This application claims priority under 35 U.S.C. § 119(e) to U.S. Patent Application No. 62/879,987, entitled “MOVEABLE BOP TRANSPORT SKID,” by Padira P. REDDY, Denver C. LEE, Ralph D. SHAMAS, JR., and Sean M. BAILEY filed Jul. 29, 2019, which application is assigned to the current assignee hereof and incorporated herein by reference in its entirety.
BACKGROUNDEmbodiments of the present disclosure relate generally to the field of drilling and processing of wells. More particularly, present embodiments relate to a system and method for operating a moveable BOP transport skid to move a BOP stack from one well to another where multiple wells are at a same well site.
Some well sites can include two or more wells, such as with an array of wells. To drill and produce fluids from the various wells at the well site, a rig and various support equipment (e.g. a Blowout Preventer (BOP) stack) can be transported between the wells in the array to perform the subterranean operations. A BOP stack is large and heavy, and currently requires various support equipment (e.g. cranes, lifts, wheeled vehicles, etc.) to hoist a BOP stack from one well head at one location, transport the BOP stack to another location at the well site, and attach the BOP stack to another well head at other location. Therefore, improvements in BOP stack handling systems are continually needed.
SUMMARYIn accordance with an aspect of the disclosure, a system for conducting a subterranean operation is provided, where the system can include a blowout preventer (BOP) stack, a chassis coupled to the BOP stack, and one or more transport devices coupled to the chassis and configured to transport the chassis and the BOP stack from a first location to a second location.
In accordance with another aspect of the disclosure, a method for conducting subterranean operations is provided, where the method can include operations of mounting a blowout preventer (BOP) stack to a chassis, the chassis comprising one or more transport devices, and moving, via the one or more transport devices, the chassis from a first location to a second location.
These and other features, aspects, and advantages of present embodiments will become better understood when the following detailed description is read with reference to the accompanying drawings in which like characters represent like parts throughout the drawings, wherein:
Present embodiments provide a system and method for transporting a BOP stack between multiple well locations at a well site using a dedicated transport skid. The transport skid can include a controller in a sealed housing that moves with the transport skid. The controller can control the operation of the transport skid. The aspects of various embodiments are described in more detail below.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive-or and not to an exclusive-or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
The use of “a” or “an” is employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural, or vice versa, unless it is clear that it is meant otherwise.
The use of the word “about”, “approximately”, or “substantially” is intended to mean that a value of a parameter is close to a stated value or position. However, minor differences may prevent the values or positions from being exactly as stated. Thus, differences of up to ten percent (10%) for the value are reasonable differences from the ideal goal of exactly as described. A significant difference can be when the difference is greater than ten percent (10%).
It should be noted that the X-Y-Z coordinate axes are indicated in
The BOP transport skid 100 can be operated to move along the surface 6 by a controller 114 (in a housing 116) that can receive operator 30 inputs from either of the control consoles 104, 106. The rear control console 104 can be used by the operator 30 if he wishes to ride along with the BOP transport skid 100 as it moves along the surface 6. The side control console 106 can be used by the operator 30 if he wishes to walk beside the BOP transport skid 100 as it moves along the surface 6. The side control console 106 can be stowed away on an arm that is rotated to be parallel to the long side of the chassis 102. If the operator 30 wishes to use the side control console 106, the operator 30 can rotate the arm (arrows 82) from a position parallel to the long side of the chassis 102 to a position perpendicular to the long side of the chassis (as seen in
In operation, the BOP stack 120 (held by the BOP support frame 122) is usually oriented in a horizontal position relative to the chassis 102 during transport of the BOP transport skid 100 along the surface 6. With the BOP stack 120 secured in the horizontal position, the operator 30 can operate the transport devices 130 to propel the BOP transport skid 100 along the surface 6. In an unselected state, the vertical actuator of the transport device 130 is retracted causing the respective pad to be lifted from the surface 6 and allows the chassis 102 to rest on the surface 6. In a selected state, the vertical actuator of the transport device 130 is extended causing the respective pad to engage the surface 6 and lift the chassis 102 from the surface 6.
With all transport devices 130 in a selected state, the BOP transport skid 100 can be held above the surface 6, and the horizontal actuator of each respective transport device 130 can be actuated to move the chassis 102 horizontally relative to the pad, thereby propelling the BOP transport skid 100 along the surface 6, since the pads are engaged with the surface and the chassis moves horizontally relative to the pads. The vertical actuator of each respective transport device 130 can then be retracted to rest the chassis 102 back on the surface 6 and lift the pads from the surface 6. The pads can then be reset to their initial horizontal position before the movement of the BOP transport skid 100, thereby positioned to go again. This can be called a “step” when the pads lift the chassis 102 from the surface 6, propel the chassis 102 relative to the pads horizontally (i.e. in the X-Y plane relative to the chassis 102), and set the chassis 102 back down on the surface to allow the pad positions to be reset. As the operator 30 initiates multiple steps, the BOP transport skid 100 can be transported from one well head to another well head. Again, the BOP transport skid 100 can be steered as it is transported along the surface 6 by selectively rotating (arrows 80) various ones of the transport devices 130.
The BOP alignment system 124 can raise and lower the BOP stack in the Z-direction (arrows 88), move the BOP stack 120 horizontally in an X-Y plane (arrows 84 and 86), and rotate the BOP stack (arrows 92) in order to align the flange 126 with the flange 26. The BOP alignment system 124 can also tilt that BOP stack 120 away from the Z-axis to cause the flange 126 to be co-planar (i.e. substantially parallel) to the flange 26. If the BOP stack 120 needs further tilting about the Y-axis (i.e. about pivot 112), the actuator 110 can be used to further tilt the BOP stack. When the flanges 126, 26 are aligned with each other (i.e. the center axis 70 aligned with the center axis 72), the BOP stack can be lowered to the well head, thereby engaging the flange 126 with the flange 26. When these flanges 126, 26 are fastened together, the BOP stack can support subterranean operations at the well head. The BOP alignment system 124 can include various actuators to allow manipulation of the BOP stack relative to the chassis 102 and/or the support frame 122 to align the BOP stack with the well head.
However, in this example, the transport devices 130 are continuous tread devices 130. Each continuous tread device 130 can include a continuous tread 132 that travels on the outside of a drive motor 134 and multiple guide pulleys. As the drive motor 134 rotates, the continuous tread 132 is forced to travel around a perimeter of the respective continuous tread device 130. When the continuous tread devices 130 are engaged with the surface 6 and the chassis 102 is lifted above the surface 6, the BOP transport skid 100 can be propelled along the surface 6 by driving the continuous treads to move the BOP transport skid 100 relative to the surface.

The BOP transport skid 100 can be propelled along the surface 6 by driving the continuous treads to move the BOP transport skid 100 relative to the surface.

Once operations utilizing the BOP stack are halted at the first well location 160, the BOP stack can be disconnected from the well head at the first well location 160 and transported to a second well location 160. BOP transport skid 100 can transport the BOP stack from the first well location 160 to the second well location 160. With the BOP stack 120 held by the BOP support frame 122 in a vertical position, the BOP stack can be disconnected from the well head at the first well location 160, by unfastening the flange 126 of the BOP stack from the flange 26 of the well head at the first well location 160. The BOP stack 120 can then be lifted up and off the flange 26 and rotated to a horizontal position for transport along the surface 6.
