    May 15, 2019 · In addition to applying diverters more so than in previous completion designs, Chaparral is now testing dissolvable frac plugs to use in place of traditional plugs. Walker said dissolvable frac plug technology has improved over previous iterations while the costs have come down to a point where their use is more justifiable.

  • Sand Plugs Isolate Frac Stages in Barnett Well | Hart Energy

    Sand Plugs Isolate Frac Stages in Barnett Well. ... A number of techniques can be used to isolate segments of the well bore for treatment, but technology and economics constrain the number of segments that conventional plug-and-perf or frac sleeve systems can isolate effectively. To eliminate those constraints and maximize fracture growth ...

  • Fracking takes some balls - Texas Sharon's Bluedaze

    The balls and seats get progressively larger in size as you move up the wellbore so you can drop ple balls, and frac ple stages. It's an alternative to setting plugs or packers in the well to separate stages, eliminating the drill-out stage and making the completion quicker. Here are some info sheets from Halliburton & Schlumberger

  • Estimates of Hydraulic Fracturing (Frac) Sand Production ...

    May 26, 2015 · About 69 percent, by weight, of the proppant used in the Basin was frac sand, 24 percent was ceramic, and 7 percent was RCS (PacWest, 2014b). The high heat and pressure associated with wells developed in the deepest part of the Williston Basin limits the use of frac sand to well depths of about 2,500 meters (m).

  • Fracking has new balls. - Texas Sharon's Bluedaze

    Way back in 2011, I told you that Fracking takes some balls–big balls of steel that sometimes fall from the sky. This little known hazard of fracking created an entrepreneurial opportunity. Now fracking has new, improved, high tech balls that ruin the entrepreneurial opportunity. This part is worrisome: Dissolve rates can be increased through the [.]
