Mechanical rock properties prediction in Niger DELTA

New empirical correlations connecting rock strength and compressibility to accompanying petrographic and petrophysical data have been developed using a database of core-derived mechanical properties measurements. These empirical data are translated into predictive methods for determining mechanical qualities from geophysical wire-line records using automated fitting procedures. 600 triaxial compressive strength experiments of sandstone-to-shale lithotypes, as well … Read more

modelling of drilling fluid loss from nanoparticle modified drilling fluid from a non-darcy equation

Drilling fluid must fulfill various functions with a great impact on the drilling performance. Drilling fluid invasion can cause formation damage. Good quality mudcakes can prevent such damage. This research focuses on the lab techniques and performance results of testing innovative water-based drilling fluids containing nanoparticles (NPs) for minimizing formation damage at high-pressure/high-temperature (HP/HT) conditions. … Read more

MODELLING AND SIMULATION OF TRANESTERIFICATION OF WASTE VEGETABLE OIL (FRYING OIL) IN A BATCH REACTOR

MODELLING AND SIMULATION OF TRANESTERIFICATION OF WASTE VEGETABLE OIL (FRYING OIL) IN A BATCH REACTOR ABSTRACT In this study a kinetic model was developed to represent the kinetics of transesterificiation of waste vegetable oil (frying oil) in a batch reactor at different isothermal conditions of 313 K, 323 K, 333 K and 338 K. The … Read more

PRODUCTION OF BIODIESEL FROM WASTE VEGETABLE OIL USING EGGSHELL BASED CATALYST

PRODUCTION OF BIODIESEL FROM WASTE VEGETABLE OIL USING EGGSHELL BASED CATALYST ABSTRACT The production of biodiesel from waste vegetable oil using eggshell based catalyst was studied.
