Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The RPE includes a first composition and a second composition that changes phase or strength under wellbore conditions. After a stage is perforated, RPEs are deployed to isolate toe ward pressure communication. The second composition changes phase to create flow channels in the RPE during production. In an alternate system/method, the second composition changes phase or strength thereby deforming the RPE to reduce size and pass through the RSM' s. The RPEs are removed or left behind prior to initiating well production without the need for a milling procedure.

Abstract: Certain aspects are directed to capturing data regarding physical states associated with a perforating string. In one aspect, a sensing tool is provided. The sensing tool includes at least one sensor and a processor positioned in an isolated chamber of the sensing tool. The processor samples data from the sensor at a first sampling rate associated with the deployment of a perforating string. The data is associated with at least one parameter with respect to the perforating string. The processor detects a trigger condition associated with a perforation operation of the perforating string. The processor switches to a second sampling rate in response to detecting the trigger condition. The second sampling rate is greater than the first sampling rate and is associated with the perforation operation. The processor samples data at the second sampling rate for a period of time in which the perforation operation is at least partially performed.

Abstract: Methods and apparatus for perforating a formation in a wellbore without perforating a well bore casing. The methods and apparatus include an external casing perforating device configured so as not to perforate the casing. The interior of the perforating device serves as a fluid flow path between the casing and the formation following perforation and a valve in the casing selectively opens and closes the flow path.
