OFF-SHORE DRILLING AND PRODUCTION APPARATUS Filed Oct. 10, 1961 1N VEN TORS BY W United States Patent 3,215,202 OFF-SHORE DRILLING AND PRODUCTION APPARATUS Robert 0. Pollard, Downey, Charles E. Wakefield, Jr., Bakersfield, and Paul R. Rowley, Long Beach, Calif., assignors to Richfield Oil Corporation, Los Angeles, Calif., a corporation of Delaware Filed Oct. 10, 1961, Ser. No. 144,204 2 Claims. (Cl. 16666.5)
The present invention relates to off-shore drilling and more particularly relates to the installation of well drilling or production apparatus in a submarine well or onto a well-head mounted at the submarine well after contact with the well or well-head has been interrupted.
Drilling into a formation underlying a body of water such as the ocean from a drilling barge presents many difliculties due to movement of the floating drilling barge relative to the ocean floor due to tide and wave action. Time lost in attempting to re-enter a well bore drilled into the ocean floor or well-head equipment mounted thereon has substantially increased elf-shore drilling costs in the past. Damage to well-head equipment, and submarine control bases in attempting to re-enter such well bores has also been excessive and costly. The installation of drilling and production equipment, such as blowout preventers, casing risers, well-heads, or other tubular apparatus has heretofore been accomplished by guiding such equipment to the well from the barge by using cable guide lines which are attached to a well landing base and extend to the drilling barge and over which the drilling equipment can be guided until the equipment contacts the well-head apparatus. Cable guide lines, however, are subject to entanglement and lateral displacement due to ocean current, movement of the barge and flexibility in the lines. Even when the guide lines are tensioned at the vessel, heavy equipment, such as blowout preventers cannot be accurately guided into registry with the well. In well installations accessible to diving operations a diver may manually guide the drilling equipment onto the well, however diving operations are limited at depths of greater than 200 feet and impossible with presently available diving equipment at depths greater than 300 feet. During the drilling operation a stinger can be utilized to maintain entry into the well or well-head from the barge drilling apparatus and the apparatus lowered over the stinger into the well or onto the well head. Our present invention is an improvement on the above three methods for stabbing the blowout preventer or other tubular drilling apparatus onto the well-head.
It is an object of our present invention to provide an apparatus for installing drilling and production apparatus at a submarine well or well-head.
It is also an object of the present invention to provide apparatus for stabbing drilling apparatus such as a blowout preventer or tubular apparatus into a submarine well onto a well-head mounted at the well opening, without the use of guide lines.
It is a further object of our present invention to provide apparatus for laterally moving submarine drilling or production apparatus suspended over a submarine well to effect alignment therewith.
Other objects and a more complete understanding of our present invention may be had by reference to the following specification and the accompanying drawings in which:
FIG. 1 shows in elevation a blowout preventer to be guided onto a well-head.
FIG. 2 is a sectional View taken on line 2-2 of FIG. 1, and shows a power head utilized for laterally driving the blowout preventer into position over the well-head.
Patented Nov. 2, 1965 Briefly described, our present invention relates to the provision of apparatus remotely controlled for stabbing blowout prevention equipment, designated generally as 10, onto a submarine well head, designated generally as 12, by providing television apparatus mounted on a camera mount structure 14 which enables the operator on the barge to determine the relative positions of the blowout prevention equipment 10 and the well-head 12, and laterally move the blowout prevention equipment 10 with a power driven head 16 so that the blowout prevention equipment 10 can be moved to a position just over the well-head 12 and lowered thereonto.
Referring more particularly to the drawings, a landing base 18 is mounted at a submarine well bored in submarine formation 20. The landing base has a conductor pipe 22 extending therethrough intothewell. A conventional releasing joint 24 is provided to disconnect the well production head 26 from the conductor pipe which is cemented into the formation. Production head 26 has a landing mandrel 28 for latching the blowout prevention equipment 10 thereonto with a conventional latching gate 32. A guide funnel 30 may be used to assist in guiding the blowout prevention equipment 10 onto the landing mandrel 28 as the blowout prevention equipment is lowered onto the landing mandrel 28. The blowout prevention equipment is latched on the production head 12 by closing rams (not shown) of the gate latch 32 around the landing mandrel 28. The blowout prevention equipment may consist of any assemblage of conventional blowout preventers. The blowout prevention equipment shown in FIG. 1 employs a gate type blowout preventer 34 and a hydril or bag type blowout preventer 36.
The blowout prevention equipment 10 may be lowered from the drilling barge on a casing riser 38 as shown in FIG. 1 or it may be lowered on the drill pipe (not shown). A retaining ring 40 aflixed externally to the casing riser supports a retrievable camera mount or support 14 on a collar 41 which is slidable over the casing riser and supported from the barge with eye supports 43 and flexible cables 45 which may [be raised and lowered by hand or any suitable means, e.g. a power driven winch on the vessel (not shown). The camera mount 14 houses one or more television cameras 42 which may be circumferentially spaced around the camera mount to permit viewing of the location of the production head 26 relative to the blowout prevention equipment 10 so that as the blowout prevention equipment 10 is lowered from the barge onto the production head the entire lower end of the casing riser 38 with the blowout prevention equipment attached thereto may be guided by lateral movement thereof to effect alignment with the production head 26. As the blowout prevention equipment is lowered and laterally driven into proper alignment, the guide funnel 30 will encompass the production head 26.
The lateral movement of the lower end of the casing riser and/or the blowout prevention equipment may be accomplished by any type of lateral force generating means, such as power head 16 which is shown in plan view in FIG. 2. The power head 16 illustrated consists generally of one or more submersible motors 44 equipped with propellers 46 and circumferentially spaced about a body portion 17 to provide lateral drive for the blowout prevention equipment 10 in any lateral direction relative to the production head 26. Reversible motors may be utilized to facilitate lateral movement of the blowout prevention equipment and thereby reduce the number of motors required on the power head. Electric power cables 48 extending from the power head to the drilling barge may provide for control of the motors from the drilling barge or the motors may be located on the barge and the propellers driven through a suitable cable. Other lower end of the blowout prevention equipment include pumps or fluid jetting means operated either on the vessel or on the submersible power head.
Our present invention is utilized by an operator at the drilling barge observing with television cameras 42, the position of the blowout preventer equipment relative to the production head 12. With the knowledge of the relative positions of the production head and the blowout prevention equipment the blowout prevention equipment and the lower end of the casing riser can be late-rally driven with the power head 16 by causing one or more of the motors 44 to drive the power head laterally in the direction required to align the blowout prevention equipment onto the production head 12 as it is lowered thereto.
Although our present invention has been described with a certain degree of particularity in order to set forth the best known mode of operation, it is to be understood that the scope of our invention is not to be limited to the details set forth but should be afforded the full breadth of the appended claims.
We claim:
