Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...

In this research the experimental and theoretical studies on different Enhanced Oil Recovery (EOR) techniques, i.e. Water Flooding (WF), Gas Injection (GI) and Water Alternating Gas process (WAG) were performed on specimens taken from an Iranian carbonate offshore reservoir at the reservoir condition. The experimental results for each specified techniques were compared with the correspondin...

co2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. in this study, the lower part of es1 reservoirs in pucheng oilfield was introduced as the target reservoir. by studying the minimum miscible pressure in co2 flooding, the reservoir could achieve miscible flooding. long core displacement experiments prove...

Polymers increase the macroscopic efficiency of flooding process and crude oil recovery. The viscosity 3 polymers xanthan, guar, Arabic gums is measured in lab experimented with as EOR options. Xanthan guar gum are weight percentages 0.1, 0.2, 0.4, 0.5, 1, while 5, 10, 15 percentages. experiments showed that had lowest at 15% wt. significantly higher viscosities than corresponding At same 0.5%,...

Core flooding experiments are used for testing enhanced oil recovery strategies (EOR) on a laboratory scale. In a typical core flooding experiment, the core plug contains oil, water and potential EOR agents. It is of importance to understand the multiphase flow of these liquid inside the porous rock formation. The combination of X‐ray CT scanning and image analysis has been used to study multip...

This paper presents a simple and robust mechanism called SYN-dog to sniff SYN flooding sources. We install SYN-dog as a software agent at leaf routers that connect stub networks to the Internet. The statelessness and low computation overhead of SYN-dog make itself immune to any flooding attacks. The core mechanism of SYN-dog is based on the protocol behavior of TCP SYN—SYN/ACK pairs, and is an ...

Sequence stratigraphy is the study of genetically related facies within a framework of chronostratigraphically significant surfaces, where the depositional sequence is considered to be the fundamental unit for sequence-stratigraphic analysis (Van Wagoner et al., 1990). The depositional sequence is defined as a genetically related succession of strata bounded by unconformable surfaces and their ...

Use of microemulsion in enhanced oil recovery has become more attractive in recent years because of its high level of extraction efficiency. Experimental investigations have been made on characterization of microemulsions of oil-brinesurfactant/cosurfactant system for its use in enhanced oil recovery (EOR). Sodium dodecyl sulfate, propan-1-ol and heptane were selected as surfactant, cosurfactan...
