Selection Criteria Of Drilling Fluids5/28/2022 The most important criterion when creating a drilling fluid plan is the minimum cost for the overall well. Production and exploration concerns environmental impact as well as logistics and performance are others factors which are involved in drilling fluids chemicals suppliers. These factors affect the development of drilling fluid programs. We'll discuss them below. Environmental ImpactWhen making plans and installing drilling fluid, environmental issues remain important. For example in offshore drilling mineral or synthetic oil is used more than diesel oil-based systems. 2-Drilling can be generally classified into two categories that are exploratory and development operations. Geological conditions may be used to optimize other programs, like hydraulic design, as well as to assist in designing the drilling chemicals suppliers. program. The data available on the area is not sufficient to design the mud properties. The mud system designed been designed to help in getting the geological data quickly and safely. In the event of any unexpected problems or changes, the mud composition has to be able to change rapidly. Problems related to Formation Types The anhydritic form of the drilling fluid bentonite may cause calcium ions to be released in the mud system. This could slow down the bentonite's hydration and may cause the loss of fluid. There are two ways to deal with the presence of ions. You can either eliminate them from the mud systems using sodium carbonate (Na2Co3) or transform the IRO oildrilling into an inhibitory system. High Temperature Environment Drilling at high temperatures can decrease the effectiveness of chemical additives, and can cause the loss of fluid and changes in viscosity. Drilling fluids that are resistant to these conditions can be used like the oil-based drilling mud systems. Pressure formation If drilling through unusual pressure formations, fluids can flow into the mud system, causing mud contamination or undesirable kicks. To prevent such issues it is essential to plan for the proper mud weight. Loss Flow Periods Drilling fluids could be lost into the formation. This is categorized as partial loss circulation as well as total loss circulation. The flow rate from the outlet to the hole is lower than the flowrate at the inlet. In the second scenario the mud is not taking place on the surface. If the fracture pressure is too high when drilling fluids circulate or if the formation is naturally fractured so that mud can flow through it, then lost circulation may occur. Shale Many issues can arise during drilling in the intervals of shale. It is possible to list them as follows: Mechanical pipe sticking - High torque and drag -Hole cleaning problems -Boring liquid contaminants Drilling Rig The choice of drilling fluids can be limited by the mud control system (solid control system and chemical treatment) as well as the available hydraulic horse power within the circulator system. Attaining the goals set could be directly linked to the choice of rigs and the layout of the rig. Casing Program The drilling depth is dependent on several aspects, including the changes in pore pressure trend Geometries, geometries and the separation of problematic regions. These criteria are also utilized in the design of the drilling fluid program. Optimizing the drilling fluid program could allow drilling longer sections, which can lower the cost of drilling overall. Water Requirements The availability of water used to make the drilling fluid must be considered when designing for the drilling mud program. If the water used to make the drilling fluid is available on site, then diluting can be the most economical treatment. If, however, the water is brought to the rig site, optimizing the control of the solid is the best choice. Corrosion The drill string could fail by the combination of corrosion and mechanical cyclic loading. Drill pipe life is greatly diminished by the presence of dissolved gases like H2S and CO2 in drilling fluids.
