Oilfield Chemicals Manufacturer | CHEMCON

Basically, when it comes to the oil and gas exploration processes, there are lots of complexities involved as the oil and natural gas need to be drilled out from deep under the earth’s surface and hence, there are chances of contamination of the actual material that is coming out of the process. Several highly advanced equipments are being used for these offshore drilling processes and therefore, there are also high probabilities of these getting damaged owing to too much friction with the various types of earthly particles that always come in the process of drilling of the different types of hydrocarbons deep inside the surface of the earth.

Type of Chemicals

In order to take care of all these factors, the oilfield chemicals come as handy solutions for the petroleum industries because these not only provide a useful solution but are also extremely environment friendly at the same time. The Properties of Oilfield Chemicals are mainly responsible for making these indispensable during the process of drilling of oil and natural gas and some of these include density, specific gravity, pH content, ionic composition, etc. This is mainly because the chemicals are actually inorganic salts such as clear brine solutions that are in no way harmful for the environment unlike any other chemical component and so, the pollution factor can also be avoided with the usage of such types of chemicals. This is perhaps the reason behind the maximum manufacture of these chemicals by the chemical industries of the world and India as well.

Sodium Bromide Solution & Calcium Bromide Solution

One of the most important chemicals beings used and manufactured by the chemical industries today is sodium chloride solution that is also commonly called brine solution. It is physically a clear and colorless fluid that is available in powder form and in solution also. Along with this, calcium chloride solution is prepared as well by the chemical industries to be utilized in the oil and gas exploration processes. The common characteristic of both these types of chemicals is the compatibility with the surface while the drilling process is going on. This not only averts any kind of chemical reaction with the substances being drilled out but also takes care of the hydraulic pressures and well pressures in order to prevent the backflow of the substances at the same time.

Both Sodium Bromide Solution as well as Calcium Bromide Solution can be used singly or with other salts as double salts for attaining some desired specific gravity, density, etc. as required by the drilling processes. These chemicals offer a very cost-effective approach for the petroleum industries as compared to any other counterparts for the complex process of oil and gas exploration processes. Hence, these are manufactured in a widespread manner by the Indian chemical industries and the products are in high demand in India as well as abroad.

Benefits and uses of Hexamethyldisiloxane

As stated, Hexamethyldisiloxane (HMDSO) is an organic silicon compound which is primarily used as a solvent and as a reagent in organic synthesis. However, apart from these HMDSO is also used for several other purposes. They are:

1. HMDSO is an internal standard for calibrating a chemical shift in 1H NMR spectroscopy. The purpose of using HMDSO is because it can be easily handled as it is less volatile than the usual tetramethylsilane, yet displays only a singlet near 0 ppm.

2. HDMSO is used to crystallize highly lipophilic compounds since it carries a poorer solvating power than alkanes.

3. This compound is also used in manufacturing liquid bandages that comes in spray format, like a cavilon spray. These generally protect damaged skin from irritation caused by other bodily fluids.

4. HDMSO acts as a good anti-adhesive agent and hence, they are used to remove any residue left by medical tapes, bandages and any other adhesive materials.

5. Presently, studies are conducted to use HDMSO in making low-k dielectric materials for the semi conductor industries.

6. HDMSO is a highly hydrophobic compound, so it exhibits high gas solubility. This is the reason that it possesses a strong nuclear magnetic resonance spin lattice relaxation rate (R1) response to changes in oxygen tension (pO2). For the presence of this quality, HDMSO has been used as a reporter molecule in the process of measuring tissue oxygen tension (pO2).

7. When HDMSO is directly injected in the tissue, it can generate maps of tumor and muscle oxygenation dynamics with respect to the hyperoxic gas breathing challenge.

Hexamethyldisiloxane is one of the most sought out silicon compounds in the market. Chemcon Specialty Chemicals Pvt. Ltd. is a revered Hexamethyldisilazane Manufacturer in India and you can be assured that you will be receiving top quality silicon compounds.

Use Of Hexamethyldisilazane As A Pharmaceutical Chemical

Pharmaceutical chemicals are used for benefitting human as well as animal health. They may be discharged into the environment, even if in the minutest levels, through their manufacture, use and disposal. Many scientists all over the world are trying to discuss the effects of this release on the environment. We already have a large array of pharmaceutical products and every year newer products are being added. The active ingredient in every drug or medicine is a pharmaceutical chemical. They have a separate biochemical mode of action and therefore one has to strictly consider the effects of these active ingredients on the flora and fauna.

Manufacture of pharmaceutical chemicals

Manufacture of the pharmaceutical chemicals normally takes place in two stages. It is either manufacturing them in bulk or manufacturing the finished drug product. Good manufacturing practices or cGMPs are responsible for minimizing any kind of unnecessary excipient into the environment. All pharmaceutical manufacturing facilities are subject to various kinds of restrictions or schedules, compliant to the rules and regulations pertaining to processed or non processed effluent discharge. There are restrictions on rates, quantities and concentrations of physical, biological and other constituents.

The Use Of Hexamethyldisilazane As An Alternative In The Analysis Of Ambers

Amber’s physical properties can be used for production of tools, ornaments and various works of art. If derivatisation techniques are used for the transformation of the polar pyrolysis products into less polar and more volatile compounds, Tetramethyl ammonium hydroxide can be used. This improves the analytical performance and the detection limits of the technique. It allows for the hydrolysis and the methylation to be done simultaneously. Very recent developments silylating reactions are done with the help of Hexamethyl Disilazane or HMDS which has also been proposed to be the alternative of amber. HMDS comes with great potentials as compared to the strongly alkaline TMAH reagent. The main limitations of this derivatizing reaction are related to the occurrence of the secondary reactions. These secondary reactions include decarboxylation reactions which are undergone by carboxylic acids as well as the formation of the dehydration products and other by products. These reactions produce pyrogams which are very tough to interpret.

Other Uses Of Hexamethyldisilazane

The use of HMDS as a drying agent was beneficial in the specimen preparation for scanning electron microscopy imaging of bacterial surface colonization on sub bituminous coal. The ability of the microbes to biofragment, ferment and generate methane from coal is where HMDS comes to use. It acts as a very good alternative to critical point drying in the imaging of cells on coal. Thus there is no need for very expensive equipments. Coal can be easily fragmented into sub-micron particles which can create a problem in critical point drying procedures. Both individual and aggregated cells appear in good shape with the least occurrence of the flat cells. This is the importance of the use of HMDS in cell attachment studies on sub-bituminous coal. The use of HMDS drying is a much preferred technology over the most commonly used CPD method as it is not only safer and cheaper but also more practical as method.

The Requirement of Oilfield Chemicals and their Preparation

Oilfield Chemicals a Specialized Chemical:

Apart from developed equipments, there are specialized chemicals known as oilfield chemicals that find prominent use in these projects. Consequently, the demand for these chemicals is ever increasing and therefore, the preparation, packaging and distribution of such types of chemicals are being taken up by the oilfield chemical manufacturers in order to meet the needs of these chemicals in the market. India is well-known for the manufacture of such chemicals and the chemicals prepared here are widely circulated in various parts of India as well as abroad. There are certain specific chemicals like calcium bromide (CAS No.7789-41-5) that is very popular choice of chemical component for the petroleum industries and hence are manufactured in large quantities in India.

On-Shore Drilling Activities:

The offshore drilling activities as well as the on-shore drilling activities related to oil and gas exploration projects have evolved from the earlier conventional processes to the modern times where science and technology find massive use altogether. Starting from the standard of the chemicals like work-over fluids or specialty chemicals to the mechanism used with the equipments, every single sphere of the process has undergone an all-round development. Simultaneously, the processes have transformed into being more safe, sound and eco-friendly. Along with that, these have also become extremely economical too that adds on to the profitability of the exploration projects.

Several by-products are produced during the oil and gas drilling processes and one such by product is salt water. This is again kept aside in disposal pits along with some residual oil that remains along with the salt water. Afterwards, the oil being skimmed out of the salt water and only this portion of oil constitutes almost 40% of the total revenue of the companies. Oilfield chemicals are therefore extensively used in order to simplify the processes of exploration and some of these chemicals include zinc bromide, sodium bromide, sodium chloride, calcium bromide and the like. These salts are either used singly or in combination with other salts based on the specific needs of the projects.

Oil and Gas Operations:

These are also known as completion fluids sometimes that help in controlling well-bore pressures during drilling activities in upstream oil and gas operations. Calcium bromide (CAS No.7789-41-5) is one such fluid that can be used single or with other salts to get fluids of varied densities at different crystallization temperatures. It is basically a clear and colorless liquid that looks transparent and sometimes comes with a pale yellow color also. This is a very important chemical used in lots of exploration processes in a very cost-effective and environment friendly manner that makes it one of the most sought after chemicals of petroleum industry.

The essence of oil drilling chemicals in oil exploration projects

It becomes extremely essential on the part of the companies to take care of several factors while manufacturing these chemicals. This is because the percentage of composition of the compound will define their characteristics that will in turn vary in its action during the course of oil and gas exploration. The various features that are exclusively common in the oil drilling chemicals are:

• Presence of abundant suspension properties so that the drilled cuttings can be easily transferred to the top of the exact sites where the exploration is being done.

• The solids on the surface must not get dispersed in the chemicals at any cost or else this may come in the smooth way of oil and gas exploration and hinder the efficiency of the process as well by damaging the production zone.

• Since the oil and gas are explored by boring wells, hence the hydrostatic pressure has an important role to play here. The chemicals are responsible for the exertion of such pressure that in turn helps in the creation of balance in the pressure so that no other fluids come in the way of oil exploration. This requires the chemicals to have a specified density and specific gravity too.

• Apart from the above-mentioned features, these fluids are also helpful in maintaining appropriate well-bore stability as well. The companies have to take care of the density and other relevant chemical properties of the chemical fluids while the preparation process so that these can easily help in controlling the optimum level of formation pressures that is necessary to maintain while oil and gas exploration. In fact, along with the chemical properties, the physical properties of the chemicals also play a major role in the preparation process because this will also define the stability of the process over a certain period of time.

• Any sort of damage can be averted with the help of these Oil Drilling Chemicals such as zinc bromide and sodium bromide solution.

 

• In addition to all these, these chemicals are also vital for lubrication purposes. This is important because enormous amount of heat is generated during the drilling process and in order to compensate for the after-effects like friction, etc. these fluids are very much helpful because their circulation inside the well-bore lubricates the whole assembly and the pipe that in turn facilitates a smoother movement of the process altogether.

Fluids like Sodium Bromide Solution is one of the main chemicals that is dominantly used in these projects because all the above-mentioned properties are present in this chemical and it can be used as a single solution and mixed with other chemical compounds as well.

Importance of Completion Fluids in Oil and Gas Exploration

Unique Clear Brines:

Oil and gas industry makes use of special types of fluids called clear brines which help in the completion of an oil well. Ideally there shouldn’t be any solids in the liquid which are salt solution made with the addition of one or more salts. These liquids are used to minimize damage to the well bore and to provide stability to the well. Brine solutions are given more preference over mud because of the salt content which mixes with water rather than forming suspension which settle after a certain period of time.

Clear brines are salt solutions which are usually mixture of bromides, chlorides and formats. They have the required density and characteristics which are necessary for completing oil and gas extraction safely. There ionic composition is high and there pH value is also on the higher side. These liquids are identical to reservoir formation chemically. Oilfield chemicals are not used for ordinary purposes because they are expensive and corrosive.

Oilfield Chemicals:

Completion fluids are used widely in oil and gas exploration by various companies who take up these projects. These liquids are used when the drilling process is towards the end and while testing the well. The fluid is introduced into the well to help ease the operations before the production of hydrocarbon is started. This enables reduction of friction between the equipment and the wall and of the well. It controls the temperature from rising due to fiction and prevents the equipment from damage.

A vast amount of study and research is employed in studying drilling fluids. The success of drilling operations depends a Great Deal on Completion Fluids. Up to 100% success can be achieved with this selection of right type of fluid for billing purposes. Therefore, it is important to understand the chemistry of drilling fluids while choosing oilfield chemicals.

Zinc Bromide Crystallization:

One of the commonly used liquids is Zinc Bromide (7699-45-8) which is used as a work over fluid and a completion fluid. It is used when the required density is 19.2lb/gal. It is usually mixed with calcium bromide or calcium chloride to get varied densities as per the wellbore conditions. Fluids created in this manner can be manufactured for various crystallization points and can also be used for special applications as well as for winter use. To get therequired density and crystallization temperatures he blending table should be consulted.

It should be stored in appropriate corrosion resistant containers and should be closed and sealed ensuring there is no leakage. Since it is a hygroscopic salt solution which absorbs water from the atmosphere, the density of the liquid will go down if exposed to air. Caution should be exercised while handling and all safety measures should be taken as prescribed by the manufacturer.
