Definitions
- the present invention relates to a sub sea processing system in connection with the production of oil and/or gas from one or more wells, especially wells producing heavy oil in deep water and with high viscosity.
- Sub-sea pipeline bundles are commonly known and represents enhanced pipeline systems for the transportation of oil and gas and remote operation of sub-sea oil and gas wells.
- Such bundles may include a carrier pipe (outer casing or shell), within which may be provided one or more flow-lines for oil and gas, pipeline(s) or other arrangement for heating as well as hydraulic and/or electric control lines for the remote operation of the wells.
- This bundle solution may provide highly efficient thermal insulation and /or active heating elements to minimize thermal losses.
- Bundle solutions are commonly used, among other situations, where operation takes place on deep water, where seabed areas are congested, where diverless operations are mandatory or where anchor patterns restrict available seabed.
- bundle solutions as such do not solve the challenges associated with well operations in deep water with low temperature and production of heavy oil with high viscosity, but may be included in the solutions designed for such situations.
- a sub sea processing system in connection with the production of oil and/or gas from one or more wells, especially wells producing heavy oil in deep water and with high viscosity.
- the system is designed to maintain preferred production temperature and is, in particular, designed to obtain required temperature conditions under start-up and shut-in.
- FIG. 1 shows a principal sketch or scheme of a processing system according to the invention
- Fig. 2 shows a principal sketch or scheme of an alternative processing system according to the invention.
- Fig. 1 shows, as stated above, a principal sketch or scheme of the processing system according to the invention.
- the system may include one or more production wells 1 for the production of oil and/or gas, one or more injection wells 2 for the injection of produced water, a flow control device 11 , a separator 3, a production pump 4, a water injection and circulation pump 5 and a heating arrangement 6.
- the heating arrangement may preferably be in the form of an electrical heating system however, depending on the environmental situation, e.g. the surrounding temperature, sufficient heat may be provided through the work (heat energy) generated by the circulation pump 5.
- the major feature of the invention is the provision of a water circulation and injection pipe loop 7 interconnecting the separator 3, the injection and circulation pump 5, the heating arrangement 6, the flow control device 11 and the wells 1 and 2.
- Water is initially added to the system through a water supply line 8 and is heated by the circulation pump and, if required, by the heating arrangement 6.
- the heated water is circulated by the circulation pump 5 to the injection well 2, further to the flow control device 11 and the production well 1 and thereafter to the separator 3, before finally being returned from the separator to the circulation pump 5.
- the heated water in the pipe loop system prevents wax and/or hydrates to deposit in the piping.
- the hot water gradually heats the well to the required start-up temperature to avoid that any wax or hydrates being present in the produced oil will be deposited in the well or production piping. Further, during start-up, produced well fluid will mix with the water in the loop and after a while, as production increases, reach steady state conditions.
- produced fluid in the form of oil/water and possible gas flows through the production and circulation pipeline 9 to the separator 3 where the major parts of the hydrocarbons (oil and possible gas) are separated from the water.
- the produced oil and possible gas being present in the fluid flow is transferred by means of the production pump 4 from the separator 3 to the desired destination 15 (a platform, production ship, trunk line, shore terminal etc.) via a production pipeline 12.
- the oil and gas may be transported individually from the separator in separate oil and gas pipelines 12 and 13 respectively.
- the produced water on the other hand is circulated from the separator 3 by the circulation pump 5 to the injection well 2 and/or to the flow control device 11. Further, based on the amount of produced water from the wells, additional injection water may be added to the circulation system through the water supply line 8 to maintain sufficient water for injection and to maintain the desired water cut conditions to obtain the best possible separation situation in the separator 3.
- a multiphase detection device 14 is provided prior to the separator 3 measuring the amount of water being present in the fluid flow ahead of the separator, whereby water is added to the system through the supply line 8, the flow control device 11 , or production/injection wellhead chokes adjusted accordingly based on these and other measurements. .
- any separator could be used to separate the water from the hydrocarbons in the system.
- a pipe separator may in some situations represent the desired choice due to separation performance and structural design.
- the vertical column 10 on the right hand side of the Figs. 1 and 2 indicate a riser bundle being connected to a production platform or ship etc. 15 and may include all required riser and supply lines such as the production lines 10, 13, the water supply line gas lift lines and electrical cables etc.
- the present invention as defined in the claims is not limited to the above examples and the attached figures.
- the system does not require the use of injection well(s) to handle produced water.
- the produced water could be handled by a disposal solution, for instance a disposal well.
- the injection and production wells may be arranged as individual wells, template wells or bundle integral wells.
- separator and pump station may constitute a separate modular installation or is integrated in the pipe-loop.
- water supply to the system may be supplied by means of a separate water producing well.
