Additional disposal optionsĪfter adding up your fluid and disposal costs, it is time to evaluate equipment options that may provide an opportunity to reduce out-of-pocket expenditures. You also have to estimate the distance between the job site and disposal facility, as well as the fuel and labour costs involved in making the round-trip. You will want to look into where these sites are located and estimate how much you will have to pay to use them.īut do not forget, the disposal costs are not your only expense. Today, many projects require HDD fluids to be disposed of at licensed facilities, and the costs associated with dumping can vary greatly. To begin, you must research all local regulations about disposing of drilling fluids. The 45-degree outlet manifold on the R250C reclaimer, combined with the use of the suction breakers, separates sand and course silt efficiently Once you know how much fluid is needed, the next thing to determine is how to correctly dispose of the spoils afterwards. Keep in mind that harder rock usually requires more fluid per bore distance.Ĭalculating the cost and the amount of additives and water you will require ahead of time will not only ensure you are tracking the expenses on the project but will also help determine what equipment will be needed on the job. In reactive clay, you will probably have to use a polymer additive. In sand or cobble, you will likely only need a mixture of bentonite. Ground conditions dictate the drilling additives you will need, and the amount of fluid required. The estimating process should include evaluating ground conditions at the job site, the type of drilling additives you will need, and the volume of fluid required for the project. The latest addition to the line is the Vermeer MX300 mixing system, which features a redesigned, slim rectangular profile tank and a power unit that can be paired with up to two tanks at one time to help decrease the time spent refilling fluid tanks. To help with the mixing process, Vermeer offers several mix systems, appropriately sized for the directional drill a crew is running. Proper mixing and testing of your fluids should still be done for the best results." However, with the newest pre-packaged liquid concentrate additives, sometimes people think they can pour it into the water tank with minimal stirring. "With powders, you can see if an additive hasn't been properly mixed. "Whether contractors are buying bags of bentonite or have made the switch to liquid drilling additives in pouches, using a mixing system is crucial," says Michael. There are numerous benefits to using drilling fluid with every bore, but to get the maximum benefit from the additives, it should be adequately mixed. "Adding some type of additive to the water will help reduce the risk of premature tooling wear," Michael says.Īlso, water lacks the viscosity to maintain hole integrity or float drill cuttings out of the hole. Water offers very little lubrication, which means there is more drag and friction on drill rods and the drill head. On projects that require large volumes of fluid, bringing in a reclaimer can help reduce the amount of fluid and additives used by removing solids and recycling fluids
