Description

TECHNICAL FIELD

The present disclosure relates generally to oil and gas operations and, more particularly, to an object launching apparatus and related methods.

BACKGROUND

Due to the rapid expansion of additional fracturing zones involved in fracturing operations for a single well, the oil and gas industry has been driven to develop more efficient and cost effective well fracturing strategies. This has driven the market to produce ball- and sleeve- (or collet) based systems utilizing a number of methods and processes. One such method/process requires the balls dropped to be dissolvable. Other methods/processes require balls to be varied in size to properly be used in certain fracturing operations. Accordingly, there is a need for an object launching apparatus that can house an array of balls, collets, or any other to-be-launched objects in a housing that can be automated to deliver each of these objects in a specified sequence (if required) to a well. It would also be desirable for the object launching apparatus to maintain the array of balls, collets, or other to-be-launched objects in the housing in a dry and low-pressure environment. Therefore, what is needed is an apparatus or method that addressed one or more of the foregoing issues and/or one or more other issues.

DETAILED DESCRIPTION

Referring to FIG. 1, in an embodiment, an object launching apparatus is diagrammatically illustrated and generally referred to by the reference numeral 100. The object launching apparatus 100 is adapted to efficiently house and deliver objects into a wellbore 105 for various oilfield operations such as, for example, fracturing operations. In this regard, the object launching apparatus 100 can be designed to launch various types of objects desired to be deposited into the wellbore 105 for a particular oil and gas operation; for example, the objects can be “frac” balls or collets used in fracturing operations.

The object launching apparatus 100 includes an object container 110. In some embodiments, as in FIG. 1, the object container 110 is positioned on a bottom plate 115. A container actuator 120 is operably associated with, and adapted to displace, the object container 110. The container actuator 120 facilitates control and motivation of the object container 110 along multiple axes. The container actuator 120 may be, include, or be part of, motor(s), cylinder actuator(s), other actuators powered by electric, pneumatic, or hydraulic power, or any combination thereof. At the same time, one or more position sensors 125 are adapted to detect the position of the object container 110. The position sensor(s) 125 may be, include, or be part of encoder(s), linear position transducer(s), wire potentiometer(s), another transducer capable of translating linear motion into a mechanical or electrical signal, or any combination thereof.

A plunger 130 is operably associated with, and adapted to launch objects from, the object container 110. A plunger actuator 135 is adapted to displace the plunger 130 to launch objects from the object container 110. A release chamber 140 is adapted to receive objects launched from the object container 110. A proximity sensor 145 is adapted to detect a presence of objects within the release chamber 140 (i.e., objects launched from object container 110). In some embodiments, the proximity sensor 145 is a camera. A releasing mechanism 150 is operably associated with, and adapted to release objects from, the release chamber 140.

The object launching apparatus 100 is operably associated with a wellhead 155. The wellhead 155 serves as the surface termination of the wellbore 105. In some embodiments, as in FIG. 1, one or more oil and gas tools 160 such as, for example, the valve apparatus described in U.S. patent application Ser. No. 15/487,785, filed on Apr. 14, 2017 and published under U.S. patent application publication number US 2017/0298708 A1, the entire disclosure of which is hereby incorporated herein by reference, can be operably associated with the wellhead 155. Accordingly, objects released from the release chamber 140 travel into the wellbore 105 only after passing through the one or more oil and gas tools 160 and the wellhead 155.

A controller 165 is adapted to send control signals to the container actuator 120, the plunger actuator 135, and the releasing mechanism 150, and to receive data from the position sensor(s) 125 and the proximity sensor 145. In some embodiments, the controller 165 is embedded in the object launching apparatus 100. In some embodiments, the controller includes software that runs algorithm(s) to precisely control the position of the object container to drop each object in a pre-specified release sequence. A user interface 170 is operably associated with the controller 165. In some embodiments, the user interface 170 is a laptop or touch panel (HMI).

In some embodiments, the controller 165 is further adapted to control the one or more oil and gas tools 160 and/or other tools/components associated with the wellhead 155. To this end, the controller 165 may include input/output capabilities for controlling: one or more valve(s) operably associated with the wellhead 155 and located above or below the object launching apparatus 100; one or more bleed lines operably associated with the wellhead 155; one or more equalizing lines operably associated with the wellhead 155; one or more backside pumps operably associated with the wellhead 155; or any combination thereof. In addition, or instead, the controller 165 can be configured as a slave device that is controlled from another controller or controllers operably associated with the wellhead 155; accordingly, the controller 165 may be configured to accept commands from the controller or controllers associated with the wellhead 155 in a manner similar to the manner in which the controller 165 accepts commands from the user interface 170 (as described below). An example embodiment of such an arrangement together with the corresponding sequence for dropping an object into the wellbore 105 from the object launching apparatus 100 is illustrated in FIG. 2A. Another example embodiment of such an arrangement together with the corresponding sequence for dropping object(s) into the wellbore 105 from the object launching apparatus 100 is illustrated in FIG. 2B.

Referring to FIGS. 3A-C with continuing reference to FIG. 1, an opening 175 is formed through the bottom plate 115 to permit the objects to pass through the bottom plate 115 and into the wellbore 105. The bottom plate 115 is positioned so that the opening 175 is generally aligned with the one or more oil and gas tools 160, the wellhead 155, and/or the wellbore 105. The bottom plate 115 defines opposing side portions 180a and 180b. The release chamber 140 can be at least partially defined by the space within the opening 175 between the opposing side portions 180a and 180b. In addition, at least a portion of the release chamber 140 can extend from the side portion 180b of the bottom plate 115. In an embodiment, as in FIGS. 3A-C, the object launching apparatus 100 can include vertically disposed guiderails 185 supported by the bottom plate 115 to keep the object container 110 on the bottom plate 115. The guiderails 185 can extend from a perimeter portion 180c of the bottom plate and/or from the side portion 180a of the bottom plate 115.

The object container 110 includes compartments 190 adapted to contain objects to be launched into the wellbore 105. In some embodiments, each of the compartments 190 is adapted to contain a single object to be launched into the wellbore 105. The object container 110 is movable on the bottom plate 115 to align each of the compartments 190 with the opening 175 so that the object contained therein can be dropped through the opening 175 and into the wellbore 105. In some embodiments, the bottom plate 115 is sized and shaped so that the object container 110 is supported regardless of which compartment 190′s object is being released through the opening 175 in the bottom plate 115. Once a particular one of the compartments 190 is aligned with the opening 175, the force of gravity may be sufficient to eject the object through the opening 175 and into the release chamber 140. However, if the force of gravity is not sufficient to eject the object, the plunger 130 can be employed in general alignment with the particular one of the compartments 190 and the opening 175 to push the object into the release chamber 140.

In some embodiments, as in FIGS. 3A-C, the objects are adapted to be contained in the compartments 190 by restraining devices 195. The restraining devices 195 are adapted to prevent, or at least reduce, movement of the objects within the compartment 190 during the oil and gas operation. In some embodiments, as in FIGS. 3A-C, the restraining devices 195 are feather-boards that provide frictional contact on, for example, four sides of the respective objects. In addition, or instead, other suitable restraining devices can be used to prevent, or at least reduce, movement of the objects within the compartments 190.

The compartments 190 can be laid out or oriented in a variety of configurations that allow each one of the compartments 190, and thus the object contained therein, to be aligned with the opening 175 in the bottom plate 115. For example, the layout or orientation of the compartments 190 can be a rectangular pattern, a spiral pattern, a ring pattern, multiple ring patterns, and the like. In an embodiment, the layout or orientation of the compartments 190 is based on a matrix of compartments N×N in number and movable along two primary axes of motion (e.g., x and y). For example, in the embodiment shown in FIGS. 3A-C, a 5×5 matrix of compartments is used to make up the object container, for a total of 25 compartments.

Referring to FIG. 4A with continuing reference to FIG. 1, in an embodiment, the user interface 170 provides the primary interface with the object launching apparatus 100 before and during operation. Before operation, the desired number and size of each object for a particular job can be entered into the user interface 170 and, once so entered, algorithm(s) in the user interface 170 can assign each object to a specified one of the compartments 190 in the object container 110. This arrangement is then communicated to the operator and the desired objects for the job are loaded into the object container 110, as indicated by arrows 200. Turning to FIG. 4B with continuing reference to FIG. 1, when a desired object is to be released, an operator requests the release via the user interface 170, which request is then sent as a digital message to the controller 165. Once the digital message is received, the software on the controller 165 runs algorithm(s) to generate the appropriate control signals to be sent to the container actuator 120. Upon receiving the control signals, the container actuator 120 moves the object container 110, as indicated by arrows 205, to position the object container 110 at a precise location in which the particular one of the compartments 190 containing the desired object is centered above the opening 175. The controller 165 receives feedback from the position sensor(s) 125 to validate that the particular one of the compartments 190 containing the desired object is in the correct position. Turning to FIG. 4C with continuing reference to FIG. 1, when it is time to release the desired object, the releasing mechanism 150 is opened and, once so opened, either gravity feeds the object downward or, if required, the plunger 130 pushes the object downward, as indicated by arrow 210. The controller 165 receives feedback from the proximity sensor 145 to verify successful release of the desired object and, once so verified, the releasing mechanism 150 is closed. The controller 165 then awaits another message from the user interface 170 to release the next object; in this manner the controlled release sequence can be repeated for all subsequent ones of the compartments 190.

Referring to FIG. 5 with continuing reference to FIG. 1, in certain oil and gas operations, it may be desirable to launch a large number of objects into the wellbore 105. To facilitate the launching of large numbers of objects into the wellbore 105, the object launching apparatus 100 can include a plurality of object containers substantially similar to the object container 110, which substantially similar object containers are given the same reference numeral 110, except that a subscript 1, 2, or N is added to each as a suffix. In some embodiments, as in FIG. 5, the object container 110₁ can include restraining devices substantially similar to the retraining devices 195 while the object containers 110_2-N do not include restraining devices substantially similar to the retraining devices 195. The object containers 110_2-N each have the same number of compartments 190 as the object container 110₁; as a result, the object containers 110_2-N can be stacked or otherwise positioned above the object container 110₁ so that the respective compartments 190 of the object containers 110_2-N are substantially aligned with the respective compartments 190 of the object container 110₁. In addition, to establish or maintain such substantial alignment, the object containers 110_1-N can each be secured to adjacent one(s) of the object containers 110_1-N (or to alignment components) such that each compartment 190 of a particular one of the object containers 110_1-N is in substantial alignment with the corresponding compartment 190 of an adjacent one of the object containers 110_1-N. One or more door elements 215 are operably associated with the compartments 190 of the object containers 110_2-N. The door element(s) 215 may be mechanically, hydraulically, pneumatically, or electrically actuable. More particularly, the door element(s) 215 are openable, as indicated by arrows 220, to drop a corresponding object into an aligned one of the compartments 190 positioned below. Once the object has passed into the compartment 190 positioned below, the door element(s) 215 are closable, as indicated by arrows 225.

The door element(s) 215 can each be or include any type of door element capable of dropping objects into the compartment 190 positioned below. For example, the door element(s) 215 can each be or include a door that pivots open or slides open. For another example, the door element(s) 215 can be actuable by a single action to drop all of the loaded objects from one of the object containers 110_2-N into the object container 110₁. Accordingly, the door element(s) 215 can include a lattice-type structure located underneath each of the object containers 110_2-N to contain the objects therein. Intersecting portions of the lattice-type structure can be centered under each object during containment. Then, when release of the objects in the one of the object containers 110_2-N is desired, the lattice-type structure is actuated using a single action in the diagonal direction to line up the intersecting portions of the lattice beneath the walls of the one of the object containers 110_2-N; this single action releases all of the objects at once into the object container 110₁.

In operation, in an embodiment, the object container 110₁ is emptied first. Once the object container 110₁ is empty, there is available space for additional objects to be launched. Thus, by actuating the door element(s) 215, the object container 110₂ above can deliver the objects contained therein to the object container 110₁ directly below. In some embodiments, the door element(s) 215 are actuable in a predetermined order to deliver objects to the compartments 190 of the object container 110₁ in a particular sequence. In some embodiments, all of the door element(s) 215 belonging to the object containers 110₂ are simultaneously actuable. In a similar manner, the object container 110_3-N can be emptied in sequence from bottom to top. More particularly, once the object container 110₁ (or at least one of the compartments 190 thereof) is empty, the door element(s) 215 are opened so that the objects contained in the object container 110₂ drop into the object container 110₁ (or into the at least one of the compartments 190 thereof). In addition, when the object containers 110₁ and 110₂ (or at least respective ones of the substantially aligned compartments 190 thereof) are empty, the door element(s) 215 are opened so that the objects contained in, for example, the object container 110_N drop into the object container 110₂ and then into the object container 110₁ (or into the at least respective ones of the substantially aligned compartments 190 thereof). In some embodiments, it is possible to leave all of the door element(s) 215 open after each drop sequence so that subsequently released objects drop directly through all of the compartments 190 positioned below; but some objects may be heavy and/or fragile, therefore a controlled drop (i.e., stopping in each of the object containers 110₁, 110₂, etc.) can be used.

Referring to FIG. 6, a method of operating the object launching apparatus 100 is diagrammatically illustrated and generally referred to by the reference numeral 230. The method 230 is carried out by receiving, at the controller 265, data from the position sensor(s) 125, the proximity sensor 145, or any combination thereof, and sending, from the controller 265, control signals to the container actuator 120, the plunger actuator 135, the releasing mechanism 150, or any combination thereof. More particularly, the method 230 includes: at a step 235 receiving from the position sensor(s) 125, using the controller 165, data relating to a detected position of the object container 110₁; at a step 240 sending, using the controller 165 and based on at least the data received from the position sensor(s) 125, control signals to the container actuator 120, said control signals causing the container actuator 120 to displace the object container 110₁ to sequentially align respective ones of the object container 110₁'s compartments 190 with the opening 175 so that objects loaded into respective ones of the object container 110₁'s compartments 190 are sequentially launched through the opening 175 and into the wellbore 105; at a step 245 receiving from the proximity sensor 145, using the controller 165, data relating to a detected presence of sequentially received ones of the launched objects within the release chamber 140; at a step 250 sending, using the controller 165 and based on at least the data received from the proximity sensor 145, control signals to the releasing mechanism 150, said control signals causing the releasing mechanism 150 to sequentially release objects from the release chamber 140 and into the wellbore 105; and at a step 255 sending, using the controller 165, control signals to the door element(s) 215 of at least one of the object containers 110_2-N, said control signals causing the door element(s) 215 to sequentially release objects loaded in respective ones of the at least one of the object containers 110_2-N's compartments 190 into the respective ones of the object container 110₁'s compartments 190. In some embodiments, the method 230 further includes sending, using the controller 165, control signals to the plunger actuator 135, said control signals causing the plunger actuator 135 to displace the plunger 130 to eject objects from the respective ones of the object container 110₁'s compartments 190 so that the objects are launched through the opening 175 and into the wellbore 105.

In some embodiments, among other things, the operation of the object launching apparatus 100 and/or the execution of the method 230: facilitates more efficient and cost effective well fracturing strategies; provides an array of balls, collets, or other to-be-launched objects in a housing that can be automated to deliver each of these objects in a specified sequence to the wellbore 105; and maintains the array of balls, collets, or other to-be-launched objects in the housing in a dry and low-pressure environment.
