Abstract:
The effects of guar gum polymer and lime powder addition on the fluid loss and rheological properties of bentonite dispersions have been investigated. Elevendifferent formulations have been prepared according to the American Petroleum Institute procedures and their rheological characteristics have been determinedusing a rotational viscometer. Four rheological models have been used to describe the pseudoplastic behavior of the dispersions. It has been observedthat all rheological properties increase with pH and show a maximum at pH value of about 11.5. The effect of addition of lime also extremely increases the fluid loss of bentonite dispersions.
