Definitions

  • the present invention relates to the economically viable extraction of hydrocarbon reserves from a single sub-sea well.
  • WO-A 0047864 discloses a single well development structure having a base structure framework. One side of a housing for a wellhead is placed at one end of the framework and the framework is then extended from the other side of the wellhead housing. A conventional christmas tree is fixed to the top of the wellhead housing and a barrier module and a process module are connected to the framework by respective connector hubs. The process module can contain a separator.
  • the object of the invention is to overcome at least some of the above-mentioned problems and provide a means by which a single sub-sea well field can be economically developed.
  • a single well development system comprising a base structure, a wellhead completing a well, and a retrievable christmas tree module including a christmas tree and connecting means for connecting the christmas tree module to the wellhead so as to receive well fluid therefrom, characterized in that:
  • the christmas tree module is primarily supported by means of its connection to the wellhead.
  • the base structure and/or the christmas tree module may include supplementary support means for the christmas tree module which is independent of the wellhead connecting means.
  • the system indudes at least one fluid connector, the or each fluid connector comprising first and second engageable portions, the first portion forming part of said retrievable module and the second portion forming part of the base structure.
  • the engageable portions may each include plural passageways for separate fluid flows and may form part of the connecting means for connecting the christmas tree to the wellhead.
  • the retrievable christmas tree module may include a power and/or control pod.
  • the system indudes at least one electrical connector, the or each electrical connector comprising first and second interengageable portions, the first interengageable portion forming part of said retrievable module and the second interengageable portion forming part of the base structure.
  • the first interengageable portion is connected to the power and/or control pod in the module.
  • the base structure may comprise a drilling template for drilling a well.
  • the base structure may include means for guiding the retrievable module onto the base structure.
  • the base structure may have means for supporting the retrievable module.
  • the base structure based second engageable portion of the fluid connector may be connected to a flow line connection for conveying fluid from the base structure to one or more extemal flow lines.
  • connection means preferably also includes an electrical connector as described above.
  • the base structure second interengageable portions of the electrical connector may be connected to an integrated service umbilical for receipt by the system of electrical power and/or control signals, injection chemicals for addition to fluids acted on by the system etc.
  • Fluid processing means in the module may comprise one or more separators, such a gravity separators, hydrocyclones etc.
  • the flows through which may be controlled by means of flow control valves, preferably electrically actuated which may be adjusted under control of a power and/or control pod.
  • the invention also provides a method of exploiting the output from a single well, comprising the steps of:
  • the method may also include employing any of the features referred to above.
  • a first system according to the invention is shown in Figure 1.
  • a well string 2 emerges from the seabed 4 and terminates in a wellhead 6 Installed through a base structure 8 connected to the seabed 4.
  • a retrievable module 10 containing a christmas tree 12 connected to a wellhead connector 14 is mounted on the base structure 8 by means of the wellhead connector 14 being coupled to the wellhead 6 and possibly by other engagement means not shown.
  • the retrievable module 10 also includes fluid processing means 15 including a minimum of two separators 16 which substantially duplicate each other thus affording component redundancy.
  • the module could alternatively include only one set of processing means components.
  • an electrical connector 18 is provided having first and second complementary interengageable portions 20 and 22 constituting parts of the module 10 and the base structure 8 respectively.
  • An integrated service umbilical 24, for connection to a remote facility is connected to the second interengageable portion and a power and control pod 26 is connected to the first interengageable portion.
  • a fluid connector 28 including first and second complementary interengageable portions 30 and 32 constituting parts of the module 10 and the base structure 8 respectively.
  • the second portion 32 being connected by one or more outlet pipes 34 to a flow line connection 36 which is in turn connected to one or more flow lines 38.
  • Isolation valves 40 are incorporated in piping runs leading to the fluid connector 28 which can be closed when its first and second engageable portions are to be separated.
  • Fluid output from the christmas tree 12 to each separator 16 via separator input pipe 44 is controlled by two failsafe valves 42 and a choke valve 46.
  • a gas output pipe 48 from each separator 16 routes gas through a pressure control valve 52.
  • the gas output pipes 48 communicate with a gas passageway 56 of the first portion 30 of the fluid connector 28.
  • a liquid output pipe 54 from each separator 16 routes liquid therefrom to a pump 50 and flow control valve 53 to a liquid passageway 58 in the first portion 30 of the fluid connector 28.
  • Electrical signals from various sensors are routed to the pod 26 which provides electrical signals for controlling the valves, the pumps, etc to control the operation of fluid processing means 15 and in particular the level of the gas/liquid interfaces in the separators 16. Signal/power lines between the components and the pod 26 have been omitted for the sake of clarity.
  • Figure 2 shows a second system according to the invention in which only one separator 16 is provided in the christmas tree module 60 rather than two.
  • Liquid 62, gas 64, the liquid/gas interface 66 and interface level sensor 68 are shown in the separator 16 in Figure 2. These features have been omitted from Figure 1.
  • Figure 3 shows a third system according to the invention which differs from that shown in Figure 2 in that the fluid connector 28 and wellhead connector 14 of Figure 2 are replaced by a combined fluid connector and wellhead connector 70 including a first part 72 and a second part 74 comprising parts of the christmas tree module 76 and the base structure 78 respectively.
  • a combined connector 70 could be employed in the system shown in Figure 1.
  • the modules may form part of the modular system designed by Alpha Thames Limited of Essex, United Kingdom and named AlphaPRIME.
