... and lowering oil viscosity. The present investigation reports the results of extensive experimental and theoretical work (with the aim of computer software, ECLIPSETM) to determine the viscosity and swelling factor changes of the live oil in the Cheshmeh Khoshk reservoir at southern of Iran (Ilam District...

... Abstract Natural gas transport and storage in coal is important for accurate predictions of production rates from coalbeds. Recent investigations based on nondestructive imaging have shown that coals are complex materials exhibiting nonuniform pore structure. Standard approach to describe gas...

... Abstract The paper presents basic data on Enhanced Gas Recovery (EGR) by gas-gas displacement for nearly depleted natural gas reservoirs, by injecting waste gases. The soundness of the concept of gas-gas displacement for enhancing gas recovery was investigated via laboratory investigations...

... be obtained by extending the analysis into modeling. Field examples will be presented to highlight the methodology. A rigorous technique for estimating the radius of investigation during the test will be discussed. It will be shown that in the presence of measurement errors, radius of investigation will grow...

Chemical corrosion to the casing has been a consistent challenge to the industry starting from the very beginning of the petroleum industry which put steel casings underground. The investigation reported here was initiated in an attempt to understand casing failure mechanisms...
