In modern drilling operations especially in extended-reach or horizontal wells managing friction and torque is one of the most persistent technical challenges Excessive friction can lead to high energy consumption tool wear and even wellbore instability One highly effective solution that engineers are increasingly turning to is oilfield polyacrylamide
This water-soluble polymer known for its strong viscosity-modifying and lubricating properties plays a crucial role in reducing mechanical drag between the drilling string and the borehole wall especially in complex and deviated wellbores

Key Friction and Torque Problems in Complex Wells

Drilling Challenge and Impact on Operations

High Drag in Extended-Reach Wells limits depth reduces tool life

Excessive Torque on Drill String increases risk of mechanical failure

Unstable Borehole in Shale Zones leads to stuck pipe or washout

Poor Hole Cleaning causes accumulation of cuttings and increases resistance

How Oilfield Polyacrylamide Works

Polyacrylamide modifies the rheology of drilling fluids increasing lubricity while maintaining proper viscosity It reduces metal-to-rock contact allowing for smoother rotation and better hole cleaning Its polymer chains also enhance the suspension of cuttings which further minimizes the frictional load on the drill string

Key contributions of oilfield polyacrylamide include

Lowering dynamic and static friction coefficients

Improving hole cleaning and cuttings transport

Reducing torque fluctuations during rotary drilling

Enhancing mud cake quality for borehole stabilization

These effects lead to safer faster and more cost-effective drilling in technically demanding formations
