CO₂-EOR Huff ‘n’ Puff Pilot Test in Rang Dong Oilfield, Offshore Vietnam

3d Analysis of Huff and Puff and Injection Tests in Geothermal Reservoirs

Heat extraction from deep, hot rocks for energy production is based on water circulation through a man made fracture or natural fractures. As multiple and non-planar fractures in a stress field affect the geothermal reservoir behavior, so the capability to simulate multiple fractures and joints is needed to help reservoir design and operation. A 3D model is developed in this work to simulate an...

Offshore Oilfield Development Planning under Uncertainty and Fiscal Considerations

The objective of this paper is to present a unified modeling framework to address the issues of uncertainty and complex fiscal rules in the development planning of offshore oil and gas fields which involve critical investment and operational decisions. In particular, the paper emphasizes the need to have as a basis an efficient deterministic model that can account for various alternatives in th...

An Experimental Investigation of Feasibility of Gas Huff and Puff for Recovering Crude Oil with Different Viscosities

Investigating multi cyclic gas (N2 and CO2) huff and puff have been conducted by long sandpack simulations with four different crude oils from Jiangsu oilfield. According to the production differential pressure and the production regularity during huff and puff, the production process was divided into three sections; the first one is free gas production section; the second section is low viscou...

Laboratory Study on EOR in Offshore Oilfields by Variable Concentrations Polymer Flooding

Results: The experimental results showed that the recovery of variable concentrations polymer flooding was higher than that of constant concentration polymer flooding, under conditions of same total amount of polymer and similar water flooding recovery. Its sweep efficiency and displacement efficiency were also significantly higher than those of constant concentration polymer flooding. Moreover...
