B. Mill certificates and supplier material specifications attesting to the chemical and physical <br /> characteristics of each casing material. <br /> C. Manufacturer specifications and material data for all cement, bentonite, litter park. concrete. <br /> and well appurtenances to be installed with the well. <br /> D. Two copies of geophysical log,and electronic .LAS or.CSV file formats. <br /> PART 2 PRODUCTS <br /> 2.1 WELL DRILLING MATERIALS <br /> A. Equipment <br /> 1. General: <br /> a. All equipment shall be the proper type and shall be in good condition to assure that <br /> the Work can proceed without interruption and that the drilling of a plumb and <br /> straight boring results. For rotary drilling, a portable fluid tank with a shale shaker, <br /> desilters, and desanders fully capable of handling the capacity of fluid system shall <br /> be used to remove all but the finest of drilling cuttings from the drilling fluid. This <br /> equipment shall keep the sand content below three (3) percent by volume in the <br /> drilling fluid at all times during the drilling process. Excavated pits will not be <br /> allowed for use in managing drilling fluid. Drilling equipment, including collars. <br /> stabilizers and/or couplings shall be of sufficient size, strength. and design to <br /> maintain plumbness and alignment in drilling a nominal 10 to 14-inch borehole to a <br /> target depth of approximately 200 feet. <br /> 2. Drill Rig: <br /> a. Contractor shall provide a rig equipped to drill by appropriate method that enables <br /> installation of plastic well casing without deformation of casing material. <br /> b. The drill rig shall have a primary mud pump and fluid system that are built as <br /> integrated units connected to the drill rig. <br /> c. The drill rig shall be capable of drilling 12 to 14 inch diameters. <br /> d. The drill system will be completely water tight from drill bit to cyclone discharge so <br /> that all cuttings and formation water are discharge at a singular location near the rig <br /> through the cyclone separator. <br /> 3. Mud Pump: <br /> a. The pump used to circulate the drilling fluid shall have sufficient capacity to maintain <br /> an ascending velocity of at least 150 feet per minute for the drilling fluid in a nominal <br /> 12 to 14 inch diameter borehole. <br /> 4. Mud Pit/Cleaner: <br /> a. Portable mud tank equipped with linear motion shaker tables and de-sanding cones. <br /> b. Mud systems equipped with orbital motion shaker tables will not be acceptable. <br /> c. The portable mud pit will have a minimum capacity of 1000 gallons. <br /> d. Excavated mud pits will not be allowed. <br /> B. Drilling Fluids <br /> I. Clear water drilling is prohibited. <br /> 2. The drilling fluid shall possess such characteristics as required to adequately maintain the <br /> walls of the borehole, to prevent caving ol'the well as drilling progresses, and to permit <br /> recovery of representative samples of cuttings. <br /> GRINDSTONE JOE'S SUMMARY OF WORK <br /> REPLACEMENT WELL, 01 11 00-2 lune 25,2019 <br />
