Definitions

  • Embodiments of the subject matter disclosed herein generally relate to downhole tools for well operations, and more specifically, to a wellbore setting tool that sets a plug at a desired depth into the well and then releases, at a desired time, a restriction element to close the plug.
  • Plugs are used to separate various sections of the well for perforating and/or fracturing purposes.
  • the plugs block the casing so that a fluid from cannot pass the plug.
  • the plugs need to be engineered to withstand a high pressure (thousands of psi) that is traditionally applied to the well, but also to be easily milled away after they have performed their duty.
  • a traditional plugging system 100 is shown in Figure 1 and includes a plug 120 that is carried with a setting tool 102 and placed in a well 1 10, which was drilled to a desired depth H relative to the surface 1 12.
  • Figure 1 shows the plug 120 already being set and detached from the setting tool 102.
  • a casing string 114 (or simply casing herein) for protecting the wellbore 1 16 has been installed and cemented in place.
  • the plug 120 needs to be set up in the well as shown in Figure 1 and also to be closed so that well fluids cannot pass the plug.
  • the typical process of connecting the casing 1 14 to the subterranean formation 1 18 may include the following steps: (1 ) setting the plug 120, which has a through passage 122 inside the well, (2) closing the passage 122 to block fluid flow through the plug, (3) increasing the pressure inside the casing, and (4) perforating the casing 1 14 with a perforating gun 126.
  • a controller 130 located at the surface 1 12, is used to control the various tools and/or the fluid’s pressure inside the wellbore 1 16.
  • a wireline tool 124 may be used to lower the setting tool 102, the plug 120, and the gun string 126.
  • the structure of the traditional setting tool 102 and plug 120 is illustrated in Figure 2.
  • the setting tool 102 has a power charge 202, which when ignited, makes a mandrel 204 to move relative to a sleeve 206 so that a rod 208 pulls a piston 210 toward the setting tool 102.
  • Plug 120 is disposed around the rod 208 and between the sleeve 206 and the piston 210, as shown in the figure. Under the opposite forces exerted by the piston 210 and the sleeve 206, a first part 212 of the plug 120 moves toward a second part 214 of the plug so that a slip portion 216 moves over the second part 214 and engages the casing (not shown in Figure 2).
  • the rod 208 breaks away from the plug 120 and the setting tool 102 is freed from the plug 120.
  • the plug 120 is set (i.e., the slip portion 216 has engaged the casing) and the setting tool 102 can be retrieved from the well.
  • a passage (not shown) through the plug 120 allows fluid communication between the part of the casing above the plug and the part of the casing below the plug.
  • T o close the plug for preparing the well for perforating and/or fracturing
  • the setting tool 102 needs to be taken out of the well, a ball is introduced into the well and pumped down until the ball sits into a seat 218 located at a proximal end of the plug 120.
  • the ball (not shown) closes the passage and the fluid pressure inside the well and above the plug 120 can be increased.
  • the operation of taking the setting tool outside the well and then pumping down the ball is time consuming and expensive.
  • the existing plugs although made from composite materials, still require a substantial amount of time to be milled out, when the need appears to remove them.
  • the setting tool 102 may be configured to have a sleeve 206 in which a ball 310 is positioned. As long as the sleeve 206 is attached to the plug 120, the ball 310 is trapped inside the sleeve. A shear ring 314 connects the sleeve 206 to the plug 120. After enough force is exerted by the setting tool 102, and the plug 120 is set, the shear ring 314 breaks and the setting tool 102 separates from the plug 120.
  • Sleeve 206 is configured to have a trap 302 for trapping the ball 310 when the well is flown back, as shown in Figure 3B. Note that the ball 310 has left the plug 120 and is flowing toward the trap 302. A catching mechanism 304 for the ball 310 is also located inside a chamber 312 defined by the sleeve 206. In this embodiment, because the ball 310 is carried inside the sleeve 206, there is no need to remove the setting tool in order to place the ball in its seating position in the plug. When the ball needs to be removed, the back flow is established inside the well so that the ball moves past the trap 302, inside the chamber 312. Once the ball has passed the trap 302, the ball cannot return to the plug 120.
  • the gun string 126 is moved upward to the desired location, and they are fired, creating perforations into the casing and formation.
  • the guns are moved up-hole and fired several times, each time, perforating the casing and the formation.
  • the expended guns are then removed from the well.
  • the well is now pressurized from the surface to a high enough pressure to fracture the formation. To accomplish this, the well has to be plugged. This is the function of the ball 310.
  • the ball 310 rolls from the sleeve 206 toward the plug 120 and then against the top of the plug 120 and makes a seal.
  • the ball 310 is being used as a check valve. It will allow fluid to move upward, but it will stop fluid from moving downward.
  • next string of guns, setting tool, ball, and plug is then lowered into the well for performing further perf and fracturing operations.
  • the reason it is possible to lower the next gun string into the well is because the fluid that is pumped into the well exits the newly created perforations.
  • the sequence repeats, and each of these sequences are called a stage. There could be many stages per well (e.g.,
  • the balls either dissolve, or a Coiled Tubing Run is used to mill them out and remove debris from the well.
  • mis-fire If not enough of the perforations are created in any of the stages, it is called a mis-fire.
  • the next string of guns or anything else cannot now be pumped down to its depth because the ball is preventing the fluid from being pumped into the well. Thus, the ball needs to be removed before the next string of guns can be pumped in.
  • the well pressure at the surface is dropped quickly. This causes the fluid to flow-back out of the well. This means that the fluid in the well flows in an upstream direction, which makes the ball 310 to enter the sleeve 206 and become trapped by the trap 302. Now the guns, setting tool and the ball are removed from the well and the next gun string is pumped in as the removal of the ball 310 from the plug 120 allows the fluid to be pumped into the well.
  • a setting tool for setting a plug in a well.
  • the setting tool includes a housing extending along a longitudinal axis X and having a bore, a sleeve extending along the longitudinal axis of the housing, and located within the bore of the housing, and a holding mechanism located within the sleeve and configured to hold a ball within the sleeve.
  • the holding mechanism is configured to release the ball upon receiving a signal.

  • a setting tool that holds a restriction element (e.g., a ball herein) and a plug that accepts the ball.
  • the setting tool is attached to the plug.
  • the setting tool sets the plug and then, it releases the ball to close the plug at a time that is decided by the operator of the plug. If a decision is made that the guns have failed to perforate or that the ball should not be released, the setting tool may be retrieved from the well while the ball is still locked inside the setting tool.
  • the ball is simply not released into the well although the plug has been set.
  • the ball is held inside the setting tool with a holding mechanism.
  • the holding mechanism may be implemented, as discussed next, as a mechanical device, an electronic device, or as a flexo-mechanical device.
  • a setting tool-plug system 400 that includes a novel setting tool 410 is now discussed with regard to Figure 4.
  • the setting tool 410 is shown in Figure 4 being attached to a plug 480 and both elements being placed in a casing 470 of a well.
  • the plug 480 may be any known plug.
  • Plug 480 is shown in the figure not being set, i.e., its sealing element 482 not touching the casing 470.
  • the plug 480 has an internal mandrel 484 that is attached with one or more shearing pins 486 to the setting tool 410. Note that a plug that does not have an internal mandrel may also be used with this novel setting tool.
  • the setting tool 410 includes a housing 420 and a sleeve 422 located within a bore 421 of the housing 420.
  • the housing 420 is configured to contact the plug 480 while the sleeve 422 is attached to the inner mandrel 484 of the plug, with the shearing pins 486.
  • the housing 420 When the setting tool is actuated, the housing 420 generates a reactionary force along the longitudinal axis X while the sleeve 422 is pulling the mandrel 484 along the opposite direction of the axis X, thus exerting a pulling force opposite to the reactionary force.
  • the mandrel 484 is biasing the sealing element 482 toward a member 486, which results in the sealing element expanding along a radial direction and eventually touching the casing 470, as illustrated in Figure 5. Note that after the plug 480 is set, the fluid inside the well cannst pass the plug only through its internal bore 488.
  • the setting tool 410 is shown having an internal holding mechanism 430, that is configured to hold the ball 432 inside the sleeve 422.
  • the internal holding mechanism 430 is implemented in this embodiment as a mechanical device and it is located entirely inside the sleeve 422. More specifically, the holding mechanism 430 includes a swinging arm 434 that is configured to rotate about a fixed point 436, that is attached to the sleeve 422. Thus, the swinging arm 434 could pivot about the fixed point 436. However, to prevent the swinging arm 434 to pivot toward the plug 480, a hitting stop 438 is formed into the sleeve 422.
  • the swinging arm 434 is prevented by the hitting stop 438 to pivot to the right in Figure 4, i.e., toward the plug 480. In this way, the ball 432 cannot exit the sleeve 422. However, the swinging arm 434 can pivot toward the ball (to the left in the figure).
  • the swinging arm 434 has a through hole 440 through which a pushing arm 442 extends, from one side of the swinging arm to the other.
  • the pushing arm 442 has a shoulder 444, located between the swinging arm 434 and an upstream end 410A of the setting tool 410.
  • a downstream end 410B of the setting tool is connected to the plug 480.
  • the terms“upstream” and“downstream” in this application refer to the head and toe of the well, respectively.
  • Shoulder 444 is configured to pass through the hole 440 of the swinging arm 434 when the pushing arm 442 is free to move along the positive direction of the longitudinal axis X.
  • the pushing arm 442 cannot move along the positive direction of the longitudinal axis X, and thus, the shoulder 444 remains on the upstream side of the swinging arm 434.
  • the hole 440 is selected at a given location along the swinging arm 434, so that an end 442A of the pushing arm 442 is facing and will contact the mandrel 484 of the plug 480. If the plug 480 has no mandrel, then the hole is selected so that the end 442A of the pushing arm 442 contacts a solid element of the plug.
  • Figure 4 further shows a first biasing mechanism 433 that is pressing on the ball 432 to push it outside the sleeve 422, toward the plug 480.
  • the first biasing mechanism 433 may be a spring or similar element.
  • the purpose of the first biasing element 433 is to force the ball 432 to exit the setting tool when the swinging arm 434 allows the ball to move.
  • the second biasing mechanism 446 may also be implemented as a spring or similar element.
  • the purpose of the second biasing mechanism 446 is to prevent the swinging arm 434 to open, which would allow the ball 432 to exit the sleeve 422.
  • FIG. 5 shows the sleeve 422 being withdrawn inside the housing 420 while the end 442A of the pushing arm 442 extends, along the longitudinal axis X, beyond the housing 420 of the setting tool. Also note that although the setting tool 410 has been separated and pulled away from the plug 480, the ball 432 remains trapped inside the sleeve 422 by the holding mechanism 430.
  • the setting tool is armed for ball release. After enough perforations are made into the casing, the operator may decide to release the ball.
  • the pump at the surface is used to pump the guns and the setting tool down onto the plug 480, so that the pushing arm 442 contacts the plug 480.
  • the pushing arm 442 then starts to move along the negative direction of the longitudinal axis X, and shoulder 444 engages the swinging arm 434, which results in the swinging arm 434 being rotated about the fixed point 436, backward, i.e., in the upstream direction, as illustrated in Figure 6.
  • the ball 432 is freed and, due to the force exerted by the first biasing mechanism 433, it moves out of the setting tool with a speed V, toward the plug 480.
  • the ball 432 will end up on its seating 485, formed in the plug 480, as illustrated in Figure 7.
  • the casing 470 is completely sealed at the plug location, as the fluid in the well cannot move either through the bore 488 (which is blocked by the ball 432) or through the exterior of the plug 480 (which is sealed by the sealing element 482).
  • the ball 432 was not released from the setting tool as soon as the setting tool was separated from the plug as is the case in the art, but rather it was released when the operator of the setting tool decided, by pushing the setting tool towards the plug and rotating the swinging arm 434 to release the ball. In this way, the release of the ball from the setting tool is controlled, which is not the case for the existing setting tools.
  • the holding mechanism 430 that holds and controls the release of the ball 432 can be implemented as an electronic device, as now discussed with regard to Figure 8.
  • the setting tool 410 in Figure 8 has the housing 420 and the sleeve 422 similar to the embodiment illustrated in Figures 4-7.
  • the ball 432 is also placed inside the sleeve 422 as in the previous embodiments.
  • the holding mechanism 430 which instead of having a pushing arm that presses against the plug 480 for releasing the ball, has electronic components that release the ball.
  • the holding mechanism 430 in Figure 8 has an inner cavity 810, located toward the upstream end 410A of the setting tool.
  • the inner cavity 810 is fluidly isolated from the remaining of the sleeve 422, by a dividing wall 812.
  • a hole 814 is formed in the dividing wall 812 for allowing a rotating arm 820 to extend from the inner cavity 810 into the open part 422A of the sleeve 422.
  • the rotating arm 820 is connected to a partial gear 830 located inside the inner cavity 810.
  • a motor 840 is also located inside the inner cavity 810.
  • a gear 842 is attached to the motor 840.
  • the partial gear 830 is connected to the gear 842, so that the motor 840 can turn the rotating arm 820 in one of two possible angular directions.
  • One or more O-rings 850 or other equivalent elements are placed between the rotating arm 820 and the dividing wall 812 to prevent the well fluid from the open part 422A of the sleeve 422 to enter inside the inner cavity 810.
  • the inner cavity 810 is maintained at atmospheric pressure, so that no fluid enters inside and the motor 840 and other elements (to be discussed later) are insulated from the harsh environment that might be present inside the open part 422A of the sleeve 422.
  • One or more thrust washers 822 may be provided between the dividing wall 812 and the rotating arm 820.
  • the rotating arm 820 has an extending arm 824 that extends from a rotational axis RA toward the sleeve 422, to create an enclosure 826 in which the ball 432 is trapped.
  • a cross-section A-A trough the setting tool 810 is shown in Figure 9 and illustrates the partial gear 830 being engaged with the gear 842.
  • the partial gear 830 can be rotated by the full gear 842, which is rotated by the motor 840, to move from a closed position A to an open position B.
  • the corresponding motion of the extending arm 824 is shown in Figure 10, which corresponds to the cross-section B-B through the setting tool 810 of Figure 8. Note that the extending arm 824 have been moved from the closed position A to the open position B, so that the ball 432 is freed. Due to the biasing mechanism 433 shown in Figure 8, the ball 432 is now pushed out of the setting tool, and by controlling the pressure inside the well, the ball 432 can be placed in its seating of the plug 480, as in Figure 7.
  • the motor 840 may be actuated in various ways for freeing the ball 432.
  • a cable 844 (see Figure 8) that extends from the motor 840 all the way to the surface, to a global controller located at the head of the well.
  • the global controller supplies power along the cable 844. If such a cable is implemented along the gun string and the setting tool, it needs to be protected such that the firing of the shaped charges do not destroy the integrity of the cable.
  • the motor 840 may be controlled by a local controller 1 100, which is also located inside the inner cavity 810.
  • Local controller 1 100 which is discussed in more detail later, may be connected to a power supply 1 1 10 (e.g., a battery), and to one or more sensors 1 120.
  • a trigger signal is detected by the sensor 1 120, the controller activates the motor 840, to release the ball 832 similar to the embodiment illustrated in Figure 8.
  • the sensor 1 120 may be implemented in various ways, as now discussed.
  • the senor 1 120 may be implemented as an acoustic sensor. After a shaped charge of a gun is fired, the noise would be detected by the acoustic sensor. The signal generated by the acoustic sensor is transmitted to the controller, which compares an intensity of the signal to a given threshold. The firing of a shaped charge generates an intense signal. The presence of the intense signal confirms that perforations were made. Thus, the controller 1 100 activates the motor 840 to release the ball 432.
  • a system 1200 in which there is an acoustic transmitter 1220 at the top of the well 1202.
  • the acoustic transmitter 1220 is controlled by a global controller 1230 and can emit an acoustic signal that propagates through the well fluid 1204 to the acoustic sensor 1 120.
  • the operator at the surface 1206 could send an acoustic signal with the transmitter 1220.
  • This acoustic signal is detected by the sensor 1 120 and interpreted by the controller 1 100 as a signal to activate the motor 840 and release the ball 432.
  • the signal emitted by the transmitter 1220 may be preset into the local controller 1 100 so that only for that specific acoustic signal the controller activates the motor 840.
  • a shaped charge 1212 associated with the gun string 1210 creates a pressure pulse when fired.
  • This pressure pulse can be used as the signal for instructing the controller 1 100 to activate the motor 840.
  • the sensor 1 120 is a pressure sensor that is located outside the inner cavity 810.
  • the senor 1 120 is an accelerometer.
  • the gun string 1210 fires, the gun string and also the setting tool 410, which is fixedly connected to the gun string 1210, experience a sudden movement (a jump).
  • the accelerometer 1 120 detects this jump and a signal indicative of it is sent to the controller 1 100.
  • the controller 1 100 stores in a memory a threshold value and compares the jump experienced by the accelerometer with the threshold value. If the jump value is larger than the threshold value, the controller determines that the gun string has fired and motor 840 is activated to release the ball 432.
  • the operator at the surface may raise or lower the setting tool 410, which is connected to a wireline 1240 or equivalent device, according to a known pattern.
  • the controller When the controller identifies the pattern based on the signals measured by the accelerometer 1 120, the controller instructs the motor 840 to rotate to release the ball 432.
  • the gun string and setting tool may be moved with a certain velocity pattern and the sensor 1 120 may be selected to measure this velocity.
  • the controller instructs the motor 840 to rotate to release the ball 432.

  • the mechanical enclosure 1310 is mechanically attached, trough internal connecting element 1320, to the inside of the sleeve 422.
  • the well fluid 472 is able to enter inside the sleeve 422, through ports 420A formed in the housing of the setting tool 410 and ports 422A formed in the sleeve and move along paths 1330, from outside the setting tool to its inside.
  • the ports are made into the housing 420 and the sleeve 422 so that the paths 1330 take the well fluid behind the ball 432, to push the ball outside the setting tool.

  • the operator moves the setting tool with a high velocity (which depends on the viscosity of the well fluid, diameter of the ports in the housing and sleeve, size of the ball, etc.) so that the well fluid 472 acts with a force against the ball and also makes the flexible walls 1312 of the mechanical enclosure 1310 to vibrate as indicated by arrows 1340, which eventually results in the mechanical enclosure flexing radially outward and the distance between the shoulders 1316 becoming larger than the diameter of the ball, so that the ball is released from the mechanical enclosure 1310 and ultimately from the setting tool 410.
