2. Drilling fluids are essentials drilling muds Used in oil well Drilling activities. And clear brine fluids are the salt mixtures that are used as completion, workover, and packer fluids in the drilling operations. The use of clear brine fluids is many fold, thus they are used extensively in various oil and gas exploration activities. Uses of Clear Brine Fluids: Solids-free clear brines have become well-established as completion and workover fluids because of their ability to maximize formation productivity. Clear brine fluids are used as completion and workover fluids that are pure solutions consisting of salt dissolved in water. These clears brines, in order to function properly must be kept stable at the surface and downhole conditions. Brine fluids are used in preparation of oil well equipment including screens, liners, packers, etc. Selection a clear brine fluids for oil well drilling and completion operations is a very complex process. Fluids tend to react chemically with the produced gases and oil additives, this causing damage to the formation in the form of corrosion or stress cracks. Besides these technical issues, the world economy has also been a contributing factor in the selection of clear brine fluids for onshore and offshore oil drilling activities. Clear brine fluids are versatile in nature. The use of clear brine fluids include as a displacement fluid to discard the drilling wastage. They are also used as permanent packer fluids or drilling fluids. Proper selection of a combination of inorganic salts like calcium bromide, sodium bromide, zinc bromide, calcium chloride, etc, formulates a better balance in the nearby wellbore pressures found in the oil well field. Brines also facilitate faster penetration rates, improved well bore stability, better hole gauge, shale sections, etc. Thus, understanding of the chemical nature of the brines is essential in selecting cost effective oil well fluids. Drilling fluids: This fluid is very important fluid in oil and natural gas drilling process. This fluid is essential in drilling a wellbore because: It acts like a coolant and a lubricant. It prevents the wellbore hole to shut. Maintains the formation pressure and prevents various formation fluids like oil, gas, and water to enter the wellbore before time. It effectively removes the rocky surface by pushing the bits of rocks back to the surface. http://www.cscpl.com

3. Types of Drilling Fluids: Drilling muds (another name for the fluids used in drilling activities) have several types based upon the drilling conditions. These types include: 1.Water-based Fresh water based Salt water based 2.Oil-based 3.Synthetic materials With the advancement of technology, the oil industry have successfully developed many oil-like synthetic materials which provide high performance drilling like fluids. The common types of these materials include: Poly alpha olefins Internal olefins Synthetic paraffins Ethers Vegetable Esters Linear alkylbenzenes 4.Air and foam fluids those are less dense in nature. Drilling Muds have several essential additives. These additives are usually liquid or solid and do not mix well with air and foam like of drilling liquids. These additives include corrosion inhibitors like iron oxide and zinc carbonate, surfactants like soaps, foams, and fatty acids, biocides like amines, weighing materials like barite, and fluid loss reducers like starch and polymer. http://www.cscpl.com
