Petrophysical evaluation of petroleum reservoirs is one of the most challenging tasks for hydrocarbon reserve determination. One critical petrophysical parameter is the water saturation which is normally calculated from Archie’s equation. Carbonate reservoirs, however, due to their complex mineralogy are not good candidates for Archie’s equation because Archie’s parameters are strongly dependen...

Alkanes are the major components of crude oil and the most abundant and available carbon and energy sources in reservoirs. Microorganisms are common inhabitants of these environments and may have effective biodegrading strategies, based on specialized enzyme systems and metabolic pathways, as a form to access hydrocarbons as carbon and energy sources. However, the current knowledge of the micro...

Under the guidance of petroleum geology, on basis in-depth understanding geological characteristics D block such as structure and sedimentation law oil gas enrichment, this paper discusses reservoir potential selects target block. The study shows that is a fault nose controlled by reverse normal fault, has controlling effect its provenance, formation distribution.

The present article exhibits the achieved results based on evaluation of two petroleum systems, which compares reservoirs fluvial environments sedimentary basins located in south and north Atlantic, Brazil (Recôncavo Basin) Portugal (Lusitanian Basin), respectively. main contribution this study is survey static (source, reservoir, sealing rocks, addition to traps) dynamic elements (tectonic, mi...

The present study comprises physicochemical and phytochemical evaluation of arial parts of Eclipta alba in different extracts using ethanol, petroleum ether, benzene, chloroform and aqueous solvents by using standard methods. The physical evaluation was carried out for the determination physiochemical profile such as ash values and extractive values, whereas phytochemical evaluation was carried...

It is well known that reservoir simulation studies are very subjective and vary from simulator to simulator. While SPE benchmarking has helped accept differences in predicting petroleum reservoir performance, there has been no scientific explanation behind the variability that has frustrated many policy makers and operations managers and puzzled scientists and engineers. In a recent book by the...

Reservoir simulation is routinely employed in the prediction of reservoir performance under different depletion and operating scenarios. Usually, a single history matched model, conditioned to production data, is obtained. The model is then used to forecast future production profiles. Since the history match is non-unique, this is essentially an inverse problem. Hence the forecast production pr...
