Spreading Oil, Spreading Conflict? Institutions Regulating Arctic Oil and Gas Activities

An Investigation of Oil Spreading Coefficient in Carbonated Water+ Gas + Oil System: an Experimental Study in an Iranian Asphaltenic Oil Reservoir

To provide supplementary oil recovery after the primary and secondary processes, enhanced oil recovery (EOR) techniques are introduced. Carbonated water injection (CWI) as an EOR method can improve sweep efficiency and the risk of gas leakage. On the other hand, the interfacial tension (IFT) is one of the key factors which can affect fluid displacement during the process of CWI greatly. Therefo...

Oil, Conflict, and Stability

According to existing literature, the presence of oil leads simultaneously to increased risk of civil conflict and exceptional regime stability. The seemingly contradictory nature of these findings—oil leading both to instability and stability—has never been systematically addressed. Cataloging the causal mechanisms underlying both relationships, I demonstrate that hypotheses linking oil to civ...

Gas-oil Ratio and Water-oil Ratio

An indicator of bypassing is a premature drop in gas-oil ratio; i.e., earlier than expected collapse of gas saturation. Early gas collapse (water fillup) may indicate that channeling has occurred. In layered reservoirs with no or little vertical crossflow, water injection in an initially depressurized layer will cause GOR to drop rapidly. Often naturally fractured reservoirs exhibit fast gas co...

Oil and Gas Extraction

Spreading of an Oil-in-Water Emulsion on a Glass Plate: Phase Inversion and Pattern Formation.

Rigid blade coating of glass plates by oil-in-water emulsions stabilized by surfactants is studied. Complete surface coverage is obtained only for speeds exceeding a threshold velocity dependent on the height between the blade end and the surface. Below this threshold, the emulsion can be inverted in the vicinity of the blade. The inversion dynamics of the oil-in-water emulsion and the depositi...
