Definitions
- Treatment including fracturing is an important part of operations in a borehole environment whether for resource recovery or fluid sequestration.
- Treating apparatus tend to be complicated with a number of tools required and need to be run on pipe or coiled tubing.
- Fracturing is typically undertaken from the bottom up in a borehole using different sized plugs starting with the smallest at the most downhole target of the interval to be fractured and increasing plug size by a small amount for each subsequent fracture zone moving in the uphole direction.
- the operations are costly and time consuming such that the art is receptive to alternative methods and systems for accomplishing fracture or refracture in the borehole.
- An embodiment of a treatment system including a settable and unsettable seal sub, an operation sub connected to the seal sub, the operation sub including a flow restrictor, and a selectively openable port biased to a closed position.
- An embodiment of a borehole system including a slickline, and a resettable seal connected to the slickline and runnable in the borehole on the slickline.
- a method for treating a formation adjacent a borehole including running the treatment system on a slickline to a target depth, flowing past the flow restrictor thereby causing the flow restrictor and a mandrel upon which the restrictor is mounted to move toward the seal sub, partially setting the seal sub and increasing pressure on the seal sub thereby fully setting the seal sub.
- a borehole system including a borehole in a subsurface formation, a treatment system disposed within the borehole.
- Figure 5 is a schematic view of a borehole system within which is disposed the treatment system disclosed herein.
- a treatment system 10 which treatment may be fracturing, acidizing, etc.
- the system 10 comprises a settable and resettable seal sub 12 and an operation sub 14 connected to the seal sub 12.
- the seal sub 12 includes an element 16 disposed on a mandrel 18.
- a cone 20 is also disposed on the mandrel 18.
- a mandrel extension 22 is attached to the mandrel 18 and includes a J-slot groove 24 therein.
- An anchor sleeve 26 is slidably disposed on the mandrel 18 and mandrel extension 22.
- the sleeve 26 includes a slip 28, a drag block 30 and a J-slot follower 32 (see FIG. 3).
- the sleeve may be displaceable relative to the cone 20 sufficiently to actuate the slip 28 and anchor the system 10 in a borehole or casing (radially outwardly located relative to the system 10).
- the sleeve 26 is prevented from moving enough to engage the cone 20.
- the J-slot groove 24 causes rotation of the sleeve 26 from a running position where the sleeve is prevented from engaging the cone 20 to a setting position where the sleeve is permitted to engage the cone 20.
- the groove 24 has a longer segment running axially of the extension 22 to permit the desired motion of the sleeve 26 into engagement with the cone 20.
- the seal sub 12 further includes an equalization port housing 34 having an equalization port 36. When the port 36 is open, flow can pass from outside of system 10 from uphole thereof through port 36 and then inside of the seal sub 12 to downhole of the system 10.
- the operation sub 14 includes a flow restrictor 38 disposed upon a port control mandrel 40.
- Flow restrictor 38 may be an upset member or may be one or more cups, or may be other structures that reduce flow area between the restrictor 38 and the borehole in which the system 10 is disposed.
- the port control mandrel 40 is slidable in the port housing 34 of the seal sub 12 and depending upon its position relative thereto will either cover or uncover the port 36.
- Sub 14 further includes an unloading port 42 (see FIG. 2) uphole of the restrictor 38. The port 42 is covered or uncovered based upon a position of an unloader mandrel 44, slidable relative to the port control mandrel 40.
- the mandrel 44 is biased to a port 42 closed position by a spring 46 and may be moved to a port 42 open position through the application of a tensile load on the mandrel 44 from a slickline 48 upon which the system 10 is run.
- the system 10 is run into a borehole in the position illustrated in Figure 1 on slickline 48.
- the slickline is pulled up by a short distance of about a foot. Because the anchor sleeve 26 includes the drag block 30 (two visible in the figure but any number is contemplated), the sleeve 26 will stay relatively stationary.
- a borehole system 50 is illustrated.
- the system 50 comprises a borehole 52 in a subsurface formation 54.
- a string 56 is disposed within the borehole 52.
- a treatment system 10 is disposed within or as a part of the string 56.
- Embodiment 1 A treatment system including a settable and unsettable seal sub, an operation sub connected to the seal sub, the operation sub including a flow restrictor, and a selectively openable port biased to a closed position.
- Embodiment 2 The system as in any prior embodiment, wherein the flow restrictor is an upset member.
- Embodiment 3 The system as in any prior embodiment, wherein the flow restrictor is responsive to fluid drag and differential pressure to move a mandrel toward the seal sub to actuate the seal sub.
- Embodiment 4 The system as in any prior embodiment, wherein the flow restrictor includes a cup.
- Embodiment 5 The system as in any prior embodiment, wherein the cup is a plurality of cups.
- Embodiment 6 The system as in any prior embodiment, wherein the operation sub includes a biaser configured to cause the bias to the closed position.
- Embodiment 7 The system as in any prior embodiment, wherein the biaser is a compression spring.
- Embodiment 8 The system as in any prior embodiment, wherein the port is openable by tension applied to the operation sub.

- Embodiment 13 The system as in any prior embodiment, wherein the seal is actuable for setting and unsetting responsive to slack off, overpull from the slickline.
- Embodiment 14 The system as in any prior embodiment, wherein the seal is further responsive to fluid flow for completion of the setting.
- Embodiment 15 A method for treating a formation adjacent a borehole including running the treatment system as in any prior embodiment on a slickline to a target depth, flowing past the flow restrictor thereby causing the flow restrictor and a mandrel upon which the restrictor is mounted to move toward the seal sub, partially setting the seal sub and increasing pressure on the seal sub thereby fully setting the seal sub.
- Embodiment 16 The method as in any prior embodiment, further comprising pressuring up to fracture the formation.
- Embodiment 17 The method as in any prior embodiment, further comprising pulling on the system to cycle a J-slot to a position where setting is enabled.
- Embodiment 18 The method as in any prior embodiment, further including pulling on the system, equalizing pressure across the seal, opening a port uphole of the restrictor, and tripping the system to another target location.
- Embodiment 19 The method as in any prior embodiment wherein the another target location is downhole of the previous target location.
- Embodiment 20 A borehole system, including a borehole in a subsurface formation, a treatment system as in any prior embodiment disposed within the borehole.
- the teachings of the present disclosure may be used in a variety of well operations. These operations may involve using one or more treatment agents to treat a formation, the fluids resident in a formation, a borehole, and / or equipment in the borehole, such as production tubing.
- the treatment agents may be in the form of liquids, gases, solids, semi-solids, and mixtures thereof.
- Illustrative treatment agents include, but are not limited to, fracturing fluids, acids, steam, water, brine, anti-corrosion agents, cement, permeability modifiers, drilling muds, emulsifiers, demulsifiers, tracers, flow improvers etc.
- Illustrative well operations include, but are not limited to, hydraulic fracturing, stimulation, tracer injection, cleaning, acidizing, steam injection, water flooding, cementing, etc.
