In the Niger Delta, low oil recovery rates less than 30% results mainly due to production problems such as water coning, wax deposition and high gas/oil ratios. Meanwhile, remaining becomes a good candidate for EOR methods CO2 injection, polymer foam in-situ combustion steam injection. But it stands, practice of these known enhanced is scarce in Nigeria’s Oil Gas industry. However, this project...

The integrated injection-production string is the core tool used in thermal recovery wells for heavy oil, mechanical behavior of which complex due to coupling effect downhole temperature and pressure load induced by steam huff puff operations. In this paper, an analysis model that calculates field during operations has been established based on basic principles energy conservation heat transfer...

Due to increasing global energy demand and the fact that a major source of required is generated from fossil fuels, combustion process has turned into topic interest in converting fuels energy. An ideal system one can combine high engine efficiency with low fuel consumption emissions. Increasing humidity technique used by researchers for influencing process. The present study aims review previo...

Steam solvent co-injection processes are generating considerable interest in terms of improving heavy oil upgrading unconventional reservoirs. The characteristics the opted solvents field have not been dealt with depth. This paper presents a study on selecting most optimal for Akan oilfield enhanced recovery (EOR). first step this work consisted determining viscosity, through an elemental and S...

In line with the decarbonisation of power sector, carbon-free fuels are currently being investigated. particular, green ammonia or e-ammonia is a candidate fuel which will be playing key role in many energy-intensive industries. It calls for an in-depth understanding eFuels combustion characteristics flexible combustors. Therefore, present work first time numerically investigates regimes steam-...

It is necessary to establish effective communication between two horizontal wells during the preheating period of steam-assisted gravity-drainage (SAGD). However, time usually very long, which results in high steam consumption and CO2 emissions. There little research on effects different wellbore fluids period. The heat transfer heating characteristics fluids–water, heat-conduction oil, air–wer...
