The friction related to bit wear, torque and drag greatly hinder the efficiency for a drilling operation. Colloidal carbon beads, synthesized by a facile solvothermal method, are investigated as an additive for improving the tribological performance. The application and tribological behavior of carbon beads as lubricant additives in water-based drilling fluid are estimated following a standard API/Baroid lubricity tester., the lubricity coefficient of composites of bentonite and carbon beads is lower even at a concentration of 0.2% (wt) compare to the concentration of 3% (wt) graphite powder. The coefficients of friction of carbon beads at different concentrations in water under 1.0 N normal load show significant improvement in its lubricity, reduced about 48% at the concentration of 0.8% (wt) compared to pure water. The rolling mechanism similar to nano or micro scale ball bearings of carbon beads can be pro-posed to account for the lower friction and wear performance.Keywords

The kinetics of combustion of oil shale by different oxygen contents(11,21,42 and 63% Vol.) has been investigated by thermogravimetric analyzer (TGA) at three different heating rates (10,30 and 50°C/min). The Activation energy E of oil shale thermal decomposition under different oxygen concentrations were determined by iso-conversional method (Kissinger-Akahira-Sunose (KAS) method and Flynn–Wall-Ozawa (FWO) method). The data obtained from TG was used to calculate the Activation energy and discuss the influence of oxygen concentration on kinetic parameters. According to the TG results, the combustion process of oil shale could be divided into three stages, the evaporation of water, the combustion of the decomposition of organic matter and combustion of semicoke. The TG revealed that the oxygen content in atmosphere does not affect the evaporation stage but influence the combustion stage. The results show that the average activation energies were 134.85, 163.41, 211.19 and 242.32 KJ/mol. Activation energy using KAS method were 136.50, 167.37, 216.49 and 225.38 KJ/mol, whereas the FWO method at different oxygen contents were: 11,21,42, 63 vol%,respectively. The results of kinetic calculation revealed that the activation energy values of the combustion increase with increase of oxygen content.Keywords
