Description

CONVEYANCE PROTECTION DEVICE, METHOD, AND SYSTEM CROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of an earlier filing date from U.S.Application Serial No.18 / 733,285 filed June 04, 2024, the entire disclosure of which is incorporated herein by reference. BACKGROUND

[0002] In the resource recovery and fluid sequestration industries coiled tubing,slickline, and electric wireline are commonly employed conveyances for various downhole tools. While these all work well for their intended purposes, the connections, such as the connector, rope socket or cablehead, to equipment conveyed thereon can sometimes fail where the equipment is stuck in the borehole in some way. Failures of this type can lead to well control incidents, something the art has lamented for decades. SUMMARY

[0003] An embodiment of a conveyance protection arrangement, including aconveyance, an interconnection that connects equipment to the conveyance, a protection device on the conveyance, the protection device being proud of the conveyance.

[0004] An embodiment of a method for running a conveyance in a borehole includingconnecting to the conveyance, a downhole tool, connecting to the conveyance, a protection device, running the conveyance with the tool and protection device through a stuffing box, pulling the conveyance out of the hole, and contacting the stuffing box with the protection device.

[0005] An embodiment of a borehole system, including a borehole in a subsurfaceformation, a string disposed in the borehole, a conveyance protection device, disposed within or as a part of the string.BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The following descriptions should not be considered limiting in any way.With reference to the accompanying drawings, like elements are numbered alike:

[0007] Figure 1 is a schematic view of a conveyance protection arrangement asdescribed herein;

[0008] Figure 2 is a view of a single split protection device as disclosed herein;

[0009] Figure 3 is a view of a plural split protection device as disclosed herein;

[0010] Figure 4 is a schematic view of an inside surface of the protector devicedescribed herein; and

[0011] Figure 5 is a view of a borehole system including the conveyance protectionarrangement as disclosed herein. DETAILED DESCRIPTION

[0012] A detailed description of one or more embodiments of the disclosed apparatusand method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0013] Referring to Figure 1, a conveyance protection arrangement 10 is illustrated.The arrangement 10 includes a conveyance 12, that may be a coiled tubing, a slickline, a wireline, etc. The arrangement 10 further includes a downhole tool 14 that is attached to the conveyance 12. Downhole tool 14 may be a bottom hole assembly or any other tool that requires running in the hole. The tool 14 is attached to the conveyance 12 via a connection 16 colloquially known as a “connector” for coiled tubing, a “rope socket” for slickline and a “cablehead” for electric wireline. The connection 16 is intended to maintain the interface between the conveyance 12 and the tool 14. Despite this purpose, there are ties when the tool 14 becomes detached from the conveyance 12. This can occur from the tool 14 being struck for example. Or the detachment could occur simply because a conveyance was pulled too fast and disrupted the connection 16. Regardless of reason for disconnection, the fact of disconnection means that the conveyance can possibly be withdrawn from the borehole right through the stuffing box 18 (see Fig.5), whereby leaving an opening to the borehole that is potentially not controlled. Such withdrawal of the conveyance from the borehole through the stuffing box is undesirable. Accordingly, a protector device 20 has been devised that will stay with the conveyance even if the connection 16 is lost. The device 20 increases the physical dimensions of the conveyance 12 radially so that it is not possible to pull theconveyance 12 directly out of the stuffing box 18 but rather would result in a bump, when the device 20 contacts the box 18. The bump may be used as a signal to the operator to stop pulling on the conveyor until appropriate alternate well control is established and the box 18 can be disassembled. After disassembly, the conveyance may be removed form the well without triggering a well control incident.

[0014] Referring to Figures 2 and 3, device 20 comprises a body 22 that is annularlyextending. In one embodiment, referring to Figure 2, the body is configured as a shaft collar with a single slit 24 and a fastener 26 configured to close and retain the device 20 around the conveyance 12. In an alternate embodiment, referring to Figure 3, the body is a shaft collar with a plurality of splits 24 and at least one, but up to each, split 24 having a fastener 26 to close and retain the device 20 around the conveyance 12.

[0015] Referring to Figure 4, an inside surface 28 of the device 20 is illustrated. Ananchoring feature 30 is presented on the surface 28, that is configured to prevent movement of the device 20 on the conveyance 12. The feature may be wickers 32 as shown, or may be surface roughness, knurling, hard particulate matter, etc.

[0016] Referring to Figure 5, a borehole system 40 is illustrated. The system 40comprises a borehole 42 in a subsurface formation 44. A string 46 is disposed within the borehole 42. A conveyance protection device 10 as disclosed herein is disposed within or as a part of the string 46.
