Abstract

Disclosed herein is a wellbore servicing system, comprising a tubular string, a first sleeve system incorporated within the tubular string, the first sleeve system comprising a first sliding sleeve at least partially carried within a first ported case, the first sleeve system being selectively restricted from movement relative to the first ported case by a first restrictor while the first restrictor is enabled, and a first delay system configured to selectively restrict movement of the first sliding sleeve relative to the first ported case while the first restrictor is disabled; a second sleeve system incorporated within the tubular string, the second sleeve system comprising a second sliding sleeve at least partially carried within a second ported case, the second sleeve system being selectively restricted from movement relative to the second ported case by a second restrictor while the second restrictor is enabled.

Claims25

Dependent claims

A wellbore servicing system, comprising:

a tubular string;
a first sleeve system incorporated within the tubular string, the first sleeve system comprising a first sliding sleeve at least partially carried within a first ported case, the first sleeve system being selectively restricted from movement relative to the first ported case by a first restrictor while the first restrictor is enabled, and a first delay system configured to selectively restrict movement of the first sliding sleeve relative to the first ported case while the first restrictor is disabled;
a second sleeve system incorporated within the tubular string, the second sleeve system comprising a second sliding sleeve at least partially carried within a second ported case, the second sleeve system being selectively restricted from movement relative to the second ported case by a second restrictor while the second restrictor is enabled, and a second delay system configured to selectively restrict movement of the second sliding sleeve relative to the second ported case while the second restrictor is disabled;
and
a first wellbore isolator positioned circumferentially about the tubular string between the first sleeve system and the second sleeve system.

2 more elements

A method of servicing a wellbore, comprising:

positioning a tubular string within the wellbore, the tubular string comprising
a first sleeve system, wherein the first sleeve system is positioned within the wellbore proximate to a first zone of the wellbore, the first sleeve system being initially configured in an installation mode where fluid flow between a flow bore of the first sleeve system and a port of the first sleeve system is restricted;
a second sleeve system, wherein the second sleeve system is positioned within the wellbore proximate to a second zone of the wellbore, the second sleeve system being initially configured in an installation mode where fluid flow between a flow bore of the second sleeve system and a port of the second sleeve system is restricted;
isolating the first zone of the wellbore from the second zone of the wellbore;
and
passing a first obturator through at least a portion of the first sleeve system, thereby unlocking a first restrictor of the first sleeve system and thereby transitioning the first sleeve system to a delayed mode;
allowing the first sleeve system to transition from the delayed mode to a fully open mode;
and
communicating a fluid to the first zone of the wellbore via one or more ports of the first sleeve system.

A method of servicing a wellbore, comprising:

positioning a tubular string within the wellbore, the tubular string comprising
a first sleeve system, wherein the first sleeve system is positioned within the wellbore proximate to a first zone of the wellbore, the first sleeve system being initially configured in an installation mode where fluid flow between a flow bore of the first sleeve system and a port of the first sleeve system is restricted;
a second sleeve system, wherein the second sleeve system is positioned within the wellbore proximate to the first zone of the wellbore, the second sleeve system being initially configured in an installation mode where fluid flow between a flow bore of the second sleeve system and a port of the second sleeve system is restricted;
a third sleeve system, wherein the third sleeve system is positioned within the wellbore proximate to a second zone of the wellbore, the third sleeve system being initially configured in an installation mode where fluid flow between a flow bore of the third sleeve system and a port of the third sleeve system is restricted;
a fourth sleeve system, wherein the fourth sleeve system is positioned within the wellbore proximate to the second zone of the wellbore, the fourth sleeve system being initially configured in an installation mode where fluid flow between a flow bore of the fourth sleeve system and a port of the fourth sleeve system is restricted;
isolating the first zone of the wellbore from the second zone of the wellbore;
passing a first obturator through at least a portion of the first sleeve system and at least a portion of the second sleeve system, thereby unlocking a first restrictor of the first sleeve system and a second restrictor of the second sleeve system and thereby transitioning the first sleeve system and the second sleeve system to a delayed mode;
allowing the first sleeve system and the second sleeve system to transition from the delayed mode to a fully open mode;
communicating a fluid to the first zone of the wellbore via one or more ports of the first sleeve system and one or more ports of the second sleeve system while not communicating a fluid to the second zone;
passing a second obturator through at least a portion of the third sleeve system and at least a portion of the fourth sleeve system, thereby unlocking a third restrictor of the third sleeve system and a fourth restrictor of the fourth sleeve system and thereby transitioning the third sleeve system and the fourth sleeve system to a delayed mode;
allowing the third sleeve system and the fourth sleeve system to transition from the delayed mode to a fully open mode;
and
communicating a fluid to the second zone of the wellbore via one or more ports of the third sleeve system and one or more ports of the fourth sleeve system.
