  • Patent number: 10526531
    Abstract: A method for treating a subterranean formation penetrated by a wellbore, comprising: providing a treatment slurry comprising a carrying fluid, a solid particulate and an agglomerant; injecting the treatment slurry into a fracture to form a substantially uniformly distributed mixture of the solid particulate and the agglomerant; and transforming the substantially uniform mixture into areas that are rich in solid particulate and areas that are substantially free of solid particulate, wherein the solid particulate and the agglomerant have substantially dissimilar velocities in the fracture and wherein said transforming results from said substantially dissimilar velocities is provided.
    Type: Grant

  • Publication number: 20150369028
    Abstract: Compound cluster placement in fractures. A fracture treatment method includes forming propped regions having a larger coverage area than channels between the propped regions, and channelizing the propped regions in situ. Also disclosed are systems to treat a fracture interval and to produce reservoir fluids from a formation.

  • Publication number: 20150369029
    Abstract: Proppant cluster placement in fractures with foamed carrying fluid. A formation treatment method includes injecting a treatment fluid stage, having a particulate-containing substage containing a self-agglomerating solid composition and a foamed carrying fluid, above a fracturing pressure, and alternating pulses of a pumping parameter to transform the self-agglomerating composition into a channelized solids pack, and closing the fracture. Also disclosed are methods of modeling a fracture treatment interval for such a method, and methods of treatment and systems to treat with such a treatment fluid stage, wherein solid particulate-rich substages are larger than the solid particulate-lean substages to form particulate-rich island regions, an interconnected network of open channel regions between the island regions and the island regions are channelized to form particulate clusters within the island regions separated from adjacent particulate clusters by open voids in the island regions.

  • Publication number: 20150361761
    Abstract: A technique that is usable with a well includes deploying a cable-conveyed object in a passageway of a string in the well; using the object to sense a property of an environment of the string and communicating an indication of the sensed property to an Earth surface of the well; remotely controlling an operation of the object to change a state of a first downhole valve assembly based at least in part on the communication; and using the object to control a state of the other downhole valve assembly(ies) during deployment of the object in the well.

  • Publication number: 20150361747
    Abstract: A technique that is usable with a well includes using untethered objects to operate a first plurality of tool of the string and using a string-conveyed tool to operate a second plurality of tools of the string.

  • Publication number: 20130324444
    Abstract: The current application discloses methods and systems for preparing a wellbore treatment fluid precursor consolidated as one or more solid bodies; delivering the solid bodies to a logistics facility; and preparing a wellbore treatment fluid from the solid bodies. In some embodiments, the wellbore treatment fluid is a fracturing fluid for conducting a hydraulic fracturing operation on a subterranean formation penetrated by a wellbore.

  • Publication number: 20120285695
    Abstract: 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.

  • Publication number: 20070215345
    Abstract: A technique that is usable with a well includes deploying an assembly into a wellbore. The assembly includes at least one sensor. A fracturing fluid is injected under pressure into the wellbore to hydraulically fracture a subterranean formation of interest. The technique includes isolating the sensor from the fracturing and measuring acoustical energy that is generated by the hydraulic fracturing using the sensor(s).
