Analytical Formulae For In-Situ Combustion

Proceedings of SPE Improved Oil Recovery Symposium, 2010
Summary There is a renewed interest in using combustion to recover medium- or high-viscosity oil. Despite numerous experimental, numerical, and analytical studies, the mechanisms for incomplete fuel combustion or oxygen consumption are not fully understood.

Comparative combustion kinetics for in situ combustion process

Thermochimica Acta, 1999
Abstract In this research, thermal characteristics and combustion kinetics of three crude oils (13–27°API) were investigated using DuPont 9900 thermal analysis system (TG/DTG). A sample size of 10 mg, heating rate of 10°C min −1 were used in the temperature range of 20–700°C under air atmosphere.

In Situ NMR Spectroscopy of Combustion

Journal of the American Chemical Society, 2003
The first successful in situ studies of free combustion processes by one- and two-dimensional NMR spectroscopy are reported, and the feasibility of this concept is demonstrated. In this proof-of-principle work, methane combustion over a nanoporous material is investigated using hyperpolarized (hp)-xenon-129 NMR spectroscopy.

In Situ Combustion with Metallic Additives

SPE Latin America Petroleum Engineering Conference, 1992
Abstract In-situ combustion is the most energy efficient of the thermal recovery methods. In light oil reservoirs, too little fuel may be deposited thus making combustion impossible while in heavy oil reservoirs too much fuel may be deposited thus ruining the economics of the process. A research program has been initiated to try to solve

Reversein situ combustion

Zeitschrift für angewandte Mathematik und Physik, 1959
Fur den Fall einer hinsichtlich Temperatur und Partialdruck des Oxydenden nichtlinearen Quellenfunktion wird die in-situ-Verbrennung von Rohol untersucht. Die Warmeubertragung wird in ihrer Abhangigkeit von den Mechanismen der Konvektion, der Leitung und des Warmeubergangs zwischen festem und Gaszustand erortert.

Automation of an In-Situ Combustion Tube and Study of the Effect of Clay on the In-Situ Combustion Process

Society of Petroleum Engineers Journal, 1982
Abstract A fully automated in-situ combustion apparatus supported by a minicomputer was designed, constructed, and tested. Results obtained from four adiabatic dry combustion runs to investigate the effect of clay on crude oil combustion are reported.

In Situ Visualization for Large-Scale Combustion Simulations

IEEE Computer Graphics and Applications, 2010
As scientific supercomputing moves toward petascale and exascale levels, in situ visualization stands out as a scalable way for scientists to view the data their simulations generate. This full picture is crucial particularly for capturing and understanding highly intermittent transient phenomena, such as ignition and extinction events in turbulent ...
