  • Compositions and methods for increasing fracture conductivity
    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

    Date of Patent: January 7, 2020
    Assignee: Schlumberger Technology Corporation
    Inventors: Dmitriy Ivanovich Potapenko, Leland Ramsey, Timothy M. Lesko, Dean M. Willberg, Theodore Lafferty, John W. Still
  • Well operations
    Patent number: 10119378
    Abstract: The disclosure pertains to methods for completing a well may comprise lowering a coiled-tubing in the well thus forming an annulus between the casing and the coiled-tubing, pumping down said annulus a treatment fluid above the fracturing pressure of the formation while also pumping fluid through the coiled tubing. The methods may also comprise monitoring in real-time the bottom hole pressure and increasing the pump rate through the coiled-tubing if an increase of bottom hole pressure is observed.

  • In situ channelization method and system for increasing fracture conductivity
    Patent number: 9523268
    Abstract: A method and system for increasing fracture conductivity. A treatment slurry stage has a continuous first solid particulate concentration and a discontinuous anchorant concentration between anchorant-rich substages and anchorant-lean substages within the treatment slurry stage.
