Description
DEWATERING, TEST PUMPING AND DOWNHOLE MONITORING SYSTEM
2019100328 29 Mar 2019
Technical Field [0001] The present invention in one aspect, generally relates to a dewatering, test pumping and downhole monitoring system for a site at an exploration or mining lease.
Background Art [0002] Dewatering test pumping and downhole monitoring at sites at an exploration or mine lease conventionally uses a number of techniques. One involves the use of lengths of stiff pipes. Stiff pipes are typically supplied in short individual lengths that require coupling together at site for the dewatering and test pumping aspects. For downhole monitoring a separate line with the desired monitoring equipment is lowered into the site. This can require the use of a number of lines to pump and monitor different features relevant to the site.
[0003] The short individual lengths of pipe are transported to the bore site and are then lifted into position (often by crane) and connected together for lowering into the site. This requires multiple pieces of equipment such as trucks and cranes in addition to several technicians. There can also be the need of safety personnel to ensure that risks are mitigated.
[0004] Another common technique involves using layflat reeled pipe. As the reeled section of the layflat pipe is not expanded into a circular shape, layflat reeled pipes are required to be fully unwound to allow pumping. When the full length of the layflat pipe does not closely match the required length for the pumping operation excessive unreeling and layflat pipe length is required. Leaving the excess layflat pipe on the reel causes problems when fluid is attempted to be pumped. As the reeled layflat pipe is inflated it can damage the reel and the pipe.
[0005] Reeled, non-collapsible pipes for downhole pumping are known as in the invention described in PCT Application No. PCT/AU2013/001502. The reeled pipe of this invention comprises of multiple pipes entwined together. This allows high volume and flow pumping without the limitations requiring thicker walls for pumping at the same volumes and flow with a single pipe. These entwined pipes are cumbersome and not perfectly suited for applications where less flow rate and volume is required. It also
2019100328 29 Mar 2019 requires further technical steps of twisting and entwining pipes together to enable the creation of the pipes of PCT/AU2013/001502 which requires extra labour and cost. It also results in using a longer length of pipe than if a single pipe were used. Additionally, the pipes of PCT/AU2013/001502 allow pumping and sensing, but do not provide further monitoring capabilities.
[0006] Existing forms of this type of pumping use combinations of pumping capabilities along with basic sensors built into the pumping line. Where additional monitoring or data transfer capabilities are required additional lines are conventionally laid down.
[0007] The preceding discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.
Summary of the Invention [0008] It is an object of this invention to ameliorate, mitigate or overcome, at least one disadvantage of the prior art, or which will at least provide the public with a practical choice.
[0009] In a first aspect, the present invention provides mobile dewatering, test pumping and monitoring assembly including:
a pre-bundled flexible pipe that pumps fluid from and monitors a site at an exploration or mining lease;
a rotatably mounted reel arranged to receive the pre-bundled flexible pipe on the reel;
a submersible pump for pumping fluid through the flexible pipe; and a driving means to lower and raise the flexible pipe relative to the site;
wherein the pre-bundled pipe forms a single umbilical line; and wherein the pre-bundled flexible pipe is to be wound onto the reel and off the reel repeatedly.
[0010] Preferably, the pre-bundled flexible pipe includes a combination of a flexible fluid pipe, an electrical power cable to power the submersible pump, fibre optics cables and data transfer cables. This allows, pumping, sensing and other monitoring operations to be conducted using a single umbilical line.
2019100328 29 Mar 2019 [0011] Preferably, the pre-bundled flexible pipe includes features selected from:
a variable speed pump line;
a variable speed generator;
a power line;
a Mag Flow Meter;
an inline water quality unit;
a data cable;
PLC control lines; and a telemetry unit.
[0012] Preferably, the mobile dewatering, test pumping and monitoring assembly system is located on a single platform that is arranged to be transported by a carrier vehicle for driving on land.
[0013] Preferably, the mobile dewatering, test pumping and monitoring assembly is operated remotely.
[0014] In a second aspect, the present invention provides a method of dewatering, test pumping and monitoring water in a site at an exploration or mining lease, the method comprising:
positioning a mobile dewatering, test pumping and monitoring assembly, including a pre-bundled flexible pipe arranged so that the pre-bundled flexible pipe may be unreeled from the mobile dewatering assembly;
activating a drive means to cause the pre-bundled flexible pipe to be lowered into the site;
activating a pump at the distal end of the non-twisted, non-collapsible pipe to pump fluid from the site; and activating the monitoring assembly to take readings from the area at the site.
[0015] Preferably, the pre-bundled flexible pipe is adapted to be wound onto a reel and the reel is adapted to be transported on a carrier vehicle.
[0016] The reeling of the pipe and its transportability increase the ease with which the conduit can be used in different locations for different applications.
[0017] In not being collapsible, the life span of the pipe is increased.
2019100328 29 Mar 2019 [0018] To unreel the pipe, the reel may have a raised installation position.
[0019] A motorized driving device may be used to wind and unwind the pipe.
[0020] The installation and operating conditions may be the same position.
[0021] Preferably, the method is performed from a transportable platform. This enables the assembly to be moved between different sites where the method can be applied. By performing the method on a transportable platform, the assembly can be transported to the site, deployed and brought into operation quickly with minimal supervision.
[0022] The transportable platform may be the tray of a truck. This enables the assembly to be moved between sites using a truck.

Description of Embodiments of the Invention [0025] Broadly, the present invention provides a pre-bundled, single umbilical mobile dewatering, test pumping and monitoring assembly 9 arranged to transport pre-bundled flexible pipe 11 as a single umbilical, on a single reel, to, from and within exploration and mining leases for the purpose of dewatering, test pumping and geotechnical monitoring. At the mining lease, the mobile dewatering, test pumping and monitoring assembly 9 is arranged to be lowered to a desired depth in the mining lease without need to unreel the entire length of the single umbilical. The pre-bundled flexible pipe 11 includes a selection of flexible pipe 32, an electrical power line 36 and controlling/monitoring cables 34. The controlling/monitoring cables can consist of a downhole sensor, fibre optics cables, data communications lines, PLC control lines or any known cable required for controlling or monitoring downhole or on surface equipment or data gathering devices for controlling monitoring devices in the pre-bundled flexible pipe 11. The controlling or monitoring devices can include a variable speed pump, a variable speed generator, a Mag Flow Meter, inline water quality unit and a telemetry unit. The multiple lines are joined together in a single umbilical line 30 to provide the capabilities to pump, sense, monitor and communicate monitored and sensed parameters in a single umbilical line.
[0026] The pre-bundled flexible pipe 11 may include one or multiple flexible pipes 32 for fluid transportation.
[0027] Having the above noted monitoring cables and devices in the pre-bundled flexible pipe 11 allows real time remote operation of the mobile dewatering, test pumping and monitoring assembly 9. It also removes the need for in field equipment adjustment. This improves the efficiency of pumping and monitoring. The monitoring devices allow for real time assessment of pump performance, flow rate, water quality and assessment, and downhole geotechnical parameters. This allows for the use of mobile dewatering, test pumping and monitoring assembly 9 for at least Borehole Yield Testing, Injection Bore Rehabilitation, Well Development, Dewatering and specialised hydrogeological project services using a single umbilical line and single reel.
[0028] Using a single umbilical line and reel allows remote operation, reduces the need for people to be present and at risk, minimises manual handling, allows for rapid deployment and use of the assembly, allows for the assembly on a single platform,
2019100328 29 Mar 2019 allows multiple depth level pumping from a single assembly and allows for standby loggers to be embedded along the length of the pipe for test readings.
[0029] The first embodiment of the present invention depicted in Figures 1 and 2 provides a mobile dewatering, test pumping and monitoring assembly 9. The assembly 9 includes a reel 10 with a receiving channel 17 for receiving the pre-bundled flexible pipe 11. The assembly 9 also includes a driving means 12 a land carrier vehicle 14 and a platform 16. The carrier vehicle 14 is a truck in the figures.
[0030] The non-collapsible pre-bundled flexible pipe 11 is to be wound onto reel 10 in channel 17. As it is non-collapsible, the pipe 11 retains its profile when wound on the reel. The non-collapsible pre-bundled flexible pipe 11 of the present invention is capable of being repeatedly wound onto and off a reel. A pump is placed on the distal end of the non-collapsible pre-bundled flexible pipe 11 that is to be lowered into the pumping site to pump water through the fluid passageway of the non-collapsible pre-bundled flexible pipe 11 for dewatering.
[0031] In one embodiment the non-collapsible pre-bundled flexible pipe 11 is a High Density Poly-Ethylene (HDPE) pipe. Alternatives materials for the flexible pipe, suitable for winding onto and from a reel, as would be understood by the skilled addressee can be used.
[0032] In one embodiment the drive means 12 is a generator that provides rotational motion to the spindle 18 that rotates the reel 10. The skilled addressee will recognise that alternative drive means can be used to rotate the spindle as understood by the skilled addressee.
[0033] As the non-collapsible pre-bundled flexible pipe 11 includes the power and monitoring cables they act a single umbilical line that can be wound from the reel 10 with ease without different lines becoming tangled or separated. The non-collapsible pre-bundled flexible pipe 11 is encased in a sleeve 30 to form the single umbilical line. In alternative embodiments, shrink wrap or ties may be used to pre-bundle the multiple elements. Alternative means to form a single umbilical fall within the scope of the present invention. These include using spiral guarding to pre-bundle the umbilical.
[0034] The first embodiment places the mobile dewatering, test pumping and monitoring assembly 9 on the tray platform 16 of a truck 14 to make the mobile
2019100328 29 Mar 2019 dewatering, test pumping and monitoring assembly 9 mobile. The truck 14 is driven to a site that needs to be dewatered, test pumped or monitored and places the mobile dewatering, test pumping and monitoring assembly 9 near the intended access point to the site. The reel 10 is powered and the pre-bundled flexible pipe 11 is lowered into the site until the pump at the end of the pre-bundled flexible pipe is lowered appropriately into the site to allow pumping to dewater, test or monitor the site. The pump is started and water flows through the pre-bundled flexible pipe to dewater, test or monitor the relevant area in the site.
[0035] Figure 3 illustrates a second embodiment of the present invention. In this embodiment the mobile dewatering, test pumping and monitoring assembly 9 is located on a trailer 26. The assembly 9 includes a reel 20 with a receiving channel 23. The assembly 9 also includes a driving means 22 on the trailer 26. The trailer 26 is arranged to be towed by a vehicle and is attached to the vehicle at connection means 27 as understood by the skilled addressee.
[0036] A pre-bundled flexible pipe 11 is to be wound onto reel 20 in channel 23. As it is non-collapsible, the pipe retains its profile when wound on the reel. The pre-bundled flexible pipe 11 of the present invention is capable of being repeatedly wound onto and off a reel. A pump and monitoring equipment is placed on the distal end of the pre-bundled flexible pipe 11 that is to be lowered into the site to pump water through the pipe and for monitoring conditions in the site.
[0037] In one embodiment the pre-bundled flexible pipe 11 is a High Density Poly-Ethylene (HDPE) pipe. Alternatives materials for the flexible pipe, suitable for winding onto and from a reel without collapsing, as would be understood by the skilled addressee can be used.
[0038] In one embodiment the drive means 22 is a generator that provides rotational motion to the spindle 28 that rotates the reel 20. The skilled addressee will recognise that alternative drive means can be used to rotate the spindle as understood by the skilled addressee.
[0039] The second embodiment places the mobile dewatering, test pumping and monitoring assembly 9 on the trailer 26 and is towed by a vehicle to make the mobile dewatering, test pumping and monitoring assembly 9 mobile. The vehicle is driven to a pumping site at the exploration and/or mining lease that needs to be dewatered and
2019100328 29 Mar 2019 places the trailer 26 and mobile dewatering, test pumping and monitoring assembly 9 near the site. The trailer 26 can be left by the site to perform the dewatering, test pumping or monitoring independently of the vehicle. The reel 20 is powered and the pre-bundled flexible pipe 11 is lowered into the site until the pump and/or monitoring equipment at the end, or along the length of for monitoring equipment, of the pre-bundled flexible pipe 11 is lowered appropriately into the site to allow pumping or monitoring of the site. The pump is started and water flows through the non-twisted, non-collapsible pipe.
[0040] In an alternative embodiment of the present invention two side by side, parallel pipes can be connected together and reeled as described above to provide the pipe for pumping or monitoring.
[0041] In both the first and second embodiments the reel 10, 20 is arranged to directly unreel from the tray platform 16 or trailer 26 without needing to move the reel up and down. This avoids the need for motors, actuators and framing to raise and lower the reel 10, 20. . In one embodiment the reel is able to be moved from side to side. This can aid in the ease of spooling. This simplifies the operation of the mobile dewatering, test pumping and monitoring assembly 9.
[0042] The mobile dewatering, test pumping and monitoring assembly 9 can be skid mounted so that at the site of operation, the mobile dewatering, test pumping and monitoring assembly 9 can be lifted from a transportation vehicle such as the truck 14, or another vehicle and placed on a frame at the site for operation.
[0043] Once the truck 14 is correctly positioned (or once the mobile dewatering, test pumping and monitoring assembly 9 has been removed from the truck 14 or other vehicle and placed on a positioned frame) the operation of the motor to turn the reel 10, 20 and lower the pre-bundled pipe 11, and then to activate the pump or monitoring equipment can be switched on.
Variations and Modifications [0044] Modifications and variations such as would be apparent to the skilled addressee are considered to fall within the scope of the present invention. The present invention is not to be limited in scope by any of the specific embodiments described herein. These embodiments are intended for the purpose of exemplification only. Functionally
2019100328 29 Mar 2019 equivalent products, formulations and methods are clearly within the scope of the invention as described herein.
[0045] Reference to positional descriptions, such as lower and upper, are to be taken in context of the embodiments depicted in the figures, and are not to be taken as limiting the invention to the literal interpretation of the term but rather as would be understood by the skilled addressee.
[0046] Throughout this specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
