Drilling Fluids Activities:
Drilling oil and natural gas wells is most challenging activity due to high temperature and pressure. Drilling fluids helps a lot in dealing such drilling activities. They helps by holding back pressure, removes drilling cuts from down the well, acting as coolant for drilling bits, exerting its pressure on walls of wells and thus helps in drilling, and thus preventing the shutting of drilling wells before time.
Oilfield Chemical Importance:
Drilling fluids are the outcome of advance technology and developments. But for them to function properly they must be kept stable not only at surface but also deep down the earth. Also for their advantageous use their proper selection for purpose of use is also important. Hence Speciality Oilfield Chemicals like calcium bromide, Zinc bromide, and Sodium bromide are available. Out of which proper selection of oilfield chemical is important to support cost effective projects of drilling. Such selections are very important as oilfield chemicals must not react chemically with oil or gas that is to be drilled. Otherwise it may lead to corrosions. This issue can be solved by adding anticorrosive additives like iron oxide which prevents corrosion.
Along with advantages and profitable usage of drilling fluids, they must also be environmentally non- damaging and eco-friendly for use. If not their disposal would be a major problem to deal with and the cost of disposal with directly affect the cost of projects. Thus the speciality chemicals in the oilfields available now a day are eco-friendly in nature.
Applications of CaBr2:
Calcium bromide is widely used drilling fluid in oil and natural gas industries. The importance of calcium bromide is that it is important for those oil industries whose main aim is to deliver quality. Calcium bromide is white powder having chemical formula CaBr2. Along with controlling pressure of oil and natural gas wells it is has versatile applications like it is used for freezing mixtures, for photography, as food preservatives, fire retardants, for neuroses medications etc.
Mixture of Calcium Bromide:
On top of all Importance of Calcium Bromide increases due to its easy availability with all manufacturers and that too available in all sorts of scale. One of the important reasons behind using calcium bromide is that it easily mixes with other zinc and calcium brines. Calcium bromide prevents hydration of clays and its migrations thus preventing corrosion of oil flow lines and thereby preventing any delay in production. Moreover it is chemically and thermally very stable which is a great advantage.
However the storage and handling of Calcium bromide require great deal of attention. It is hazardous in nature so must be handled after wearing proper protective equipments.
