Drilling polymer is a high molecular weight aqueous
solution that controls fluid loss and increases
viscosity.
GLO
DP 1000
Description:
It is a co-polymer of anionic character and
high molecular weight. It is a water soluble polymer
which is primarily used as a highly efficient
fluid loss reducer, viscosifier and protective
colloid for shales and cutting in fresh water,
calcium, sodium brines and KCL mud systems. It
is compatible with most of the drilling fluid
products, biopolymers, PAC, CMC etc. It maintains
hole stability by preventing shale swelling and
erosion.
Application:
It maintains viscosity in solid free drilling
fluid. As a bentonite extender in low solids non-dispersed
mud, it can be used along with small addition
of bentonite to suspend weight material.
COMMON NAME - PARTIALLY HYDRAULISED
POLY ACRYLAMIDE (PHPA)
Advantages:
- It functions as an inhibitor by coating or
encapsulating formation & cuttings.
- It also restricts the interaction of water
hydratable & dispersable shales.
- 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.
