Definitions
- the present invention is directed to a method of exploitation of hydrocarbon reservoirs and the like in deep water. More particularly, the invention is concerned with making a connection to an underwater well to a location which is accessible from the water surface. More specifically, the invention is concerned with the connection of an underwater well having a submerged wellhead to an accessible location.
- the present invention may be briefly described as a method for connecting an underwater well having a submerged Wellhead to an accessible location in which a first fluid passageway is provided from a point adjacent to the wellhead of the underwater well to a point intermediate to the wellhead and water surface.
- a second fluid passageway is provided from the intermediate point to a point at least at water surface or adjacent thereto.
- the lower end of the first fluid passageway is connected to the wellhead by means of a movable connection and the upper end of the first fluid passageway is movably connected to the lower end of the second fluid passageway.
- the other end of the second fluid passageway terminates at an accessible location which may be a platform at, or above, the water surface.
- the wellhead may be on water bottom or may be located at a point above water bottom but below water surface, such as on a submerged platform or other structure below water surface.
- the present invention is also concerned with apparatus for connecting an underwater well having a submerged wellhead to an accessible location which may be at or above water surface which comprises a first flow line extending from a point adjacent to the submerged wellhead to a point intermediate to the submerged wellhead and Water surface.
- a second flow line extends from the intermediate point to at least water surface and means are provided for movably connecting the lower end of the first flow line to the wellhead.
- Means are also provided for movably connecting the upper end of the first flow line to the lower end of the second flow line.
- the second flow line terminates at an accessible location which may be on a platform at, or above, water surface.
- the fluid passageway is suitably in a flow line extending from a point adjacent to the wellhead to an intermediate point between the wellhead and water surface.
- This member is maintained under tension suitably by providing buoyancy to the member.
- the second fluid passageway is provided in a second member which extends from the intermediate point to at least water surface, the second member may be maintained under compression by providing weight thereon, but maintenance of the second passageway under compression is not necessary.
- the first flow line is maintained under tension by connecting the upper end of the first flow line to a buoyant member.
- Tension members mooring lines
- Flow lines may be supported inside or outside of tubular tension members or outside of cables, chains, or rods.
- tension is provided by installing the flow lines in a sea drome platform which will be illustrated further.
- a combination of tension members and compression members is separated by a submarine float or ice underwater buoyancy means with the tension member being maintained under tension by the float or buoyancy means and the compression members being maintained under compression by weight such as a platform supported thereon.
- Supporting members between anchors and float are necessarily in tension.
- Supports between floats and deck will be in compression; however, flow lines may be in tension or compression depending on their attachment to the supporting members.
- the essence of this invention is to use the main tension members to support (internally or externally) the flow lines.
- Floating vessels have provided suitable foundations for conducting drilling operations in water depths of more than 350 feet, but these vessels lack characteristics necessary for the conducting of oil or gas field operations.
- floating vessels have been used for drilling oil and gas wells in an offshore area and then the wells so drilled have been completed with wellhead installations on the ocean floor with submarine flow lines extending to production facilities on the nearest coast. The cost of this type of installation increases rapidly as the distance from the wellhead to the coastline increases.
- hydrocarbon reservoirs may be explored and/ or drilled from a floating or bottom-supported mobile drilling rig.
- the wells may be plugged and abandoned or capped for re-entry at a later time or completed on the ocean floor for later remote control of production.
- a sea drome platform will be installed at a central location in the offshore hydrocarbon field prior to initiating development drilling operations.
- drilling may be from other types of platforms, a sea drome being moved in only for production operations as may be desired.
- the type of platform which may be used in the practice of the present invention obtains support through a combination of tension members and compression members separated by a submarine float or underwater buoyancy means. At least three tension members which are parallel and of equal p platform,
- the submarine float may be a single vessel or a combination of separate buoyancy means which supports a framework that reaches upwardly to an elevation above the water surface where a horizontal deck provides a working surface.
- Such a platform is described in US. Patent No. 3,154,039 issued Oct. 27, 1964 in the name of Richard P. Knapp.
- a drilling rig may be installed on the platform deck from which one or more submarine wells may be dnlled.
- a plurality of wells may be drilled from the floating platform.
- Wells may be drilled from other platforms or floating vessels.
- Satellite wells may be drilled by other platforms, before orafter installation of production platform.
- Wells directly below the production platform may be drilled by other rigs before installation of production as well as later from the production platform.
- flow lines from the underwater Christmas trees are installed on the tension members. The flow lines may be installed on tension members before wells are drilled, thus anticipating remote connection to the wellhead at a later time.
- flow lines are suitably carried externally or internally by the tension members up to the buoyancy members which support the flow line.
- a passageway through the buoyancy members connects to a second flow line which extends through or is carried by the compression members which support the platform on the buoyancy members.
- the first and second flow lines being carried respectively by the tension members and the compression members are suitably protected from butfeting by wave and sea current action.
- conventional production facilities may be installed on the platform deck and connected to the second flow line for storage of hydrocarbons. Tankers and barges may be loaded from the storage by suitable connections thereto. Production from several wells may also be connected to a large pipeline lea-ding to the coast, central storage at offshore location, or other tanker loading facility.
- the'invention may be employed for well connections which may extend a mile or more from the platform.
- a well may be drilled from the floating platform or some other platform or support, and then the floating platform or other support may be moved to another location and then serve as a production facility for several wells on a radius of a mile or more from the floating platform.
- the submerged wellhead may be above water bottom.
- the submerged wellhead may be arranged on a submerged platform or other support at depths below violent wave and current action.
- FIG. 1 is a view of the floating platform illustrating the connection to an adjacent submarine wellhead and to a remote wellhead while a third well is in the course of being drilled;
- FIG. 2 is a general view illustrating the slight lateral displacement of the floating platform during violent wave action.
- numeral 11 designates the deck of a floating platform generally indicated by the numeral 12.
- the floating platform 12 is provided with a plurality in excess of three floats or buoyant means 13 which support the platform or deck 11 by support members 14 which are suitably cross braced by structural members 15 and 16.
- the float may be a single unit, barge-like, a torus, a square torus, or other shape. However, three mooring lines (tension members) are necessary.
- the support members 14 extend from the buoyancy means 13 to the deck 11 and therefore are under compression.
- tension means .18 Connected movably to the buoyant means 13 such as by hinged connection 17 are tension means .18 which are connected by hinged connection 19 to an anchor 219 which may be buried in the water bottom 21 or which may be a separate member on the ocean floor. It will be noted that the deck 11 is at a distance substantially above water surface 22.
- first flow line 23 which extends to the buoyant means 13 and which is movably connected through the buoyant means 13 to a second flow line 24 which is carried internally or externally by the support member 14.
- the first flow line 23 communicates with the second flow line 24 by means of a passageway 25 formed in the buoyant means 13.
- the first and second flow lines 23 and 24 may be constructed or formed integrally with tension means 18 and support member 24, respectively.
- the first flow line 23 is connected movably to a wellhead 26 of a submarine well 27 which penetrates at least one hydrocarbon productive formation.
- the wellhead 26 is connected movably by connection means 28 to the flow line 23.
- tension means 18 may be provided with a first flow line 23a which is carried by the tension means 18 and which likewise extends to a buoyant means 13 and which is suitably connected by passageway 25 to a second flow line 24a, the upper end of which terminates on platform 11 as will be described further.
- Flow line 23a connects by a ground flow line 29 to a remote wellhead 30 on a submarine well 31 which had previously been drilled and which may be at a distance of a mile or more from the platform 12.
- a third well 32 provided with a wellhead 33 is being drilled through a drilling riser 34 from the deck 11 employing a drilling rig 35 thereon.
- the upper end of the second flow lines 24 and 24a may suitably terminate at and connect to oil and gas production and storage facilities on the deck 11 generally indicated by the numeral 36.
- the wellhead may suitably be lowered on top of the conductor pipe of a well and seated thereon by means of a guideline technique known to the art.
- the flow line 23 may be connected to the wellhead at the deck 11 using a suflicient amount of slack therein such that it may be lowered to water bottom 21.
- Other means may be used for connecting the wellhead 26 to the flow line 23 such as by remote guideline technique.
- the flow lines may be attached to the wellhead at the deck, they may also be attached to the wellhead by using well-known remote connectors at the underwater wellhead location.
- Underwater connection methods that may be employed include the setting of a guide base on the sea floor or above the sea floor for a single well under the floating platform.
- the well is drilled and completed; then using drilling guidelines and guidance means on the tension supports of the platform, the distance from the wellhead to the tension members is measured.
- A. flow line riser is fabricated of suitable length and height and the riser is run to the elevation of the wellhead using guidelines from the drilling and guidance means on the tension members. These may be connected to the wellhead with hydraulic devices available in the industry for making remote connections underwater.
- a multiple well guide base may be set in association with the platform anchor installation in known alignment with the platform anchor and the tension support members.
- This base provides spacing for several wells directly below the platform and may include means for anchoring flow lines from remote wells a mile or more distant from the platform location.
- Guide cables or other guidance devices may be employed to direct remote flow lines to the underwater anchor.
- Wellheads below the platform and flow lines from remote wells are in known alignment with tension members supporting the platform, thus permitting the use of remote hydraulic or mechanical connections to one or more flow lines supported by the tension members.
- Other means for connecting the wellhead to the flow line may include tubular guides inside or outside of the tension members which may have a generous radius at the lower end permitting the use of flexible internal cables to pull a flow line into the lower end of the tubular guide and on up the guide for connection at an accessible elevation.
- short lengths of high pressure flexible conduit may extend from the flow line to the wellhead or flow line anchor also permitting the use of commercially available remote connectors with guidelines to the wellhead flow line anchor or to the flow line.
- the water depths at which drilling operations take place allow the use of divers to make the connection between the wellhead and the flow line. It is contemplated that divers may be employed.
- Apparatus for connecting a submerged wellhead of an underwater well to a platform floating at least adjacent the water level and supported in the water by a plurality of buoyancy means arranged below water level and anchored to water bottom by tension members, the platform being connected to the buoyancy means by rigid compression members comprising:
- a second flow line extending from the buoyancy means along one of said compression members to the platform; the lower end of the first flow line being connected to the wellhead for lateral movement of the first flow line relative to the wellhead; and the upper end of the first flow line being connected to the lower end of the second flow line for lateral movement of the second flow line relative to the first flow line.
