Description
- This application claims priority to Brazilian Application No. PI0404603-0, filed Oct. 22, 2004, entitled “SISTEMA DE INJEÃO DE ÁGUA CAPTADA EM AQUIFERO SUBTERRÂNEO E POOS INJETORES EM RESERVATÓRIO DE ÓLEO,” and incorporates the same herein by reference in its entirety. This application also is a Continuation-In-Part of prior U.S. application Ser. No. 11/256,361, which was filed on Oct. 21, 2005, and incorporates the same herein by reference in its entirety.
- The present invention relates to a system for collecting and injecting water from a subterranean aquifer into hydrocarbon reservoirs and, more specifically, a system of water collecting wells in subterranean aquifers and of injection wells in hydrocarbon producing reservoirs, wherein one or more pumps may be utilized to improve injection rate. The invention is applicable in hydrocarbon production systems, where water injection is utilized to maintain hydrocarbon producing reservoir pressure, thereby enhancing recovery of the same.
- One of the principal methods of secondary recovery, known and employed in the field of hydrocarbon reservoir, especially in subsea petroleum, utilizes water injection to maintain the pressure in hydrocarbon producing reservoirs.
- Typically this water is collected and treated directly from the sea and/or from water produced jointly with the hydrocarbons.
- U.S. Pat. No. 6,149,458 teaches the installation of a Submersible Centrifugal Pump (SCP) within a dummy well for injecting water into injection wells. However, the system has the following deficiencies: it requires the construction of a shallow well for installation of the pump and a water treatment unit is required to treat the water to be injected, which has been collected from the sea and/or produced jointly with the hydrocarbons.
- In Petrobras' Brazilian Patent application PI 0400926-6 a method of installing a pump in a dummy well, in this case an oil production well, is also disclosed.
- The principal deficiencies in the current state of the art include the high cost of treating the collected water, as well as the reliability of the quality of the water being treated and injected into the well. In addition, the method utilized for collecting and injecting water results in the injected water having a temperature which approximates that of the low temperature water found at the ocean floor.
- For hydrocarbons, in general, and especially for heavy oils, it is highly desirable and advantageous that the water be injected at a temperature which is higher than that found at the ocean floor. Water, injected under these conditions, facilitates the dislodgement and scouring of the reservoir. Another difficulty in the current state of the art is the installation of a water injection pump.
- Some existing models of compact pumps may be installed on the ocean floor in skids or may be integrated into a wellhead. However, utilizing submersible centrifugal pumps has certain advantages. Notably, submersible centrifugal pumps are produced on a large scale and at a low cost. Furthermore, submersible centrifugal pumps possess a slender geometry which requires the drilling and construction of dummy wells for accommodating the same, as described in the patents above.
- The disadvantages in the state of art discussed above are remedied by using an injection system which utilizes water collected from subterranean aquifers.
- More specifically, present invention presents a system of water collecting wells in aquifers and injection wells in hydrocarbon producing reservoirs which provides a means of maintaining pressure in the reservoirs by injecting water, of higher quality and at a higher temperature, thereby dispensing with a water treatment unit and reducing the costs of installation and operation of stationary units in subsea petroleum production fields.
- In this way, it is possible to maintain hydrocarbon producing reservoir pressure by injecting water having a good quality and higher temperature than that presently achieved in the state of the art, thereby increasing productivity and the oil recovery factor of the reservoir.
- Another application of this invention is in mature fields where there is no space on existing platforms for the construction or enlargement of the existing water injection unit.
- Systems consistent with the invention enable water collection from subterranean aquifers and direct injection of that water into hydrocarbon producing reservoirs to maintain pressure in the reservoirs.
- The collection of water in subterranean aquifers is accomplished by means for collecting water, as a collecting well. This collected water may be pressurized by means of a submarine pump and thereafter injected through injection wells, whose points of destination are located at the base of the hydrocarbon producing reservoirs or in an active aquifer in the oil reservoir.
- The hydraulic connection that pumps water from a collecting zone in a well to a injection zone of a hydrocarbon reservoir may be accomplished in accordance with the following embodiments as illustrate the drawings:
- (1) a hydraulic connection on the seabed with underwater pipelines linking at least one collecting well with at least one injection well, a pump being installed on the seabed or on the collection well itself;
- (2) a hydraulic connection inside a single or multilateral well, with access to the collection zone and to the injection zone; and
- (3) a hydraulic connection outside of a single or multilateral well, with access to the collection zone and to the injection zone.
-
FIG. 1 illustrates a basic embodiment of the invention wherein a conventional collecting well is linked through submersible pipelines to one or more injection wells, and an injection pump is installed externally between the collecting well and the injection well on a metallic structural base, a dummy well or other adequate means. -
FIG. 2 illustrates another embodiment of the invention wherein at least two wells (a collecting well and an injector well) are externally linked. The injection pump is installed within the collecting well, thereby avoiding the need for installing a Wet Christmas Tree (WCT). -

-
Fig No. of Wells Type of well Pump location 1 >=2 Conventional Outside 2 >=2 Conventional Inside 3 1 Multilateral Inside 4 1 Multilateral Outside 5 1 Conventional Outside 6 1 Conventional Inside 7 1 Multilateral Outside - A system for collecting water from subterranean aquifers and injecting that water directly into hydrocarbon producing reservoirs is described in accordance with the following embodiments:
- (1) a hydraulic connection on the seabed with underwater pipelines linking at least one collecting well with at least one injection well, a pump being installed on the seabed or on the collection well itself;
- (2) a hydraulic connection inside a single or multilateral well, with access to the collection zone and to the injection zone; and
- (3) a hydraulic connection outside of a single or multilateral well, with access to the collection zone and to the injection zone.
- In the first embodiment (1), the hydraulic interface occurs at the ocean floor through underwater pipelines which link at least one collecting well with at least one injection well. Since this construction requires at least two independent wells, the collecting well and the injector well, production costs are increased compared to an embodiment with one well. In addition, the temperature of the water being injected is reduced, due to the substantial thermal exchange which occurs between the collected water and the sea water over the length of the submarine line which connects the wellheads of the wells (i.e., of the collection well and the injection well).
- The injection pump may be located outside of the wells, thereby permitting it to be removed and reinstalled by means of a cable from a low daily cost vessel. This solution presents greater flexibility in the spacing between the point of collection and the point of injection. In this embodiment the design of the wellhead, collection column and injection column are conventional.
- Alternatively, the pumping unit may be installed in the collecting well, without the need for a Wet Christmas tree (WCT).
- In the second embodiment (2) above, both the pumping unit and the hydraulic connection between the collecting well and the injection well are located inside a conventional or multilateral well which has access to the collecting and injection zones. This embodiment eliminates the need of two wells (for collecting and injecting) and maintains the injection water at a higher temperature by avoiding thermal exchange with sea water on the ocean floor, which is generally colder. In this case, with the injection pump being positioned inside the well, maintenance will require the use of a rig, with higher costs.
- In the third embodiment (3) above, the pumping unit and the hydraulic connection between the collecting well and the injector well are located outside a conventional or multilateral well, thereby facilitating the removal and reinstallation of the injection pump and hydraulic connection via cable from a low daily cost vessel. There is a substantial reduction in costs due to the need of only one well with dual functions, i.e., collecting and injecting water, as opposed to the need of two wells embodiment. Furthermore, the temperature of the water being injected is higher because there will be no substantial thermal exchange between the collected water on the ocean floor, which is generally much colder.
- Therefore, a system for direct injecting water, collected from a subterranean aquifer, into a hydrocarbon producing reservoir, comprises:
-
- means for collecting water from a subterranean aquifer;
- at least one well;
- an injection pump that pumps the collected water into the hydrocarbon producing reservoir through a injection well; and
- a direct hydraulic connection between a collecting zone of the subterranean aquifer and an injection zone of the oil reservoir, the hydraulic connection comprising at least one submersible pipe.
- In accordance with the following description, based on the drawings, the reference numbers are:
- 1. Collecting well
- 2. Injection well
- 3. Injection Pump
- 4. Directional or Horizontal (Conventional) well
- 5. Annular space
- 6. Multilateral well
- 7. Collection column
- 8. Injection column
- 9. Telescopic assembly (Tubing Seal Receptacle (TSR))
- 10. Obturator (Tubing Packer Hanger)
