Recommended 1. Pour pellets slowly from surface to minimize bridging of pellets. Break <br /> Treatment up bridges as they occur. <br /> 2. Pellets can be tremied into place when necessary. Volume needed can <br /> vary by as much as 10 to 15 percent in a rotary drilled hale. <br /> 3. Calculate and monitor pellet addition amounts to ensure proper hole fill <br /> by measuring the position of the top of the plug after every few pails. <br /> 4. Calculated volume should be applied to borehole. <br /> Volume/Amount of BAROID BENTONITE PELLETS Required For <br /> Grouting and Plugging Applications <br /> Nominal Hole Pounds of PELLETS needed to fill <br /> Size Volume, gal/ft 1 ft <br /> (inches) ft'/ft 1/4" 3/8" 1/2" <br /> 3 0.049 0.37 3.5 3.5 3.3 <br /> 4 0.087 0.65 6.2 6.2 5.9 <br /> 4'/z 0.110 0.83 7.8 7.8 7.4 <br /> 5 0.136 1.02 9.7 9.6 9.2 <br /> 5'% 0.165 1.23 11.7 11.6 11.1 <br /> 6 0.196 1.47 13.9 13.8 13.2 <br /> 7 0.267 2.00 19.0 18.8 18.0 <br /> 7'h 0.307 2.30 21.8 21.6 20.6 <br /> 77/8 0.338 2.53 24.0 23.8 22.7 <br /> 8 0.349 2.62 24.8 24.6 23.4 <br /> 8'/2 0.394 2.95 28.0 27.7 26.4 <br /> 8% 0.417 3.12 29.7 29.4 28.0 <br /> 10 0.545 4.10 38.7 38.4 36.5 <br /> 11 0.660 4.94 46.9 46.5 44.3 <br /> 11'/: 0.721 5.40 51.2 50.8 48.4 <br /> 12 0.785 5.88 55.8 55.3 52.6 <br /> 12'% 0.818 6.12 58.1 57.6 54.8 <br /> 12^% 0.852 6.37 60.5 60.0 57.1 <br /> 123/4 0.886 6.63 62.9 62.4 59.4 <br /> 17% 1.623 12.14 115.23 114.3 108.7 <br /> 171/2 1.670 12.49 118.6 117.6 111.9 <br /> 24 3.141 23.49 223.1 221.2 210.5 <br /> 26 3.686 27.60 261.8 259.6 247.1 <br /> 30 4.907 36.70 348.5 345.6 328.9 <br /> 36 7.066 52.85 501.9 497.6 473.6 <br />
