Abstract (2. Language):
The characterization of a tropical bentonite (Niger
delta bentonite) has been performed by different techniques
for drilling application. While the chemical elements was
determine qualitatively by measuring characteristic radiation
of the X-ray fluorescence, the powder diffraction XRD of a
random powder mount was used to obtain the definitive clay
and nonclay components. The SEM was used to determine the
particle size and geometry. The optimum sodium carbonate
addition was observed between 2 and 3% which balance the
exchangeable/surface cation such that a ratio of 56:23:21 for
Na:Ca:Mg indicated a promising rheological property if the
clay is applied for viscosity builing in any industrial
application. The mixed monovalent divalent cation saturation
in its crude state tends toward a better swelling index desired
for drilling application with sodium carbonate activation. The
clay mineral was found to be chemically stable, having a
balanced surface charge distribution and the particles are
highly colloidal with unique atomic structure as of a typical
bentonite. The clay is a calcium bentonite and the chemical
analysis reflects that an economical peptizing route is
achievable.
