How Does Polymer Drilling Fluid Help?

Polymer drilling fluid commonly known as polymer fluid is a type of drilling fluid that is used for drilling through reactive formations where the primary concern is shale inhibition. Moreover, glycols, salts, and amines that are not compatible with bentonite are frequently used shale inhibitors.

They are used to drill reactive formations where shale inhibition requirement is significant. These systems derive the extent of viscosity from polymers such as fluid loss control and xanthan gum from starch or derivatives of cellulose.

Use of Polymer Drilling Fluid in Construction

Polymer drilling fluid is usually used for construction with heavy equipment in places where shell inhibition is significant. It helps in strengthening the wall cake and further prevents caving and sloughing in the hole. There are other benefits like hole-cleaning and improvement in viscosity. 

Moreover, the liquid polymer has low molecular weight and is mostly designed to break down clay swelling, hydration, and expansion. The main function of the fluid is to provide hydrostatic pressure to prevent formation fluids from making their way into the bore of the well and keep the drill bit cool and clean during the process of drilling.

Types of Polymer Drilling Fluid

Several different types of polymer drilling fluids are classified on their composition and use. Three key factors, Cost, Technical performance, Environmental impact. Water-based fluids are the most commonly used systems, which further fall into two categories – dispersed and non-dispersed. Then comes Saltwater drilling fluids, Oil-based fluids, and further polymers such as Xanthan gums and potassium chloride used as base brie for polymer, based fluids.

Advantages of Polymer Drilling Fluid

Polymer-based fluids when used, improve core recovery, helps in minimizing formation damage, retain a near gauge hole, and also reduce costs of transportation and preparation. The best polymer drilling fluid is chosen depending upon the situation.

Conclusion

So, if you are trying to search for companies that provide top polymer drilling fluids near you, the basic criteria for choosing the right company would be basically -It should be cost-effective, Thermal stability of the fluid, Good customer reviews.
