  • Publication number: 20230023606
    Abstract: A system and method for treating a subterranean formation. The method may include utilizing a diluted stream and a high-loading stream which are combined to form a diverting composition. The diverting composition may then be injected into a wellbore. The system may include devices to prepare the diluted stream and high-loading stream, combine the streams, and introduce the combined stream into the wellbore.

  • Publication number: 20170174976
    Abstract: A degradable composite composition including polyglycolic acid and a boron-containing accelerator, and methods of using the same (for example, as a constituent of a treatment fluid of a subterranean formation) are described. The degradable composite composition may be a composition that degrades in environments typically encountered downhole, such as oilfield environments/conditions and/or fluids.

  • Patent number: 9593565
    Abstract: Systems and methods for handling wellsite packets for a wellsite are provided. The wellsite packets include soluble packaging with wellsite materials therein. The wellsite has surface equipment and downhole equipment positioned about a wellbore. The handling system includes at least one feeder, at least one mixer, at least one metering device, and a pump. The feeder moves the wellsite packets directly or indirectly into the mixer. The mixer stimulates dissolution of the soluble packaging so as to mix the wellsite materials with a fluid to form a wellsite mixture. The metering device selectively controls the number of wellsite packets moving to the mixer. The pump is operatively coupled to the mixer to pump the wellsite mixture at the wellsite.

  • Patent number: 9410394
    Abstract: A method of treating a subterranean formation comprising generating a fracture in the subterranean formation, introducing a predetermined amount of proppant into a treatment fluid, and subsequently introducing a plugging agent into the treatment fluid before the entire predetermined amount of proppant reaches the fracture, minimizing overdisplacement of the proppant from the fracture.
