Dv. Yannimaras et Dl. Tiffin, SCREENING OF OILS FOR IN-SITU COMBUSTION AT RESERVOIR CONDITIONS BY ACCELERATING-RATE CALORIMETRY, SPE reservoir engineering, 10(1), 1995, pp. 36-39
This paper introduces a new method to screen crude oils for applicatib
ility of the air-injection/in-situ combustion process. Testing is perf
ormed at reservoir conditions, up to 41.4 MPa, with a specially modifi
ed accelerating-rate calorimeter (ARC(TM)). ARC results are shown for
four medium- and high-gravity oils, combustion-tube data is presented,
and air-injection field data are discussed and compared. We interpret
that the continuity of the ARC trace ties in kinetics, combustion-tub
e, and field air-injection results. Thus, a method is available to del
imit the envelope of applicability of air-injection/in-situ combustion
to those oil reservoirs where the probability of technical and econom
ic success is greatest.
