Can potassium chloride mud be used in sloughing?

Field application of the polyacrylamide/ potassium-chloride mud has beensuccessful in stabilizing hard, sloughing potassium-chloride mud has been successful in stabilizing hard, sloughing shales in Canada and in reducing shale-related hole problems in several offshore areas.

Can polyacrylamide/clay nanocomposite be used as drilling fluid additive?

The troublesome shale formations need special formulation of drilling fluids having high shale inhibition characteristics to mitigate wellbore instability problems. In the present study, polyacrylamide/clay nanocomposite (PANC) was synthesized and used as drilling fluid additive.

What is potassium based mud used for?

A potassium-based polymer mud has been used successfully forcontrolling troublesome shales in many wells around the world. Shale stability results by combining potassium chloride with a high-molecular-weight, partially hydrolyzed polyacrylamide.

How is polyacrylamide/clay composite synthesized?

Polyacrylamide/clay composite was synthesized by free radical polymerization. Synthesized composite had good filtration control properties in drilling mud. High shale recovery was obtained with synthesized composite.

Can potassium chloride solve wellbore instability problems in shale Reservoir Drilling?

To solve wellbore instability problems in the shale reservoir drilling process, potassium chloride (KCl) has been incorporated into the drilling mud as drilling fluid additive [, , , , , ].

Does potassium chloride reduce hydration of shale?

Potassium chloride (KCl) is usually used as inhibitor to reduce hydration of shales. In this study, we investigated the inhibitory efficiency of KCl on shale through a series of experiments, including dynamic linear swelling (DLS) tests and uniaxial compressive strength (UCS) tests, to provide reference for the design of WBMs.
