DETAILED DESCRIPTION OF THE INVENTION

Described herein is a flow head system and method of use. The following description is presented to enable any person skilled in the art to make and use the invention as claimed and is provided in the context of the particular examples discussed below, variations of which will be readily apparent to those skilled in the art. In the interest of clarity, not all features of an actual implementation are described in this specification. It will be appreciated that in the development of any such actual implementation (as in any development project), design decisions must be made to achieve the designers' specific goals (e.g., compliance with system- and business-related constraints), and that these goals will vary from one implementation to another. It will also be appreciated that such development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the field of the appropriate art having the benefit of this disclosure. Accordingly, the claims appended hereto are not intended to be limited by the disclosed embodiments, but are to be accorded their widest scope consistent with the principles and features disclosed herein.

FIGS. 1A, 1B and 1C illustrate an elevated perspective overview, a cross-section perspective overview and a close-up cross-section perspective overview of an offshore facility 102. In one embodiment, said offshore facility 102 can comprise a flow head system 100, a derrick 104, a traveling block 106, a riser 108 (or casing), a string of pipe 110 (as is known in the art), a rig floor 112 and a crown 114. In one embodiment, said traveling block 106 or other heave compensation device (which may be included in said flow head system) can move on a vertical axis while said flow head system 100 can rotate about a vertical axis. In one embodiment, movement of said traveling block 106 and rotation of said flow head system 100 can be beneficial in relieving stress on said flow head system 100 and said string of pipe 110 due to water current changes, waves or other occurrence resulting in movement of said offshore facility 102. Said string of pipe 110 may comprise tubing, casing, landing string, workover riser, or drill pipe.

FIGS. 2A, 2B, 2C, 2D and 2E illustrate a series of perspective overviews of said flow head system 100. FIG. 2A illustrates a perspective overview of said flow head system 100 having a first set of components 201a, a second set of components 201b and a well control equipment 201c. FIG. 2B illustrates a perspective overview of said second set of components 201b. FIG. 2C illustrates a perspective overview of said first set of components 201a. FIGS. 2D and 2E illustrates a perspective overview and a cross-section perspective overview of said flow head system 100.

In one embodiment, said flow head system 100 can comprise said first set of components 201a, said second set of components 201b, a one or more bearings or other anti-friction rotational devices, and said well control equipment 201c; wherein, said first set of components 201a and said second set of components 201b can rotate independently of one another about a center axis 203. In one embodiment, said first set of components 201a can rotate in a first direction 205a and said second set of components 201b can rotate in a second direction 205b about said center axis 203, as illustrated. Likewise, said first set of components 201a and said second set of components 201b can rotate in the same direction at different rotary speeds.

In one embodiment, said flow head system 100 can comprise a one or more load diversion devices 280 comprising a lower load diversion device 202, a one or more lower load bypass devices 204, and an upper load diversion device 208. In one embodiment, said first set of components 201a can releaseably attach to said lower load diversion device 202. In one embodiment, said one or more lower load bypass devices 204 can comprise a first bail 204a and a second bail 204b. In one embodiment, said one or more lower load bypass devices 204 can releaseably attach to said lower load diversion device 202 and to said upper load diversion device 208, as discussed below. Thus, said flow head system 100 is capable of a load on said well control equipment 201c by attaching between said lower load diversion device 202 and said upper load diversion device 208 with said one or more lower load bypass devices 204.

Further, in one embodiment, said flow head system 100 can provide vertical movement by heave compensation and rotational movement by allowing said second set of components 201b to move independently of said first set of components 201a (and therefore of said string of pipe 110). In one embodiment, said second set of components 201b can comprise any load diversion device including but not limited to elevators, pieces of a load diversion device, wire rope slings, lift frames, tension frames.

In one embodiment, said second set of components 201b can comprise said lower load diversion device 202, said one or more lower load bypass devices 204, said upper load diversion device 208, a one or more upper load bypass devices 214 (comprising a first bail 214a and a second bail 214b), and a first pressure swivel components 212 (not illustrated here, see FIG. 4).

Prior solutions put forward a coiled tubing lift frame/tension frame/bail and elevator system/heavy duty slings that does not swivel, as well as a flow head system in which the load/weight of the pipe below the system is carried through the flow control devices on said flow head system. That is, prior solutions suspend a load through the well control equipment 201c which complicates work on said well control equipment 201c (or similar). Thus, in one embodiment said second set of components 201b can function as a bypass frame capable of supporting a load around said well control equipment 201c.

In one embodiment, said well control equipment 201c may include a surface flow head valve block, a surface tree, a valve block or other combination of valves, a BOP, a “stuffing box” or any type of equipment that could be suspended within said flow head system 100.

In one embodiment, said lower load diversion device 202 can comprise a one or more ears (which can comprise a first ear 260a and a second ear 260b). In one embodiment, said one or more lower load bypass devices 204 can attach to said lower load diversion device 202 by placing a first ear 260a through said first eye 240a and said second ear 260b through said first eye 240b. Likewise, in one embodiment, said upper load diversion device 208 can comprise a one or more ears (which can comprise a first ear 262a and a second ear 262b). In one embodiment, said one or more lower load bypass devices 204 can attach to said upper load diversion device 208 by placing said first ear 262a through said second eye 242a and said second ear 262b through said second eye 242b.
