  • Patent number: 11828161
    Abstract: A first type of coupon holder includes an elongated core that is axially aligned with a coupon holder axis and an external surface that circumscribes the elongated core. The external surface defines coupon mounting surfaces with different radial orientations relative to the coupon holder axis. The coupon mounting surfaces are circumferentially aligned around the elongated core and have geometric centers with the same axial position along the coupon holder axis. A second type of coupon holder includes an elongated support structure that is axially aligned with a coupon holder axis and a coupon holder body positioned to have an end face in a plane transverse to the coupon holder axis. The coupon holder body has a plurality of slots to receive end portions of coupons. The slots are in a circular arrangement around the coupon holder axis and position coupons in parallel to the coupon holder axis.

  • Publication number: 20210332685
    Abstract: Methods for performing a hydraulic fracturing operation are provided. The methods include pumping a hydraulic fracturing fluid through a wellbore into a subsurface formation, in which the hydraulic fracturing fluid comprises a plurality of proppants. Individual proppants of the plurality of proppants travel a first distance into the subsurface formation and have a persistent diameter homogeneity. The methods further include shutting in the wellbore to facilitate crushing individual proppants under formation pressure to form microproppants and resuming pumping the hydraulic fracturing fluid after crushing individual proppants and forcing the microproppants to a second distance within the subsurface formation, in which the second distance is beyond the first distance relative to the wellbore.
