| 20090120640 | Methods of Integrating Analysis, Auto-Sealing, and Swellable-Packer Elements for a Reliable Annular Seal - A variety of methods are disclosed, including, in one embodiment, a method of cementing comprising: introducing a pipe string into a well bore such that an annular space is defined between the pipe string and a wall of the well bore, wherein an annular structure is coupled to the pipe string, and wherein the annular structure comprises an expandable material; and introducing a cement composition into the annular space, wherein the cement composition comprises cement, water, and a component capable of responding to a crack formed in the cement composition after setting to inhibit flow of fluid through the crack. In certain embodiments, the method further comprises choosing the cement composition based at least partially on an analysis of well incidents. | 05-14-2009 |
| 20100050905 | ACTIVATING COMPOSITIONS IN SUBTERRANEAN ZONES - The present disclosure is directed to a system and method for managing cement in a subterranean zone. In some implementations, a method of cementing in a subterranean formation includes positioning a cement slurry including a plurality of activation devices in a wellbore. The activation devices configured to release an activator that increases a setting rate of the cement slurry. A signal is transmitted to at least a portion of the cement slurry to activate the activation devices. The activation device releases the activator in response to at least the signal. | 03-04-2010 |
| 20100051275 | METHODS OF ACTIVATING COMPOSITIONS IN SUBTERRANEAN ZONES - The present disclosure is directed to a system and method for managing cement in a subterranean zone. In some implementations, a method of cementing in a subterranean formation includes positioning a cement slurry including a plurality of activation devices in a wellbore. The activation devices configured to release an activator that increases a setting rate of the cement slurry. A signal is transmitted to at least a portion of the cement slurry to activate the activation devices. The activation device releases the activator in response to at least the signal. | 03-04-2010 |
| 20110048711 | METHODS OF SONICALLY ACTIVATING CEMENT COMPOSITIONS - The present disclosure is directed to a system and method for sonically activating cement slurries. In some implementations, a method of treating a subterranean formation includes positioning a settable composition including a capsule in a wellbore. The capsule is used to increase a setting rate in response to at least sonic signals. A sonic signal is transmitted to at least a portion of the settable composition to release an activator from the capsule. | 03-03-2011 |
| 20110048713 | Radiation-Induced Triggering for Set-On-Command Compositions and Methods of Use - The present invention relates to methods useful for isolating a portion of a wellbore. In one embodiment, a method includes preparing a sealant composition containing a set modifier component. The sealant composition is placed into the wellbore and is subjected to ionizing radiation that alters the set modifier component, triggering the thickening of the sealant composition. | 03-03-2011 |
| 20110054068 | Radiation-Induced Triggering for Set-On-Command Compositions - The present invention relates to compositions useful for isolating a portion of a wellbore. In one embodiment, a composition includes a sealant composition containing a wellbore treatment fluid and a set modifier component. The sealant composition can be placed into the wellbore and subjected to ionizing radiation that alters the set modifier component, triggering the setting of the sealant composition. | 03-03-2011 |
