Abstract
This research paper assesses the effect of
temperature on the rheological properties of Water-Based
and Oil-Based Muds. The Muds were formulated with locally
sources barite from 5 locations in Nigeria.Third order
polynomial models have been considered to model the
rheological properties as a function of SG (Specific gravity)
which were generated using least square method and
regressed with the Excel GRG (Generalized Reduced
Gradient) Non-Linear Forward derivative solver. The
absolute mean percentage error of the model data and
measured data were calculated for all rheological properties
and WBM 10” Gel strength had the highest error of 6.578%
followed by OBM Yield Point of 4.443%. WBM Plastic
viscosity showed the least error of 0.315%, seconded by
WBM 10’ Gel strength with error of 0.339%. Findings from
this work indicated that barites Samples B3 and B5 are good
barites for WBM formulation as their rheology withstood
increasing temperature the most and B4 is better for OBM
formulation. Also, B1 and B2 will be good for OBM
formulation if beneficiated to increase its SG and remove
impurities.
