After the cement was allowed to set up, 500 sacks of barite <br /> <br />were prepared and pumped into the well to a depth of l89 feet, after which <br /> <br />400 sacks of cenent were prepared and pumped into the well at the same <br /> <br />depth and allowed to set up. Two hundred fifty sacks of cement were then <br /> <br /> <br />prepared and pUnll'ed into the well to a depth of lea feet and allowed to <br /> <br />set up. The remainder of the well was then filled with'the cement slurry <br /> <br />and plugging of the well was completed August 3, 1968. 1'.0 thousand two <br /> <br /> <br />hundred and sixty sacks of cement and 1,500 sack" (150,000 lbs.) of bar- <br /> <br />itc were used to plne the well. <br /> <br />The contractor moved to the Piceance Creek 'Tell on August 5, 1968, <br /> <br />,and at 1 p.m. removed the valve from the casing.
