Abstract

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. 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.

Claims (15)

What is claimed is:
1. A treatment system (10) characterized by: a settable (12) and unsettable seal sub; an operation sub (14) connected to the seal sub (12), the operation sub (14) including: a flow restrictor (38); and a selectively openable port biased to a closed position.
2. The system (10) as claimed in claim 1, wherein the flow restrictor (38) is an upset member.
3. The system (10) as claimed in claim 1, wherein the flow restrictor (38) is responsive to fluid drag and differential pressure to move a mandrel (40) toward the seal sub (12) to actuate the seal sub (12).
4. The system (10) as claimed in claim 1, wherein the flow restrictor (38) includes a cup.
5. The system (10) as claimed in claim 1, wherein the operation sub (14) includes a biaser configured to cause the bias to the closed position.
6. The system (10) as claimed in claim 1, wherein the port (42) is openable by tension applied to the operation sub (14).
7. The system (10) as claimed in claim 1, wherein the seal sub (12) includes a J- slot mechanism (32, 24).
8. The system (10) as claimed in claim 1, wherein the seal sub (12) includes a drag block (30).
9. A borehole system (50), characterized by: a slickline (48); and a resettable seal (12) connected to the slickline (48) and runnable in the borehole (52) on the slickline (48).
10. The system (50) as claimed in claim 9, wherein the seal (12) is actuable for setting and unsetting responsive to slack off, overpull from the slickline (48).
11. The system (50) as claimed in claim 10, wherein the seal (12) is further responsive to fluid flow for completion of the setting.
12. A method for treating a formation adjacent a borehole (52), characterized by: running the treatment system (10) as claimed in claim 1 on a slickline (48) to a target depth; 7 flowing past the flow restrictor (38) thereby causing the flow restrictor (38) and a mandrel (40) upon which the restrictor (38) is mounted to move toward the seal sub (12); partially setting the seal sub (12); and increasing pressure on the seal sub (12) thereby fully setting the seal sub (12).
13. The method as claimed in claim 12, further comprising pulling on the system (50) to cycle a J-slot to a position where setting is enabled.
14. The method as claimed in claim 12, further characterized by: pulling on the system (10); equalizing pressure across the seal; opening a port uphole of the restrictor (38); and tripping the system (10) to another target location.
15. A borehole system (50), characterized by: a borehole (52) in a subsurface formation (54); a treatment system (10) as claimed in claim 1 disposed within the borehole (52). 8
