Method and means for waterflooding a hydrocarbon fluid containing permeable formation below a body of water
The invention relates to a method of waterflooding a hydrocarbon fluid containing permeable formation below a body of water. The invention relates furthermore to means for carrying out such a method.
In hydrocarbon fluid recovery techniques it is well known to inject huge quantities of water (in the order of magnitude of thousands m3 per day) via an injection well into a subterranean formation for waterflooding the formation. By such waterflooding operation the hydrocarbon fluids in a formation are displaced towards a production well for recovery purposes. When waterflooding is applied in formations located below the seabottom, seawater is used as displacing fluid, which seawater is filtered to remove those particles therefrom that would clog the permeable formation and/or the injection well if the seawater would be injected into the formation without a preceding filtering action. Examples of particles which will clog the formation or the well are plankton, algae and inorganic matter such as clay and silt.
In view of the need of huge quantities of filtered seawater for waterflooding purposes, a large filter area will be required to remove these undesired particles from the seawater. Moreover, since the filter means of the known filters have frequently to be cleaned, spare filters will be required for permitting an uninterrupted filtering and waterflooding operation. Arrangement of filters for the above-mentioned purpose on offshore platforms is costly, since space and load capacity of platforms are restricted and extension thereof is expensive. The application of filters on the seabottom, where space is not a problem, is also costly in view of the expensive underwater cleaning operations, which have to be carried out frequently.
The object of the invention is to overcome the above-mentioned disadvantages of the currently applied filtering techniques.
To this end the method according to the invention of waterflooding a hydrocarbon fluid containing permeable formation located below a body of water wherein water is pumped from the body of water into the formation via an injection well extending between the formation and a level above the bottom of the body of water, which bottom at least locally has a permeable sandy top layer, includes the step of passing water for filtering purposes from the body of water through at least part of the pore space of the permeable sandy top layer to the submerged inlet of a conduit system leading to the injection well.
According to the invention the means for carrying out the above-mentioned method comprises an injection well extending between a hydrocarbon fluid containing permeable formation located below a body of water and a level above the bottom of the body of water which bottom at least locally has a permeable sandy top layer, and a conduit system with a submerged inlet and including a pumping unit for pumping water from the body of water via the pore space of the permeable sandy top layer into the injection well.
The invention will now be described by way of example in more detail with reference to the accompanying drawings, wherein
Figure 1 schematically shows a vertical cross section of a first embodiment of the invention;
Figure 2 shows a top view of the vessel shown in Figure 1 on a larger scale;

Figure 7 schematically shows a top view of a combination of vessels for use in the method according to the invention.
It will be appreciated that identical elements shown in the drawings are indicated by identical reference numbers.
Figure 1 shows a hydrocarbon fluid containing permeable formation 1 located below a body of water 2. An injection well 3 extends between a level above the bottom 4 of the body of water 2 and the formation 1. The upper end of the injection well 3 is provided with a wellhead 5. At the location of the injection well 3 the bottom 4 has a permeable top layer 6 substantially consisting of sand particles. A vessel 7 with an open bottom end 8 is arranged on the top layer 6 in the manner as shown in the drawing. An outlet 9 on the vessel 7 communicates with wellhead 5 via a pumping unit 10 and a conduit 11.
By activating pumping unit 10, water from the body of water 2 is passed via top layer 6 into the vessel 7 through the open lower end 8 thereof (see the arrows in Figure 1). As will be explained below with reference to Figures 2 and 3, the water is filtered by the top layer 6. From the interior of the vessel 7, a continuous flow of filtered water is pumped via outlet 9, conduit 11 and wellhead 5 into the injection well 3. The water flowing from the injection well 3 into the formation 1 will displace the hydrocarbon fluids in said formation towards a not shown production well, through which the hydrocarbon fluids are recovered.
Optionally, a separate high pressure pump may be applied for pumping the water from conduit 11 via the injection well 3 into the formation 1.
As shown in Figures 2 and 3, vessel 7 is formed by a circle-cylindrical side wall 12 and a curved top wall 13. Side wall 12 and top wall 13 may be of any suitable material, such as steel or reinforced concrete. Pumping unit 10 is supported by a framework 21 arranged on top of the vessel 7. The vessel 7 is furthermore provided with an annular supporting member 14 supporting the vessel in such a manner that part of the side wall 12 extends into the top layer 6. The annular supporting member 14 is secured to side wall 12 by means of a number of web plates 15. The side wall 12 and top wall 13 of the vessel 7 together with the upper surface of that part of top layer 6 that is located within the vessel 7 form an enclosed space 1 6.
The lower end of side wall 12 is provided with a tube 17 having a plurality of jet nozzles 18, through which water under pressure may be supplied to the top layer 6 for installing the vessel 7, as will be described hereinafter in more detail.
The method for filtering the water by means of top layer 6 and vessel 7 will now be explained with reference to Figure 3.
As described already hereinabove with reference to Figure 1, water is passed by the action of pump 10 from the body of water 2 into the top layer 6, and subsequently from the top layer 6 into the enclosed space 1 6 of the vessel 7.
This flow of water is indicated by arrows in
Figure 3. The water on entering the pore space of the sandy top layer 6 will be filtered and solids and other impurities that are suspended in the water will be caught in the pore space of the top layer as well as on the entrances to said pore space. The solids and other impurities even form a lowpermeable layer on top of the top layer, which low-permeable layer will filter the finest particles suspended in the water flowing from the body of water 2 in the direction of the arrows.
The depth to which side wall 12 extends into the top layer 6 is such that the water entering the vessel 7 through the open lower end 8 thereof contains hardly any solid impurities. Generally, a depth of 0.5 metre will be sufficient for the purpose, whereas a depth over 1.5 metre will show hardly any improvement of the filter action.
Depths over 0.5 metre will be advisable if scouring occurs of the area of the sand layer 6 that is situated around the vessel.
Water flowing from top layer 6 into the enclosed space 1 6 may have a sufficiently low velocity such that no sand particles from the top layer 6 will be entrained by the water. The horizontal cross-sectional area of the enclosed space 1 6 near the top layer 6 is then chosen dependent on the required throughput of filtered water and the characteristics of the top layer 6, such as the permeability, the weight and the size of the individual sand particles. To assure a sufficiently low velocity of the water over the total horizontal cross-sectional area of the enclosed space 1 6 near the top layer 6, the distance between the outlet 9 and the upper surface of the top layer 6 inside the vessel should not be too small. A distance of 0.5 metre may already be sufficient for the purpose.
If high velocities of the water upon entering into the enclosed space 1 6 are allowed, a filter screen having perforations of a size preventing the passage of sand particles from the top layer 6 therethrough should be arranged between the top layer 6 and the outlet 9. Such screen may consist of a filter mounted in the enclosed space 1 6 and on the entrance to the outlet 9 that communicates with the pump 10. An alternative filter screen will be described hereinafter with reference to Figures 5 and 6.
Vessel 7 may be installed in top layer 6 in various manners. In one of these manners, water under pressure is supplied via conduit 1 9 and the jet nozzles 1 8 in conduit 1 7 to the sandy top layer 6 after the vessel 7 provided with pumping unit 10t has been lowered onto the top layer 6. The water jets from the nozzles 1 8 form an annular hole in the top layer 6, in which hole the vessel 7 is allowed to sink until the annular supporting member 14 contacts the upper surface of the top layer 6. Once the vessel 7 has been installed, conduit 11 is arranged between pumping unit 10 and the wellhead 5.
Another manner of installing vessel 7 includes fluidization of part of top layer 6 by supplyiny water at a low velocity to the layer 6 and allowing the vessel 7 to sink into the fluidized part of top layer 6. In clayey bottoms, however, the use of jets is to be preferred.
Reference is now made to Figure 4 which shows a second embodiment of the invention. In this second embodiment an injection well 21 provided with a wellhead 22 extends between the formation 1 and an offshore platform 23, which platform is supported by a plurality of legs 24 extending into the bottom 4 of the body of water 2. A vessel 25 having an open bottom end 26 is arranged in the sandy top layer 6 in the manner as shown. Details of the vessel 25 will be discussed hereinafter with reference to Figures 5 and 6.
Between the vessel 25 and the offshore platform 23 a conduit 27 is arranged, which conduit is secured to one of the legs 24 by means of not shown clamps.
For pumping water in an upward direction through conduit 27 a gas-lift action is applied, which action is brought forward by a gas injection system. This gas injection system comprises a compressor 28 arranged on the offshore platform 23 and a conduit 29 extending between the compressor 28 and the interior of the conduit 27 via an inlet nozzle (not shown) situated in the lower vertical part of the conduit 27. The upper end of conduit 27 is connected to a gas/liquid separator 30 arranged on the offshore platform 23. A conduit 31, provided with a pumping unit 32, forms a fluid communication between the wellhead 22 and the separator 30, whereas a conduit 33 forms a fluid communication between the compressor 28 and the upper part of the separator 30.
Compressor 28 is operated to pump gas through conduit 29 and into the lower vertical part of conduit 27. The gas bubbles in the conduit 27 cause lifting of the water in said conduit, with the result that water will be induced to flow from the body of water 2 through top layer 6 into the vessel 25 via the open lower end 26 thereof and from there through conduit 27 towards the separator 30. Top layer 6 in combination with the vessel 25 filters the water in the same manner as described in the above with reference to Figures 1,2 and 3.
In the separator 30 the gas is separated from the filtered water, after which the gas is recirculated to the compressor 28 via the conduit 33 and the water is pumped by pumping unit 32 via conduit 31 and the injection well 21 into the formation 1 for displacing the hydrocarbon fluids present in said formation.
It will be appreciated that any gas may be used in the above-described gas injection system.
Some gases, such as nitrogen and natural gas have the advantage that, when they are applied in the gas injection system, dissolved oxygen present in the water will be driven out, resulting in a considerable reduction of the size of the facilities for oxygen removal required for restricting corrosion of the injection system. The application of natural gas in the gas injection system has a further advantage in that this gas is obtained during recovery of the hydrocarbon fluids and therefore easily available.
Reference is now made to Figures 5 and 6, showing details of the vessel 25. Vessel 25 having a rectangular horizontal cross section is formed by closed side walls 34 and a closed top wall 35. An outlet 36, arranged in the upper part of one of the side walls 34 forms a fluid communication between the interior of the vessel 25 and the conduit 27 (see Figure 4). An enclosed space 37 for collecting filtered water is formed by the top wall 35, the side walls 34 and the upper surface of that part of the sandy top layer 6 that is located within the vessel 25.
For supporting the vessel 25 in the sandy top layer 6 an open framework 38 at the lower end thereof provided with a perforated screen 39 is arranged in the interior of the vessel 25. The screen 39 may be secured to the framework 38 in any suitable manner, such as by welding. The size of the perforations of the screen 39 may be such that sand particles from the top layer 6 cannot pass the screen 39, as a result whereof the water may enter the enclosed space 37 at a relatively high velocity without the risk of entraining sand particles into said space.
The vessel 25 may be installed by lowering the vessel onto the top layer 6. A (not shown) flexible conduit communicating with a (not shown) pumping unit carried by a (not shown) working boat is used for sucking water from the enclosed space 37. The pressure difference created thereby across the top wall 35 of the vessel 25 forces the vessel 25 to sink into top layer 6, until the supporting framework 38, 39 contacts the upper side of the top layer 6. In this position the flexible conduit is uncoupled and replaced by conduit 27 which conduit is adapted for the transport of filtered water as discussed in the above.
Reference is now made to Figure 7 showing a top view of an arrangement of a plurality of vessels for use in the method according to the invention. In the shown arrangement three vessels 40,40', 40" (which may be of the type as shown in Figure 3) are installed in top layer 6.
The interior of each of the vessels 40, 40' and 40" is connected by means of a conduit 41, 41'
and 41, respectively, to the interior of a collecting
tank 42, provided with an outlet 43 and a
pumping unit 44. Pumping unit 44 is applied for
passing water from the body of water into each of
the vessels 40, 40', 40" via filtering top layer 6
and from these vessels through conduits 41, 41' and 41" into the collecting tank 42. From the
collecting tank 42 the water may be pumped via a
conduit 45 towards one or more injection wells for water-flooding purposes.
The vessels 40, 40' and 40" are so arranged
relatively to each other that each of the vessels
produces an optimal quantity of filtered water. To ) this end the distance A is at least 10 times the
diameter D of the vessels 40, 40' and 40".
It will be appreciated that the vessels and the
collecting tank may be interconnected by means
of a suitable framework (not shown), allowing an
easy installation procedure for the whole
arrangement.
Application of the invention is not restricted to
a particular waterflooding technique. Instead of a
single injection well, a plurality of injection wells may may be used, which wells may be arranged in any desirable pattern. Before injecting the filtered
water into the formation, the water may be further
treated as known per se in a water-treating plant
installed on the bottom of the body of water or on
the offshore platform.
It is observed that the water from the body of
water may be filtered over long periods without
requiring dispiacement of the vessel 7, 25 to a
fresh part of the sandy top layer 6. In the majority
of cases, the sandy top layer is regularly refreshed
by water currents sufficiently strong for removing
most of the impurities deposited on the top layer,
thereby preventing plugging thereof. In case the
water currents are insufficiently strong and
plugging of the top layer in the immediate
surrounding of the vessel would occur, the water
from the body of water will enter non-plugged
areas of the sandy top layer further away from the
vessel and will subsequently flow to the vessel
along a substantially horizontal path in the top
layer.The same flow pattern of the water will
occur when the area of the sandy top layer in the
immediate surrounding of the vessel would be
covered by a natural deposit forming an
impermeable layer, such as a layer of clay.
If bottom 4 of the body of water 2 does not
have a sandy top layer 6, such top layer may be
artificially formed by depositing sand on the
bottom. Such an artificially formed sandy top layer
may be ballasted by coarse material, such as
gravel to avoid displacement of the sandy top
layer by water currents.
Furthermore, the invention is not restricted to a
special shape of the closed side walls and the top
wall of the open bottom-ended vessels.
Finally, it is observed that the vessels 7 and 25,
respectively, may partly or totally be filled with
coarse granular material, serving as a barrier for
the sand particles of the top layer 6 and/or as a
support for the vessel. Also, the vessel 7 may be placed in the top layer over the total height thereof. A filter screen should then be mounted on the entrance to the outlet 9. Also, such screen may be mounted in the outlet 9 in a manner such that it can easily be replaced by divers, if need arises. In still another manner, the screen may be of cylindrical shape and be placed on a pipe section that extends vertically downwards from the outlet 9. In placing the vessel, means should then be provided for jetting or fluidizing that part of the sandy top layer 6 through which the filter and the pipe section should protrude. If desired, the pipe section and filter screen may extend to a level below the lower edge of the side wall(s) of the vessel.
In all embodiments described, the vessel forms a firm anchor to the sea bottom for the inlet to the conduit system. Moreover, scouring of the area around the vessel will not result in a direct communication between the body of water and the entrance to the conduit system, thus preventing unfiltered water from entering the conduit system.
