Can polyacrylamide mud be used for loss circulation treatments?

Development of a polyacrylamide-based mud formulation for loss circulation treatments J. Energy Resour. Technol., Trans. ASME, 143 ( 7) ( 2021), 10.1115/1.4048682 Performance of water-based drilling fluids for deepwater and hydrate reservoirs: designing and modelling studies Petrol.

What is polyacrylamide used for?

Hence, it is an earth-stabilising fluid that is designed for a variety of applications in the geo-construction industry such as tieback anchors, diaphragm walls, horizontal drilling, tunnelling, slurry trenching, drilled shafts/bored piles, and others. 6.1. Polyacrylamide in drilling technology

Is Anan a good polymer for drilling fluid?

Due to its superior fluid loss control properties, the P (ANAN) can be a promising polymer for water-based drilling fluid in deep and ultra-deep well drilling applications. Drilling fluid in the drilling process can be seen as the equivalent to the blood in the human body [ 1 ].

Can an anionic polymer withstand drilling fluid?

The fluid loss test on this drilling system found that anionic polymer can resist about 4.5 × 105 ppm of Cl −, 4 × 105 ppm of Ca 2+, and 1.5 × 104 ppm of Mg 2+ at low pH by adding the acidic gas together at 180 °C. Thus, it can withstand the temperature of drilling fluid up to 180 °C.

How polyacrylamide (PAM) is used in sewage treatment?

In sewage treatment, using polyacrylamide (PAM) can increase the recycling rate of water reuse. In petroleum extraction, polyacrylamide (PAM) is mainly used in drilling mud materials and for enhancing oil recovery, widely applied in drilling, well completion, cementing, fracturing, enhanced recovery, and other oil field extraction operations.

Is an anionic polymer an anti-high temperature and anti-salt contamination fluid loss control additive?
