...% A.e., saving 20,000 mmbtu/ of steam in a year, generating an increase in the OSR of 0.12 BBl / MMBTU; and a decreasing the number of well services jobs from 51 to 27. This result was achieved because areas with oil saturation that had not been previously stimulated in the conventional process of CSS...

... the estimation of input parameters for reservoir simulation. A sector model taken from a 3D full field static-dynamic model was used to simulate the effect of surfactant-polymer (SP) flooding over the residual oil saturation, which has almost already been reached in Puesto Hernandez field. The SP formulation...

... the main technique historically for estimating oil saturation behind casing, given its salinity independency. In order to achieve a desirable statistical precision and accuracy, carbon-oxygen data with slim tools requires several logging passes over the zone of interest. A typical acquisition strategy...

... and that there was remaining oil to be recovered both by the reduction of the residual oil saturation to water or by improving the vertical sweep efficiency. The sector chosen was around a well that has an excellent quality core and which is also the region with the highest production in the field. One of the borders...

... Abstract It is now widely acknowledged that continuous oil spreading films observed in two-dimensional glass micro-model studies for strongly water wet three-phase oil, water and gas systems are also present in real porous media and result in lower tertiary gas flood residual oil saturations...

... at 10 bar. The main purpose of this study was to survey the influence of clay content in the reservoir rock with initial oil saturations ranging from 25 to 50%. The results indicate that the in-situ combustion method is technically applicable to the rock-fluid system tested. Moreover, the tests were...

These experiments were initialized at oil saturations and conditions representative of those in a steam chamber. The residual oil saturations were determined from a full-hole core taken in the vicinity of a mature SAGD...
