A method of conducting a plurality of downhole operations with a completion system, the method including performing a treatment through a port in a first sleeve assembly in a first stage of the completion system, using an object to slide a first sleeve in a second sleeve assembly, located uphole of the first sleeve assembly, in a second stage of the completion system to reveal a port, and then closing the port in the first sleeve assembly in the first stage using the object, performing a treatment through the port in the second sleeve assembly, closing the port in the second sleeve assembly, and opening at least one of the ports in the first sleeve assembly and the second sleeve assembly and producing fluids through the at least one of the ports. A completion system includes the sleeve assemblies and object for performing the method.

What is claimed is: 1. A method of conducting a plurality of downhole operations with a completion system, the method comprising: opening a toe sleeve assembly port in a toe sleeve assembly in a first stage of the completion system and enabling circulation; performing a treatment through a first sleeve assembly port in a first sleeve assembly and through the toe sleeve assembly port in the first stage of the completion system; using an object in a second sleeve assembly, the second sleeve assembly located uphole of the first sleeve assembly and in a second stage of the completion system, the second sleeve assembly including a second sleeve assembly first sleeve and a second sleeve assembly port, using the object to slide the second sleeve assembly first sleeve to reveal the second sleeve assembly port, and then closing the first sleeve assembly port and the toe sleeve assembly port using the object; performing a treatment through the second sleeve assembly port; closing the second sleeve assembly port; and opening at least one of the first and second sleeve assembly ports and producing fluids through the at least one of the first and second sleeve assembly ports. 2. The method of claim 1 , wherein performing the treatment through the first sleeve assembly port and the toe sleeve assembly port and performing the treatment through the second sleeve assembly port includes performing an acid stimulation treatment through the first sleeve assembly and toe sleeve assembly ports and through the second sleeve assembly port to stimulate a borehole wall. 3. The method of claim 2 , wherein the first sleeve assembly port and the second sleeve assembly port each include a consumable plug to maintain sufficient pressure to pump the object therethrough, the method further comprising consuming the consumable plugs with acid from the acid stimulation treatment. 4. The method of claim 3 , wherein the second sleeve assembly port further includes a disc, the method further comprising rupturing the disc prior to the acid stimulation treatment of the borehole wall in the second stage. 5. The method of claim 1 , wherein the toe sleeve assembly includes a toe sleeve assembly first sleeve and a toe sleeve assembly second sleeve, the toe sleeve assembly first sleeve hydraulically openable to reveal the toe sleeve assembly port and the toe sleeve assembly second sleeve closable to close the toe sleeve assembly port. 6. The method of claim 1 , wherein the toe sleeve assembly includes a toe sleeve assembly first sleeve having a rupture disc, and opening the toe sleeve assembly port includes pressuring up within the toe sleeve assembly first sleeve to rupture the rupture disc and dump pressure on a piston to shift the toe sleeve assembly first sleeve and uncover the toe sleeve assembly port. 7. The method of claim 1 , wherein the object is a second object, and further comprising, prior to performing the treatment through the first sleeve assembly port, opening a first sleeve assembly first sleeve of the first sleeve assembly using a first object landed on a first sleeve assembly object seat in the first sleeve assembly first sleeve; the second object having a greater diameter than the first object. 8. The method of claim 7 , further comprising a plurality of second sleeve assemblies in the second stage, the method including sliding the second sleeve assembly first sleeve in each second sleeve assembly using the second object. 9. The method of claim 7 , wherein the second sleeve assembly further includes a second sleeve assembly second sleeve, wherein closing the second sleeve assembly port comprises using a third object to shift the second sleeve assembly second sleeve to cover the second sleeve assembly port, wherein the third object has a greater diameter than the second object. 10. The method of claim 9 , prior to using the third object to shift the second sleeve assembly second sleeve to cover the second sleeve assembly port, using the third object to open a third sleeve assembly port in a third sleeve assembly in a third stage isolated from the second stage. 11. The method of claim 1 , wherein the first and second sleeve assemblies include object seats to receive and release the object therethrough, the method further comprising milling out the object seats subsequent treatment performed through each stage of the completion system. 12. The method of claim 1 , wherein opening at least one of the first and second sleeve assembly ports for production includes engaging a shifting tool with a shifting profile on at least one of a first and second sleeve assembly second sleeve that is located over at least one of the first and second sleeve assembly ports. 13. The method of claim 12 , wherein the first and second sleeve assemblies include object seats for receiving and releasing the object therethrough, the method further comprising milling out the object seats on coiled tubing subsequent completion of treatment performed through each stage of the completion system, wherein the shifting tool for opening at least one of the first and second sleeve assembly ports is on the coiled tubing. 14. The method of claim 1 , further comprising flowback testing through the first sleeve assembly port and flowback testing through the second sleeve assembly port subsequent treatment and prior to production. 15. A method of conducting a plurality of downhole operations with a completion system, the method comprising: opening a toe sleeve assembly port in a toe sleeve assembly in a first stage of the completion system and enabling circulation, the toe sleeve assembly including a toe sleeve assembly first sleeve having a rupture disc, and opening the toe sleeve assembly port includes pressuring up within the toe sleeve assembly first sleeve to rupture the rupture disc and dump pressure on a piston to shift the toe sleeve assembly first sleeve and uncover the toe sleeve assembly port; performing a treatment through a first sleeve assembly port in a first sleeve assembly in the first stage of the completion system; using an object to slide a second sleeve assembly first sleeve in a second sleeve assembly in a second stage of the completion system, the second sleeve assembly located uphole of the first sleeve assembly, to reveal a second sleeve assembly port, and then closing the first sleeve assembly port using the object; performing a treatment through the second sleeve assembly port; closing the second sleeve assembly port; and opening at least one of the first and second sleeve assembly ports and producing fluids through the at least one of the first and second sleeve assembly ports; wherein the toe sleeve assembly further includes a toe sleeve assembly second sleeve having an object seat, and after closing the first sleeve assembly port in the first stage with the object, closing the toe sleeve assembly port in the toe sleeve assembly with the object landing on the object seat in the toe sleeve assembly second sleeve. 16. A completion system including a string of downhole tools arranged for a plurality of downhole operations, the completion system including: settable packers arranged to separate adjacent stages of the string from each other; a toe sleeve assembly in a first stage of the string, the toe sleeve assembly including a toe sleeve assembly housing, a toe sleeve assembly radial port in the toe sleeve housing, a hydraulically openable toe sleeve assembly first sleeve initially arranged to cover the toe sleeve assembly port, and an object-activated toe sleeve assembly second sleeve having a toe sleeve assembly second sleeve object seat,
