Run in hole with bit and scraper and clean out hole to <br /> T.D. using drilling fluid with the following properties: <br /> density - 72 lb./cu. ft. , viscosity - 40-45 sec./qt. <br /> 4 . Run in hole with open-ended tubing to T.D. Using balance <br /> method, place cement plug to fill to 200 feet above up- <br /> permost perforations. <br /> 5. Pump cement in 320 foot stages. Each stage to consist of <br /> 62 sacks of cement. Total cement will be 186 sacks of <br /> API class "G" cement with 2 percent CaC12 . Pull up and <br /> circulate until returns show clean mud. Shut-in well and <br /> wait on cement 6 hours. <br /> 6. Lower tubing and feel for top of cement. Record depth to <br /> hard cement for final abandonment report. <br /> 7. Pull tubing to a depth of 5, 400 feet and equalize another <br /> cement plug using 40 sacks of API class "G" cement with 2 <br /> percent CaC12 . Pull up to a depth of 4, 900 feet and cir- <br /> culate clean. Wait on cement 6 hours. <br /> 8 . Lower tubing and feel for top of cement. EPA to witness <br /> top of cement plug. <br /> 9 . Swab fluid level to 60 feet below ground level. Mix 12 <br /> sacks of API class "G" cement with 2 percent CaC12 and <br /> fill casing from a depth of 60 feet to ground surface. <br /> 10. Cut off conductor pipe and 10-3/4 inch and 7 inch casing <br /> at least 5 feet below ground level . Weld steel plate on <br /> top of 7 inch casing. <br /> 11. Remove cellar if present.
