Application of Hydroxyethyl cellulose HEC in oil drilling

Hydroxyethyl cellulose HEC can be used as thickener and cementing agent for well intervention fluid.  A low fixed content solution that helps to provide clarity, thus greatly reducing structural damage to the well.

Liquids thickened with hydroxyethyl cellulose are easily broken down by acids, enzymes or oxidants, greatly improving the ability to recover hydrocarbons.  Hydroxyethyl cellulose is used as a proppant carrier in well fluids.  These liquids can also be easily cracked by the process described above.

Drilling fluid with hydroxyethyl cellulose can effectively improve drilling stability due to its low solid content.  These performance suppressor fluids can be used for drilling medium to high hardness rock layers and heavy shale or mud shale.  In cement reinforcement operations, hydroxyethyl cellulose reduces hydraulic friction of mud and minimizes water loss from lost rock formations.
