摘要:
A technique includes deploying a string that includes a seat assembly in a well; and running a shifting tool in a passageway of the string. The shifting tool shifts the seat assembly to cause the seat assembly to transition between a first state in which the seat assembly forms a seat that is adapted to allow an untethered object communicated in the passageway of the string to pass through the seat assembly to a second state in which the seat assembly is adapted to catch the object to form a fluid barrier in the string. The fluid barrier is used to divert fluid in the tubing string to perform, for example, a stimulation operation.
摘要:
A method of treating a downhole region penetrated by a wellbore with a treatment agent is given, including delivering the treatment agent to the wellsite enclosed in one or more destructible containers, inserting the one or more destructible containers into the fluid being pumped down the well, and mechanically breaking the one or more destructible containers in the wellbore or in the formation to release the treatment agent. A method is also given for treating a downhole region penetrated by a wellbore with a special solid diverting material, which includes special shapes such as fibers or flakes and/or blends of specially sized particles, including delivering the special solid diverting material to the wellsite enclosed in one or more containers, inserting the one or more containers into fluid being pumped down the well, and allowing the one or more containers to release the special solid diverting material in the wellbore.
摘要:
An apparatus includes a string that extends into a well and a tool that is disposed in the string. The tool is adapted to form a seat to catch an object communicated to the tool via a passageway of the string in response to the tool being perforated.
摘要:
The subject disclosure discloses mechanisms for embedding and controlling multifunctional additives within a polymer matrix for use in oilfield applications. More particularly, the subject disclosure discloses methods of treating a subterranean formation with a polymer matrix comprising one or a plurality of polymers and one or a plurality of functional additives embedded into this polymer matrix.
