Supervisory Control And Data Acquisition (SCADA) systems have been widely used in industry applications. Due to their application specific nature, most SCADA systems are heavily tailored to their specific applications. For example, a remote terminal unit (RTU) that monitors and controls a production well in an oilfield is only connected with a few sensors at the well it resides. The RTU usually...

Determining injector-producer relationships, i.e., to quantify the inter-well connectivity between injectors and producers in a reservoir, is a complex and non-stationary problem. In this paper, we present a neural-network-based sensitivity analysis approach to address this problem. To the best of our knowledge, sensitivity analysis has never been applied for identification of the injector-prod...

The Carboniferous Karashayi Formation in Tahe Oilfield is one of the most promising formations field clastic rocks Oilfield, which rich hydrocarbon resources, but stratigraphic framework unclear, restricts exploration formation. features and seismic section analysis area combined with oil gas distribution are used to analyze reservoir control factors Formation. results show that lower part sedi...

Oilfield chemicals are utilized in treating reservoir formations, wellbore completions, drilling, and to enhance productivity, which exerts pressure on the formation. Pressure from these processes cause formation rock weaken, weakened begins detach, thereby producing sand as well fluid (petroleum). In petroleum industry, sanding poses major challenges with significant financial consequences. Th...

The development history and principle of interwell tracer testing single-well were investigated, the application conditions advantages different analyzed through analysis two types technologies test results in production process SMi oilfield with medium porosity low permeability, so as to provide reference for study same type oilfield. Tracer technology can master connection between injection w...

The BZ 34-1 oilfield is a typical gas cap edge water reservoir in the Bohai oilfield. main characteristics of were multi-phase sand body stacking and was composed three parts: cap, oil reservoir, water. actual production site results show that permeability difference multi-layer bodies has serious impact on development effect. This article establishes model numerical based total recovery degree...

for this study, asmari (oligo-miocene) and bangestan (cretaceous) reservoir oils from themarun oilfield were studied geochemically. gas chromatograms and stable isotopes of carbon and sulfur indifferent oil fractions were studied. normal alkanes nc15+ are as high as 93% with a saturate percentage up to53.9% which reveal a high maturity of asmari and bangestan reservoir paraffinic oils. carbon p...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...
