Application in:shale stabilization,viscosities,friction reduction,fluid loss control and lubrication
PHPA Advantages:
It functions as an inhibitor by coating or encapsulating formation & cuttings.
It also restricts the interaction of water hydratable & dispersible shale's.
It can be used as a flocculent in clear water drilling.
It also provides inhibition properties to fresh water, sea water and also in presence of calcium ions.
High viscosity of this drilling fluid helps in better removal of cuttings from bore hole.
It is resistant to bacterial fermentation.

More Application Of PHPA
Certain types of polymers have been used successfully for many years in oil fields as drilling mud additives for viscosity modification shale inhibition/clay stabilization and fluid loss control. A wide range of products is available to suit the particular type of water based drilling mud system used by the operator to achieve the optimum performance. Each specific application is given below:
