitors and ensures that the hydrostatic pressure of the wellbore stays consistent throughout the tripping process, stripping process, and axial pipe operations. The core components of the system include, but are not limited to, an advanced automation system that controls a back-pressure device, including but not limited to a choke, a rotary ball valve, or other flow control devices. The automation system also monitors upstream and downstream flow measurement components. The trip system also provides a pump system to circulate drilling fluid from the trip tank across the top of the wellhead and/or at a lower portion below the RCD.

Abstract: Disclosed is a metal golf club head with optimum macro- and micro-structures and properties and a method for manufacturing a metal golf club head. The method comprises forging precisely a metal billet at a temperature between 35-47% of the melting temperature into a net or near-net lower portion shape comprising a face portion, a hosel portion, and an integrated sole and wall portion. The forging process is preferably performed in at least two stages, with the top stage forging a pre-form shape approximately equal to 60-80% of the final shape. The second stage of the forging process results in the net or near-net shape with only localized conditioning by machining or grinding. A crown portion is manufactured by stamping or forging, and then welded to the lower portion to form the metal golf club head.
