Oilfield Industry Application Guide
● HEC thickening agent can be used as thickner of the well workover fluid and cementing agent. Help to provide clarification of the low fixed content solution, thus greatly reducing the structural damage to the wells. The liquid thickening by Hydroxyethyl Cellulose can be easily decomposed by acids, enzymes or oxidants, greatly improving the ability to recover hydrocarbons.
● Fluid in the well, HEC is used as proppant carrier. These liquids can be easily cracked through the process.
● HEC configuration using drilling fluid, based on its low solids content, can effectively increase drilling stability. These properties can be used to inhibit the fluid medium to high hardness of the rock and heavy shale or shale drilling.
● Reinforcement in the cement operations, HEC can reduce the hydraulic friction, minimize the loss of rock and water loss.

- Q: If I accidently put and oil leak additive in my gas what will happen?
- depends on how much additive and how much gas? If anything the gas will break down the oil additive and your car may or may not smoke a lttle (kind of like engine oil getting in gasoline.......... I would not worry too much, fill up your tank and dilute the additive as much as you can exhaust may smell funny, beyond that I dont think any permanent damage would occur.Keep in mind, accidents happen, and with one additive looking like another and the fact that there is a huge bunch of crap available to pour in almost any orifice in your car, people make mistakes. I was at a major big box retailer, and its like the latest thing now to have this huge variety of crap in target., or walgreens, or safeway, I had a friend who is using the green syrup for Nyquil that there are like 6 different companies with one name or another. I thought I was looking for a green liquid sleeping aid, my friend didnt mention she was using the green liquid similar to nyqul until later after going to 4 stores looking for a sleep aid that came in a green bottle It became apparent I needed more information. And of course had she said from the beginning had they sad it was the generic cold medication it would have been a no brainer.you cannot change it now , about all you can do is run it throgh the tank of gas.

- Q: What are the common food additives
- Common chemical additives are preservatives sorbic acid, colorant caramel color, sour agent citric acid, lactic acid, etc. In fact, these chemical additives have a scientific name and common name of the points, of course, is the use of common name. Now the public because there is a smell of preservatives and discoloration of the psychological, so businesses in the food recipe to write its common name is also promising. We have to oppose the intentional speculation of some businesses, such as a moon cake packaging marked with a line of words: "This product will not contain preservatives," there can be a line below the small word "sodium benzoate", but in its There are sorbic acid in the formula. It is not without preservatives, but does not contain preservative sodium benzoate, the same is still a preservative. This is the intention of business speculation. As well as some vegetable oil manufacturers in their products marked "this product will not contain cholesterol", in fact, all the vegetable oil is not cholesterol. They want to advertise can write "vegetable oil does not contain cholesterol", but they write "this product will not contain cholesterol" to give people an illusion that only their products do not contain cholesterol, and other vegetable oil contains cholesterol. These are businesses deliberately speculation.
- Q: Its not in the back of my genetics book, but my prof uses the term.
- Firestone/Bridgestone. They are less expensive and won't give you any problems.
- Q: Fred Meyers offers a .10 discount per gallon of gas but I‘ve never seen them advertise any type of fuel additives like Chevron‘s Techroline. Additives such as Techroline helps prevent fuel deposits and carbon build up inside the engine, valves, and fuel injectors. I have often wondered if FM sells their gas cheaper because it does not contain any beneficial additives. Can anybody clarify this? Thanks.
- It doesn't have techroline but most gas stations don't have theses additives either. I think most if not all gas stations now have 10% ethanol additives (not benficial but it is an additive).
- Q: Which friends know where the year of the month by the start of food additives or fragrance spices please tell me what I really can not find Thank you

- Q: My mom asked me if I‘m on drugs today. Like, she honestly asked me, and of course I said no. Because I would never do something like that. So then I proceeded to lock myself in my bedroom, drowning in my tears, so hurt that she would think I‘m on drugs.and she told me she‘s sorry. Then she said that she recently read about how there are additives put into our food, and it can manifest itself in our bodies like drugs do. Is she right, or am I just a crazy person? Because I KNOW I‘m not on drugs.
- Some additives can affect people who are sensitive to them, but I don't think it's your food. You live with your mom, so I'm guessing you're a teen? This is NORMAL behavior for a teen. Your hormones are at the strongest they'll be in your life, and they can definitely make you spaced out at times, as well as super emotional. Don't worry, your hormones will normalize and your emotions and brain will all settle down and start to work a lot better in a few short years!
