Abstract

The present invention generally relates to a valve for use in an oilfield tool. The valve includes a valve body (140) and a valve member (100) disposed in the valve body. The valve member is movable between an open and closed position. The valve member includes an aperture therethrough. The valve further includes a pressure relief member (105) disposed in the aperture, whereby at a predetermined pressure the pressure relief member will permit fluid communication. In another aspect, the invention provides an apparatus and a method for introducing fluid into a tubular.

Claims

[Received by the International Bureau on 19 December 2003 ( 19.12.03 ): original claims 1-22 replaced by amended claims 1-21 ( 4 pages)]Please add new claims 1-21 as follows:
1. (New) A valve for use in an oilfield tool, the valve comprising: a valve body; a valve member disposed in the valve body, wherein the valve member is movable to an open position when the valve is inserted in a wellbore tubular and to a closed position when the valve is removed from the tubular; an aperture formed in the valve member, the aperture providing fluid communication through the valve in the closed position; and a pressure relief member disposed in the aperture, the pressure relief member preventing fluid communication through the valve in the closed position, whereby at a predetermined pressure the pressure relief member permits fluid communication.
2. (New) The valve as claimed in claim 1 , wherein the valve member further includes a longitudinal bore therethrough providing fluid communication through the valve in the open position.
3. (New) The valve as claimed in claim 1 or 2, further including a rotational member attached to the valve member to rotate the valve member in the valve body.
4. (New) The valve as claimed in claim 3, wherein the rotational member causes the valve member to rotate between the open and closed position, whereby in the open position the longitudinal bore aligns with a passageway and in the closed position the aperture aligns with the passageway.
5. (New) The valve as claimed in any of claims 1 to 4, further including a first and a second seal member disposed at the upper end of the valve body.
6. (New) The valve as claimed in any of claims 1 to 4, wherein the valve member in the closed position exposes the pressure relief member to a fluid pressure.
7. (New) The valve as claimed in claim B, wherein at the predetermined pressure the pressure relief member opens, thereby allowing fluid communication through the valve.
8. (New) The valve as claimed in any preceding claim, wherein the valve member is a ball valve.
9. (New) An apparatus to introduce fluid into a casing, the apparatus comprising: a body having a bore therethrough; and a valve disposed in the body for selectively controlling a fluid flow through the bore, the valve comprising: a valve member movable between an open position when the apparatus is inserted into the casing and a closed position when the apparatus is removed from the casing, the valve member including an aperture for providing selective communication through the valve in the closed position; and a pressure relief member disposed in the aperture, whereby at a predetermined pressure the pressure relief member permits fluid communication.
10. (New) The apparatus as claimed in claim 9, wherein the valve further includes a rotational member attached to the valve member to rotate the valve member between the open and closed position.
11. (New) The apparatus as claimed in claim 10, wherein the rotational member causes the valve member to rotate to the open position when the apparatus is inserted in the casing and to the closed position when the apparatus is removed from the casing.
242544, 1
16
12. (New) The apparatus as claimed in any of claims 9 to 11 , wherein the valve member further includes a longitudinal bore therethrough for providing fluid communication through the bore in the open position.
13. (New) The apparatus as claimed in any of claims 9 to 12, wherein the valve member in the closed position aligns the aperture with the bore, thereby exposing the pressure relief member to the fluid.
14. (New) The apparatus as claimed in claim 13, wherein the predetermined pressure causes the pressure relief member to open, thereby permitting fluid communication through the bore.
15. (New) The apparatus as claimed in any preceding claim, wherein the valve member is a ball valve.
16. (New) A method of introducing fluid into a tubular, comprising: locating an apparatus in the tubular, the apparatus comprising: a body having a bore therethrough; and a valve disposed in the body for selectively controlling a flow fluid through the bore, the valve including a valve member and a pressure relief member disposed in the valve member, wherein at a predetermined pressure the pressure relief member opens; opening the valve in the apparatus upon insertion into the tubular; pumping fluid through the apparatus; introducing fluid into the tubular; removing the apparatus from the tubular; and closing the valve and exposing the pressure relief member to fluid.
17. (New) The method as claimed in claim 16, wherein the valve member is movable between an open and a closed position.
18. (New) The method as claimed in claim 16 or 17, wherein opening the
17 valve allows fluid communication through the bore of the apparatus.
19. (New) The method as claimed in claim 16, 17 or 18, wherein the predetermined pressure causes the pressure relief member to permit fluid communication through the bore.
20. (New) A valve for use in an oilfield tool, the valve comprising: a valve body; and a valve member disposed in the valve body, the valve member movable between an open position as the valve is inserted into a casing and a closed position as the valve is removed from the casing, whereby in the closed position, the valve member will open at a predetermined pressure.
21. (New) A valve for use in an oilfield tool, the valve comprising: a valve body; a valve member disposed in the valve body and movable between an open and a closed position, the valve member including a longitudinal bore therethrough providing fluid communication through the valve in the open position; and a second longitudinal bore formed in the valve member, the second longitudinal bore including a pressure relief member disposed therein, whereby at a predetermined pressure the pressure relief member will permit fluid communication.
