| Claim: | 1. A substance deposition and backflow preventing arrangement comprising: a housing having a port therein; a sleeve disposed within the housing and positionable to cover or uncover the port, the sleeve having a first seal at one end thereof presenting a first hydraulic dimension and a second seal at another end of the sleeve having a different hydraulic dimension; a convertible ball seat system disposed within the housing the system including a plurality of fingers each having a first end and a second end, each finger forming a portion of a first seat on the first end of each finger of the plurality of fingers and a portion of a check seat on the second end of each finger of the plurality of fingers, the first seat being sealable with a dropped ball to convert the system and the second seat being sealable with the ball to prevent backflow through the arrangement. |
| Claim: | 2. The arrangement as claimed in claim 1 wherein the sleeve further includes a release member configured to maintain a first position of the sleeve until an input causes release of the release member. |
| Claim: | 3. The arrangement as claimed in claim 1 wherein the second seal presents a smaller hydraulic dimension. |
| Claim: | 4. The arrangement as claimed in claim 1 wherein the convertible ball seat system comprises a first operative position wherein the first seat is sealingly receptive to the dropped ball and a second operative position wherein the first seat retains the dropped ball but allows flow past the dropped ball simultaneously with the second seat becoming sealingly receptive of the dropped ball so that the convertible ball system becomes a check valve with a ball dropped therein. |
| Claim: | 5. The arrangement as claimed in claim 1 further comprising a release member connected to the convertible ball seat system. |
| Claim: | 6. The arrangement as claimed in claim 1 further comprising: a second sleeve having a second ball seat within the housing, the sleeve movable between positions covering a check valve and covering the port. |
| Claim: | 7. The arrangement as claimed in claim 6 wherein the first ball seat is of smaller dimension than the second ball seat. |
| Claim: | 8. The arrangement as claimed in claim 6 wherein each sleeve further includes a release member configured to maintain an initial position of the associated sleeve until an occurrence of a selected input. |
| Claim: | 9. The arrangement as claimed in claim 6 wherein the check valve allows fluid flow radially outwardly of the housing and not radially inwardly of the housing. |
| Claim: | 10. A borehole system comprising: a tubing string disposed in the borehole; and a substance deposition and backflow preventing arrangement as claimed in claim 1 disposed as a part of the tubing string. |
| Claim: | 11. A convertible ball seat system comprising: a housing; a plurality of fingers disposed in the housing each having a first end and a second end, each finger forming a portion of a first seat on the first end of each finger of the plurality of fingers and a portion of a check seat on the second end of each finger of the plurality of fingers, the first seat being sealable with a dropped ball to convert the system and the second seat being sealable with the ball to prevent backflow through the system. |
| Claim: | 12. The system as claimed in claim 11 wherein the housing includes a recess engagable with the first ends of each finger of the plurality of fingers and a second recess engagable with the second ends of each finger of the plurality of fingers and engagement of the first ends of each finger of the plurality of fingers with the first recess causes the first seat to allow flow past the dropped ball while engagement of the second ends of each finger of the plurality of fingers with the second recess causes the second seat to allow passage of the dropped ball into the convertible ball seat system. |
