Dual sleeve valve system
A system and method for producing hydrocarbons from a well with a dual sleeve valve assembly. The dual sleeve valve assembly has a toe valve assembly and a production assembly. The toe valve assembly has a valve sleeve positioned in a valve housing comprising at least one fracturing port. The valve sleeve is shiftable to allow fluid through the least one fracturing port. The production assembly comprises a production sleeve positioned within a production outer housing comprising at least one screen port and at least one production port. A sand screen assembly disposed around the production outer housing. The production sleeve shiftable by a ball to allow fluid through the at least one screen port and the at least one production port.
1 . A dual sleeve valve system comprising:
a valve assembly comprising:
a valve outer housing comprising at least one fracturing port; and
a valve sleeve positioned within the valve outer housing to prevent fluid flow through the at least one fracturing port, the valve sleeve operable to shift to an open position and allow the fluid flow through the at least one fracturing port when pressure is applied to a bore of the dual sleeve valve system; and
a production assembly comprising:
a production outer housing comprising a screen port and a production port, the production outer housing extending along a tubing string, the screen port and the production port spaced apart from one another in a longitudinal direction with respect to the tubing string;
a sand screen assembly disposed around the production outer housing; and
a production sleeve comprising a seat and at least one compensation port positioned between the screen port and the production port, the production sleeve positioned within the production outer housing to prevent the fluid flow through the screen port and the production port and operable to shift to the open position to allow the fluid flow through the screen port and the production port and prevent the fluid flow through the at least one fracturing port.
2 . The dual sleeve valve system of claim 1 , wherein the valve assembly further comprises an atmospheric chamber connected with a sleeve chamber via at least one passageway initially blocked by a release member, the valve sleeve slidably mounted within the valve outer housing for movement between a closed position and an open position.
3 . The dual sleeve valve system of claim 2 , wherein the sleeve chamber is filled with a fluid and the fluid is held in the sleeve chamber by the release member.
4 . The dual sleeve valve system of claim 3 , wherein the atmospheric chamber is a chamber containing air or other gas; wherein the air or the other gas is compressed or displaced as the fluid is forced into the atmospheric chamber.
5 . The dual sleeve valve system of claim 2 , wherein the release member is a rupture disc.
6 . The dual sleeve valve system of claim 2 , further comprising a flow restrictor positioned along the at least one passageway to restrict the fluid flow of fluid in the sleeve chamber as the fluid moves along the at least one passageway.
7 . The dual sleeve valve system of claim 1 , wherein the seat receives a ball.
8 . The dual sleeve valve system of claim 1 , further comprising a ratchet mechanism that prevents the production sleeve from reverse motion and shifting back to a closed position.
9 . The dual sleeve valve system of claim 1 , wherein the sand screen assembly covers the production port and the screen port.
10 . A method for producing hydrocarbons from a well, the method comprising:
disposing a tubing string comprising a dual sleeve valve system within a wellbore;
shifting a valve sleeve of a valve assembly of the dual sleeve valve system to open at least one fracturing port in a valve outer housing of the valve assembly to allow fluid flow through the at least one fracturing port; and
shifting a production sleeve of a production assembly of the dual sleeve valve system, the production sleeve extending along the tubing string, a screen port and a production port spaced apart from one another in a longitudinal direction with respect to the tubing string to close the at least one fracturing port to prevent fluid flow through the at least one fracturing port and open the screen port and the production port in a production outer housing to allow fluid flow through a sand screen assembly of the production assembly and the screen port and the production port.
11 . The method of claim 10 , wherein the valve sleeve is initially held in a closed position by a release member.
12 . The method of claim 11 , wherein the valve assembly comprises an atmospheric chamber connected with a sleeve chamber via at least one passageway, and wherein the at least one passageway is initially blocked by the release member.
13 . The method of claim 12 , wherein the sleeve chamber is filled with a fluid and the fluid is held in the sleeve chamber by the release member.
14 . The method of claim 13 , wherein, during the shifting of the valve sleeve, the atmospheric chamber is a chamber containing air or other gas, and wherein the air or the other gas is compressed or displaced as the fluid is forced into the atmospheric chamber from the sleeve chamber via the at least one passageway.
15 . The method of claim 12 , wherein the release member is a rupture disc.
16 . The method of claim 12 , wherein a flow restrictor is positioned along the at least one passageway to restrict a flow of fluid in the sleeve chamber as the fluid moves along the at least one passageway.
17 . The method of claim 12 , further comprising increasing a pressure in the interior of the tubing string to initially open the at least one fracturing port of the valve assembly by shifting the valve sleeve by opening the release member.
18 . The method of claim 10 , wherein the production sleeve has a seat for a ball that is dropped down the tubing string, and wherein once the ball is seated in the seat, a pressure on the ball can be increased to shift the production sleeve.
19 . The method of claim 10 , further comprising a ratchet mechanism preventing the production sleeve from reverse motion and from shifting back to a closed position after the shifting of the production sleeve.
20 . The method of claim 10 , wherein the shifting of the production sleeve positions the sand screen assembly around the production outer housing and covers the production port and the screen port.
