During the general history matching process, the production data that are commonly assimilated are oil production rate and water cut, etc. The geochemical data, which have been regarded as important information source, are rarely integrated...

.... This leads to a reduction in heat loss to the overburden and a decline in oil production rate. This study examines the question of optimal well pair spacing in relation to the formation thickness and in-place oil. The effect of other variables on SAGD performance is investigated. A case study was performed...

... patterns, reservoir heterogeneity, and permeability anisotropy on optimal WAG ratios. Optimal is defined as being at minimal net CO 2 utilization ratios or maximal oil production rates). Simulations of CO 2 EOR show that the optimal WAG ratio for the ROZs is less than 1 (ratio of injected water and CO 2...

The novelty of the proposed ensemble-based approach is forecasting...

... chamber rise velocity and oil production rate during this period is developed. In this theory, by combining volumetric oil displacement with Darcy oil rate considering the indirect frontal instability effect, the rise velocity, and the steam chamber height are calculated. The model is extended to predict...

... from produced oil was observed after the CO2 breakthrough as a result of the increase in pressure gradient within the core before the CO2 breakthrough. However, oil production rate dropped significantly after this period because of low residence time of CO2 in the porous medium. Continuous CO2...

... Abstract Solvent vapour extraction (VAPEX) has shown great potential to recover heavy oil reserves. However, the application of the VAPEX technique is limited by its low oil production rate, which is caused by the slow mass transfer and inefficient gravity drainage. Hence, increasing the heavy...

Matching parameters include oil production rate, GOR, flowing bottom-hole-pressure (BHP), saturation profile, and reservoir...

.... Results show that (1) foamy oil could effectively re-saturate the solvent chamber; (2) more pressure pulses would lead to more oil production, while the oil production decreases with pulse number in one cycle; (3) the oil production rate of PP-CSI is 4.37 times of that of conventional CSI, and the final...
